How would this unit be calibrated? It seems that wear an aging on the motors and potentiometers would change their characteristics slightly over time.

- kens 4y agoI assume there is a detailed testing procedure specified by the FAA, and they would replace any bad components. But because of the servo loop feedback, most of the components aren't critical to accuracy. (Note that the internal power supplies are entirely unregulated.) If the motor slows down, for instance, it will still end up at the right location. The potentiometer is really the critical part, but it shouldn't change very much. And if it does change, as long as the resistance changes uniformly, it will still be okay.

This is an example of the pitot/static inspection procedure for a Cessna Citation Sovereign. The procedure itself begins on page 9 of the PDF.
