Abstract
A pilot flight control stick haptic feedback system includes a pilot user interface, a position sensor, a pilot motor, and a control circuit. The pilot user interface is movable to a position at a movement rate. The position sensor senses the position of the pilot user interface and supplies a pilot user interface position signal. The pilot motor is coupled to the pilot user interface, and receives pilot motor feedback signals. The pilot motor, in response to the pilot motor feedback signals, supplies feedback force to the pilot user interface. The control circuit determines one or more of the pilot user interface position, movement rate, aircraft control surface slew rate capacity, aircraft control surface load rate capacity, and aerodynamic stall risk and, based on at least a subset of these determinations, supplies pilot motor feedback signals to the pilot motor.
