## Highlights

To prepare for forecasted air traffic growth, the Federal Aviation Administration (FAA), in partnership with other federal agencies and the aviation industry, is planning and implementing the Next Generation Air Transportation System (NextGen), a new satellite-based air traffic management system that will replace the current radar-based system and is expected to enhance the safety and capacity of the air transport system. GAO was asked to review FAA's metrics for (1) tracking the status of NextGen programs and the implementation of NextGen capabilities, the reliability of those metrics, and any limitations or gaps and (2) measuring the performance and outcomes of NextGen capabilities that are implemented and any limitations. GAO analyzed FAA program progress reports and associated metrics for monitoring. GAO also reviewed agency performance and accountability reports and discussed internal performance reporting methods with FAA officials.
