To prepare for forecasted air traffic growth, the Federal Aviation Administration (FAA), including its Joint Planning and Development Office (JPDO) and Air Traffic Organization (ATO), is planning for and implementing the Next Generation Air Transportation System (NextGen) in partnership with other federal agencies and the aviation industry. NextGen will transform the current radar-based air traffic control system into a more automated aircraft-centered, satellite-based system. GAO's previous work has identified issues related to the usefulness of NextGen planning documents, FAA's organizational structure to manage the transition to NextGen, and FAA's workforce to oversee and implement NextGen. Recently, the focus of NextGen planning and implementation has shifted to capabilities that can be achieved in the midterm, defined as 2012 through 2018. GAO's testimony focuses on (1) JPDO's and ATO's progress in planning NextGen and changes in the NextGen management structure; (2) ongoing efforts to implement midterm capabilities to address capacity constraints, and issues related to these efforts; and (3) key human capital issues, research and development needs, and facilities maintenance and reconfiguration challenges going forward. GAO's testimony updates prior GAO work with FAA data and interviews with agency and union officials and industry stakeholders, including airline, aircraft, and avionics manufacturer representatives.

JPDO and ATO have made progress in planning for and developing NextGen. JPDO has continued to update its basic planning documents, and in January 2009, ATO released the current version of its NextGen Implementation Plan, which focuses on the midterm implementation of capabilities. Recent versions of NextGen planning documents have partially addressed some of GAO's previously reported concerns about their usefulness, but industry participants continue to express frustration that the documents lack any specific timelines or commitments. Recent changes in the management structure for NextGen, though designed to address industry stakeholders' and others' concerns about fragmentation of authority and lack of accountability, have not fully addressed these issues and have raised further questions about parties' roles and responsibilities. To help address current congestion and delays, industry stakeholders have frequently suggested that FAA shift its focus from planning for NextGen to maximizing what can be done with existing, proven capabilities and existing infrastructure. In January of this year, FAA created a NextGen Midterm Implementation Task Force, which responds to this suggestion and is to report its recommendations to FAA in August 2009. The task force plans to identify and prioritize capabilities that can be implemented in the midterm and potentially be deployed regionally to address key bottlenecks. Essential to the mid- and long-term success of these efforts is persuading the airlines to make costly investments in NextGen equipment--a step they are reluctant to take without clearly demonstrated benefits. Incentives that could encourage such investments include operational preferences--such as preferred airspace, routings, or runway access--and equipment investment tax credits. FAA will also have to validate, certify, and issue rules for these capabilities. Going forward, FAA faces challenges in resolving human capital issues, addressing needed research and development, reconfiguring and maintaining existing facilities, and enhancing capacity. Human capital issues include involving stakeholders, such as controllers and technicians, in NextGen efforts and acquiring the systems engineering, contract management, leadership, and other skills needed for NextGen. FAA plans to fill 378 NextGen positions in fiscal years 2009 and 2010. Additionally, for NextGen, research and development efforts to address the environmental impact of aviation, human factors, and weather will be critical. Air traffic facilities will also have to be reconfigured to support NextGen, and existing facilities require maintenance to ensure safety and reliability. FAA is currently reviewing its facility needs.Finally, even with the efficiencies anticipated from implementing NextGen, FAA has determined that it will need additional airport and runway capacity. Efforts to enhance capacity will require substantial advance planning and cost and safety analyses.
