[[File:Auto-GCAS Saves Unconscious F-16 Pilot—Declassified USAF Footage.webm|thumb|Footage from the head-up-display of a U.S. Air Force Arizona Air National Guard F-16 records a save by the aircraft's Automatic Ground Collision Avoidance System (Auto-GCAS) during a training mission, the fourth confirmed by the NASA-designed system. From an altitude of just over {{convert|17,000|ft|m|0}}, the pilot executes an 8.1[[G-force|g]] maneuver which causes the pilot to lose consciousness. After the aircraft enters a steepening dive in full afterburner for twenty seconds, Auto-GCAS intervenes with a recovery maneuver at {{convert|8,760|ft|m|0}}, {{convert|652|knots|mph km/h m/s|0|adj=on}} and nose-down almost 55 degrees below the horizon.]]<br />

The Automatic Ground Collision Avoidance System uses inputs from terrain mapping, aircraft location, and automation to avoid ground collisions. The Auto-GCAS system detects imminent ground contact and warns the pilot. If there is no pilot response, the Auto-GCAS takes control, maneuvering to avoid ground contact. When on a safe trajectory, with pilot awareness, control returns to the pilot.<ref name="Lockheed Martin" /> Pilot unresponsiveness can be attributed to many factors including: distraction, task saturation, incapacitation, and unconsciousness. The Auto-GCAS system successfully reduced the leading cause of [[General Dynamics F-16 Fighting Falcon|F-16]] pilot fatalities.<ref name="Lockheed Martin">{{cite web |title=Saving the Good Guys with Auto GCAS Technology |url=https://www.lockheedmartin.com/en-us/products/autogcas.html |website=Lockheedmartin.com |publisher=Lockheed Martin |accessdate=30 May 2020}}</ref><br />

NASA started working on Auto-GCAS starting in 1997.<ref name="NASA">{{cite web |title=NASA-Pioneered Automatic Ground-Collision Avoidance System Operational |url=https://www.nasa.gov/centers/armstrong/Features/Auto-GCAS_Installed_in_USAF_F-16s.html |website=NASA.gov |date=February 11, 2015 |publisher=NASA |accessdate=30 May 2020}}</ref> The system was then jointly developed at the [[Lockheed Martin]] [[Skunk Works]]<ref name="Lockheed Martin" /> and at [[NASA]]. In July 2019, seven years ahead of schedule, Lockheed Martin began integration of Auto-GCAS into the F-35 fleet.<ref name="airforce-technology.com">{{cite web |title=Lockheed Martin integrates ground collision avoidance system in F-35A |url=https://www.airforce-technology.com/news/lockheed-ground-collision-avoidance-f-35a/ |website=airforce-technology.com |date=July 25, 2019 |accessdate=30 May 2020}}</ref><br />
