1. A method of detecting a pitch rate sensor fault comprising the steps of:

  • utilizing a kinematic relationship of a plurality of sensor signals other than a signal from a pitch rate sensor to generate a reference pitch angle;

    adjusting a pitch rate sensor signal for a plurality of valid signal biases toward a compensated pitch rate sensor signal;

    comparing the reference pitch angle and the compensated pitch rate to identify a suspected pitch rate sensor fault; and

    verifying a plurality of predetermined parameters in relation to the suspected pitch rate sensor fault to confirm the suspected pitch rate sensor fault to be an actual fault.
