Abstract

An integrated side stick controller combines air speed, turning and altitude changing rate control into one pilot input control device. Movements of the integrated side stick controller will perform manipulations on aircraft surfaces devices in order to maneuver the aircraft. For instance, fore and aft movement of the side stick will increase/decrease the air speed, left/right movements of the side stick will control the turning of the aircraft, and up/down movements of the slider on the side stick will change the ascend/descend rate of the aircraft.

Claims

1. An integrated pilot input device for use by a pilot to provide signals to an aircraft control system, the integrated pilot input device comprising:

a stick with two degrees of movement and adapted to provide output signals to the aircraft control system to control air speed when the stick is moved fore and aft and to turn the aircraft when the stick is moved left and right;

a knob positioned on the stick, and having a plurality of positions, that provides output signals to the aircraft control system to control the ascend and descend rate of the aircraft according to a position of the knob.

2. The integrated pilot input device of claim 1 wherein the stick includes a bias mechanism to return the side stick to a left and right reference position when released by the pilot.

3. The integrated pilot input device of claim 2, wherein the stick is adapted to remain in its current fore and aft position, when released by the pilot, to maintain an airspeed.

4. The integrated pilot input device of claim 1 wherein the knob includes an indicator that references a knob position which corresponds to level flight of the aircraft.

5. The integrated pilot input device of claim 4 wherein the indicator is a detent providing tactical feedback to the plot.

6. An aircraft control device configured to control aircraft air speed, turning, and altitude change rate, the device comprising:

positioning apparatus adapted to permit movement of a control member in a forward or backward position and to secure the control member in place when the control member is released by a pilot;

sensing apparatus adapted to detect a forward or backward position of the control member and to send a signal indicating an increase or decrease in aircraft speed based on the detected forward or backward position of the control member; and

an input apparatus integrated into the control member and adapted to receive input from the pilot for rate of aircraft climbing or descending.

7. The device of claim 6, wherein the positioning apparatus is further adapted to permit movement of the control member in a left or right position and to return the control member to a central reference position from a left or right position.

8. The device of claim 7, wherein the sensing apparatus is further adapted to detect a left or right position of the control member and to send a signal indicating a left or right movement in the aircraft based on the detected left or right position of the control member.

9. The device of claim 7, wherein the central reference position corresponds to a straight and level position of flight.

10. The device of claim 7, wherein the positioning apparatus comprises a positional biasing device.

11. The device of claim 6, wherein the input apparatus is a knob having incremental positions.

12. The device of claim 6, wherein the input apparatus comprises a range of altitude change rate positions.

13. The device of claim 6, wherein the control member is a joystick.

14. An aircraft control device having control for aircraft speed and position, the control device comprising:

a joystick configured with two axes of movement, the two axes of movement being forward/backward and left/right, the forward/backward axis being configured to control aircraft air speed and the left/right axis being configured to control aircraft direction; and

an input apparatus coupled to the joystick and being configured to receive input to control aircraft altitude.

15. The control device of claim 14, wherein the joystick is coupled to a number of mechanical apparatus in a fly-by-cable system.

16. The control device of claim 14, wherein the joystick is coupled to electrical controls in a fly-by-wire system.

17. The control device of claim 14, wherein the input apparatus is a rotatable knob.

18. The control device of claim 17, wherein the input apparatus includes incremental positions.

19. The control device of claim 18, wherein the incremental positions correspond to levels of flight.

20. The control device of claim 14, wherein the input apparatus is a rotatable member for selecting a level of flight.
