Abstract:

The report describes the Piper PA-30 Twin Comanche aircraft and a representative autopilot during the final approach configuration for simulation purposes. The aircraft is modeled by linearized six-degree-of-freedom perturbation equations referenced to the aircraft stability axis. Other equations are presented which derive the body axis rates, velocities and accelerations, and ground referenced velocities translation equations. The autopilot is a representative system for automatic ILS approaches from initial localizer track down to decision height. The glideslope system is engaged by approaching the glidepath at constant altitude usually in the altitud hold mode on the localizer beam. The pilot must take over manually at the decision height since light aircraft are not normally equipped with automatic flare capability. The aircraft autopilo model described herein has been used extensively in simulation studies at TSC and exhibits the expected behavior.
