Which factor may influence the decision to activate anti-ice procedures?

Activating anti-ice procedures is critical for ensuring aircraft safety, particularly in icy conditions. The decision to implement these procedures is notably influenced by temperature changes. When the temperature drops near or below freezing, moisture in the air can freeze on critical surfaces of the aircraft, such as wings and control surfaces, leading to a significant decrease in performance and control.

Understanding how temperature can create conditions for ice accumulation is vital for pilots. For instance, if temperatures are hovering around the freezing point and the aircraft is flying through visible moisture, the risk of ice formation increases substantially, warranting the activation of anti-ice systems.

While factors like cockpit distraction, flight duration, and wind speed can impact a flight, they do not directly affect the formation of ice in the way that temperature does. Therefore, recognizing temperature as the prime factor helps pilots make swift and informed decisions in order to maintain safety when flying in conditions that might lead to ice buildup.
