Abstract

Using signals available into an Enhanced Ground Proximity Warning System (EGPWS), approach monitor systems and methods compare approach speed, approach angle and amount of tailwind/crosswind to the pre-selected envelopes. When the aircraft approach speed, approach angle, or tailwind/crosswind is greater than the pre-defined envelope, the approach monitor system generates an aural/visual advisory indicating the violation. The envelope is set as a function of “height above runway elevation”.

Claims

1. A method for advising of flying condition when an aircraft flies through approach gates, the method comprising:

a) automatically receiving one or more flight parameters at a first gate of a pair of predefined approach gates;

b) automatically determining if any of the one or more flight parameters are not in compliance with a corresponding predefined limit; and

c) automatically outputting an associated advisory if it was determined that one or more of the flight parameters was not in compliance with the corresponding predefined limit.

2. The method of claim 1, further comprising automatically repeating a)-c) at least one or more times before the aircraft reaches a second gate of the approach gates.

3. The method of claim 2, further comprising automatically outputting an unstable advisory if it was determined that one or more of the flight parameters is not in compliance with the corresponding predefined limit after the aircraft reaches a second gate of the approach gates.

4. The method of claim 3, wherein outputting at least one of the associated advisory or the unstable advisory comprises generating a speech signal based on the advisory and outputting the speech signal to one or more speakers.

5. The method of claim 3, wherein outputting at least one of the associated advisory or the unstable advisory comprises generating a visual presentation based on the type of advisory and outputting the visual presentation to one or more displays.

6. The method of claim 3, wherein the first gate is approximately 1,000 feet and the second approach gate is approximately 500 feet above at least one of an intended runway or a radio altimeter value.

7. The method of claim 1, wherein the one or more flight parameters include at least one of aircraft air speed, tailwind, crosswind, or aircraft approach angle.

8. The method of claim 1, further comprising checking position of landing gear and advising if the landing gear is not in a down position prior to approaching the first gate.

9. The method of claim 8, further comprising checking the position of the flaps and automatically advising if the flaps are not in a landing mode configuration at approximately the first gate.

10. A system on an aircraft for advising of flying condition when the aircraft flies through approach gates, the system comprising:

one or more components for producing one or more flight parameters at a first gate of a pair of predefined approach gates; and

a processing device in data communication with the one or more components for automatically receiving the one or more flight parameters, automatically determining if any of the one or more flight parameters are not in compliance with a corresponding predefined limit, and automatically outputting an associated advisory if it was determined that one or more of the flight parameters was not in compliance with the corresponding predefined limit.

11. The system of claim 10, wherein the processing device automatically repeats at least one or more times before the aircraft reaches a second gate of the approach gates.

12. The system of claim 11, wherein the processing device automatically outputs an unstable advisory if it was determined that one or more of the flight parameters is not in compliance with the corresponding predefined limit after the aircraft reaches a second gate of the approach gates.

13. The system of claim 12, further comprising one or more speakers in signal communication with the processing device, wherein the processing device generates a speech signal based on the advisory and outputs the speech signal to the one or more speakers.

14. The system of claim 12, further comprising one or more displays in signal communication with the processing device, wherein the processing device generates a visual presentation based on the type of advisory and outputs the visual presentation to one or more displays.

15. The system of claim 12, wherein the first gate is approximately 1,000 feet and the second approach gate is approximately 500 feet above at least one of an intended runway or a radio altimeter value.

16. The system of claim 10, wherein the one or more flight parameters include at least one of aircraft air speed, tailwind, crosswind, or aircraft approach angle.

17. The system of claim 10, wherein the processing device checks position of landing gear and produces an advisory if the landing gear is not in a down position prior to approaching the first gate.

18. The system of claim 17, wherein the processing device checks the position of the flaps and produces an advisory if the flaps are not in a landing mode configuration at approximately the first gate.
