Abstract

Selector lever systems of aircraft are provided. The selector lever systems include a selector lever configured to control operation of one or more aircraft control surfaces, the selector lever having a handle configured to enable manual operation of the selector lever, a touch sensor arranged on the handle, and a controller arranged in communication with the touch sensor, the controller configured to at least one of generate a notification when a signal is received from the touch sensor and unlock the selector lever from a locked state.

First claim

What is claimed is:

1. A selector lever system of an aircraft, the selector lever system comprising:
a selector lever configured to control operation of one or more aircraft control surfaces, the selector lever having a handle configured to enable manual operation of the selector lever;
a touch sensor arranged on the handle, wherein the touch sensor is configured to detect the presence of a hand of a user placed on the touch sensor, and the touch sensor is configured to generate a signal indicating the presence of a hand of a user on the handle; and
a controller arranged in communication with the touch sensor, the controller configured to at least one of generate a notification associated with the selector lever when the signal is received from the touch sensor and unlock the selector lever from a locked state when the signal is received from the touch sensor.

2. The selector lever system according to claim 1 , wherein the touch sensor is located on at least one of a top surface and a side surface of the handle.

3. The selector lever system according to claim 1 , wherein the notification is at least one of an auditory announcement and a visual display indicating a position of at least one of the selector lever and the one or more aircraft control surfaces.

4. The selector lever system according to claim 1 , wherein the controller is part of a flight computer of the aircraft.

5. The selector lever system according to claim 1 , wherein the touch sensor is one of a capacitive touch-sensor, an inductive touch-sensor, and a pressure touch-sensor.

6. The selector lever system according to claim 1 , wherein the selector lever comprises a housing and a shaft, wherein the handle is disposed on an end of the shaft.

7. The selector lever system according to claim 1 , further comprising a software locking mechanism configured to prevent movement of the one or more control surfaces in response to movement of the selector lever until a predetermined touch is detected at the touch sensor.

8. The selector lever system according to claim 7 , wherein the predetermined touch is at least one of a contact of a predetermined duration and a predetermined pressure.

9. The selector lever system according to claim 1 , further comprising a locking mechanism configured to lock the selector lever in a locked state until a predetermined touch is detected at the touch sensor.

10. The selector lever system according to claim 9 , wherein the locking mechanism is at least one of electromechanical and electromagnetic.

11. The selector lever system according to claim 9 , wherein the locking mechanism is arranged to engage with at least one of a collar and a shaft of the selector lever.

12. The selector lever system according to claim 9 , wherein the predetermined touch is at least one of a contact of a predetermined duration and a predetermined pressure.

13. A method of controlling a selector lever of an aircraft, the method comprising:
detecting a predetermined contact with a touch sensor on a handle of the selector lever, the selector lever configured to control operation of one or more aircraft control surfaces, wherein the touch sensor is configured to detect the presence of a hand of a user placed on the touch sensor, and the touch sensor is configured to generate a signal indicating the presence of a hand of a user on the handle; and
at least one of generating a notification associated with the selector lever in response to the detected predetermined contact and unlocking the selector lever from a locked state in response to the detected predetermined contact.

14. The method of claim 13 , wherein the notification is at least one of an auditory announcement and a visual display indicating a position of at least one of the selector lever and the one or more aircraft control surfaces.

15. The method according to claim 13 , wherein the detection is performed by a controller operably connected to the touch sensor.

16. The method according to claim 13 , wherein the touch sensor is one of a capacitive touch-sensor, an inductive touch-sensor, and a pressure touch-sensor.

17. The method according to claim 13 , wherein a shaft of the selector lever is moveable along a detent system, and wherein the notification comprises an indication of a detent position of the shaft.

18. The method according to claim 13 , further comprising a software locking mechanism configured to prevent movement of the one or more control surfaces in response to movement of the selector lever until the predetermined contact is detected at the touch sensor.

19. The method according to claim 13 , wherein the selector lever comprises a locking mechanism configured to lock the selector lever in a locked state until the predetermined contact is detected at the touch sensor.

20. The method according to claim 19 , wherein the locking mechanism is arranged to engage with at least one of a collar and a shaft of the selector lever.
