Why GAO Did This Study: 

In the past, governments worldwide owned, operated, and regulated air 
navigation services, viewing air traffic control as a governmental 
function. But as nations faced increasing financial strains, many 
governments decided to shift the responsibility to an independent air 
navigation service provider (ANSP) that operates as a business. As of 
March 2005, 38 nations worldwide had commercialized their air 
navigation services, fundamentally shifting the operational and 
financial responsibility for providing these services from the national 
government to an independent commercial authority. 

GAO selected five ANSPs—in Australia, Canada, Germany, New Zealand, and 
the United Kingdom—to develop, as requested, a descriptive analysis of 
commercialized ANSPs that illustrated similarities and differences in 
ownership, length of experience with commercialization, and size and 
scope of operations. 

This report addresses the following questions: (1) What are common 
characteristics of commercialized ANSPs in selected foreign countries? 
(2) What do available data show about how the safety, cost, and 
efficiency of air navigation services have changed since 
commercialization? (3) What are some key lessons learned about the 
commercialization of air navigation services? 

What GAO Found: 

The five commercialized ANSPs that GAO selected have a number of common 
characteristics: All five have the safe movement of aircraft as their 
primary goal and are subject to some external safety regulation. All 
five operate as businesses, making and carrying out their own 
strategic, operational, and financial decisions. As businesses, all 
five are self-financing, assessing fees on users of air navigation 
services (e.g., major commercial air carriers; regional air carriers; 
and, in some cases, general aviation operators) and, as necessary, 
borrowing funds from capital markets. Finally, all five are largely 
monopoly providers of air navigation services and undergo some form of 
constraint in setting prices, such as economic review or procedural 
guidelines. 

Available data from the five ANSPs indicate that since 
commercialization, the safety of air navigation services has remained 
the same or improved; each ANSP has taken steps to control costs; and 
each ANSP has reportedly lowered costs and improved efficiency through 
investments in new technologies and equipment. Despite concerns about 
the possibility that commercialization could potentially compromise 
safety, data from all five indicate that safety has not eroded. For 
example, data from New Zealand and Canada show fewer incidents 
involving loss of separation (the required distance between aircraft). 
All five ANSPs have taken steps to control their operating costs, 
whether by eliminating some administrative positions or by 
consolidating facilities. All five ANSPs have also invested in new 
technologies and equipment, which the ANSPs say have lowered their 
costs by increasing controllers’ productivity and produced operating 
efficiencies, such as fewer or shorter delays. However, the ANSPs have 
also increased fees for general aviation operators. 

GAO’s research points to a number of lessons. For example, 
commercialized ANSPs must be prepared to mitigate the effects of an 
industry downturn, whether through reserves, higher fees, cost-cutting, 
or other measures. Involving stakeholders in modernizing (i.e., 
upgrading or replacing) ANSP facilities and equipment can benefit both 
the ANSP and the stakeholders. Special measures may be needed to 
protect service to small or remote communities. Finally, when a 
government sells an ANSP’s assets, appropriate valuation is necessary 
to protect taxpayers’ interests.

Since 1987, 38 nations have commercialized[Footnote 1] their air 
navigation services, fundamentally shifting the responsibility for 
providing these services from the national government to an independent 
air navigation service provider (ANSP) that operates as a business and 
is designed as a performance-based organization.[Footnote 2] In the 
past, governments worldwide owned, operated, and regulated air 
navigation services, viewing them as a governmental function. But as 
nations were faced with increasing congestion, outdated equipment and 
facilities, and financial strains, many governments reevaluated their 
structures for providing air navigation services. Some nations decided 
that shifting the responsibility for operating and, in some cases, 
owning the services to an independent commercial authority could 
produce efficiencies that would benefit both users and the government. 
In general, the responsibility for regulating the safety of the 
services is independent of the ANSP and is still considered a 
governmental function. 

You asked that we develop a descriptive analysis of selected foreign 
countries' commercialized, performance-based air navigation service 
organizations. To do so, we asked the following research questions: 

* What are common characteristics of commercialized ANSPs in selected 
foreign countries?

* What do available data show about how the safety, cost, and 
efficiency of air navigation services have changed since 
commercialization?

* What are some key lessons learned about the commercialization of air 
navigation services?

To address these questions, we reviewed the characteristics and 
performance of five commercialized ANSPs, which we selected as 
illustrative of similarities and differences in ownership, length of 
experience with commercialization, and size and scope of operations. 
These ANSPs--Australia's Airservices Australia; Canada's NAV CANADA; 
Germany's Deutsche Flugsicherung GmbH (DFS); New Zealand's Airways 
Corporation of New Zealand, Ltd; and the United Kingdom's (UK) National 
Air Traffic Services, Ltd. (NATS)--were commercialized between 1987 and 
2001 and have been operating since then as performance-based 
organizations. Because we selected these ANSPs to illustrate certain 
characteristics, our results cannot be generalized to all 
commercialized ANSPs.[Footnote 3]

A performance-based organization develops strategies, goals, and 
measures and gathers and reports data to demonstrate its 
performance.[Footnote 4] The five ANSPs that we reviewed have been 
gathering and reporting data since commercialization, but their 
predecessor organizations did not necessarily gather or publicly report 
comparable data. Consequently, assessments of each ANSP's performance 
since commercialization are possible, but comparisons of performance 
before and after commercialization are generally not feasible. 
Additionally, opportunities for comparing performance across 
commercialized ANSPs are limited to the extent that the ANSPs define 
their measures of safety, cost, and performance differently. We 
determined that the financial and safety data from each country were 
sufficiently reliable for our purposes. For additional information on 
our scope and methodology, see appendix I. We performed our work in 
accordance with generally accepted government auditing standards from 
August 2004 through July 2005. 

Results in Brief: 

The five commercialized ANSPs that we selected for review have a number 
of common characteristics: All five have the safe movement of aircraft 
as their primary goal and are subject to some external safety 
regulation by an arm's-length government regulatory authority. All five 
operate as businesses rather than as government organizations, making 
and carrying out their own strategic, operational, and financial 
decisions. As businesses, all five are self-financing, assessing fees 
on users of air navigation services (e.g., major commercial air 
carriers; regional air carriers; and, in some cases, general aviation 
operators) and, as necessary, borrowing funds from capital markets, 
instead of receiving annual appropriations from the government. 
Finally, all five are largely monopoly providers of air navigation 
services and are constrained in the price-setting process by some form 
of economic review or procedural guidelines. 

Available data from the five ANSPs we reviewed indicate that since 
commercialization, the safety of air navigation services has remained 
the same or improved; each ANSP has taken steps to control costs; and 
each ANSP has reportedly lowered costs and improved efficiency through 
modernization--that is, through investments in new technologies and 
equipment. Despite concerns about the possibility that 
commercialization could compromise safety, data from all five indicate 
that safety has not eroded. For example, data from Canada, Germany, and 
New Zealand show fewer incidents involving loss of separation (the 
required distance between aircraft). Additionally, stakeholders told us 
that safety regulation improved when the regulator was separated 
organizationally from the ANSP. All five ANSPs have taken steps to 
control their operating costs, whether by eliminating some 
administrative and middle management positions or by consolidating 
facilities. Furthermore, all five ANSPs have invested in and benefited 
from new technologies and equipment, which the ANSPs say have lowered 
their costs by increasing controllers' productivity, and have produced 
operating efficiencies, such as fewer or shorter delays. As a result, 
some ANSPs have been able to lower the prices they charge the airlines 
for certain services. However, the ANSPs have also instituted or 
increased fees for general aviation operators, and some ANSPs have 
increased or plan to increase the costs of service to small or remote 
locations. 

