ABSTRACT:
Methods, apparatus and program product are provided to obtain a shortened holding pattern exit path for an aircraft from its current position (CP) in or entering a holding pattern to an allowed exit point (EP) of the holding pattern. The flight management system (FMS) determines which segment of the holding pattern the aircraft is currently on, i.e., A, B, or C defines in terms of the holding pattern turn points (TP1, TP2, TP3, TP4) and the waypoint (SP) which is symmetrical to the desired EP. The FMS compares the aircraft CP with EP and SP location and directs turns at the appropriate waypoints to give the shortest allowed exit pathway. Both Type I and Type II holding pattern entries are accommodated.
