What is the effect of frost on the aircraft wing?

• A. Improves lift
• B. Enhances throttle response
• C. Negatively affects airflow
• D. Increases engine efficiency

Answer: (C)

Frost on an aircraft wing negatively affects airflow, which is crucial for maintaining lift during flight. When frost accumulates on the wing's surface, it disrupts the smooth flow of air over the wing. This disrupted airflow can lead to increased drag and a decrease in the wing's aerodynamic efficiency. In ideal conditions, the air can flow smoothly over a clean wing, allowing for effective lift generation. However, the presence of frost introduces roughness and irregularities that create turbulence in the airflow. This turbulence can cause a decrease in lift and an increase in stall speed, meaning the aircraft requires a higher speed to maintain adequate lift. As a result, frost significantly compromises the aerodynamic performance of the aircraft, making it critical for pilots and maintenance crews to ensure the wings are clear of any frost or ice before takeoff.