We derived a number of lessons from our research on commercialized 
ANSPs. First, commercialized ANSPs must be prepared to mitigate the 
effects of an industry downturn through such measures as establishing a 
reserve fund, implementing a revenue-generating alternative to user 
fees, or cutting costs. Second, involving stakeholders in efforts to 
modernize (i.e., upgrade or replace) ANSP facilities and equipment can 
help to ensure mutually beneficial results. Third, the conflict between 
an ANSP's need to recover its costs and the inability of some users 
(e.g., regional air carriers) to pay the full costs of service to small 
or remote communities may mean that special measures are needed to 
protect service to such communities. Fourth, when a government sells 
its interest in an ANSP to private investors as part of the 
commercialization, the ANSP's assets have to be appropriately valued to 
protect taxpayers' interests and create a basis for sound financial 
decision making. Fifth, maintaining and attracting sufficient 
personnel, with the skills and expertise needed to ensure that the 
regulator can provide uninterrupted safety regulation is important when 
operations are separated from regulation during commercialization. 
Finally, developing baseline safety, cost, and efficiency measures 
prior to commercialization will allow the ANSP and others to assess the 
progress the ANSP is making toward its goals and evaluate the results 
of commercialization. 

Background: 

Before commercialization, air navigation services under government 
control faced increasing strains. Many were underfunded, as evidenced 
by freezes on air traffic controllers' wages and insufficient funds to 
replace aging technologies. Technology replacement programs often cost 
more, took longer, and delivered less than promised, and stakeholders 
complained about performance and customer service. In some instances, 
the country as a whole faced widespread fiscal problems and the 
commercialization of air navigation services was simply part of a 
larger movement to reform government enterprises. For instance, the New 
Zealand government established 14 state-owned enterprises in 1987, 
including air navigation services, rail services, and postal services. 
The government also reformed electricity as a state-owned enterprise in 
1994 and telecommunications in 2004. 

Although fiscal problems often drove the commercialization of air 
navigation services, commercialization was generally intended not only 
to relieve the government of a fiscal responsibility but also to free 
the ANSP from some governmental constraints. According to the 
International Civil Aviation Organization (ICAO),[Footnote 5] a 
commercialized ANSP, whether wholly or partly owned by the government 
or fully privatized, should function as an autonomous body and, 
compared with a government organization, should have greater freedom 
from the government in conducting its financial affairs and developing 
infrastructure funding. In addition, it should be self-financing, 
subject to the usual business taxes, and required to seek a return: 

on capital. According to ICAO, the government[Footnote 6] should still 
regulate the safety of the ANSP's operations,but the ANSP should be 
encouraged to be as competitive, efficient, and cost-effective as any 
other commercial business. 

In the five countries whose air navigation services we reviewed, the 
ANSP continued to provide nationwide services after commercialization 
and, with limited exceptions, remained the sole provider of air 
navigation services. Table 1 summarizes information on the size and 
scope of the five ANSPs in our review.

Each ANSP generally offers en route, approach control, and terminal (or 
aerodrome control) air traffic services. Although definitions of these 
terms may vary slightly among ANSPs, the terms generally signify the 
same broad functions. Specifically, en route services guide an aircraft 
while it is operating at cruising elevations and outside terminal 
airspace. Approach control services apply during departure-- 
immediately after the aircraft has taken off and while it is climbing 
from the origination airport--and during arrival--when the aircraft is 
descending to the destination airport toward the end of the flight. 
Terminal or aerodrome control services are provided while the aircraft 
is close to the airport from which it is arriving or departing. 
However, in some countries, the ANSP may not be the sole provider of 
approach control and terminal services.[Footnote 7] All but Germany's 
DFS also offer oceanic air navigation services.[Footnote 8] All five 
ANSPs are responsible for providing air navigation services to both 
civil and military aviation. In addition, the ANSPs may offer other air 
navigation-related services, such as meteorological, training, and 
consulting services, and charge for these services.[Footnote 9]

The five commercialized ANSPs are affiliated with one or more 
international aviation-related organizations. The governments of all 
five ANPS are members of ICAO and, therefore, all five ANSPs adhere to 
ICAO principles. All five ANSPS are also members of the Civil Air 
Navigation Services Organization (CANSO), a voluntary international 
trade organization whose mission is to represent the interests of 
commercialized ANSPs. In addition, the UK and Germany are members of 
EUROCONTROL, a European organization responsible for regulating the 
safety of air navigation, monitoring the performance of air traffic 
management systems, and developing a seamless air traffic management 
system in Europe. EUROCONTROL is mandated to develop implementing rules 
for the European Union's "Single European Sky" initiative, a 
legislative package approved by the European Parliament in January 
2004.[Footnote 10] One of these implementing rules specifies that each 
member state is to develop an independent safety and economic 
regulatory authority to oversee its ANSP. The UK established such an 
authority before commercialization, and Germany is planning to develop 
one. 

Common Characteristics of the Five Selected Commercialized ANSPs: 

The five commercialized ANSPs that we reviewed have a number of common 
characteristics: First, all focus on safely moving aircraft. Second, 
despite differences in ownership structures, all operate as businesses 
rather than as government organizations and are self-financing. Third, 
all are largely monopoly providers that are subject to some form of 
price-setting constraint achieved through economic review or procedural 
guidelines. 

The Five Commercialized ANSPs Continue to Focus on Safely Moving 
Aircraft: 

For all five commercialized ANSPs, the safe movement of aircraft 
remains the primary goal. In some instances, government policy requires 
that the ANSP consider safety in any and all decisions affecting 
operations and service. For example, according to DFS officials, German 
legislation requires DFS to observe ICAO's standards and recommended 
safety practices, as well as adhere to the objectives and policies of 
international organizations in which the German government 
participates, such as EUROCONTROL. Similarly, in Canada, legislation 
requires NAV CANADA to maintain a fixed level of safe operations. 
According to Transport Canada, the safety regulator, the Minister of 
Transport has the authority to direct NAV CANADA to maintain or 
increase levels of service in the interest of safety. Although NAV 
CANADA can alter operations in accordance with business principles, it 
must demonstrate that the changes meet the required level of safety 
through an aeronautical risk assessment. 

All five ANSPs are subject to external safety regulation. A separate 
authority conducts safety regulation and issues relevant certificates 
or licenses to air traffic controllers and technicians. In New Zealand, 
for example, the Civil Aviation Authority (CAA) is an independent 
regulatory authority that, among other things, establishes civil 
aviation safety and security standards and monitors adherence to those 
standards. CAA carries out accident and incident investigations and 
uses information from these investigations to establish an industrywide 
safety picture and develop safety initiatives ranging from educational 
campaigns to increased monitoring and regulatory action. In Australia, 
the Civil Aviation Safety Authority regulates and promotes aviation 
safety, and the Australian Transport Safety Bureau investigates 
aircraft accidents, incidents, and safety deficiencies within the 
aviation system, according to Airservices Australia. In Canada, NAV 
CANADA and the government, through Transport Canada, share 
responsibility for the safety of the national civil air navigation 
system. Under a performance-based approach to safety regulation, known 
as the relations management approach, Transport Canada, as the 
regulator, establishes the requirements in law and standards, and NAV 
CANADA, as the operator, must demonstrate compliance by measuring and 
reporting on program results. Transport Canada, among other things, 
conducts audits, adjudicates safety issues raised by stakeholders, and 
licenses air traffic controllers. 

All five selected ANSPs have also established formal safety programs. 
For example, DFS and NATS apply a systematic Safety Management 
System,[Footnote 11] in accordance with EUROCONTROL's safety 
requirements, to all of their operational activities. This system forms 
the basis for risk assessment, safety assurance, safety control, and 
safety monitoring through standards that comply with national and 
international obligations. DFS's Safety Management System was also 
certified by the German Ministry of Transport in 2004. Similarly, 
Airservices Australia employs a systemic Safety Management System that 
complies with national and international requirements. To promote 
safety, the system requires activities such as operational risk 
assessments, surveillance, audits, and incident investigations. 

