Patent ID: 11545037

Abstract:
An aircraft-based runway overrun awareness alerting system (ROAAS) for an aircraft primary flight display (PFD) is disclosed. In embodiments, the ROAAS is embodied aboard an aircraft and tracks trends in the aircraft position and heading. Further, the ROAAS tracks the trending energy state of the aircraft on approach to a runway. Based on the current energy state, as well as the runway parameters, the ROAAS predicts a landing point for the aircraft along the runway as a trend based on the evolving energy state and position of the aircraft. Based on the landing point trend, as well as the energy state, the ROAAS determines the current likelihood of runway excursion as an evolving trend (e.g., that the aircraft will not have sufficient runway remaining to decelerate or stop) and displays this likelihood as a dynamic graphic element not integrated into any other instruments or components displayed by the PFD.
