Embedded Ground Proximity Warning System for Helicopters

Abstract

A system for warning a pilot of a helicopter of a flight-into-terrain hazard includes a signal processing component that determines helicopter flight conditions by fusing data obtained from multiple flight condition data sources, a protection component that communicates with the signal processing component, determines whether a potential controlled flight-into-terrain hazard exists by computing predicted recovery trajectories based upon flight conditions and characteristics of the helicopter and decides upon a recovery trajectory, and a pilot interface component that provides a directive to the pilot to indicate the decided-upon recovery trajectory if multiple predicted recovery trajectories indicate a terrain impact will occur.