Although the Degree of Government Ownership Varies, the Five 
Commercialized ANSPs Operate as Businesses, Making Their Own Decisions 
and Generating Their Own Revenue: 

The five commercialized ANSPs vary in the extent to which they are 
owned by the government--wholly, partially, or not at all. (See table 
2.) Three of these ANSPs--Airservices Australia; Airways Corporation of 
New Zealand, Ltd; and DFS--are state-owned corporations (i.e., 
companies wholly owned by the government). The UK's NATS is a public- 
private partnership (i.e., a cooperative venture between the public and 
private sectors that is designed to meet defined public needs) with the 
risks and rewards divided between both parties. The government holds 
the largest share of NATS (49 percent), and the remaining shares are 
divided among a consortium of seven UK airlines (42 percent), NATS 
staff (5 percent), and a private airport company[Footnote 12] (4 
percent). By 2006, Germany plans to change the ownership of DFS, 
selling 74.9 percent of its equity to private investors and 
reorganizing it as a public-private partnership, along the lines 
followed in the UK. NAV CANADA is a nonshare capital, private 
corporation--that is, it has "members" instead of shareholders. The 
corporation has 4 members representing government, airlines, 
noncommercial users, and the unions. These 4 members appoint 10 of the 
15 board directors: 4 are appointed by the airline industry, 3 by the 
government, 2 by employees such as air traffic controllers and 
engineers, and 1 by general and business aviation. These 10 directors 
appoint another 4 based on expertise and the chief executive officer.

[End of table]

Before commercialization, members of the two ANSPs that are not wholly 
owned by their government, NATS and NAV CANADA, "purchased" some or all 
of the ANSP assets from the government. Although the UK government 
retained the largest share of NATS, the second-largest owner, the 
consortium of seven UK airlines known as "The Airline Group," provided 
approximately $1.4 billion, according to information from the National 
Audit Office, including about $112.2 million from the group's own 
resources and the remainder from a loan taken out with a consortium led 
by four major banks.[Footnote 13] The group used this sum to acquire 
NATS and meet associated transaction costs, leaving cash assets of 
approximately $6.0 million in the business. In total, the government 
received an estimated $1.3 billion in cash proceeds from the 
transaction.[Footnote 14] NAV CANADA purchased all of the ANSP assets 
from the Canadian government. Instead of going through a formal 
competitive bidding process, it negotiated a selling price with the 
government, and purchased the air navigation system in 1996 for about 
$1.5 billion, using a $2.9 billion line of credit provided by a 
syndicate of banks at the time of the purchase. NAV CANADA uses the 
remaining funds for capital investment and as working capital, as 
required. 

The ANSPs Make and Execute Their Own Decisions, Involve Stakeholders, 
and Follow Corporate Practices: 

Each ANSP makes and carries out its own strategic, operating, and 
financial decisions. A supervisory board oversees policy making and 
operations and, when applicable, has fiduciary responsibilities to 
shareholders. The members of this board may represent key stakeholders, 
such as the airlines, employees, general aviation, and the national 
government. For example, in the UK, government appointees, the 
airlines, and BAA (the airport consortium) are represented on NATS's 
board of directors, while in Germany, DFS employees, government 
ministries, and the private sector are represented on a supervisory 
board. As in a corporation, an executive officer implements the ANSP 
board's policies and is, in turn, accountable to the board. Individual 
business units within the ANSP report to the chief executive officer 
and are directly responsible for various aspects of the ANSP's day-to- 
day operations. For example, Airservices Australia is structured around 
three market-oriented business groups--the Air Traffic Management, 
Airport Services, and Infrastructure Support Services groups. A 
Corporate Services group and a small Head Office support and lead the 
business groups. The managers of these five groups form the Executive 
Committee and work with the chief executive officer to advise the board 
as well as carry out the board's policies. 

While the supervisory board and its executive officers have decision- 
making responsibility, stakeholders--including employees, the airlines, 
general aviation operators, airports, the government, the public, and 
others--may be involved in and provide input to their ANSP through a 
variety of mechanisms. For example, DFS has developed a Customer 
Relationship Management System to organize hearings for customers and 
involve them in working groups. This approach to involving stakeholders 
is consistent with a Single European Sky directive that member states 
establish a mechanism for consulting with stakeholders. In Australia, 
the aviation community (i.e., the airports, airlines, safety 
authorities, and others) participates in Airservices' strategic 
investment decision-making process through the Australian Strategic Air 
Traffic Management Group. In Canada, NAV CANADA's stakeholders (i.e., 
associations, unions, and airports, including international and U.S. 
representatives) are involved in the NAV CANADA Advisory Committee, 
which provides a vehicle for stakeholders who are not on the board of 
directors to raise issues and concerns with NAV CANADA. 

As commercial organizations, the ANSPs follow corporate practices. Each 
ANSP has established performance measures and gathers and reports 
financial and other performance data. Each ANSP also publishes an 
annual report, which makes financial information available to the 
public to ensure transparency. Financial statements are typically 
subject to audits by independent third parties to ensure that adequate 
accounting records have been maintained, and that internal controls 
have prevented or detected any fraud and error in the accounting 
policies and estimates.[Footnote 15] In addition, the UK and Germany 
report their data to EUROCONTROL, whose Performance Review Commission 
collects data for benchmarking and publishes comparative studies of 
members' performance. 

The ANSPs Generate Revenue and Have Borrowing Authority: 

All five commercialized ANSPs rely on user charges as their primary 
source of revenue and on capital markets for additional funding. Before 
commercialization, governments funded air navigation services through 
annual appropriations. 

Since commercialization, each ANSP collects and manages its own 
revenues, charging fees for services. The air navigation service fees 
are based on ICAO's cost recovery principles, which call for recovering 
the ANSP's operating costs.[Footnote 16] Despite some variation across 
ANSPs, the fees are generally as follows: 

* The air navigation fees cover operating and capital costs associated 
with both en route and approach control services. These charges are 
based on a weight-distance formula.[Footnote 17] If applicable, ANSPs 
also levy charges for oceanic control. 

* The ANSPs may also charge for terminal-related services. However, not 
all ANSPs are the sole providers of terminal services. In the UK and 
Germany, for example, private firms may provide terminal services. 
These terminal charges are distinct from the landing fees typically 
charged by airports, which are usually weight-based. 

* The ANSPs may charge general aviation operators a flat fee for 
services or additional fees in particular circumstances, rather than 
charging the weight-distance fees typically assessed to larger air 
carriers. 

* The ANSPs may also exempt charges for some services. According to 
ICAO policies, the ANSPs may choose to recover less than the full costs 
of some services in recognition of local, regional, or national 
benefits. For example, in Canada, aircraft or flights dedicated to 
search and rescue, air ambulance operations, and firefighting services 
are all exempt from air navigation service charges. 

The five ANSPs vary in their treatment of any operating profits or 
losses. If an ANSP generates revenues from charges in excess of its 
costs (i.e., operating profits), it may rebate them to the users, lower 
the charges for the next year, pay some form of dividend to 
shareholders, or retain the revenues in reserve to protect against 
future losses. If costs exceed revenues, ANSPs use different strategies 
to meet those shortfalls. For example, NAV CANADA established a "rate 
stabilization fund," which it used to store revenues when the aviation 
industry was healthy. The fund could then be used to cover costs and 
keep rates stabilized when the industry was ailing. The fund was 
capitalized by operating profits earned before September 11, 2001, but 
depleted during the economic downturn caused by the events of September 
11 and the Severe Acute Respiratory Syndrome (SARS) outbreak of 
2003.[Footnote 18]

To pay for capital projects, the five ANSPs can either use current 
operating revenues or borrow funds. Before commercialization, the ANSPs 
relied on annual appropriations for capital projects; now, all five can 
borrow funds through access to debt financing and private capital. For 
example, NAV CANADA obtains all of its financing in the public debt 
markets. NAV CANADA has a borrowing capacity of about $2.4 billion, of 
which $1.8 billion is currently drawn.[Footnote 19] In Germany, DFS 
mainly finances its capital expenditures by drawing on a capital market 
program, which issues short-, medium-, or long-term notes (i.e., debt 
issuance and commercial paper), each amounting to approximately $546.4 
million for a total of almost $1.1 billion, to private investors in the 
market. DFS can also draw on an annual credit line of around $175.9 
million from its bank. 

