Under-wing mount, L-shaped (requires separate mounting bracket) The Dynon Avionics AOA/Pitot probe performs two functions: airspeed sensing and angle of attack sensing. These functions require having two pressure ports on the tip of the probe. The normal pitot pressure port is on the front face of the probe and is designed to be insensitive to angle of attack. The second pressure port is located on an angled surface just under the pitot port and is designed to be very sensitive to AOA. The pressure from each port is delivered via separate air lines to the instrument where they are compared to previously calibrated scenarios specific to that aircraft. Heated AOA Pitot: The heated pitot includes a nichrome heating element that is regulated by a separate pitot heater controller unit supplied with the pitot. The controller actively monitors a temperature sensor embedded within the pitot head and regulates the power to maintain a constant temperature. This not only conserves energy but additionally prolongs the life of the heater. The controller also outputs a signal that can be wired to a warning light in the cockpit to warn the pilot anytime there is a malfunction or that the pitot is turned off. More information regarding the Heated Pitot can be found here.
