Which components receive Half probe heating when a generator is on?

• A. AOA and Static Port
• B. Pitot Tubes
• C. Altimeters
• D. Cargo Doors

Answer: (B)

Probe heating is used to keep sensors from icing, which would distort readings. When electrical power from a generator is available, the system uses reduced or half power to heat the probes so you still get reliable data without overloading the electrical system. Pitot tubes are the ones that receive this half-power heat because losing accurate dynamic pressure data directly affects airspeed indications, which are critical for safe flight handling. Keeping the pitot tubes warm helps ensure you don’t get erroneous airspeed readings due to icing. The other components listed aren’t the targets of the half-probe heating in this configuration. AOA sensors and static ports have their own heating arrangements and aren’t the half-power heating focus here. Cargo doors don’t involve probe heating, and altimeters rely on the static system rather than the dynamic pressure measured by pitot tubes.
