Emerging simulation technologies provide new opportunities for training mission tasks and skills which have not been previously trained in simulators. Research is necessary to identify the tasks where additional training would most benefit mission ready pilots and air weapons controllers and which of these tasks represent training opportunities for networked simulators. Armstrong Laboratory, Aircrew Training Research Division has recently developed a SIMNET compatible network of F-15 cockpits with visual systems, an air weapons controller station, manned and digital threats, and an exercise control station. An evaluation of this system was conducted in which 23 F-15 pilots 13 air weapons controllers participated in simulated air combat exercises. Each team of lead pilot, wingman, and controller flew several offensive and defensive counter air missions against a force of up to six aircraft, anti-aircraft artillery, and surface to air missiles. Participants were asked to rate their interest in receiving additional training on each of 36 mission areas. After participating in the simulated air combat exercises, participants rated the value of the training received in the simulator system and the training currently received in their units for each of these mission areas. Data presented identifies, a) tasks which are of particular interest to aircrews, b) which tasks were better trained in the simulation system than in current unit training, and c) changes in pilot performance in simulated air combat related to levels of fighter experience.
