Abstract

An aircraft on-board system for communicating with a ground-based radio transmitter forming a part of a Local Area Augmentation System for aiding in the navigation and landing of the aircraft, comprising a radio receiver adapted to receive signals, including identification signals identifying the Local Area Augmentation System, from the ground-based radio transmitter, a controller coupled to the radio receiver having an entry device for entering the channel number of a desired ground-based radio station and for tuning the on-board radio receiver to a desired frequency and further receiving from the radio signals, including the identification signals, and further having a signaling mechanism for providing to an operator of the aircraft on-board system a message including the identification of the ground-based radio station.

Claims

1. An aircraft on-board system for communicating with a ground-based radio transmitter forming a part of a Local Area Augmentation System for aiding in the navigation and landing of the aircraft, comprising:

a radio receiver adapted to receive signals, including identification signals identifying the Local Area Augmentation System, from the ground-based radio transmitter,

a controller coupled to the radio receiver comprising an entry device for entering a channel number of a desired ground-based radio station and for timing the on-board radio receiver to a desired frequency,

the controller receiving identification signals from the radio receiver, and

an output device connected to the controller for providing to an operator of the aircraft on-board system a message including the channel number of the ground-based radio station.

2. The aircraft on-board system as set forth in claim 1 wherein the output device is a display connected to the controller.

3. The aircraft on-board system as set forth in claim 2 wherein the identification signals further include the identity of a runway with which the LAAS is associated.

4. The aircraft on-board system as set forth in claim 3 wherein the display identifies the runway with which the LAAS is associated.

5. The aircraft on-board system as set forth in claim 1 wherein the output device produces an aural signal.

6. The aircraft on-board system as set forth in claim 5 wherein the identification signals further include the identity of a runway with which the LAAS is associated.

7. The aircraft on-board system as set forth in claim 6 wherein the aural signal identifies the runway with which the LAAS is associated.

15. The aircraft on board system as set forth in claim 5 wherein the aural signal identifies the runway with which the LAAS is associated using Morse code.

8. In an aircraft on-board system for communicating with a ground-based radio transmitter forming a pert of a Local Area Augmentation System for aiding in the navigation and landing of the aircraft, the on-board system comprising a radio receiver and a controller coupled to the radio receiver, the controller comprising an entry device for entering the channel number of a desired ground-based radio station and for tuning the radio receiver to a desired frequency the controller further comprising an output device for providing to an operator of the aircraft on-board system a message including the identification of the ground-based radio station, the method comprising:

receiving a channel number of a ground-based radio station;

tuning the radio receiver to the frequency of the channel number;

receiving identification signals, including the channel number of the ground based station, from the ground based station; and

displaying the channel number received from the ground based receiver at the output device.

9. The method as set forth in claim 8 wherein the output device is a visual display connected to the controller.

10. The method as set forth in claim 8 wherein the identification signals further identify a runway with which the LAAS is associated.

11. The method as set forth in claim 10 wherein the visual display identifies the runway with which the LAAS is associated.

12. The method as set forth in claim 8 wherein the output device produces an aural signal.

13. The method as set forth in claim 12 wherein the identification signals further identify a runway with which the LAAS is associated.

14. The method as set forth in claim 13 wherein the aural signal identifies the runway with which the LAAS is associated.

16. The method is set forth in claim 12 wherein the aural signal identifies the frequency of the ground-based radio transmitter using Morse code.
