Autonomy Architecture Prevents Aviation Accidents

November 17, 2021

There have been approximately 1,200 to 1,300 general aviation accidents per year since 2013, which is down from the years before. While the improvement is good, NASA is working to decrease the number of aircraft crashes even more. NASA, the FAA, and the Department of Defense developed the Expandable Variable Autonomy Architecture that can help prevent accidents in general aviation aircraft and future autonomous aircraft.

The Expandable Variable Autonomy Architecture  is based on an earlier NASA-developed technology that performs a similar function for military aircraft. EVAA includes functions to prevent smaller airplanes from diving into a canyon, into the side of a mountain, or into the ground by avoiding obstacles and guiding the plane to a safe landing area. An element in the software, called the Moral Compass, helps decide which moves to make by switching control to the highest priority task based on weighing the odds of safety.
