Abstract

A system and method for an aircraft alerts a user of the aircraft of a possible entrance into a selected airspace. A flight path of an aircraft and locations of a plurality of selected airspaces are stored on at least one storage medium. A processor is in operable communication with the at least one storage device and configured to compare the flight path of the aircraft to the locations of the plurality of selected airspaces and provide an alert signal if the flight path calls for the aircraft to operate within a pre-selected distance of at least one of the plurality of selected airspaces.

Claims

1. An avionics system comprising:

at least one storage device having a flight path of an aircraft and locations of a plurality of selected airspaces stored thereon; and

a processor in operable communication with the at least one storage device, the processor being configured to;

compare the flight path of the aircraft to the locations of the plurality of selected airspaces; and

provide an alert signal if the flight path calls for the aircraft to operate within a pre-selected distance of at least one of the plurality of selected airspaces.

2. The system of claim 1, wherein the flight path comprises at least one of a latitude and longitude of the aircraft, a heading of the aircraft, and an altitude of the aircraft and the locations of the plurality of selected airspaces comprise for each selected airspace at least one of a latitude and longitude and an altitude.

3. The system of claim 2, wherein the at least one storage device comprises a Flight Management System (FMS).

4. The system of claim 3, wherein the plurality of selected airspaces comprise at least one of an airspace defined by a user and an airspace defined by an aviation regulatory authority.

5. The system of claim 4, wherein said calling of the operation of the aircraft within the pre-selected distance occurs when the flight path calls for the aircraft to enter at least one of the plurality of selected airspaces.

6. The system of claim 5, wherein said providing of the alert signal occurs when a current heading of the aircraft does not intersect a nearest one of the plurality of selected airspaces.

7. The system of claim 6, wherein said providing of the alert signal occurs when the aircraft is not in flight.

8. The system of claim 7, wherein at least some of the plurality of selected airspaces are at least one of a Flight Information Region (FIR), an Upper Flight Information Region (UIR), and a Military Operating Area (MOA).

9. The system of claim 8, further comprising a visual display device in operable communication with the processor to receive the alert signal and generate a visual indication of the alert signal, the visual indication comprising at least one of a color-coded message and a text message.

10. The system of claim 9, further comprising an audio device in operable communication with the processor to receive the alert signal and generate an audio indication of the alert signal.

11. An avionics system comprising:

a Flight Management System (FMS) having a flight path of an aircraft stored thereon;

a computer-readable medium in operable communication with the FMS having locations of a plurality of selected airspaces stored thereon;

a processor in operable communication with the FMS and the computer-readable medium, the processor being configured to;

compare the flight path of the aircraft to the locations of the plurality of selected airspaces; and

provide an alert signal if the flight path calls for the aircraft enter at least one of the plurality of selected airspaces; and

at least one of a visual display device in operable communication with the processor to receive the alert signal and generate a visual indication of the alert signal and an audio device in operable communication with the processor to receive the alert signal and generate an audio indication of the alert signal.

12. The system of claim 11, wherein said providing of the alert signal occurs when at least one of a current heading of the aircraft does not intersect a nearest one of the plurality of selected airspaces and the aircraft is not in flight.

13. The system of claim 12, wherein the at least one of a visual display device and an audio device comprises the visual display device and wherein the visual indication comprises at least one of a color-coded message and a text message.

14. The system of claim 13, wherein the visual display device is connected to the FMS.

15. The system of claim 14, wherein at least some of the plurality of selected airspaces are at least one of a Flight Information Region (FIR), an Upper Flight Information Region (UIR), and a Military Operating Area (MOA).

19. The method of claim 13, wherein the plurality of airspaces comprises at least one of an airspace defined by the user and an airspace defined by an aviation regulatory authority.

20. The method of claim 19, wherein said alerting of the user comprises providing at least one of a visual indication and an audio indication to the user of the aircraft.

16. A method for alerting a user of an aircraft of a possible entrance into a selected airspace comprising:

loading a flight path onto a Flight Management System (FMS) onboard the aircraft;

comparing the flight path to locations of a plurality of selected airspaces stored on a computer-readable medium in operable communication with the FMS; and

alerting the user of the aircraft if the flight path calls for the aircraft to intersect one or more of the plurality of selected airspaces.

17. The method of claim 16, wherein the flight path comprises at least one of latitude and longitude of the aircraft, a heading of the aircraft, and an altitude of the aircraft and the locations of the plurality of selected airspaces comprises at least one of the latitude and longitude of the selected airspaces and an altitude of the selected airspaces.

18. The method of claim 17, wherein said alerting of the user occurs when at least one of a current heading of the aircraft does not intersect a nearest one of the plurality of selected airspaces and the aircraft is not in flight.
