Abstract: In accordance with at least one aspect of this disclosure, an air data probe (100) includes, an outer shell (102) defining an airflow path (104) from an inlet (106) at a proximal end (108) thereof to a distal end (110) thereof and a heater (118) configured to be installed within the outer shell an in the airflow path, the water dam (120) comprising, one or more sensing elements (114) at a distal end thereof. The system also includes, a water dam (120) disposed on or in the heater winding and between a proximal end (122) and distal end (124) of the heater winding configured to impede a flow of water droplets and ice crystals to permit proper drain hole operation, prevent moisture buildup in rear areas of the probe and pressure lines, and prevent interaction of the flow of water and the one or more sensing elements. The water dam is configured to mechanically stabilize itself on or in the heater winding during installation of the heater winding and water dam into the outer shell.
