GAO’s reports and testimonies give Congress, federal agencies, and the public timely, fact-based, non-partisan information that can improve government operations and save taxpayers billions of dollars.
What GAO Found Although advances in technology have led to increasingly quieter airplanes, community concerns about aircraft noise have persisted. One concern relates to FAA's implementation of performance-based navigation (PBN), which may concentrate aircraft noise over a smaller area.
Why This Matters Uncrewed aircraft systems, or "drones," can pose safety and security risks to critical U.S. sites and may be used for smuggling or other criminal activity. With over 2 million drones projected in the U.S. by 2024, these risks are likely to grow.
What GAO Found Starting in January 2020, presidential executive actions imposed restrictions on international air travel to the U.S. from certain countries and mandated that face masks be worn on transportation systems, due to COVID-19.
What GAO Found The COVID-19 pandemic severely affected the aviation and aerospace sectors that depend on commercial passenger travel. As demand for air travel plummeted and remained low throughout 2020, effects cascaded across sectors including U.S.
What GAO Found Executive branch agencies' revenues from dedicated user fees were lower in fiscal year 2020 and in the first half of fiscal year 2021 compared to average annual revenues in fiscal years 2017 through 2019, the 3 fiscal years prior to the start of the COVID-19 pandemic.
