Abstract: An autonomous weapons system simulation is generated on board an aircraft and in flight, displaying virtual scenarios with a simulation of weapons systems on board the aircraft and computer-generated ground-to-air and air-to-air threats. The weapons system simulation system permits a real-time air combat training on board of combat aircraft which is carried out with and/or against computer-generated forces, and the implementation takes place by the integration of the crew in virtual scenarios with virtual partners, targets and enemies in the usual cockpit and display environment.
