Abstract : Computer studies and flight experiments are described which indicate the feasibility of transport aircraft (as represented by the Comet 3B) flying automatic approaches on paths curved in azimuth and elevation. The flight paths considered have radii of curvature from 1800 m to 3000 m in azimuth and the glide paths have maximum gradients from 3 to 6 deg. The effects of various terms in the autopilot control laws are discussed as is the performance in varying wind conditions.
