Loop Separation Parameter (LSP) is a method used to evaluate the flying qualities of landing aircraft. It combines classical root locus and frequency response methods with simple and intuitive pilot models to predict expected pilot ratings for aircraft in the landing phase. In previous work LSP has shown good correlation with pilot ratings for fighter-type aircraft, but it was not used as a predictive tool on configurations independent of the original study. In this research, the LSP method is applied as a predictive tool to both fighter-type and large aircraft configurations which are independent of the original data base. The large aircraft are representative of transport, bomber, and highly augmented space shuttle configurations. Good correlation between LSP predicted and actual pilot ratings for landing is shown. In addition, insightful modifications to the original method lead to improved correlation for all aircraft configurations. Recommendations include the consideration of LSP for the Flying Qualities Handbook. This would represent the first use of pilot models in a handling qualities specification.
