Abstract:

A new longitudinal flying qualities metric, called Loop Separation Parameter LSP, is intended to correlate with pilot opinion ratings for the landing task. This parameter is based on the observed shift of pilot control emphasis from pitch attitude control during power approach to flight path control during flare to touchdown. The calculation of LSP combines simple, intuitive pilot models with classical root locus and frequency response techniques. In this research, a new criterion based on LSP to predict expected pilot ratings is presented. Although developed from data for fighter-type aircraft, the LSP criterion successfully predicts pilot ratings for large transport and space shuttle configurations as well. This criterion is developed only for aircraft using front-side of the power curve landing techniques. The prediction success of this criterion compares well with the success of MIL-F-8785C Flying Qualities criteria. Recommendations include the consideration of LSP for the Flying Qualities Handbook.
