Computer-aided fighter pilots

Article Abstract:

Lockheed Corp engineers developing an artificial intelligence (AI)-based project to aid fighter pilots in flight could not decide between two design approaches: a conventional expert system using a fixed knowledge base about tactical air combat or an expert system that modified its responses to the pilot's flying style. Rather than decide between the two, Lockheed decided to proceed with two development teams, one working on each approach. The fighter jet environment required that the expert system respond in real time and that it suppress unnecessary details. Development of the Pilot's Associate (PA) system, which took the novel AI approach, required input from human-factors specialists to determine how best to display the information, from psychologists about pilot performance standards in combat, and from engineers to define the operational characteristics that had to be monitored by the expert system. The design and operation of PA are described.
