SYSTEM AND METHOD FOR TACTILE CUEING THROUGH ROTORCRAFT PILOT CONTROLS USING VARIABLE FRICTION AND FORCE GRADIENT

摘要

An rotorcraft (101) including a pilot control, a pilot control position sensor (215) connected to the pilot control and operable to generate a position signal indicating a position of the pilot control, a flight control computer (FCC) (205) in signal communication with the pilot control position sensor (215) and operable to provide a tactile cue in the pilot control in response to the position signal indicating the position of the pilot control exceeds a threshold (703) associated with an operating limit, and further operable to determine a tactile cueing value for the tactile cue according to a relationship between the position of the pilot control and the threshold (703), and generate a cue control signal according to the tactile cueing value, and a tactile cue element connected to the pilot control and in signal communication with the FCC (205) and operable to control action of the pilot control in response to the cue control signal.
