What conditions typically trigger anti-ice operations during flight?

Anti-ice operations are driven by the presence or expectation of icing on the aircraft surfaces. Pilots rely on weather information, ice indicators, and visual icing to decide when to arm and use anti-ice systems, following standard operating procedures. The goal is to prevent ice from accumulating enough to affect aerodynamics, engine performance, or controllability. Icing can occur at various stages of flight and at various altitudes, so the decision isn’t limited to a single phase; it may be required near takeoff/landing because those phases often involve low speeds and proximity to clouds or precipitation, but the trigger is the icing conditions themselves, not the phase of flight.
