The Federal Aviation Administration's (FAA) process for ensuring that air traffic control (ATC) systems will operate safely in the national airspace system is an integral part of the agency's multibillion-dollar ATC modernization and safety effort. GAO was asked to review (1) FAA's process for approving ATC systems for safe use in the national airspace system; (2) challenges FAA has faced approving ATC systems and how these challenges affected the cost, schedule, and performance estimates of the systems; and (3) actions FAA has taken to improve its process for approving ATC systems. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-05-11/html/GAOREPORTS-GAO-05-11.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-05-11/pdf/GAOREPORTS-GAO-05-11.pdf GAO-05-11 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-05-11 Other Written Product GAO-05-11; Air Traffic Control: FAA Needs to Ensure Better Coordination When Approving Air Traffic Control Systems; Air traffic control systems Air traffic controllers Aircraft Aviation Internal controls Safety standards Strategic planning Systems design Transportation safety Title 31 Section 1535 31 U.S.C. 1535
