1. A method for determining when an aircraft is headed in the right direction on a runway entered upon at a location that does not display runway identification, comprising:
- receiving runway data;
receiving aircraft position data;
determining the identity of the runway from the runway data and the aircraft position data; and
comparing the identity of the runway with a representation of an assigned runway stored on the aircraft to determine that they match;
retrieving a balanced field length;
determining the remaining runway distance from the runway data and the position data;
displaying the remaining runway distance in a first manner when the remaining runway distance is greater that the balanced field length; and
displaying the remaining runway distance in a second manner when the remaining runway distance is less than the balanced field length.

Abstract
A system and method for determining if an aircraft is headed in the right direction on a runway entered upon at a location that does not display runway identification comprises receiving runway and aircraft position data for determining the identity of the runway. The identity of the runway is then compared with a representation of an assigned runway stored on the aircraft to determine that they match.

16. A system for determining when an aircraft is headed in the right direction on a runway entered upon at a location that does not display runway identification, comprising:
-
a first source of runway data; a second source of aircraft position data; and a processor coupled to the first and second sources and configured to (1) determine the identity of the runway from the runway data and the aircraft position data; and
(2) compare the identity of the runway with a representation of an assigned runway stored on the aircraft to determine when they match;
(3) retrieve a balanced field length;
(4) determine the remaining runway distance from the runway data and the position data;
(5) display the remaining runway distance in a first manner when the remaining runway distance is greater that the balanced field length; and
(6) display the remaining runway distance in a second manner when the remaining runway distance is less than the balanced field length.
