A two-symbol head-up display design incorporating an optimal form of system equalizing feedback dynamics is conceived as feasible and adequate for the consistently accurate manual control of stereotyped flight profiles. The design provides a compound control symbol for the simultaneous display of stick, throttle and rudder commands. A general systems analysis longitudinal plane illustrates the utilization of this display design in the landing, take-off and weapon delivery modes of flight. The feasibility of this design concept is substantiated by the development of an analytical methodology which directly determines an optimal configuration of system equalizing feedback terms for a given higher order control loop. These feedback signals drive the operators displayed control symbol such as to elicit manual control motions that effect an optimal system response in the cancellation of system error. This equalization methodology is exemplified in the determination of a full complement of implemented feedback terms for the optimal pitch control of a high performance fixed wing aircraft. General observations are made concerning the inclusion and influence of a human operator in an equalized control loop. Author
