Abstract
A system and method for detecting ground resonance and providing a warning regarding the same includes supplying, from an inertial navigation system (INS), inertial data indicative of an inertial profile of a rotorcraft, and supplying, from a sensor system, sensor data that indicates when the rotorcraft is at least partially on a landing surface. The sensor data is processed, in a processing system, to determine when the rotorcraft is at least partially on the landing surface, and when the rotorcraft is determined to be at least partially on the landing surface, the inertial data is processed, in the processing system to determine when the inertial profile of the rotorcraft indicates ground resonance may occur. Upon determining that ground resonance may occur, one or more alert signals are generated in the processing system.
