Abstract : CROSSWIND LANDINGSThe application of Direct Side Force Control (DSFC) during crosswind landings of an airplane having the characteristics of a Class II STOL was investigated in the USAF Total In-Flight Simulator (TIFS) airplane. The primary purpose was to evaluate the usefulness of DSFC during the crosswind landing. Other objectives were to investigate the type of cockpit controller or mechanization scheme for use with DSFC, and to define parameters which affect pilot workload during crosswind landings with DSFC. Landing approaches to simulated touchdown were flown both without and with the aid of DSFC. The approach speed was 130 knots. Two modes of DSFC control were investigated, an independent manual control of DSFC through a cockpit mounted thumbwheel proportional controller, and an automatic scheme which tracked the ILS localizer signal.
