Why GAO Did This Study: 

Congress’s formation of the Air Traffic Organization (ATO) and the 
Joint Planning and Development Office (JPDO), both within the Federal 
Aviation Administration (FAA), represent the latest efforts to address 
the monumental challenges of modernizing the national airspace system 
(NAS) during the first quarter of the twenty-first century. For more 
than two decades, FAA has been working to modernize the air traffic 
control (ATC) system, but projects have repeatedly missed cost, 
schedule, and performance targets. Consequently, ATC modernization has 
been on GAO’s list of high-risk federal programs since 1995. 
 
The ATO’s focus is on a rolling 10-year outlook to operate and 
modernize the NAS. By contrast, the JPDO’s vision is longer term, 
focused on coordinating the research efforts of diverse federal 
agencies to achieve a common goal of meeting potential air traffic 
demands in 2025.

This statement discusses (1) GAO’s assessment of the ATO’s efforts to 
date in addressing some of the key challenges for the ATC modernization 
program and (2) challenges that lie ahead for the ATO and options that 
it could consider in addressing the needs of the NAS over the next 
decade, as well as longer-term needs defined by the JPDO.

What GAO Found: 

The ATO is taking a number of positive steps to address the legacy 
cost, schedule, and performance problems that have affected the ATC 
modernization program for the past two decades. For example, the ATO is 
beginning to involve stakeholders early and throughout a system’s 
development; has demonstrated a willingness to cut major acquisitions 
that are not meeting their goals, even after investing significant 
resources; and has improved its management of information technology. 
However, the ATO does not use a knowledge-based approach to 
acquisitions, characteristic of best commercial and federal practices, 
which would help avoid cost, schedule, and performance problems. 
Additionally, the ATO has used a process improvement model in several 
software-intensive acquisitions. However, because the ATO has not 
mandated use of the model in all such acquisitions, it risks taking a 
major step backwards in its capabilities for ATC systems and software. 
Finally, the ATO is taking steps to change the culture of its component 
organizations by, for example, replacing a personality-driven culture 
with one that is more sustainable and stable. Continued management 
attention in this area will be important to the organization’s success.

The ATO faces the challenges of (1) modernizing and expanding NAS 
capacity to accommodate an expected 25-percent increase in the volume 
of air traffic over the next 10 years, (2) hiring thousands of air 
traffic controllers to replace those expected to retire over the next 
decade, (3) working with the new JPDO to coordinate the research 
efforts of diverse federal agencies to transform the NAS to meet 
potential air travel needs of 2025, and (4) addressing aging 
infrastructure. To fund its major system acquisitions through fiscal 
year 2009 while remaining within projected budget targets, the ATO has 
substantially reduced funding for other areas. However, the ATO does 
not provide administration and congressional decisionmakers with 
information about the impact of the reduced funding on NAS 
modernization. To deal with these challenges, some aviation experts 
suggested options that the ATO could consider, including contracting 
out more services and incurring debt to obtain multiyear funding for 
capital investments (an option requiring legislative change). Our work 
and some experts also suggest clarifying budget submissions to show 
decisionmakers how constrained budgets affect NAS modernization and how 
the ATO is working to live within its means.

Mr. Chairman and Members of the Subcommittee: 

We appreciate the opportunity to participate in today's hearing to 
discuss the implementation of the Federal Aviation Administration's 
(FAA) Air Traffic Organization (ATO) and the new Joint Planning and 
Development Office (JPDO). Both organizations represent the latest 
efforts of Congress and FAA to address the monumental challenges of 
transforming the national airspace system (NAS) during the first 
quarter of the twenty-first century. As key organizations for 
determining how to safely accommodate projected increases in air 
traffic demand, the ATO and JPDO are distinct yet complementary. The 
ATO's focus is on a rolling 10-year outlook to operate and modernize 
the NAS. By contrast, the JPDO's focus is longer term--determining how 
the NAS will meet possible air traffic demands in 2025. 

As brief background: in 1981, over two decades ago, FAA began what it 
initially proposed as a 10-year program to replace and upgrade the 
NAS's facilities and equipment. However, systemic management problems 
associated with ATC system acquisitions and organizational culture 
resulted in cost growth, schedule slippages, and performance 
shortfalls, leading us to classify FAA's ATC modernization program as 
high risk in 1995.[Footnote 1] In 2000, the administration issued an 
executive order that called for a performance-based air traffic 
organization to, among other things, improve the provision of air 
traffic services and accelerate modernization efforts, and Congress 
passed legislation that established an oversight body and a chief 
operating officer. FAA hired a chief operating officer in 2003 and in 
February 2004, formed the ATO, merging its former acquisitions[Footnote 
2] and air traffic operations offices, to manage FAA's air traffic 
control investments and operations. Congress also directed the 
Secretary of Transportation to establish the JPDO to develop a "next 
generation" transportation plan to meet air traffic demands by 2025. 
Located within FAA and reporting to the FAA Administrator, the JPDO has 
responsibility for coordinating the research efforts of several diverse 
federal agencies to support the goals of the next-generation plan. 