The ANSPs Generate Revenues from Other Services: 

The ANSPs may also charge fees, as applicable, for other services, such 
as aeronautical information, consulting, and training. For example, a 
DFS business unit offers consulting services in air traffic system 
design and implementation, feasibility studies, operational planning, 
air traffic system evaluation, and safety management systems. In 2003, 
DFS's consulting service generated revenue of about $2.8 million. In 
the UK, NATS competes with other service providers to provide terminal 
services at UK airports. In addition, NATS, like DFS, consults and 
offers training for other ANSPs worldwide in implementing safety 
management systems, solving airspace capacity problems, and 
commercializing ANSPs. From this business unit, NATS generated profits 
of about $11.7 million in 2003 and about $14.8 million in 2004. 

Besides offering air navigation services in its own country, an ANSP 
may provide services and technology to other regions of the world to 
generate revenue. For example, Airservices Australia manages the upper 
airspace in the Solomon Islands. NAV CANADA recently signed a contract 
with NATS to install the Extended Computer Display System 
(EXCDS)[Footnote 20] in three London-area airports, Stansted, Gatwick, 
and Heathrow, as well as to provide NATS with its oceanic system. While 
NAV CANADA prefers commercial off-the-shelf products, it also invests 
in developing in-house technologies. Many of the technology products 
developed by NAV CANADA are available to outside organizations, such as 
NATS, enabling them to reduce their costs and avoid development risks. 

The Five Commercialized ANSPs Undergo Some Form of Economic Review or 
Follow Price-Setting Process Guidelines: 

Each of the five commercialized ANSPs is its country's sole provider of 
en route services and, as such, functions as a monopoly. Moreover, 
except in the UK, the ANSP is the sole provider of approach control 
services.[Footnote 21] With no alternative provider, operators cannot 
seek lower prices by changing routes and must pay whatever fees the 
ANSP charges. Since user fees constitute the ANSP's primary source of 
revenue, economic monitoring and regulation by an independent third 
party can protect users and ensure a fair pricing process. 

ICAO recognizes the need for an independent mechanism to provide 
economic regulation of air navigation services. According to ICAO, the 
objectives of economic regulation should include the following: 

* Ensure nondiscrimination in the application of charges. 

* Ensure that there is no overcharging or other anticompetitive 
practice. 

* Ensure the transparency and availability of all financial data used 
to determine the basis for charges. 

* Assess and encourage efficiency and efficacy in the operation of 
providers. 

* Establish standards for reviewing the quality and level of services. 

* Monitor and encourage investments to meet future demand. 

* Ensure user views are adequately taken into account. 

The five countries whose ANSPs we reviewed have taken different 
approaches to reviewing their ANSP's user charges and price-setting 
process, but all five ANSPs are subject to some form of economic review 
or price-setting process guidelines: 

* In Australia, the Australian Competition and Consumer Commission 
(ACCC)[Footnote 22] oversees Airservices Australia's process of setting 
user fees for air traffic services. Airservices must notify the 
commission whenever it wants to raise fees. The commission then 
evaluates Airservices' pricing proposal and decides to accept or reject 
the price change. If the commission rejects the proposed price, it can 
set a lower price. ACCC rejected one of two proposals by Airservices 
for a temporary fee increase to address the revenue losses that 
followed September 11 and the SARS outbreak, as well as the collapse of 
Australia's second largest airline. ACCC accepted Airservices' first 
proposal for a temporary fee increase for a year following the 
September 11 and SARS outbreak. However, ACCC rejected Airservices' 
second proposed fee increase. The airline industry had objected to the 
second set of proposed increases, citing a need for longer term price 
certainty. The ACCC ultimately decided that a longer term arrangement 
should be considered. ACCC directed Airservices to focus on 5-year 
pricing plans to encourage long-term planning, emphasizing that the 
robustness of the airlines should be taken into account when a price is 
set. 

* The Canadian Transportation Agency (CTA) reviews the price-setting 
process against an established set of statutory principles. Appeals may 
be made to CTA by the users as to whether NAV CANADA has observed the 
charging principles in establishing its rates.[Footnote 23] The 
charging principles do not allow NAV CANADA to make a profit and, as a 
nonshare capital corporation, surpluses are reinvested in the business 
or used to lower charges to customers. 

* Airways Corporation of New Zealand, Ltd., operates under a memorandum 
of understanding with its airline users. Under this memorandum, Airways 
uses the principle of "economic value added" (EVA) to self-regulate its 
pricing. EVA is the difference between the net operating profit after 
taxes and the cost of capital. A portion of any EVA above a certain 
level is returned to users in the form of a rebate. For example, in its 
2004 Annual Report, Airways reported its net operating profit after 
taxes as about $8.3 million. After subtracting the cost of capital 
($4.4 million), the resulting EVA was approximately $3.9 million. Of 
this amount, $1.8 million was returned to customers in the form of a 
rebate, since any profits above a certain level will ultimately be 
returned to the airlines. According to the aviation industry, the EVA 
mechanism has been key in making pricing of user fees more transparent. 

* In the UK, CAA exercises economic regulation over NATS. CAA's 
Economic Regulation Group sets price caps for 5-year periods, basing 
them generally on the retail price index[Footnote 24] and the group's 
own analyses of allowances for NATS's estimated operating and capital 
costs. 

* The German Transport Ministry reviews and approves any changes in 
user fees, but it does not independently evaluate the price-setting 
process or pricing changes. According to the Transport Ministry, 
Germany plans to create an independent economic regulatory authority by 
2006 to comply with the requirements of the Single European Sky 
initiative. 

Since Commercialization, the Five ANSPs Have Maintained Safety, 
Controlled Operating Costs, and Achieved Efficiencies: 

According to information from each of the ANSPs we reviewed, air 
navigation safety has not declined since commercialization, and all 
five ANSPs have taken steps to control costs. In addition, the ANSPs 
have improved the efficiency of their operations by implementing new 
technologies and equipment. The ANSPs maintain that some of these 
outcomes would not have been feasible in a government organization. 

Safety Performance Has Not Been Compromised Since Commercialization: 

At a minimum, safety has not eroded since commercialization, according 
to the available data from most of the ANSPs.[Footnote 25] For example, 
data from DFS show a decrease in the number of aircraft 
proximity[Footnote 26] incidents in Germany, from 23 in 1995 to 8 in 
2003, 3 of which were attributed to DFS. In the UK, the number of the 
riskiest air proximity incidents for NATS declined from 9 in 2001 to 2 
in 2003 and 1 in 2004. Similarly, data from Airways Corporation of New 
Zealand indicate a downward trend in incidents involving loss of 
separation[Footnote 27] for the years following commercialization. NAV 
CANADA's annual report for 2004 also cites a decrease in the rate of 
loss-of-separation incidents, from an average of 0.96 incidents per 
100,000 movements for 1999/2000 to an average of 0.79 incidents for 
2003/2004. Officials at Transport Canada, the safety regulator, confirm 
an overall decline in aviation incidents since commercialization. 

Additionally, stakeholders have told us they believe the air navigation 
system is as safe as it was when the government provided air navigation 
services. According to some, the separation of operating and regulatory 
functions has strengthened safety regulation and diminished any 
potential conflict of interest between promoting the financial 
interests of aviation operators and protecting safety. 

