Enhanced Aircraft State Display for Improved Situation Awareness of Flight Envelope Limitations

In the case of an aircraft system failure such as control surface or engine failure, an aircraft’s flight envelope may change. Notifying the pilots of these changes may improve situational awareness and, hence, increase flight safety because pilots will have additional knowledge about maneuver limitations to stay safely within the flight envelope. Also, notifying the pilots of where the vehicle is relative to maneuver limitations may further increase safety by assuring pilot’s knowledge of the aircraft state.
