A system for power management of air data probes is provided. The system comprises a power source in an aircraft, and two or more air data probes electrically connected to the power source. Each of the air data probes comprises a body structure coupled to a fuselage of the aircraft, and at least one electrical heater coupled to the body structure and in electrical communication with the power source. A switching mechanism is coupled between the power source and the electrical heater of each of the air data probes. The switching mechanism is controllable such that the electrical heater of each of the air data probes is electrically connectable to the power source in parallel or in series.

An air data probe includes a probe body. The air data probe also includes a housing surrounding the probe body, wherein a cavity is defined between the probe body and the housing. The air data probe also includes a heater element disposed within the cavity between the probe body and the housing. The air data probe also includes a low melting point metal disposed within the cavity between the probe body and the housing, wherein engaging the heater element causes at least a portion of the low melting point metal to transition from a solid state to a liquid state.
