The defense behemoth, which also own Sikorsky helicopters, describes how it works this way on the AGCAS website: “the system consists of a set of complex collision avoidance and autonomous decision making algorithms that utilize precise navigation, aircraft performance and on-board digital terrain data to determine if a ground collision is imminent. In simple terms, the code realizes when the jet is going to fly into the ground and attempts to fix the problem. Lockheed Martin, which manufactures F-16 and F-35 fighter jets, created the AGCAS software. Referring to the altitudes above the ground at which the AGCAS engaged, the Safety Center said: “Based on the airspeed and flight paths of the aircraft, these were the altitudes where the system calculated that immediate flight control input was needed to avoid an impending crash.” The Safety Center added: “In both incidents, the pilots were able to regain consciousness during the AGCAS pull-up and they assisted in the recovery of the aircraft however, their actions alone would not have been in time to prevent collision with the ground.” The Air Force Safety Center explained via email to Popular Science that in both cases, “AGCAS is credited with saving the pilots’ lives.” In the July incident, the software activated at about 4,000 above the deck. The software that saved them is known as Automatic Ground Collision Avoidance System, or AGCAS, and in the January instance, it engaged when the jet was about 2,600 feet above ground level. And in each case, the onboard software system saved the aviators’ lives, according to the Air Force. Both of them would have almost certainly been killed were it not for built-in software that took over the controls before they crashed.īoth pilots experienced an aviation phenomenon called G-LOC, which stands for G-induced loss of consciousness, and both were operating in the Nevada Test and Training Range. Around 6 months later, on July 16, another pilot operating the same type of fighter jet, also in Nevada, passed out as well. On January 23 of last year, a pilot flying a single-seat F-16 over Nevada lost consciousness.
