A flight investigation has been conducted to determine the acceptability of a small side-located controller which is used as the primary airplane controller in an irreversible hydraulic-power control system. The particular controller used in this investigation requires up and down hand motion pivoting at the wrist for longitudinal control and lateral hand or forearm motion for lateral control. Pilot opinion was obtained concerning the acceptability of the controller while performing lateral and longitudinal maneuvers in a jet-trainer airplane at cruising-flight conditions.
