Question: 1 / 400

In icing conditions during initial climb-out, what can be expected concerning ice accumulation?

Ice to accumulate on the underside of the wings due to the higher AOA.

In icing conditions during the initial climb-out, it is accurate to anticipate that ice will accumulate on the underside of the wings due to the higher angle of attack (AOA). As the aircraft climbs and the angle of attack increases to gain altitude, the airflow around the wings becomes more conducive to ice accumulation. This is because the airflow slows down over the top surface of the wing while increasing under the wing, resulting in lower pressure and potential for ice formation, particularly when supercooled water droplets are present in the environment.

Ice forming on the underside can lead to significant performance issues, including increased drag and reduced lift, which is critical during climb phases. Understanding where ice tends to accumulate helps pilots take appropriate measures, such as activating anti-icing systems before significant accumulation occurs, or considering alternate flight paths with warmer temperatures.

Recognizing the behavior of ice accumulation focuses on the aerodynamics of the wings and the specific conditions of flight, showing a clear relationship between climb dynamics and icing hazards.
