Patent ID: 6880258

Claim:
An inclinometer for measuring the angle between a reference angular position and an angularly adjustable surface of a portion of a wing of an aircraft, said wing having a leading edge and a trailing edge, said inclinometer comprising: a pair of accelerometers for sensing the gravitational vector of the earth and for providing an output signal from each accelerometer; centering devices for referencing the accelerometers to the leading and trailing edges a portion of the wing of the aircraft; a data processor for receiving the output signals from the pair of accelerometers to determine a first reference position of the adjustable surface of the wing, to determine a second adjusted position of the adjustable surface of the wing and to determine an angle between the first reference position and the second adjusted position; and a display for receiving information from the data processor and for displaying the angle of the adjustable surface of the wing as determined by the data processor.