My statement today will focus on two key questions: First, what is 
GAO's assessment of the ATO's efforts to date in addressing some of the 
key challenges for the ATC modernization program? Second, what 
challenges lie ahead for the ATO, and what options could it consider in 
addressing the needs of the NAS over the next decade, as well as the 
longer-term needs defined by the JPDO? My statement is based on 
recently completed and ongoing studies for this committee and for the 
House Committee on Government Reform. We obtained information from FAA 
officials, an international panel of aviation experts, and relevant 
stakeholders on the ATO's prospects for addressing the systemic 
management problems on which we and others have reported. (See the list 
of related products at the end of this statement). Later this year, we 
expect to issue a detailed report that will address these and other 
related issues. We also obtained information and perspectives from the 
JPDO and other knowledgeable sources on its mission and plans for 
achieving that mission. We performed our work in accordance with 
generally accepted government auditing standards. 

In summary: 

* The ATO is taking a number of positive steps to address legacy 
challenges in system acquisitions and organizational culture that have 
affected the ATC modernization program for the past two decades. Our 
work indicates that four interrelated factors have contributed to the 
legacy challenges in meeting system acquisitions' cost, schedule, and 
performance targets: (1) funding acquisitions at lower levels than 
called for in agency planning documents, (2) adding requirements and/or 
unplanned work, (3) underestimating the complexity of software 
development, and (4) not sufficiently involving stakeholders throughout 
system development. Among the positive steps it is taking, the ATO is 
beginning to include stakeholders in all phases of system development, 
so that they can provide input in response to technical or financial 
developments. The ATO has also demonstrated a willingness to cut some 
major acquisitions that are not meeting their goals, even after 
investment of significant resources. And it has improved its management 
of information technology investments and software-intensive 
acquisitions. However, the ATO does not use a knowledge-based approach 
to system acquisitions, characteristic of best commercial practices for 
managing commercial and Department of Defense (DOD) product 
developments, which would help avoid cost, schedule, and performance 
problems. Additionally, because the ATO has not mandated use of a 
process improvement model for all software-intensive acquisitions, it 
risks taking a major step backwards in its capabilities for ATC systems 
and software. Finally, the ATO has recognized the fundamental 
importance of changing its organizational culture; it has been working 
on altering its leadership model and replacing a personality-driven 
culture--one that changes as leadership changes--with one that is 
sustainable and stable. Continued improvement and management attention 
will be crucial if the organization's efforts are to succeed. 

* The ATO's key challenges include modernizing and increasing NAS 
capacity to accommodate a 25-percent increase in air traffic operations 
by 2015, hiring thousands of air traffic controllers to replace those 
expected to retire in the next decade, working with the new JPDO to 
ensure that research programs led by diverse agencies support national 
goals, and repairing or replacing facilities believed to be beyond 
their useful lives. The ATO will be further challenged to accomplish 
these tasks while remaining within the administration's future budget 
targets, which are lower than those of recent years. To fund its major 
system acquisitions while remaining within the budget targets, the ATO 
has eliminated planned funding to start new projects and substantially 
reduced planned funding for other areas. However, when forwarding its 
budget submission for administration and congressional review, the ATO 
provides no detail on the impact of the planned funding reductions on 
ATC or NAS modernization. Aviation experts and our work have identified 
options for the ATO to increase its chances of success. First, some 
aviation experts proposed that the ATO evaluate its experience in 
contracting out flight service stations and, if positive, consider 
contracting out other services. Second, some experts suggested that the 
ATO be allowed to incur debt so that it could obtain multiyear funding 
for capital investments, an option that would require a legislative 
change. While we have consistently maintained that Congress should 
control new funding sources through the budget and appropriations 
processes, these experts believed that giving the ATO access to 
multiyear funds for capital investments would increase its flexibility, 
thereby allowing it to modernize systems more efficiently. Third, our 
preliminary work shows, and some experts agreed, that the ATO should 
provide the administration and Congress with detailed information in 
its budget submissions about the impact of reduced budgets on both ATC 
and NAS modernization. To do so, the ATO should explicitly identify the 
trade-offs it is making to reach administration budget targets, 
highlighting those programs slated for increased funding and those 
slated for reduced funding. 

