What exactly does the OVERSPEED feature do?
The aircraft’s airspeed is continuously monitored and alerts the pilot when he/she is at an overspeed (Vne) condition. The overspeed threshold value is hardwired during installation for the specific make and model of aircraft. As the aircraft reaches the airspeed threshold, the message, “OVERSPEED!…OVERSPEED!…OVERSPEED!” repeats and is accompanied by the flashing amber annunciator. Slowing the aircraft is the only way to stop these advisories.
