Abstract

A system and method for braking an aircraft. A processor unit identifies an operating condition of the aircraft. The processor unit displays available modes indications on a display device on the aircraft. The available modes indications indicate modes of operating an automatic braking system on the aircraft that are available for selection by an operator based on the operating condition of the aircraft. The processor unit receives a mode selection from an operator interface. The mode selection indicates a selected mode of operating the automatic braking system that is selected by the operator from the available modes. The processor unit displays on the display device a selected mode indication indicating the selected mode.

First claim

What is claimed is:

1. A method of braking an aircraft, comprising:
identifying, by a processor unit, an operating condition of the aircraft;
displaying, by the processor unit on a display device on the aircraft, available modes indications indicating modes of operating an automatic braking system on the aircraft that are available for selection by an operator based on the operating condition of the aircraft;
receiving, by the processor unit from an operator interface, a mode selection indicating a selected mode of operating the automatic braking system that is selected by the operator from the available modes; and
displaying, by the processor unit on the display device, a selected mode indication indicating the selected mode.

2. The method of claim 1 , wherein the operator interface and the display device are on a flight deck of the aircraft.

3. The method of claim 1 , wherein the available modes are selected from a plurality of modes of operating the automatic braking system selected from the group of operating modes consisting of:
an off mode in which brakes will not be activated by the automatic braking system;
a rejected takeoff mode in which the brakes are activated automatically by the automatic braking system in response to a rejected takeoff;
a landing mode in which the brakes are activated automatically by the automatic braking system with a selectable level of braking following landing of the aircraft on a runway and before the aircraft leaves the runway following the landing of the aircraft on the runway;
a brake to exit mode in which the brakes are activated automatically by the automatic braking system following the landing of the aircraft to slow the aircraft to no more than a target speed when the aircraft reaches a designated point following the landing of the aircraft; and
a collision avoidance mode in which the brakes are activated automatically by the automatic braking system when the aircraft is moving on ground and a possible collision of the aircraft is detected.

4. The method of claim 3 , wherein the collision avoidance mode is activated when the rejected takeoff mode is the selected mode or when the landing mode is the selected mode or when the brake to exit mode is the selected mode.

5. The method of claim 1 , wherein the operator interface comprises a mechanical device that is moveable by the operator to select the selected mode from the available modes.

6. The method of claim 1 , wherein the operator interface comprises a graphical user interface displayed on the display device and comprising the available modes indications.

7. The method of claim 1 , wherein displaying the available modes indications based on the operating condition of the aircraft comprises displaying the available modes indications in a first color when the aircraft is in a first operating condition and displaying the available modes indications in a second color that is different from the first color when the aircraft is in a second operating condition that is different from the first operating condition.

8. The method of claim 1 further comprising:
stopping displaying, on the display device, the available modes indications and the selected mode indication in response to a determination that the selected mode is an off mode for more than a selected duration; and
resuming displaying, on the display device, the available modes indications and the selected mode indication in response to a change in the selected mode received from the operator interface or a determination that the operating condition of the aircraft has changed.

9. The method of claim 1 further comprising:
controlling braking of the aircraft by the automatic braking system based on the selected mode; and
displaying by the processor unit on the display device an automatic braking active indication to indicate when brakes are activated by the automatic braking system.

10. A system, comprising:
an operator interface; and
a display generator configured to display, on a display device on an aircraft, available modes indications indicating available modes of operating an automatic braking system on the aircraft that are available for selection by an operator based on an operating condition of the aircraft and a selected mode indication indicating a selected mode of operating the automatic braking system that is selected by the operator from the available modes using the operator interface.

11. The system of claim 10 , wherein the operator interface and the display device are on a flight deck of the aircraft.

12. The system of claim 10 , wherein the available modes are selected from a plurality of modes of operating the automatic braking system selected from the group of operating modes consisting of:
an off mode in which brakes will not be activated by the automatic braking system;
a rejected takeoff mode in which the brakes are activated automatically by the automatic braking system in response to a rejected takeoff;
a landing mode in which the brakes are activated automatically by the automatic braking system with a selectable level of braking following landing of the aircraft on a runway and before the aircraft leaves the runway following the landing of the aircraft on the runway;
a brake to exit mode in which the brakes are activated automatically by the automatic braking system following the landing of the aircraft to slow the aircraft to no more than a target speed when the aircraft reaches a designated point following the landing of the aircraft; and
a collision avoidance mode in which the brakes are activated automatically by the automatic braking system when the aircraft is moving on ground and a possible collision of the aircraft is detected.

13. The system of claim 12 , wherein the collision avoidance mode is activated when the rejected takeoff mode is the selected mode or when the landing mode is the selected mode or when the brake to exit mode is the selected mode.

14. The system of claim 10 , wherein the operator interface comprises a mechanical device that is moveable by the operator to select the selected mode from the available modes.

15. The system of claim 10 , wherein the operator interface comprises a graphical user interface generated by the display generator, displayed on the display device, and comprising the available modes indications.

16. The system of claim 10 , wherein the display generator is configured to display the available modes indications in a first color when the aircraft is in a first operating condition and display the available modes indications in a second color that is different from the first color when the aircraft is in a second operating condition that is different from the first operating condition.

17. The system of claim 10 , wherein the display generator is further configured to:
stop displaying, on the display device, the available modes indications and the selected mode indication in response to a determination that the selected mode is an off mode for more than a selected duration; and
resume displaying, on the display device, the available modes indications and the selected mode indication in response to a change in the selected mode received from the operator interface or a determination that the operating condition of the aircraft has changed.

18. The system of claim 10 further comprising:
an automatic braking system controller configured to receive from the operator interface a mode selection indicating the selected mode of operating the automatic braking system and to control braking of the aircraft by the automatic br