The ATO Has Made Progress in Addressing Key Challenges and Needs to 
Continue: 

The ATO inherited a decades-long legacy of cost, schedule, and 
performance problems in the ATC modernization program. We found that 
four interrelated factors contributed to these problems. The ATO has 
taken a number of positive steps to address these issues through 
improvements in its management of information technology investments 
and software-intensive acquisitions, but there is room for further 
progress. Additionally, the ATO recognizes that changing its 
organizational culture is a key challenge underlying its transition to 
a highly effective, performance-based organization. Options are 
available to help the ATO address these challenges. 

Four Interrelated Factors Contributed to Acquisitions Missing Cost, 
Schedule, and Performance Targets: 

Our research shows that four common factors emerged that contributed to 
12 of FAA's 16 major systems missing their original cost, schedule, or 
performance targets. (See table 1.) Appendix I provides the full name 
and a description of each of the 16 systems. Appendix II shows changes 
in cost and schedule for these systems.

Source: GAO Analysis of FAA Data: 

[A] Agency approved funding level refers to the annual funding required 
to deliver a system as planned--that is, as documented in an 
acquisition program baseline, the document approved by the agency at 
the beginning of an acquisition. In December 2004, the ATO began using 
the Office of Management and Budget's Capital Asset Plan and Business 
Case (exhibit 300) in place of the acquisition program baseline, as the 
primary decisionmaking document for acquisitions. 

Note: Blank spaces in the chart denote that the specific factor was not 
a key contributor to a program's inability to meet cost, schedule, or 
performance targets. The remaining four major systems we reviewed are 
FTI, ERAM, ECG, and ATOP. FTI's revised baseline reflected increased 
costs to cover requirements which, while included in the original 
baseline, were unknown at the time the original baseline was prepared. 
ERAM, ECG, and ATOP are generally meeting cost, schedule, and 
performance targets. 

[End of table]

According to FAA officials, funding gaps contributed to problems in one 
or more of three areas--cost, schedule, and performance--for 8 of the 
12 system acquisitions. Most major acquisition programs establish a 
baseline that describes the programs' estimated annual costs, planned 
schedules, and performance expectations, which is approved by FAA's 
Joint Resources Council--the agency's executive body responsible for 
approving and overseeing major system acquisitions.[Footnote 3] The 
estimated cost for a given year assumes that the program received all 
funding for prior fiscal years as described in the baseline. In 
practice, however, this is not always the case. For example, when FAA's 
budget level does not allow all system acquisitions to be fully funded 
at the levels approved in their baselines, FAA may elect to fully fund 
higher-priority acquisitions and provide less funding for lower- 
priority acquisitions than called for in their baselines. The ASR-11 
acquisition, a digital radar system, illustrates how reduced funding 
has resulted in cost growth and schedule delays. FAA officials stated 
that because of funding reductions and reprogramming, the program 
received $46.45 million less than requested for fiscal years 2004 and 
2005. According to FAA officials, total costs may escalate and 
schedules may slip under such circumstances. 

The stories behind cost and schedule increases for WAAS--a satellite 
navigation system--and STARS--new controller and maintenance 
workstations--demonstrate how the remaining three contributing factors 
can interact. For WAAS, FAA underestimated the complexity of the 
software that would be needed to support this system when it reduced, 
by 3 years, its plans to develop, test, and commission the system. FAA 
then tried to accomplish these tasks in 28 months, even though the 
software development alone was originally expected to take from 24 to 
28 months. In retrospect, FAA acknowledged that the agency's in-house 
technical expertise was not sufficient to address WAAS's technical 
challenges, particularly the need to warn pilots in a timely manner 
when a system may be giving them potentially misleading and therefore 
hazardous information. FAA's efforts to resolve this issue resulted in 
unplanned work, which contributed to a $1.5 billion increase over the 
1994 baseline costs and to a 6-year delay in commissioning the system. 
According to FAA, adding the cost of satellite leases, formerly listed 
as an operating cost, to the capital cost and adding 6 years to the 
program's life cycle also contributed to increased costs. 

For STARS, a joint FAA/DOD acquisition, not adequately including 
stakeholders in development led to unplanned work, cost growth, 
schedule delays, and reduced deployment. Because the program's 
aggressive development schedule allowed for only limited evaluation by 
controllers and maintenance technicians, FAA and the contractor failed 
to recognize human-factors concerns that these stakeholders later 
identified. [Footnote 4] Restructuring the contract to make up for 
these oversights contributed to $500 million in cost growth, a 7-year 
schedule delay, and a reduction in deployment from 172 to 47 
facilities. 