As improved technology and system upgrades have allowed individual 
controllers to handle increasing levels of air traffic, concerns have 
arisen about the potential for controllers' fatigue to compromise 
safety. Data are not available to assess this potential, but some ANSPs 
have taken steps to limit and monitor controllers' workload. For 
example, the UK's CAA has regulated the hours of civil air traffic 
controllers, and its Safety Regulation Group must be notified of any 
breach by NATS or by controllers. In New Zealand, as air traffic has 
increased, some airspace sectors have been subdivided so that 
controllers are responsible for a smaller piece of airspace. DFS, in 
cooperation with its controllers' association, has undertaken a 
comprehensive study of controllers' stress and strain, which has led to 
internal regulations on the maximum working hours allowed at individual 
sectors, according to DFS. 

The Five Commercialized ANSPs Have Taken Steps to Reduce Operating 
Costs: 

To lower their personnel costs, all five ANSPs have reduced their 
administrative staff or flattened their management organizations. For 
example, NAV CANADA closed most of its regional administrative offices 
and centralized corporate functions to its headquarters, reducing 
mostly administrative staff by 1,100 people (17 percent of the 
workforce). Airways Corporation of New Zealand also reportedly reduced 
its personnel costs by eliminating some middle management and 
administrative positions. In general, the ANSPs have not reduced their 
air traffic controller staffs. 

To lower their facility operating costs, all five ANSPs have closed, 
relocated, or consolidated facilities. For example, Airways Corporation 
of New Zealand reported consolidating four radar centers into two over 
8 years and is planning to consolidate these two radar centers into a 
single center by 2006. DFS has also integrated operations and 
consolidated facilities, moving 17 approach units from airports and 
integrating them into four air traffic control centers. DFS also 
relocated the Dusseldorf control center to the Langen control center in 
2002 (see fig. 1), a year earlier than planned, and transferred and 
consolidated its headquarters from Offenbach to Langen. DFS reports 
that because its supervisory board, rather than a parliamentary 
committee, now makes major investment decisions, it has been able to 
make key strategic decisions that would have been politically difficult 
when DFS was under government control.

[End of figure] 

In the UK, NATS reduced its net operating costs by almost $161 million 
from 2002 through 2004, in part through direct management actions, 
according to its audited financial statement. For example, it 
consolidated two operations into one at a new air navigation services 
center, called the Swanwick Center. According to NATS, after placing 
this new center in service, it reduced its staff costs by nearly $20.1 
million and its costs for services and materials by about $18.5 million 
between 2002 and 2003. Between 2003 and 2004, NATS reported, it reduced 
its operating costs for air traffic services by another $21.4 million 
through cost control measures. 

The Five ANSPs Said They Have Improved Efficiency through 
Modernization: 

All five ANSPs said they have improved productivity through 
modernization--that is, through investments in upgrading or replacing 
air navigation facilities and equipment. For example, Airservices 
Australia reported increases in controllers' productivity following the 
introduction of the Australian Advanced Air Traffic System (TAAATS) 
(see fig. 2). This system replaced conventional radar screens with more 
advanced computer screens that display data from a range of sources, 
including ground-based surveillance equipment and satellite-linked 
navigational equipment on aircraft, among others. TAAATS replaced 
handwritten, paper flight progress strips with screen-based information 
that is updated automatically. DFS is also eliminating systems that 
depend on paper strips and expects productivity gains and cost savings 
to follow. In New Zealand, according to the union that represents air 
traffic controllers, individual controllers are now able to handle much 
more flight activity because of improved technology. 

Figure 2: The Australian Advanced Air Traffic System: 

[See PDF for image] 

[End of figure] 

Besides improving productivity, modernization--together with airspace 
redesign[Footnote 28]--has produced operational efficiencies, including 
fewer and shorter delays, according to the ANSPs. NATS, for example, 
reduced its average delay per flight from 2.7 minutes in 2002 to 0.74 
minutes in calendar year 2003, while handling almost 2.1 million 
flights. 

Access to Cash Flow and Borrowed Funds Has Facilitated Modernization: 

Commercialization has allowed the ANSPs to implement modernization 
projects more efficiently. Formerly, the uncertainty associated with 
the annual appropriations from national governments made it difficult 
to plan over multiple years. According to the ANSPs, access to cash 
flow and borrowed funds has allowed them to plan and execute projects 
more efficiently and has improved their ability to deliver projects on 
time, within budget, and to specification. For example, Airways 
Corporation of New Zealand deployed its new oceanic system, FANS1, in 
less than a year. The management of NAV CANADA estimates that it is 
producing new technology faster than the government once did and at 
half the cost. 

Some of the commercialized ANSPs maintain that they have achieved the 
benefits of modernization faster and at less cost by purchasing 
commercially available systems and upgrades or by modifying off-the- 
shelf technologies to meet their needs, rather than developing their 
own systems from the ground up. NATS purchased its oceanic system and 
automated tower/terminal control system from NAV CANADA. To achieve 
further purchasing efficiencies, some commercialized European ANSPs 
have developed an alliance to procure systems. For instance, Germany 
has developed a strategic alliance with Switzerland and the Netherlands 
for the joint procurement of a new radar system. 

Focus on Cost Control and Operational Efficiency Has Affected User 
Charges: 

Through their cost control initiatives and modernization efforts, some 
of the ANSPs have been able to lower their unit costs and, in turn, 
lower their charges to major commercial airlines, which pay the largest 
proportion of user fees and therefore are the primary users served by 
the ANSPs. Airservices Australia, for example, reported lower unit 
costs resulting from the increases in controllers' productivity that 
followed the introduction of TAAATS. NAV CANADA estimates that it is 
saving the airlines approximately $80.3 million annually in reduced 
aircraft operating costs. According to NAV CANADA, the airlines are now 
paying 20 percent less in user fees than they formerly paid in ticket 
taxes when the government provided air navigation services.[Footnote 
29] In Germany, Lufthansa stated that except in business years 2001 
through 2003, the airline paid less in user fees than it paid during 
the initial commercialization of Germany's air navigation service in 
1993. According to Airways Corporation of New Zealand, it reduced en 
route charges by 22 percent in 1995 and by another 13 percent since 
1997, resulting in an overall reduction of more than 30 percent. 

For general aviation operators, however, commercialization has 
sometimes meant an increase in fees. Before commercialization, many 
only paid taxes on fuel. Some countries, such as Canada and New 
Zealand, have tried to make the fees affordable for small operators by 
charging a flat fee. NAV CANADA, for instance, charges general aviation 
operators a flat annual fee of $58.[Footnote 30] According to the 
Aircraft Owners and Pilots Association-New Zealand, Airways Corporation 
of New Zealand charges general aviation operators a fee of $68 for 50 
landings. In addition, Airways eliminated the en route charge for light 
aircraft. 

Some governments have provided for air navigation services at small, 
remote general aviation and regional airports, viewing such services as 
a public good. Australia, for instance, subsidizes service to some 
regional areas under the Location-Specific Tower Subsidy Program and, 
according to Transport Canada, NAV CANADA is legislatively required to 
maintain service to remote locations in the northern region. In 
addition, NAV CANADA charges the same price for services to remote 
locations as for services to the rest of the country. The price is 
based on a formula that considers weight and distance. 

Lessons Learned about the Commercialization of Air Navigation Services: 

We have derived a number of lessons from our research on the 
commercialization of air navigation services in the five countries we 
selected. The following paragraphs summarize these lessons. 

