Pitot tube diagnostic systems and methods

摘要

A pitot tube diagnostic system including a data acquisition unit to acquire an output signal of a pitot-static system, the output signal having a static component and a dynamic component, and a processing unit to monitor the dynamic component for one or more characteristics that deviate from one or more predetermined reference characteristics to indicate impairment of the pitot-static system.

1. A pitot tube diagnostic system, comprising:
a data acquisition unit to acquire an electrical output signal of from a pitot-static system (PSS), the data acquisition unit being in electrical communication with the PSS, the output signal having a static component and a dynamic component; and a processing unit to monitor fluctuations of the dynamic component and to compare the fluctuations against a predetermined baseline level to identify fluctuations that deviate from the predetermined baseline level by a predetermined value to indicate impairment of the PSS.
