Abstract
An angle of attack sensing system includes a rotatable vane, a first pressure sensing port, a second pressure sensing port, a vane position sensor, and a fault detector. The rotatable vane includes a first surface and a second surface opposite the first surface. The first pressure sensing port is disposed in the first surface. The second pressure sensing port is disposed in the second surface. The vane position sensor is configured to output a rotational position signal of the rotatable vane. The fault detector is configured to output an indication of a rotational fault condition based on a difference between a first sensed pressure from the first pressure sensing port and a second sensed pressure from the second pressure sensing port.
