Take the Quiz Again 1 / 1 pts Question 1 Aircraft icing is NOT possible in summer because it is too warm to make supercooled water air traffic control directs aircraft to fly at altitudes where icing is not a problem precipitation falls as rain in summer instead of snow the standard atmosphere temperature profile does not apply aircraft icing IS possible in summer Downloaded by hana kunihiro (hana.k.3452g@gmail.com) lOMoARcPSD|36610382 E

Supercooled water doesn’t affect aircraft, because the heat from an aircraft evaporates the water Ice can increase frictional drag on the aircraft The drops of water freeze instantly (or almost instantly) to form ice on the aircraft The water can freeze on portions of the aircraft (e.g., the tail) that make it difficult to control (to drive or steer) the aircraft.
