A model of the pilot-aircraft system which can relate the pilot tracking performance attainable with specific aircraft dynamics to the over-all accuracy of tactical weapon delivery is required in order to realistically determine essential flight control system dynamic performance characteristics. The approach taken is to derive a linear expression for projectile impact error in terms of errors in the task variables which are directly under the pilot's control. A statistical model of the propagation of these pilot-induced errors into impact error is then developed by considering each of the pilot inputs to be random variable. An analytical model of the human pilot is used to estimate the tracking error from the flight control system and aircraft dynamics and the turbulence environment. The model is further refined as a result of piloted simulation studies to include important cross-coupling effects. The resulting model represents a method for relating impact accuracy to design of the manual flight control system and provides a technique for comparative evaluation of display, computation, and control aids to the tactical pilot.
