First Claim
Patent Images
1. A method for automatically selecting a waypoint for a flight plan for an aircraft from at least two similarly identified waypoints, the method comprising the steps of:
- a) determining a distance to each of the waypoints from the at least two waypoints from a chosen position;
b) determining a condition of the aircraft;
c) providing the flight plan; and
d) calculating the selected waypoint based on steps a), b) and c).

Abstract
A system is used to determine which entry in the NDB should be chosen for similarly named identifiers. It first tries to use waypoints before the ambiguous name to determine which entry to use. If those are not available, the present system will use the aircraft'"'"'s current position, or, if the aircraft is on the ground, the origin airport as determinative factors. These factors will take into account not having the aircraft'"'"'s location, when the ambiguous waypoint is to be inserted into the route, and if the waypoint is an airway entry or exit.

9. An apparatus for automatically selecting a waypoint for a flight plan for an aircraft from at least two similarly identified waypoints, the apparatus comprising:
-
a means for measuring a distance to each of the waypoints from the at least two waypoints from a chosen position;
a storage means for storing measured distances in the means for measuring, a condition of the aircraft and the flight plan; and
a means for calculating the selected waypoint based on data in the storage means.
