What is the function of ice detection probes?

The function of ice detection probes is to detect the formation of ice on the aircraft's wings, control surfaces, or engine inlets. These probes are critical for flight safety as ice accumulation can significantly affect the aerodynamic properties of the aircraft and lead to potential control difficulties. By providing real-time data on ice formation, these probes enable the flight crew to take necessary precautions, such as activating de-icing systems. Recognizing ice formation early allows pilots to maintain aircraft performance, ensure safe operation, and reduce the risk of hazardous conditions during flight.

The other options relate to different functions that do not align with the purpose of ice detection probes. For example, cabin temperature regulation pertains to environmental control systems, whereas increasing engine power is associated with thrust management. Circulating air in the cockpit falls under cabin ventilation systems. Thus, the primary role of ice detection probes is accurately represented by the ability to identify ice formation, which enhances overall flight safety.
