Abstract

Real Time Detection of a Pilot -Induced Oscillation (PIO) can potentially save both aircrew and aircraft. This paper evaluates the ability of one specific real time detection technique, ROVER (Real Time Oscillation Verifier), with two recent flight test time histories of a modern day fighter aircraft involving PIO episodes. Although limitations of the algorithm do exist, ROVER, if used correctly, will detect a severe PIO event and could allow a pilot to open the feedback control loop or adjust the control input strategy in order to suppress the aircraft oscillatory response.
