Question: Why is 'frost' on an aircraft wing considered dangerous, even in small amounts?
Answer options:
- It adds significant weight to the aircraft.
- It can block rudder movement. ✅ It disrupts smooth airflow over the wing, reducing lift and increasing drag.
- It interferes with radio communication.
Correct answer: It disrupts smooth airflow over the wing, reducing lift and increasing drag.
Explanation: Even a thin layer of frost significantly roughens the wing surface. This disrupts the smooth laminar flow of air, causing a reduction in lift and an increase in drag, making takeoff and climb performance severely degraded or impossible.