Three of the major ATC system acquisitions are currently operating 
within their original cost, schedule, and performance targets, but have 
exhibited symptoms of past problems, such as requirements growth or 
underestimating the complexity of software requirements. These 
acquisitions include a system for processing flight data for oceanic 
flights (ATOP), a communications system (gateway) for controlling high- 
altitude traffic at 20 en route facilities (ECG), and a replacement for 
the primary computer system used for controlling air traffic (ERAM). 
Despite successes to date, these acquisition programs will require 
sustained management attention to help ensure that they remain within 
their cost, schedule, and performance targets. 

ATO Is Taking Some Positive Steps to Address Legacy Acquisition 
Problems: 

The ATO has already taken some steps to control the legacy problems 
identified with the ATC modernization program.[Footnote 5] For example, 
it has begun to include stakeholders throughout system development, so 
that they can provide input in response to technical or financial 
developments. Reviews of a precision-landing system augmented by 
satellites (LAAS), a digital e-mail-type communication system between 
controllers and pilots (CPDLC), and the next generation air/ground 
communication system (NEXCOM)--each of which had cost, schedule, and 
performance problems to varying degrees--contributed to the ATO's 
reducing or eliminating funding for these systems in FAA's budget 
request for fiscal year 2005. Additionally, the ATO has established 
collaborative teams of technical experts and ATC system users, 
reorganized air traffic services and the research and acquisition 
organization along functional lines of business to bring stakeholders 
together and integrate goals, rewarded cooperation by linking 
investments to operations, started preparing agency planning documents 
in a format consistent with that prescribed by the Office of Management 
and Budget, begun implementing portions of a cost accounting system, 
and reduced layers of management from 11 to 7 to help address the 
hierarchical nature of the organization. 

These are positive steps. We believe the ATO should continue the phased 
approach to acquiring new systems, and involving stakeholders 
throughout a system's development should help avoid the types of 
problems that led to cost growth and delays for STARS. Additionally, we 
view the decision to cut major systems as an indication that the ATO is 
willing to make difficult decisions to suspend major ATC system 
acquisitions that are not achieving their intended goals--even after a 
substantial investment of agency resources. 

FAA has made progress in addressing long-standing problems with 
managing the risks associated with acquiring major ATC systems, many of 
which are software-intensive, but further improvement is possible. For 
example, FAA has established some discipline for acquiring these 
systems through the Acquisition Management System that it began 
implementing after Congress exempted the agency from federal 
acquisition regulations in 1995. Also, FAA has begun basing funding 
decisions for system acquisitions, in part, on their contribution to 
reducing the agency's operating costs while maintaining safety. 
Currently, FTI, a new telecommunications system, is the only 
acquisition that will reduce FAA's operating costs. Most of FAA's major 
system acquisitions are aimed at increasing NAS capacity and delivering 
benefits to users. 

However, as we reported last fall, the Acquisition Management System 
still does not ensure that FAA uses a knowledge-based approach to 
acquisition that is characteristic of the best procurement practices 
used in commercial entities or by DOD. Capturing specific knowledge and 
using it to determine whether a product has reached a level of 
development (product maturity) sufficient to demonstrate its readiness 
to move forward in the acquisition process helps to avoid cost 
overruns, schedule slips, and performance shortfalls that can occur if 
decision-makers commit to a system design before acquiring critical 
technology, design, or manufacturing knowledge. 

FAA has reported that it met its annual acquisition performance goal 
for fiscal year 2004--to meet 80 percent of designated milestones and 
maintain 80 percent of critical program costs within 10 percent of the 
budget, as published in its Capital Investment Plan. In our opinion, 
having and meeting such performance goals is commendable, but it is 
important to note that these goals are updated program milestones and 
cost targets, not those set at the program's inception.[Footnote 6] 
Consequently, they do not provide a consistent benchmark for assessing 
progress over time. Moreover, as indicators of annual progress, they 
cannot be used in isolation to measure progress in meeting cost and 
schedule goals over the life of an acquisition. Finally, given the 
problems FAA has had in acquiring major ATC systems for over two 
decades, it is too soon to tell whether meeting these annual 
performance goals will ultimately improve the agency's ability to 
deliver system acquisitions as promised. 

