Abstract: A pitot tube diagnostic system and method for determining the health of a pitot tube is disclosed. The pitot tube diagnostic system is configured to be temporarily connectable to or permanently installable in an airplane's pitot-static system, which allows the pitot tube diagnostic system to be utilized during pre-flight inspections and/or in-flight conditions. The pitot tube diagnostic system is in electrical communication with the pitot-static system for acquisition of output signals and analysis thereof. Thus, the pitot-static diagnostic system is able to diagnose anomalies in the pitot-static systems that are representative of the overall health and efficiency of the pitot-static system.
