What is the primary danger of clear ice?

• A. It is easily removed from wings
• B. It blocks visibility for the pilot
• C. It dehydrates the wings
• D. It slows down aircraft speed

Answer: (B)

The primary danger of clear ice is that it blocks visibility for the pilot. When ice accumulates on the wings and control surfaces of an aircraft, it disrupts airflow and can significantly alter the aerodynamic characteristics of the aircraft. This can lead to performance issues, such as decreased lift and increased drag. Moreover, ice formation can obscure instruments and reduce the clarity of the pilot’s view, making it challenging to gauge the aircraft's status and surroundings, which is critical for safe operation during flight. While ice can also affect speed and performance, blocking visibility presents an immediate and pressing safety concern during different phases of flight, such as takeoff and landing, where accurate visual references are vital. Therefore, ensuring clear visibility is essential for piloting safely in all conditions, especially in situations where ice may accumulate.