The Commercialized ANSPs Must Be Prepared to Mitigate the Effects of an 
Industry Downturn: 

Because commercialized ANSPs rely primarily on user fees to cover their 
costs, an industry downturn presents a fundamental financial risk for 
such ANSPs that they must be prepared to mitigate, whether through a 
reserve fund, cost-cutting measures, user fee increases, additional 
borrowing, restructuring, or some combination of these or other options 
that will be sufficient to offset the decline in air traffic and the 
concomitant decline in revenue. The industry downturn that began in 
about 2000 and intensified after the events of September 11, 2001, and 
the SARS outbreak of 2003 brought this lesson home to at least four of 
the five commercialized ANSPs we selected for review. After 
commercialization and before the downturn, these four--Airservices, 
DFS, NATS, and NAV CANADA--had been able to cover their costs through 
user fees and borrowing. However, during the downturn, they had to take 
additional steps to address the revenue losses. NATS, with the greatest 
debt load, was the most vulnerable, but even NAV CANADA, with a 
multimillion-dollar contingency fund, eventually had to take 
extraordinary measures. 

Besides being burdened with debt, NATS was vulnerable to the industry 
downturns because nearly all of its costs (95 percent) were fixed, 
limiting its ability to cut costs, and its revenues depended heavily on 
North American air traffic. Specifically, North American flights 
accounted for 14 percent of its flights and 44 percent of its revenues. 
When transatlantic traffic declined after September 11, NATS's revenues 
declined 15 percent. To avoid insolvency, NATS first obtained an 
estimated $104.2 million in short-term loan credit from its lending 
banks and then refinanced, bringing in a new equity partner (BAA, 
plc).[Footnote 31] However, the combination of lost business and 
increased debt threatened NATS with insolvency in early 2002, leading 
it to implement operational cost savings, obtain a temporary loan 
credit, refinance its debts, renegotiate prices for users through a new 
regulatory structure, and obtain additional funds from the government 
and private shareholders. 

Under its new regulatory structure, NATS now has a system in place to 
mitigate the effects of an industry downturn through automatic price 
increases that are triggered by reductions in air traffic. These price 
increases go into effect when traffic falls below a benchmark level, 
limiting NATS's revenue loss to 50 percent of the revenue that would 
have been generated if the benchmark level of traffic had been reached. 
If traffic falls below this 50 percent benchmark, as it might in a 
severe crisis, NATS's revenue loss is limited to 20 percent of the 
projected revenue. In effect, this automatic trigger mechanism spreads 
the risk of traffic downturns between NATS and its airline customers. 
Without this trigger, the prices set by CAA, the economic regulatory 
body, would remain fixed until the next regularly scheduled review when 
prices may be adjusted, upward or downward, and benchmark levels set. 

In Germany, DFS also lost revenue during the industry downturn, but to 
a lesser degree. DFS reported a loss of more than $36.4 million in 
2001, when air traffic declined by 0.9 percent over the previous year. 
In 2002, it sustained a loss of more than $23.2 million, when air 
traffic levels fell 2.9 percent below 2001 levels. To address these 
deficits, DFS modified investments, canceled projects, and ultimately 
raised fees, thereby increasing financial pressures on the airlines. 
However, when air traffic increased again in 2003, DFS recorded an 
operating profit of more than $87.4 million and reduced its 2005 fees 
for en route services by 19.5 percent and for approach control services 
by 28 percent. DFS has begun to consider the benefits of a reserve 
fund, but German legislation governing air navigation service charges 
must be changed before DFS can develop such a reserve. 

Before September 11, NAV CANADA banked up to $66.3 million in its rate 
stabilization fund to protect against future losses. However, with the 
industry downturn, this fund was quickly exhausted and, after the SARS 
outbreak in 2003, the fund reached a cumulative deficit of about $96.9 
million. To maintain operations, NAV CANADA cut costs and raised its 
service fees, consulting with users as required. By the end of 2004, it 
reduced the deficit to approximately $26.0 million, according to its 
2004 annual report. However, as aviation industry representatives have 
noted, the fee increases had the inadvertent effect of disrupting the 
business cycles of air carriers, which faced the same difficult 
economic circumstances. Moreover, because NAV CANADA's price-setting 
process is limited only by statutory charging principles, NAV CANADA 
was able to raise its fees unilaterally, without having to negotiate 
increases with representatives of the airlines or other interests. Its 
board approved the fee increases to balance revenues and expenses as 
required by legislation. The CTA rejected an appeal of the increases 
brought by certain operators. 

Involving Stakeholders in Modernization Efforts Can Help Ensure 
Mutually Beneficial Results: 

According to the ANSPs, involving stakeholders in efforts to design, 
acquire, and deploy new technologies can be beneficial. For example, 
Airways Corporation of New Zealand noted that its investment decisions 
are very much driven by customers' needs. Airways said it consults 
closely with the airlines before deciding to acquire new systems and to 
implement technology upgrades. According to Airways, if the airlines 
say they do not want to make a particular investment and the investment 
adds no value for the customer, Airways will not spend the money. For 
example, the airlines have reported that they are not currently 
interested in Automatic Dependent Surveillance-Broadcast,[Footnote 32] 
so Airways has no immediate plans to invest in the technology. DFS has 
also reported that consulting with its customers before investing in 
any modernization efforts has been beneficial. According to DFS, before 
commercialization, the German government did not consult with users and 
other stakeholders when it acquired and deployed new air navigation 
technologies. 

Once an initial investment decision has been made, ANSPs have further 
reported, it is beneficial to involve stakeholders throughout the 
design and acquisition process. For example, Airservices Australia 
reported that, since commercialization, air traffic controllers play a 
much larger role in the acquisitions process and have come to 
understand the linkage between service delivery costs and the costs of 
new equipment. Similarly, Airways Corporation of New Zealand noted that 
it has found it essential to involve the same controllers throughout 
the design process to ensure consistency in requirements and to 
maintain a thorough understanding of the project's ongoing 
specifications. In Airways' experience, it is essential for 
controllers, manufacturers, and the ANSP to reach agreement in order to 
establish realistic expectations for system design from the very 
beginning. 

Steps May Be Needed to Balance Business and Small Community Interests: 

In some instances, an ANSP's need to recover its costs may be at odds 
with a small or remote community's need for scheduled air service. 
Providing air navigation services for such communities may not be 
commercially viable because it typically generates less revenue than 
providing services for larger communities. Even though the minimum cost 
of an air navigation service is the same, regardless of the location, 
the cost per plane is often higher at small or remote locations because 
the cost of the service is spread among fewer operators, usually with 
smaller planes. 

In the past and in some countries today, the ANSPs charged the same fee 
for air navigation services at every airport, regardless of its size or 
location. Under this arrangement, called network pricing, services at 
heavily used airports subsidize services at small or remote airports. 
However, two of our five ANSPs, Airservices Australia and Airways 
Corporation of New Zealand, have adopted an alternative pricing scheme, 
called location-specific pricing, under which the fee for some service 
matches the cost of providing that service to a specific 
location.[Footnote 33] Once this scheme is fully implemented, formerly 
subsidized air navigation services to small or remote locations may 
likely cost more. If an airline decides that it does not want to pay 
the increased fees, it may discontinue service to the location. 
However, air service may be the only means of public transportation to 
some small or remote locations. Continuing to provide air navigation 
services to small or remote locations may require special efforts to 
balance community needs and business interests. 

Airservices Australia has reported that it plans to phase in location- 
specific pricing to ease the transition from network pricing. According 
to Airservices, it will increase charges over the next 5 years at 
general aviation and regional airports and the increased charges have 
been approved by the regulator. Although the increases will be gradual, 
the plan has raised concerns about further price increases and any 
future need to close or reduce services at these locations. Some fear 
that needed air services to remote bush locations will be lost, while 
others fear that secondary services, such as flight school training, 
which are typically provided at smaller airports, will be affected. 