FAA has made considerable progress in managing its information 
technology investments.[Footnote 7] FAA recently informed us that it 
has taken a number of steps aimed at achieving a higher maturity level, 
including establishing service-level mission need statements and 
service-level reviews, which address operational systems to ensure they 
are achieving the expected level of performance. While these steps 
could resolve some of the deficiencies that we previously reported, we 
have not yet performed our own evaluation of these steps. FAA could 
realize considerable savings if these reviews result in the 
discontinuation of some investments, since operating systems beyond 
their second year of service accounted for 37 percent of FAA's total 
investment in information technology in fiscal year 2004. 

Finally, FAA has made progress in improving its process for acquiring 
software-intensive systems. The quality of these systems and software, 
which are essential to FAA's ATC modernization program, depends on the 
value and maturity of the process used to acquire, develop, manage, and 
maintain them. In response to our previous recommendations, FAA 
developed an FAA-integrated capability maturity model (iCMM).[Footnote 
8] Since FAA implemented the model, a growing number of system 
acquisitions have adopted the model, and its use has paid off in 
enhanced productivity, higher quality, greater ability to predict 
schedules and resources, better morale, and improved communication and 
teamwork. However, while FAA has encouraged process improvement through 
iCMM, use of the model has remained voluntary, and the agency's future 
commitment to this initiative is not certain. Unless FAA demonstrates a 
strong commitment to process improvement and establishes a consistent, 
institutional approach to implementing and evaluating this process 
improvement, the agency risks taking a major step backwards in its 
capabilities for ATC systems and software. 

FAA has also continued to develop an enterprise architecture--a 
blueprint of the agency's current and target operations and 
infrastructure. However, this architecture is still not complete and 
compliance is not yet enforced. We have ongoing work evaluating what 
the agency needs to do to develop and enforce its enterprise 
architecture. 

ATO Recognizes the Importance of Organizational Culture for 
Facilitating Transition: 

Recognizing that cultural factors can play a critical role in an 
organization's success, the ATO has initiated organizational changes 
that are designed to create a foundation for cultural change in the 
acquisitions and operations workforces, which FAA combined to form the 
new organization. For example, the ATO is giving high priority to 
changing its leadership model by linking top management more closely to 
operations in the field and by replacing "command and control" with 
communication across organizational levels. In the past, according to 
the chief operating officer, FAA's management culture was "intensely 
hierarchical, risk averse," and "reactionary." But now, he said, FAA is 
attempting to foster "results-focused, proactive and innovative 
behavior." Changing the agency's leadership model is also designed, he 
said, to replace a "personality-driven culture" with a viable, stable, 
and sustainable organization that can make rational decisions that 
transcend changes in leadership. 

To further support cultural change, the ATO is emphasizing 
accountability and other core values. For example, it is holding 
managers accountable for managing their budgets and in fiscal year 
2006, it plans to include financial management among the pay-for- 
performance criteria for its managers. Additionally, the ATO is using 
the results of the most recent Employee Attitude Survey[Footnote 9] to 
set a baseline for cultural improvement in five core areas--(1) 
integrity and honesty, (2) accountability and responsibility, (3) 
commitment to excellence, (4) commitment to people, and (5) fiscal 
responsibility. FAA's Civil Aerospace Medical Institute analyzed the 
survey results by grouping three to seven survey items under each of 
these areas. For example, FAA placed the survey item "We are encouraged 
to express our concerns openly" with four other items under the 
Integrity and Honesty core value. For many items, across all core 
values, fewer than 40 percent of ATO employees indicated agreement or 
strong agreement. We are comparing the results of FAA's Employee 
Attitude Survey with our 1996 findings identifying culture as a problem 
in the acquisition workforce, which is now within the ATO.[Footnote 10] 
We plan to report our findings later this year. 

It is incumbent upon the ATO, as it moves forward, to follow through 
with its commitment to transform the culture of its component 
organizations. Our studies suggest that transformations need focused, 
full-time attention from a dedicated team. The team must have vested 
authority and resources from top management to set priorities, make 
timely decisions, and move quickly to implement decisions. Such a team 
provides a visible signal that the transition is being undertaken with 
the utmost seriousness and commitment. Having a dedicated transition 
team is just one of several practices that we have identified, such as 
setting implementation goals and a timeline and establishing a 
communication strategy, that are key to successful mergers and 
organizational transformations. (See app. III for a complete list.)

To Address the Challenges of Modernizing and Expanding the NAS While 
Living within Its Means, the ATO Has a Number of Options: 

The ATO faces multiple challenges: (1) expanding and modernizing the 
NAS to accommodate an expected 25-percent increase in the volume of air 
traffic over the next 10 years; (2) hiring thousands of air traffic 
controllers to replace those expected to retire over the next decade; 
(3) working with the new JPDO to coordinate the research efforts of 
diverse federal agencies to transform the NAS to meet potential air 
travel needs of 2025; and (4) addressing aging infrastructure. The ATO 
faces the additional challenge of accomplishing these tasks with less 
funding than it has received in the past. A number of options are 
available for the ATO to consider in addressing these challenges. 

