A basic design concept of a flight director system (FDS) is developed in an effort to examine backside operations during the approach phase, centering on the transient responses at the time of the shift to the ILS step and the stability during the following steps. This FDS has three commands: pitch command, flight path command and bank command. Equations are formulated to generate these commands. To determine the flight-director dynamics, models of pilots, FDS and STOL research aircraft are developed on the assumption that they can be connected linearly, and dynamic responses of the entire system are calculated. To set up parameters based on responses of the system, examination is made of a stabilization/control system model, pilot model for pitch control, wash-out time constant of the pitch command loop, pilot model for speed control, glide slope capture characteristics, localizer deviation correction characteristics and localizer capture characteristics.