The impact of location-specific pricing on remote communities and small 
operators is difficult to predict. Costs may go up, but charges may not 
necessarily be prohibitive. When legislation calls for service to 
remote communities, an ANSP may ultimately be forced to take a 
financial loss if it is not able to fully recover its costs. 
Airservices Australia is seeking to control costs at some locations by 
deploying new lower cost technologies to serve remote communities. For 
example, Airservices Australia is planning to install Automatic 
Dependent Surveillance-Broadcast ground stations, which will allow air 
traffic surveillance services over remote regions of Australia where no 
surveillance currently exists and where the introduction of radar would 
not be cost-effective. 

Appropriately Assessing the Value of Assets Is Essential for Sound 
Pricing and Cost Accounting: 

To protect taxpayers' interests, Canada and the UK needed to have an 
appropriate valuation of their facilities and equipment before wholly 
or partially selling these assets to their newly established ANSP. 
According to its Office of the Auditor General (OAG), Canada did not 
properly value its ANSP assets and infrastructures. The approximately 
$1.5 billion value that the government negotiated with NAV CANADA in 
1996 fell short of the $2.3 billion to $2.4 billion estimate developed 
in 1995 by a third party. NAV CANADA reported, however, that both it 
and Transport Canada disagreed with the OAG's estimate and its 
underlying assumptions. In a study of the NATS reorganization, the 
National Audit Office found that the UK government raised some $1.3 
billion from the sale of the ANSP to a consortium of seven UK-based 
airlines. However, these proceeds were realized by increasing the level 
of NATS's bank debt. As a result of this debt, NATS was extremely 
vulnerable to the decline in air traffic after September 11. DFS is 
currently undergoing a valuation of its key assets in preparation for 
selling 74.9 percent of its equity to private investors in a formal 
competitive bidding process. 

Maintaining Staff Levels and Expertise during Commercialization Can 
Prevent Disruptions in Regulatory Functions: 

Some countries that commercialized their ANSP had difficulty retaining 
a sufficient number of staff to carry out safety regulation. For 
example, in Canada, many of the safety staff moved to the newly 
established NAV CANADA after commercialization, leaving the government 
regulator, Transport Canada, with insufficient staff to carry out 
timely safety inspections during the first 6 months after 
commercialization. Germany faces a similar challenge as the government 
prepares to develop a safety regulatory authority in accordance with 
the Single European Sky initiative by the end of this year. According 
to the Transport Ministry, it may be difficult for the government to 
recruit safety staff at a civil service salary when the private sector 
is paying higher salaries for safety inspectors to develop safety 
standards and procedures. CAA managers with responsibilities for 
regulating the safety of NATS's operations also raised concerns about 
recruiting staff. According to these officials, regulators need the 
highly skilled expertise of air traffic controllers. However, the high 
salaries of air traffic controllers of the ANSPs make it difficult to 
recruit them for regulatory positions. 

Developing Baseline Measures before Commercialization Can Enhance 
Performance Measurement: 

Obtaining baseline measures before commercializing a country's air 
navigation services will allow the government and others to assess the 
new ANSP's performance in the areas of safety, cost, and efficiency. 
Some of the countries whose ANSPs we reviewed did not collect baseline 
data or measure performance as extensively as the commercialized ANSPs 
have since done. As businesses, commercialized ANSPs must assess the 
performance they are making toward their goals to access private 
funding and, therefore, they need extensive performance data. However, 
lack of baseline measures before commercialization makes it difficult 
to gauge its development before and after commercialization. For 
instance, the Canadian OAG considered the assets of NAV CANADA to be 
undervalued, due to the absence of good financial information before 
commercialization. In addition, international organizations that 
support commercialized ANSPs have emphasized the importance of 
developing performance measures and benchmarks. ICAO, for example, 
stresses the importance of having transparent financial data available 
for economic oversight, and CANSO and EUROCONTROL are working to 
standardize performance measures and compare ANSPs across dimensions 
such as safety, cost, and efficiency. 

We are sending copies of this report to interested congressional 
committees; the Secretary of Transportation; the Administrator, FAA;

Appendix I: Scope and Methodology: 

We developed a descriptive analysis of selected foreign countries' 
commercialized, performance-based air navigation services providers 
(ANSP) by reviewing the characteristics and performance of five such 
organizations, which we selected as illustrative of similarities and 
differences in ownership, length of experience with commercialization, 
and size and scope of operations. We then analyzed the information we 
had gathered to identify lessons learned about the commercialization of 
air navigation services. Our review included site visits, agency 
interviews, and analyses of documents provided during our site visits 
and obtained through our own research. The ANSPs--Australia's 
Airservices Australia; Canada's NAV CANADA; Germany's Deutsche 
Flugsicherung GmbH (DFS); New Zealand's Airways Corporation of New 
Zealand, Ltd; and the United Kingdom's (UK) National Air Traffic 
Services, Ltd. (NATS)--were commercialized between 1987 and 2001 and 
have been operating since then as performance-based organizations. 
Because we selected these ANSPs to illustrate specific characteristics, 
our results cannot be generalized to all commercialized ANSPs. 

To describe common characteristics of commercialized air navigation 
services in the selected countries, we conducted a computer search on 
key elements of each ANSP and conducted interviews in each country. We 
collected information on the size and scope of air traffic (e.g., 
number of aircraft movements and number of air traffic controllers); 
the ownership, management, and funding structures of each country's 
ANSP; and institutional mechanisms for stakeholder input. We 
interviewed government officials, ANSP executives and representatives, 
union officials, and representatives of aviation stakeholders in each 
country to synthesize information on how air navigation services were 
delivered before commercialization and the key elements and 
characteristics of commercialized ANSPs. 

To describe how the safety, cost, and efficiency of foreign air 
navigation services have changed since commercialization, we conducted 
interviews and reviewed documents obtained during our site visits. We 
also gathered information through our own computer research. We 
interviewed government officials, ANSP executives and representatives, 
national audit officials, union officials, and representatives of 
aviation stakeholders to obtain their views on how safety, cost, and 
efficiency have changed since air navigation services were 
commercialized. In addition, we interviewed officials from the 
International Civil Aviation Organization (ICAO), the Civil Air 
Navigation Services Organization (CANSO), EUROCONTROL, and the European 
Commission to obtain their perspectives on these issues. Finally, 
through our computer research and analysis of documents obtained during 
our site visits, we obtained additional information on the performance 
of each ANSP, including its safety, costs, and efficiencies, since 
commercialization. 

To identify lessons learned about the commercialization of air 
navigation services, we conducted interviews and reviewed literature on 
commercializing air navigation services and implementing performance- 
based air traffic organizations. In each country, we interviewed 
government officials, ANSP executives and representatives, union 
officials, and representatives of aviation stakeholders, asking them 
about the lessons they had derived from commercialization. We also 
reviewed literature from academics and experts on commercializing air 
navigation services and synthesized information from our interviews 
with information from the literature to arrive at some general lessons 
on the commercialization of the five air navigation service providers 
we reviewed. 

Unless otherwise noted, we converted the local currencies of each 
country into U.S. dollars using the Organization for Economic 
Cooperation and Development's purchasing power parity historical series 
for each country in the relevant years for the currency. We adjusted 
for inflation using the Gross Domestic Product price index of the 
Congressional Budget Office's economic projection for 2005 to obtain 
the estimated value of each country's currency in 2005 U.S. dollars. 

We did not compare performance before and after commercialization or 
across countries. Such comparisons are generally not feasible because 
data for assessing performance are typically unavailable for the time 
before commercialization, or the measures have changed in the years 
following commercialization. Furthermore, comparisons between or among 
ANSPs are difficult because each ANSP may define its measures of cost, 
safety, and performance differently. 

We determined from our review of the independently audited financial 
reports of each ANSP that the financial data we obtained and used for 
our engagement were sufficiently reliable for our purposes. An 
independent audit was conducted on the annual financial reports of each 
of the five ANSPs in accordance with the applicable country's 
accounting standards and practices. The independent auditors for each 
ANSP found that the annual financial statements were unqualified and 
fairly presented, in all material respects, the financial condition and 
position of the ANSP. 

