The application of Active Controls Technology to Short Take Off and Landing aircraft is investigated. The investigation is restricted to a longitudinal ride comfort control system. A typical STOL aircraft is modelled as well as an altitude hold autopilot to provide a comparison for the study. Etkin's four point model for response to turbulence with a Von Karman spectrum is used as turbulence model in the performance analysis. Optimal control theory is used to design an optimal altitude hold autopilot for the aircraft. Using this control system a 98 percent reduction in load factor is achieved. As a consequence of this improvement, the wing root bending moment due to turbulence is reduced to 20 percent of its original value.
