According to the Clean Air Concept, may an aircraft take off with frost, ice, or snow on critical surfaces?

• A. Yes
• B. No
• C. Only if the ice is light
• D. Only with approval from the captain

Answer: (B)

The correct answer is that an aircraft may not take off with frost, ice, or snow on critical surfaces according to the Clean Air Concept. This principle emphasizes safety in aviation operations, particularly regarding the performance and control of the aircraft during takeoff. Frost, ice, or snow can significantly affect the aerodynamic properties of the aircraft. These contaminants can disrupt the airflow over the wings and control surfaces, leading to a reduction in lift and an increased risk of stalls during critical phases of flight. This is especially important during takeoff, where precise control is vital for a safe ascent. Maintaining aircraft surfaces clear of frost, ice, and snow ensures that optimal aerodynamic performance is achieved. Therefore, strict adherence to de-icing and anti-icing procedures is crucial to ensure the safety of the flight. Any presence of these contaminants on critical surfaces is a serious safety concern, making it mandatory that the aircraft be completely free of such conditions before takeoff.
