An electronic multi-function probe (MFP) is provided for positioning adjacent an aircraft skin. The electronic MFP includes a plurality of pressure sensing ports and an electronics housing. Positioned within the electronics housing are air data processing circuitry and stall protection system processing circuitry. The air data processing circuitry is configured to generate air data parameters, including airspeed and altitude, as a function of pressures at the plurality of pressure sensing ports. The stall protection system processing circuitry of the electronic MFP is configured to detect stall conditions as a function of angle of attack and at least one air data parameter from the air data processing circuitry, and to generate stall protection system outputs indicative of the detected stall conditions.

A total air temperature sensor includes a probe secured to a first side of a vehicle surface. The probe includes an air inlet and a temperature sensing element. Air flows into the air inlet and passes by the temperature sensing element. The temperature sensing element produces a temperature sensing element electrical signal as a function of a temperature of the air. The total air temperature sensor also includes an electronics package secured to a second side of the vehicle surface. Electronics in the electronics package receive the temperature sensing element electrical signal from the temperature sensing element and determine a total air temperature as a function of the temperature sensing element electrical signal.
