Disclosed is a system and method for diverting from a flight plan without adjusting an autopilot by treating a heading change as the new leg of a flight plan. The present invention allows the pilot of an aircraft to enter a heading to follow into a flight management system, which treats the heading as the current leg of a flight plan otherwise being followed by the flight management system. The present invention graphically displays the heading leg as the predicted track so that the pilot is able to see the airplane's expected path. Such a change allows the autopilot to continue following commands from the flight management system rather than being changed to a mode in which the autopilot follows heading commands directly from the pilot.

Entering an identifier to select a navigational waypoint requires 'head-down' time, resulting in less time for operating a vehicle. Accordingly, a technique for selecting a navigational waypoint for use is provided. The present invention includes receiving a partially entered identifier identifying, in part, a navigational waypoint for use, searching for the navigational waypoint for use from amongst a plurality of identifiers using the partially entered identifier and a search criterion other than a criterion based on a pre-existing ordering of the plurality of identifiers, and completing the partially entered waypoint identifier based on results from the searching. The completed waypoint identifier forms a user-selectable navigational waypoint for use. The present invention uses as a search criterion a geographical relationship between a location of each identifier of the plurality and a reference location/area to reduce the number of user-entered characters needed to select a navigational waypoint, thereby reducing 'head-down' time.