The ATO plans to continue modernizing and expanding the capacity of the 
NAS to accommodate an expected 25-percent increase in air traffic 
volume over the next 10 years. Even after cuts to the LAAS, CPDLC, and 
NEXCOM budgets, the remaining major ATC systems would consume $4.4 
billion, or 45 percent of FAA's total planned funding (excluding 
personnel and travel) for fiscal years 2005 through 2009. The funding 
situation is further exacerbated by the ATO's need to hire and train 
thousands of air traffic controllers to replace those reaching 
retirement eligibility over the next decade. (See fig. 1.)

Figure 1: Projected Controller Retirements, Fiscal Years 2005-2014: 

[See PDF for image]

[End of figure]

Additionally, as the ATO works with the JPDO to address the NAS's 
potential needs 20 years into the future, it will need to ensure 
linkage to and continuity with its own 10-year plans. The JPDO is 
responsible for developing a national vision and plan that will prepare 
the NAS to meet an assumed tripling of air traffic demand by 2025. In 
its first report, in December 2004, the JPDO concluded that meeting 
this demand would require a complete transformation of the NAS. It also 
predicted that fossil fuels would become less available and more 
costly, and global travel and commerce would become more 
interdependent. As one senior JPDO official suggested, if we fail to 
consider these issues now, future passengers may not be able to fly to 
their destinations in a single day and overnight package delivery may 
become a thing of the past. While the JPDO's plan did not discuss 
costs, the Vision 100--Century of Aviation Reauthorization Act 
authorized $50 million annually for fiscal years 2004 through 2010 for 
the JPDO. 

The ATO will be challenged to harness the efforts of the diverse 
agencies that participate in the JDPO, including DOD, the Department of 
Homeland Security and the National Aeronautics and Space 
Administration, and to align these efforts with the goals of the 
national plan. Although a relatively new organization, the JPDO has 
defined eight interdependent strategies to guide its work towards 
transforming the NAS and has established integrated product teams, each 
led by a participating federal agency, to address each of these 
strategies. These agencies have historically "gone their own way," with 
little thought given to coordinating with other agencies and moving 
toward a common goal. Aviation experts told us that within FAA, there 
is resistance to having outside organizations, rather than FAA, develop 
new procedures and systems for FAA to approve and institute. This will 
have to change under the JPDO paradigm. 

Additionally, the ATO has cited the need to renew its aging 
infrastructure. The ATO estimates that such renewal will require an 
annual investment of $2.5 billion, assuming a $30-billion value of its 
assets and 7-to 12-year useful lives. According to the ATO, much of its 
physical infrastructure, including the buildings and towers that house 
costly ATC systems, is over 30 years old on average.[Footnote 11] (See 
table 2.)

Table 2: Age of NAS Facilities: 

Facility: En route traffic control facilities; 
Average age: 40 years. 

Facility: Air traffic control towers; 
Average age: 30 years. 

Facility: Terminal approach control centers; 
Average age: 34 years.

Continued Reductions in Funding Levels Will Challenge the ATO's Ability 
to Live within Its Means: 

Because Office of Management and Budget funding targets for fiscal 
years 2005 through 2009 are lower than those for recent fiscal years, 
the chief operating officer predicts a cumulative $5-billion gap in 
operations funding and a $3.2-billion gap in capital funding. He said 
that, in effect, remaining within these lower targets would require a 
21-percent reduction in costs and a 9-percent increase in productivity. 
The chief operating officer also predicts that currently planned cost- 
saving measures would produce only half of the needed savings. One 
aviation expert predicted that the gaps would more likely have a 
gradual effect, rather than an immediately catastrophic effect, 
manifested by a slow but sure increase in air traffic delays. 

To provide the $4.4 billion needed for its major system acquisitions 
while remaining within its budget targets through fiscal year 2009, the 
ATO has made significant cuts elsewhere in its capital funding plans. 
For example, the ATO eliminated all of the $1.4 billion that it had set 
aside for what it calls the "architecture segment." (See fig. 2.) These 
funds would have been used to perform about 2 years' worth of early 
research on new programs before they are mature enough to receive 
formal Joint Resources Council approval. The ATO also made significant 
reductions in planned investments for facilities--an action that runs 
counter to its reported need to refurbish or replace its physical 
infrastructure.

