Flaps in icing conditions should not be sustained unless which phase?

In icing conditions, ice buildup on the wing surfaces changes lift and stall characteristics, and extending flaps increases the surface area where ice can cling. That makes the wing more susceptible to a loss of control and higher stall speeds if flaps are kept out for long. The safe practice is to avoid sustaining flap extension unless you’re in the approach or landing phase, where you need the extra lift at very low speeds to achieve a controlled descent and landing. Once you’re past the approach, flaps are retracted to reduce ice accumulation and restore normal flight characteristics. So the best approach is to only use extended flaps during approach/landing and keep them retracted at other times in icing conditions.
