ABSTRACT:
An air data system includes a probe body defining a probe passageway which has a probe inlet and a probe outlet. The probe passageway is heated and couples an air pressure from the probe inlet to the probe outlet. A sensor has a sensor inlet for receiving the air pressure. The sensor provides a sensor output indicative of the air pressure. A coupling body has a coupling passageway which couples the air pressure from the probe outlet to the sensor inlet. The coupling passageway has a cooled surface for condensing moisture from air in the coupling passageway. The coupling body has a reservoir positioned relative to the cooled surface to collect the condensed moisture. The reservoir is heated to evaporate the condensed moisture.
