a proximity sensor disposed at said housing for detecting movement of said paddle at a sensing area.
2. The stall indicator of claim 1 wherein the paddle is in a first position with respective to the sensing area under normal air flow conditions and movable to a second position with respect to the sensing area as the air flow approaches a stall condition.
3. The stall indicator of claim 2 wherein the proximity sensor detects the first and second positions of the paddle by electrical energy at the sensing area to generate first and second signals when the paddle is in the first and second positions, respectively.
4. The stall indicator of claim 3 wherein the proximity sensor comprises an inductive circuit for generating an electromagnetic field in the vicinity of the sensing area for detecting the first and second positions of the paddle.
5. The stall indicator of claim 3 wherein the proximity sensor comprises a capacitive circuit for generating an electrostatic field in the vicinity of the sensing area for detecting the first and second positions of the paddle.
6. The stall indicator of claim 3 wherein the proximity sensor comprises a solid-state switch for generating the first and second signals when the paddle is in the first and second positions, respectively.
7. The stall indicator of claim 6 wherein the solid-state switch generates the first and second signals through conduction and non-conduction states.
8. The stall indicator of claim 3 wherein the paddle comprises electrically conductive material.
9. The stall indicator of claim 2 wherein one end of the paddle is pivotably hinged to a surface of the housing and another end is disposed to extend beyond said wing a predetermined distance, said paddle movable with respect to said housing surface in response to air flow at said wing; and wherein the paddle is in the first position when close to the surface of the housing and is in the second position when away from the surface of the housing.
10. The stall indicator of claim 9 wherein the paddle is in the first position when at rest.
11. The stall indicator of claim 9 wherein the sensing area is in the vicinity of the housing surface.
12. The stall indicator of claim 1 wherein the structure is configurable to fit a curved surface of the leading edge of the wing and adjustable at said wing surface to render movement of the paddle with movement of a stagnation point.
13. The stall indicator of claim 1 wherein the proximity sensor is disposed within the housing and the housing is sealed.
14. The stall indicator of claim 1 wherein the housing comprises electrically non-conductive material.
15. The stall indicator of claim 1 wherein the paddle is in a rest position with respective to the sensing area under normal air flow conditions and movable variably to new positions with respect to the sensing area as the air flow approaches a stall condition; and wherein the proximity sensor detects the new positions of the paddle by electrical energy at the sensing area to generate a variable signal in proportion to the movement of the paddle away from the rest position.
16. A method of indicating when an aircraft is approaching a stall condition, said method comprising the steps of:
permitting a paddle, disposed at a leading edge of a wing of the aircraft, movement with respect to a sensing area in response to air flow at said wing;
detecting movement of said paddle by proximity sensing with electrical energy in the vicinity of the sensing area; and
effecting an electrical signal representative of said detected movement of said paddle, which signal being indicative of an approaching stall condition at said wing.
17. The method of claim 16 wherein the step of detecting includes generating electrical energy in the form of an electromagnetic field in the vicinity of the sensing area for detecting the movement of the paddle.
18. The method of claim 16 wherein the step of detecting includes generating electrical energy in the form of an electrostatic field in the vicinity of the sensing area for detecting the movement of the paddle.
19. The method of claim 16 wherein the step of detecting includes the steps of: affecting a change in the electrical energy by the movement of the paddle; and detecting a position of the paddle based on the affected change in electrical energy.
20. The method of claim 19 wherein the change in electrical energy is affected by an electrically conductive paddle.
21. The method of claim 16 wherein the electrical signal is effected through one of a conduction state and non-conduction state of a solid-state switch.
22. The method of claim 16 wherein the step of permitting includes the step of positioning the paddle at the leading edge of the wing to cause movement thereof is response to a changing position of a stagnation point.