Compared with January 2003:

[End of figure]

Such reductions reflect the end result of difficult decisions about 
which programs to fund and which to cut in order to remain within the 
administration's budget targets. However, when forwarding its budget 
submission for administration and congressional review, the ATO does 
not highlight the programs slated for increased or reduced funding and 
does not identify the impact of these decisions on ATC and NAS 
modernization. Such information would make clear how constrained 
budgets will affect NAS modernization and how the ATO is working to 
live within its means. 

The ATO Has Options to Increase Its Prospects for Success: 

Contracting out more services and proposing legislation to provide 
borrowing authority are two options proposed by aviation 
experts[Footnote 12] to improve the ATO's chances of success. A third 
option, providing more clarity in budget submissions, is supported by 
our work and some experts. 

First, some members of our expert panel suggested that the analysis 
performed on contracting out flight service stations could be extended 
to other functions, such as oceanic or en route air traffic control, or 
nighttime operations. Under this option, experts said that ongoing 
government oversight could ensure the safety of contracted operations, 
and such a "staged outsourcing" of the NAS's functions might build 
confidence in the private sector's ability to provide air traffic 
services safely and efficiently. We view the agency's decision to study 
the contracting out of flight services as a significant step towards 
cost reduction and one that could be selectively expanded to other 
services if the current experience proves positive. 

Second, some experts suggested that the ATO finance its capital 
investments by incurring debt through private capital markets, rather 
than relying on annual appropriations. While we have consistently 
maintained that Congress should control new funding sources through the 
budget and appropriations processes, these experts believed that debt 
financing would increase the ATO's flexibility by providing a 
dedicated, multiyear source of funds that it could manage as program 
needs dictate, thereby allowing it to modernize more efficiently. A 
legislative change would be required to give the ATO borrowing 
authority. 

Our preliminary work shows, and some aviation experts maintain, that 
the ATO needs to prioritize its capital investments, as well as its 
investments in operating systems, with affordability in mind. These 
experts believe that the ATO needs to review all of its spending plans 
for modernization, determine which programs can realistically be 
funded, and select programs to cut. They also indicated that the ATO 
should have a mechanism to explain to Congress the implications that 
cutting the funding for one system has on other systems. Indeed, the 
ATO appears to be prioritizing its investments, as indicated by the 
varying percentage reductions in various planned capital investments. 
We believe that the ATO could clarify how these trade-offs affect 
progress in modernizing the ATC system and related components of the 
NAS in the near, mid-, and longer term. Such transparency would provide 
senior agency officials and Congress with a clear view of how the ATO 
is working to live within its means. 

In summary, we believe that the ATO has taken a number of positive 
steps. With continued management attention and focus to carry the 
momentum forward, the ATO has an opportunity to address its heretofore 
intractable problems with ATC modernization. 

This concludes my statement. I would be pleased to respond to any 
questions that you or other Members of the Subcommittee may have at 
this time.

Appendix I: Major ATC System Acquisitions: 

Air Traffic Control Radar Beacon Interrogator - Replacement (ATCBI-6): 

ATCBI-6 is a replacement radar capable of determining both range and 
direction to and from the aircraft. It can also forward this 
information to the appropriate air route traffic control centers. It 
will replace radars that have exceeded their life expectancy and have 
proved extremely vulnerable to outages and critical-parts shortages. 

Advanced Technologies and Oceanic Procedures (ATOP): 

ATOP is an integrated system of new controller workstations, data- 
processing equipment, and software that will enhance the control and 
flow of oceanic air traffic to and from the United States. ATOP is 
planned for the three sites that control oceanic air traffic: 
Anchorage, Alaska; New York, New York; and Oakland, California. 

Airport Surface Detection System - Model X (ASDE-X): 

ASDE-X is an airport surveillance system that enables air traffic 
controllers to track the surface movement of aircraft and vehicles. The 
detection system automatically predicts potential conflicts and 
seamlessly covers airport runways, taxiways, and other areas. 

Airport Surveillance Radar Model-11 (ASR-11): 

ASR-11 is a digital radar that replaces aging analog radars, such as 
ASR-7 and ASR-8, with a single, integrated digital radar system. ASR-11 
reduces operational costs, improves safety, and can accommodate future 
capacity increases. 

Controller-Pilot Data Link Communications (CPDLC): 

CPDLC is a communication system that will allow pilots and controllers 
to transmit digital data messages directly between FAA automated ground 
computers and aircraft. 

En Route Automation Modernization (ERAM): 

ERAM will replace software and hardware in the host computers at FAA's 
20 en route air traffic control centers, which provide separation, 
routing, and advisory information. It provides a flexible and 
expandable base to facilitate further national airspace system (NAS) 
modernization initiatives. 

