Abstract : Military Specification MIL-F-008785A (USAF), 'Flying Qualities of Piloted Airplanes,' was evaluated by conducting a detailed comparison of its requirements with the known characteristics of a modern, high-performance, multi-mission weapon system, the McDonnell Douglas F-4. The comparison was based primarily on already available flight test data with pilot comments or ratings used to evaluate the specification requirements for the various parameters. The comparison presents the basic characteristics of the F-4B, C, D, E, and J models which includes the effects of four types of longitudinal feel systems. Also presented is the difference in power approach characteristics resulting from incorporation of the Rolls Royce engine in the F-4K/M aircraft. Flight test data are supplemented, as necessary, with analytical evaluations of handling qualities parameters, not available from test data, which were computed from available F-4 aerodynamic derivatives. Reliability data, taken from the operational history of the F-4, are included to show the probability of pertinent primary aircraft systems failure and/or of mission abort. (Author)
