Abstract

A system and method are provided for supplying haptic feedback to, and for electronically linking, pilot and co-pilot user interfaces. The user interface haptic feedback and linking are implemented using either force or position data. If the force or position data become unavailable, then position or force data, respectively, are used to implement the user interface haptic feedback and linking.
