A system and method for selectively alerting a pilot of an aircraft about distance remaining to the end of a runway. A position of the aircraft is received. A position of a runway is retrieved from a runway database. The retrieved position of the runway is compared to the received position of the aircraft to determine if the aircraft is within an alert envelope relative to the retrieved position of the runway. The position of the runway is subtracted from the position of the aircraft to determine a distance to the distal end of the runway. An alert to the pilot is generated based upon the distance to the distal end of the runway.

1. A method for alerting a pilot of an aircraft about runway distance remaining, the method comprising: receiving a position of the aircraft;comparing altitude of the aircraft to a predefined altitude limit;comparing a previously stored runway information to the received position of the aircraft;determine if the aircraft is within an alert envelope based on the comparisons;determining a runway distance remaining, if the aircraft is determined to be within the alert envelope; andgenerating an alert to the pilot based upon the runway distance remaining,wherein the alert identifies runway distance remaining. 2. The method of claim 1, wherein the predefined altitude limit is a height above runway value. 3. The method of claim 1, wherein generating the alert includes generating an aural warning. 4. The method of claim 3, wherein the aural warning includes words describing the runway distance remaining. 5. The method of claim 1, wherein generating the alert includes generating a visual warning on a display. 6. The method of claim 5, wherein the visual warning includes of one of words, figures, and graphic indicators describing the runway distance remaining. 7. A system for generating an alert to the pilot of an aircraft about runway distance remaining, the system comprising: a database comprising runway information;a position sensor configured to produce aircraft position and altitude information;a processor in data communication with the database and the position sensor, the processor comprising: an input processing buffer configured to receive the aircraft position and altitude information and runway information;an advisory condition detection component configured to determine whether the aircraft is within an advisory envelope based upon received the aircraft position and altitude information, runway information, and a predefined altitude limit; anda component configured to determine runway distance remaining, if the aircraft is determined to be within the alert envelope and to generate an alert to the pilot based upon the distance to the distal end of the runway;an output device configured to output the generated alert,wherein the alert identifies runway distance remaining. 8. The system of claim 7, wherein the predefined altitude limit is a height above runway value. 9. The system of claim 7, wherein the output device is an aural output device. 10. The system of claim 9, wherein the alert includes words describing the runway distance remaining. 11. The system of claim 7, wherein the output device is a display. 12. The system of claim 11, wherein the alert includes of one of words, figures, and graphic indicators describing the runway distance remaining.
