Auto-GCAS stands for Automatic Ground Collision Avoidance System and plays an important role in safety for fighter pilots when they enter into combat. According to the Society of Automotive Engineers, a large number of fatal accidents happen on the ground, or what is often referred to as Controlled Flight into Terrain (CFIT). Due to the high-level of collisions both mid-level air and on the ground, the Defense Safety Oversight Council (DSOC) partnered with the Air Force Research Laboratory (AFRL) to design a way to keep fighter pilots safer and less prone to CFIT. The result is the implementation of Auto-GCAS on F-16 Fighting Falcons and the Lockheed Martin F-35 Lighting II aircraft.
A number of different factors can cause CFIT including unconsciousness and distraction and – until Auto-GCAS – pilots had no way to combat or prevent CFIT. The F-16 and the F-35 aircrafts now have Auto-GCAS to fight the dangers of CFIT and to reduce the number of related incidents. It does so through intricate algorithms and what is referred to as a digital terrain database; in other words, the technology can detect an impending crash, take control of the aircraft, and completely avoid contact with the imminent terrain. Specifically, SAE mentions that once the Auto-GCAS system determines that a crash is inevitable, it takes control, rolls to wings level, and executes a 5g pull until the aircraft clears the terrain.
Mark Wilkins and Finley Barfield received the prestigious Robert J. Collier Trophy from the National Aeronautic Association for their contribution to Auto-GCAS systems. SAE notes that since the F-16 was equipped with Auto-GCAS in 2014, seven airplanes and eight pilots have been saved. The hope is that further integration and innovation will take place, including further implementation of automatic air collision avoidance systems, implementation of ground/air collision avoidance systems and ways to implement Auto-GCAS into larger aircraft and unmanned aerial machines.
