The Pilot Fitness Aviation Rulemaking Committee (ARC) was chartered by the Federal Aviation Administration (FAA) on May 11, 2015, to consider specific objectives and tasks in a forum for the U.S. aviation community to discuss and provide recommendations to the FAA on pilot mental fitness for duty. The ARC was chartered after the Commercial Aviation Safety Team (CAST) considered the circumstances surrounding the Malaysia flight 370 and Germanwings flight 9525 events. CAST ultimately determined it did not have all of the needed expertise to examine pilot mental fitness issues (that is, issues affecting a pilot's emotional state, mental health, or cognitive ability to safely conduct their duties), and a committee of medical and aviation industry professionals with expert knowledge on pilot mental fitness issues was best suited to explore the topic.
