Abstract
An engine and propeller control system (EPECS) of an aircraft includes a propeller with a plurality of blades coupled to an aircraft engine. Each of the blades are coupled to an actuator configured to adjust the blades between a first pitch to produce forward thrust and a second pitch to produce reverse thrust. The EPECS further includes a controller configured to control the actuator to invoke the second pitch in response to receiving a reverse thrust command signal. The controller is configured to alert that the reverse thrust command signal is generated prior to landing the aircraft.
