A flight investigation was undertaken of the longitudinal handling qualities of the STOL class of aircraft controlled through the modulation of pitch and normal thrust, and flown on steep, instrument landing approaches at low airspeed. Pilots' assessments of the characteristics resulting from independent variations in both short and long term longitudinal dynamics were obtained. It was found that the pitch control characteristics dominated the handling qualities. The more easily and precisely pitch could be controlled, the more adverse the control characteristics of the other degrees of freedom the pilot would accept. When precise long-term control of airspeed through pitch modulation was not difficult, the pilots were prepared to tolerate operation well along the backside of the power-required curve.
