Auto-ACAS - Robust Nuisance-Free Collision Avoidance

During 2000 - 2004, a concept for an Automatic Air Collision Avoidance System (Auto-ACAS) has been developed and demonstrated in simulations and flight test with F16 aircraft. The system performs coordinated automatic evasive maneuvers when collisions are imminent, still allowing the pilots to fly the aircraft according to regulations without creating nuisance activations. The performed simulations and flight tests have shown successful results and the concept is proven to be suitable for use in modern fighters as well in UAV’s and other platforms. The ability of the system to handle complex situations with multiple involved aircraft performing highly provocative maneuvers has been above all expectations. We here briefly present the system design, testing and conclude the work done in the joint Swedish and USA program.
