SYSTEM AND METHOD FOR COMPUTING AN EQUI-TIME POINT FOR AIRCRAFTS
First Claim
1. 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 at least two reference points for landing the aircraft upon an occurrence of an emergency;
determining 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 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.

Abstract
A system and method for generating an equi-time point (ETP) for an emergency landing of an aircraft are disclosed. In one aspect, a method of a flight management system (FMS) of an aircraft for generating an ETP for an emergency landing of the aircraft includes receiving at least two reference points for landing the aircraft upon an occurrence of an emergency. The method also includes determining an equi-distance point (EDP) for the aircraft by locating a first point on the remaining flight path of the aircraft which is equidistant from the at least two reference points. The method further includes generating an ETP for the aircraft by locating a second point on the remaining flight path such that 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.
