ABSTRACT:
A vane-type forward fuselage mounted angle of attack sensor having an internal force relief feature is disclosed. The sensor includes a cam surface having a first portion which defines a segment of a circle, a second portion which defines a curve with a decreasing radius and a shoulder portion between the first and second portions. A cam follower and spring biasing member act as a stop to limit the angular displacement of the vane and as an override to protect the vane against breakage and to automatically return the vane to an operational position after an override.
