Runway takeoff monitor

摘要

Disclosed is a runway alerting method and system for an aircraft during a take-off maneuver. The method includes determining stopping positions for the aircraft along the runway using aircraft energy state, deceleration and braking information and displaying the stopping positions on a display.

1. A runway alerting method for an aircraft attempting a take-off maneuver, comprising:
determining, in a processor, stopping positions for the aircraft along the runway using aircraft energy, deceleration and braking information, the stopping positions including at least a minimum stopping position and a corporate stopping position, wherein the minimum stopping position and the corporate stopping position are determined using the equation:Stopping⁢⁢point=Brkon⁢Pt+V22×A  Where:
BrkonPt is the position on the runway (distance from runway start) where the brakes are predicted to be applied;V is the predicted velocity of the aircraft at the brakes-on location as determined by aircraft speed sensors and assumed speed loss that would occur before the brakes are applied; and|A| is the absolute value of the acceleration (deceleration being a negative value) using the appropriate deceleration depending on which predicted stopping point is being computed; and displaying, by the processor, the stopping positions on a display.