To identify any changes in safety since commercialization, we collected 
and analyzed information provided by each ANSP and by its independent 
safety regulator. We interviewed officials from these regulators, and 
we relied on safety data from the ANSPs and their audited annual 
financial reports, which had been independently reviewed and evaluated. 
To assess the reliability of these data, we (1) interviewed the 
officials from each ANSP and its independent safety regulatory 
authority who were responsible for compiling these data and (2) 
corroborated the data through comparison with other sources of 
information. We determined that the data from each country were 
sufficiently reliable to identify any major changes in safety since 
each ANSP was commercialized.

FOOTNOTES

[1] According to the International Civil Aviation Organization, 
"commercialization" is the ability of an organization to operate like a 
commercial business. In discussions about air navigation services, the 
term is often used interchangeably with other terms, including 
restructuring, privatization, outsourcing, and corporatization. For 
this report, we use the term "commercialization."

[2] A performance-based organization (PBO) is a discrete management 
unit with strong incentives to manage for results. In the 1990s, 
Congress recognized the need to restructure federal agencies and to 
hold them accountable for achieving program results. To this end, 
Congress legislated the establishment of PBOs, modeled after the United 
Kingdom's executive agencies. As designed in statute, PBOs were to 
commit to clear management objectives and specific targets for improved 
performance. These clearly defined performance goals, coupled with 
direct ties between the achievement of the goals and the pay and tenure 
of the head of the PBO and other senior managers, were intended to lead 
to improved performance. 

[3] Because we selected the five ANSPs in our sample to illustrate 
similarities and differences in specific characteristics, our sample is 
a nonprobability sample, and the results from such a sample cannot be 
used to make inferences about the ANSPs we did not review. 

[4] For additional information on performance-based organizations, see

15, 1997). 

[5] ICAO is an advisory organization affiliated with the United Nations 
that aims to promote the establishment of international civil aviation 
standards and recommended practices and procedures. 

[6] In the UK and Australia, safety and economic regulators are 
"statutorily independent within the government." A statutory authority 
is a public sector entity, established by legislation, which has the 
legal status of a corporate body. The reference to "independent" 
reflects an intended degree of independence from the Minister, whereby 
the director of the entity is responsible for its day-to-day operations 
but is accountable for its performance to the Minister. 

[7] Although technical definitions may vary slightly among ANSPs, these 
services broadly correspond to the services provided in U.S. air 
traffic centers, approach control centers, and towers. 

[8] Oceanic services are analogous to en route services, except that 
the aircraft is flying over the ocean, where fewer communication, 
navigation, and surveillance capabilities are available than over land. 

[9] NATS and NAV CANADA include charges for meteorological services in 
their basic service charges. 

[10] This initiative consists of four regulations that address (1) the 
framework for the creation of a single European sky, (2) the provision 
of air navigation services in the single European sky, (3) the 
organization and use of the airspace in the single European sky, and 
(4) the interoperability of the European Air Traffic Management 
network. 

[11] The Safety Management System is a systematic and explicit approach 
defining the activities by which an ANSP undertakes safety management 
to achieve acceptable or tolerable safety levels. It is a system to 
ensure that the ANSP has identified, assessed, and satisfactorily 
mitigated all safety risks, including establishing procedures for 
reporting and assessing safety occurrences in air traffic control and 
for assessing and mitigating risks. 

[12] This private company, BAA, plc., owns 7 UK airports, including 
London's Heathrow, Gatwick, and Stansted, and has interests at 13 
airports overseas. 

[13] Unless otherwise noted, all financial amounts have been converted 
to U.S. dollars from each country's local currency and adjusted for 
inflation. 

[14] National Audit Office, The Public Private Partnership for National 
Air Traffic Services Ltd., report by the Comptroller and Auditor 
General, HC 1096, Session 2001-2002, July 24, 2002. 

[15] As a publicly traded corporation, NAV CANADA is subject to the 
equivalent in Canada of the U.S. Sarbanes-Oxley Act, which requires 
independent auditors to attest to and report on internal control of the 
organization. 

[16] Fees for the European ANSPs also include a contribution to cover 
the expenses of EUROCONTROL. 

[17] The standard weight-distance formula is a single charge per flight 
for en route services based on the distance flown by the aircraft 
within a defined area and the aircraft's weight. This formula is based 
on ICAO's policies on charges for air navigation services. 

[18] Concerns about the in-flight transmission of SARS, a highly 
contagious respiratory disease that appears to be transmitted by close 
personal contact, affected passenger traffic on international flights 
to and from Asia, compounding the economic downturn in the aviation 
industry that began in 2000. 

[19] The amount here does not include adjustments for inflation because 
it refers to the current 2005 year. The foreign exchange rate as of 
June 17, 2005 (1 U.S. dollar = 1.23 Canadian dollars), was used to 
convert to U.S. dollars. 

[20] EXCDS is an advanced flight data processing system developed by 
NAV CANADA that allows controllers to manage electronic flight data 
online using mouse-based or touch-sensitive display screens. 

[21] In the UK, terminal services are open to competition. NATS 
competed for and won the opportunity to provide terminal services for 
14 UK airports, including its largest airports, Heathrow and Gatwick. 

[22] This independent Commonwealth authority monitors primarily 
monopolistic public and private service industries, including 
Airservices Australia. 

[23] NAV CANADA's board of directors, which includes air carrier 
representatives, is the main venue for the industry to express any 
grievances over pricing issues after a required open and transparent 
consultation process. However, according to Air Canada, its input on 
the board is limited and, because the public has comparable 
representation on the board, the public--with three government and two 
employee representatives--and the industry--with four representatives-
-cancel out each other's input. As previously noted, when NAV CANADA 
raised prices after its rate stabilization fund was exhausted during 
the economic downturn, aviation industry representatives argued that 
this move further disrupted their business cycles during a time of 
financial strain. 

[24] The retail price index is the average measure of change in the 
prices of goods and services bought for consumption by the vast 
majority of households in the UK. 

[25] Since aviation accidents are rare and may be attributable to 
causes outside their control, ANSPs gather data on incidents that could 
pose hazards and may be within their control. Rates for these incidents 
are proxy measures for safety. 

[26] An aircraft proximity incident occurs when the pilot or air 
traffic controller deems the safety of the aircraft involved to be 
endangered, whether because of speed or nonadherence to minimal 
standards for separation between aircraft. 

[27] A loss of separation is an occurrence or operation that results in 
less than the prescribed separation between an aircraft and another 
aircraft; a land barrier, such as high terrain; or a vehicle on the 
runways of airports. 

[28] Airspace redesign is a reconfiguration of the established routes 
that aircraft fly to maintain standard separation from other aircraft 
when arriving at or departing from airports. 

[29] While Australia, Canada, and New Zealand collect both en route and 
terminal fees themselves, Germany and the UK collect terminal fees 
themselves and receive en route fees collected for them by EUROCONTROL. 

[30] This amount does not include adjustments for inflation because the 
fee is established for the current 2005 year. The foreign exchange rate 
as of June 17, 2005 (1 U.S. dollar = 1.23 Canadian dollars), was used 
to convert to U.S. dollars. 

[31] Total new investment made in NATS as part of the refinancing 
arrangement was approximately $225.7 million--about $112.8 million from 
BAA, plc, matched by an additional $112.8 million from the UK's 
Department for Transport. 

[32] Automatic Dependent Surveillance-Broadcast is a system that allows 
pilots and air traffic controllers to "see" the location of nearby 
aircraft and engage in collaborative decision making. It broadcasts 
aircraft position data from an onboard navigation system, such as the 
global navigation satellite system. 

[33] NATS has not implemented location-specific pricing. However, 
airport services are provided through a competitive process in the UK, 
and the prices for these services may therefore vary by location.