En route Communications Gateway (ECG): 

ECG provides a communications interface between radar sites and en 
route centers, and is a precursor to ERAM. The system has an open and 
expandable platform that allows for new connectivity and functionality 
as the NAS evolves. It replaces the interim Peripheral Adapter Module 
Replacement Item that has been operating for 10 years and has exceeded 
its life expectancy. 

FAA Telecommunications Infrastructure (FTI): 

FTI is FAA's new telecommunications system. It will replace costly 
networks of separately managed systems and services--both leased and 
owned--by integrating advanced telecommunications services within FAA's 
NAS and non-NAS infrastructures. 

Free Flight Phase 2 (FFP2): 

FFP2 is a suite of air traffic control tools and subsystems that allows 
air traffic controllers to move gradually from a highly structured 
system, based on elaborate rules and procedures, to a more flexible 
system wherein pilots, within limits, can change their route, speed, 
and altitude while keeping air traffic controllers informed of such 
changes. It includes the Traffic Management Advisor, Collaborative 
Decisionmaking, User Request Evaluation Tool, and the Surface 
Management Advisor. 

Integrated Terminal Weather System (ITWS): 

ITWS is a weather information system that furnishes air traffic 
controllers and supervisors with full-color graphic displays of weather 
conditions that need no meteorological interpretation. It provides a 
comprehensive representation of the current weather situation and 
precise 20 minute forecasts (to be increased to 60 minutes in 2006) of 
convective weather conditions. 

Local Area Augmentation System (LAAS): 

LAAS is a landing guidance system that would use global positioning 
satellites and would be installed at airports to allow aircraft to 
execute precision instrument approaches and landings in all weather 
conditions. LAAS would eliminate the need for multiple instrument 
landing systems at airports where it is installed. 

NAS Infrastructure Management System--Phase 2 (NIMS-2): 

NIMS is a centralized system to help manage and schedule maintenance on 
the NAS infrastructure, including its facilities, systems, and 
equipment. NIMS will decrease the number of en route delays by reducing 
the time required to restore systems to full operation following 
maintenance. NIMS Phase 1, already complete, provides initial 
Operational Control Center capability, along with remote monitoring and 
control functionality, to 3,700 NAS facilities and 5,800 deployed 
maintenance data terminals.[Footnote 13] Phase 2 will fully implement 
resource management and enterprise management software and focus on 
increasing workers' productivity in receiving orders and managing 
resources. 

Next Generation Air/Ground Communications (NEXCOM): 

NEXCOM is a digital communications system, consisting of multimodal 
digital radios, avionics, and ground stations, which will improve air 
traffic control communications by replacing old analog communication 
systems. Segment 1A will replace 30-to 40-year-old radios, deploying 
6,000 new radio sets that use analog and digital communications with 
aircraft. Segment 1B will create ground stations to communicate with 
aircraft equipped with digital capability. 

Operational and Supportability Implementation System (OASIS): 

OASIS a system used at flight service stations to assist general 
aviation pilots with flight planning. The system provides up-to-the- 
minute weather graphics by integrating real-time weather and flight 
planning data with overlays of flight routes. It replaces the Flight 
Services Automation system for which spare parts and hardware support 
have been difficult for FAA to obtain. 

Standard Terminal Automation Replacement System (STARS): 

STARS is workstation to allow civilian and military air traffic 
controllers to direct aircraft near major U.S. airports and will 
replace aging workstations at certain facilities. It has an open and 
expandable terminal automation platform that can accommodate air 
traffic growth, as well as new hardware and software that is designed 
to promote safety, maximize operational efficiency, and improve 
controllers' productivity. 

Wide Area Augmentation System (WAAS): 

WAAS is a navigation and landing guidance system that uses global 
positioning satellites to provide precise navigation and landing 
guidance at all airports, including thousands that have no ground-based 
instrument landing capability.

Source: GAO presentation of FAA data. 

[A] FAA plans to extend ASDE-X's current deployment target from 2007 to 
2009 because the project's budgets were cut in fiscal years 2004 and 
2005. 

[B] According to FAA officials, the change in cost target for ASDE-X 
was due to an increase in the scope of the project. 

[C] The increased costs were for requirements which, while included in 
the original baseline, were unknown at the time the original baseline 
was prepared. 

[D] In light of reduced funding, FAA is revising NIMS-2's targets; 
a Joint Resources Council decision is planned for May 2005. 

[E] According to FAA, adding the cost of satellite leases, formerly 
listed as an operating cost, to the capital cost and adding 6 years to 
the program's life cycle contributed to increased costs.
