A great deal of research has been devoted to the development of a human pilot describing function model for single axis compensatory tracking tasks and as a result the model has shown good repeatability in predicting pilot behavior. The extension of the single axis model to the more pragmatic multiloop control situation is somewhat tentative at present but does not seem to be an unreasonable extrapolation. Application of the pilot model to the development of a flexible and objective handling qualities theory holds real promise however, further definition of the subjective pilot opinion rating - pilot model parameter link is required. A beneficial approach along these lines would be flight testing for pilot behavior characteristics in all new or existing aircraft weapons systems. An alternate approach to the pilot modeling is the sampled-data model and certain control situations warrant its use. The sample remnant model discussed may provide a suitable matching of approaches with more research.
