Automatic Ground Collision Avoidance System
Auto-GCAS USAF F-35

The Automatic Ground Collision Avoidance System (Auto-GCAS) enhances safety by mitigating controlled flight into terrain (CFIT) accidents. [1] The Auto-GCAS team was awarded the 2018 Collier Trophy for the design-integration and flight testing in the F-35, marking the year's greatest achievement in aeronautics.[2] This team includes the Air Force Research Laboratory, Lockheed Martin, the F-35 Joint Program Office, the Defense Safety Oversight Council, and NASA.[2]

Automatic Ground Collision Avoidance System

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.[3] 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 F-16 pilot fatalities. [3]

NASA started working on Auto-GCAS starting in 1997.  [4] The system was then jointly developed at the Lockheed Martin [3]Skunk Works and at NASA. In July 2019, seven years ahead of schedule, Lockheed Martin started integration of Auto-GCAS into the F-35 fleet. [5]
