Pilot-aircraft system response to wind shear

The nonlinear aircraft motion and automatic control computer model of Frost and Reddy has been expanded to incorporate the human pilot into simulations of aircraft response to wind shear. The human pilot is described by a constant gains lag filter. In addition, two runs are carried out using pilot transfer functions from the experimental data of Adams and Bergeron. Fixed-stick, autopilot, and manned computer simulations are made with an aircraft having characteristics of a Queen Air (small commuter-type aircraft) flown through longitudinal winds measured by a Doppler radar beamed along the glide slope during the SEsAME '79 experiments in Oklahoma. Simulations are also made flying an aircraft characteristic of a Boeing 727 through sinusoidal head wind and tail wind shears at the phugoid frequency to evaluate the response of manned aircraft in thunderstorm wind environments.
