Patent ID: 8467916

Claim:
A method of a flight management system (FMS) of an aircraft for generating an equi-time point (ETP) for an emergency landing of the aircraft, comprising: receiving, by a processor, at least two reference points for landing the aircraft upon an occurrence of an emergency; determining, by the processor, an equi-distance point (EDP) for the aircraft by locating a first point on a remaining flight path of the aircraft which is equidistant from the at least two reference points; and generating, by the processor, an equi-time point (ETP) for the aircraft by locating a second point on the remaining flight path of the aircraft, wherein a time difference between any two of expected flight times of the aircraft from the second point to the at least two reference points is less than a threshold value, and wherein an approximation of the second point is initially based on the equi-distance point.
