In the aerospace industry, encoder applications combine demands for high-precision feedback along with the ability to operate in extreme environmental conditions.  Whether installed on airborne systems , ground support vehicles, testing fixtures, maintenance equipment, flight simulators or automated manufacturing machinery, rotary encoders are widely applied in aerospace. Encoders used in aerospace applications generally require housings and environmental ratings consistent with the presence of shock, vibration, and extreme temperatures.

The aerospace industry typically uses encoders to provide feedback for the following functions:
