SYSTEM AND METHOD FOR COMPUTING FLIGHT TIME FROM AN EQUI- DISTANCE POINT TO A REFERENCE POINT

摘要

A system and method for computing flight time from an equi-distance point (EDP) to a reference point is disclosed. In one embodiment, a method of a flight management system (FMS) of an aircraft for computing flight time from an EDP to a reference point for an emergency landing of the aircraft includes receiving at least two reference points for landing the aircraft upon an occurrence of an emergency and determining a remaining flight path for the aircraft based on a current location of the aircraft and a flight plan serviced by the FMS. Further, the method includes generating the EDP for the aircraft by locating a point in the remaining flight path, and calculating an expected flight time of the aircraft from the EDP to each of the at least two reference points based on a plurality of factors affecting the flight time of the aircraft.
