Sequencing, merging and approach-spacing systems and methods

1. An aircraft control system for a host aircraft, the system comprising:

a processor for executing one or more instructions that implement one or more functions of the aircraft control system;

a transceiver for transmitting information from and receiving information for the host aircraft;

a display; and

memory for storing the one or more instructions for execution by the processor to implement the one or more functions of the aircraft control system to:

receive from the transceiver information from another aircraft;

determine whether the host aircraft and the other aircraft are within a predefined range of a location where the host aircraft and the other aircraft plan to land; and

when the host aircraft and the other aircraft are within the predefined range of the location where the host aircraft and the other aircraft plan to land, generate from the received information a signal for use in the host aircraft to control separation between the host aircraft and the other aircraft while the host aircraft and the other aircraft are within the predefined range of the location where the host aircraft and the other aircraft plan to land, wherein controlling the separation between the host aircraft and the other aircraft includes maintaining a spacing interval between the host aircraft and the other aircraft and wherein the signal is used to indicate on the display a position of where the host aircraft should be relative to the other aircraft to control separation between the host aircraft and the other aircraft.

2. The aircraft control system of claim 1 wherein the information received from the other aircraft comprises one or more of position data and velocity data of the other aircraft.

3. The aircraft control system of claim 1 wherein the information received from the other aircraft comprises Automatic Dependant Surveillance—Broadcast (ADS-B) aircraft state data for the other aircraft.

4. The aircraft control system of claim 1 wherein the generation of the signal is also based on aircraft state data for the host aircraft.

5. The aircraft control system of claim 4 wherein the aircraft state data for the host aircraft comprises one or more of position data and velocity data of the host aircraft.

6. The aircraft control system of claim 1 wherein the signal is used to generate a command for use by the host aircraft to control separation between the host aircraft and the other aircraft.

7. The aircraft control system of claim 1 wherein the separation comprises a range between the host aircraft and the other aircraft.

8. The aircraft control system of claim 1 wherein the separation comprises a time until a range between the host aircraft and the other aircraft is closed to a predefined limit at a specified rate of closure.

9. The aircraft control system of claim 6 wherein the command comprises a speed command for use by the host aircraft to control separation between the host aircraft and the other aircraft.

10. The aircraft control system of claim 9 wherein the speed command is employed by one of a manual speed adjustment and an automatic speed adjustment.

11. The aircraft control system of claim 1 wherein the transceiver comprises a separate receiver and a separate transmitter.

12. A method of operating an aircraft control system for a host aircraft, the method comprising:

receiving on the host aircraft information from another aircraft;

determining whether the host aircraft and the other aircraft are within a predefined range of a location where the host aircraft and the other aircraft plan to land; and

when the host aircraft and the other aircraft are within the predefined range of the location where the host aircraft and the other aircraft plan to land, generating from the received information a signal for use in the host aircraft to control separation between the host aircraft and the other aircraft while the aircraft are within the predefined range of the location where the host aircraft and the other aircraft plan to land, wherein controlling the separation between the host aircraft and the other aircraft includes maintaining a spacing interval between the host aircraft and the other aircraft and wherein the signal is used to indicate on the display a position of where the host aircraft should be relative to the other aircraft to control separation between the host aircraft and the other aircraft.

13. The method of claim 12 wherein the information received from the other aircraft comprises one or more of position data and velocity data of the other aircraft.

14. The method of claim 12 wherein the information received from the other aircraft comprises Automatic Dependant Surveillance—Broadcast (ADS-B) aircraft state data for the other aircraft.

15. The method of claim 12 wherein the generation of the signal is also based on aircraft state data for the host aircraft.

16. The method of claim 15 wherein the aircraft state data for the host aircraft comprises one or more of position data and velocity data of the host aircraft.

17. The method of claim 12 wherein the signal is used to generate a command for use by the host aircraft to control separation between the host aircraft and the other aircraft.

18. The method of claim 12 wherein the separation comprises a range between the host aircraft and the other aircraft.

19. The method of claim 12 wherein the separation comprises a time until a range between the host aircraft and the other aircraft is closed to a predefined limit at a specified rate of closure.

20. The method of claim 17 wherein the command comprises a speed command for use by the host aircraft to control separation between the host aircraft and the other aircraft.

21. The method of claim 20 wherein the speed command is employed by one of a manual speed adjustment and an automatic speed adjustment.

22. The method of claim 12 further comprising a transceiver for transmitting information from and receiving information for the host aircraft, wherein the transceiver comprises a separate receiver and a separate transmitter.
