If you see frost on the wings, what is the recommended course of action?

• A. No go or De-Ice if approved for FIKI
• B. Proceed with takeoff as normal
• C. Perform a pre-flight inspection and continue
• D. Takeoff if conditions are clear and favorable

Answer: (A)

Seeing frost on the wings indicates that there is a layer of ice that can significantly impact the aircraft's performance by altering the shape of the wings and thereby reducing lift. This frost creates an uneven surface and can severely affect the aerodynamics of the aircraft. The recommended course of action when encountering frost is to either not proceed with the flight or to de-ice the aircraft if it is certified for flight into known icing (FIKI). De-icing ensures that the wings are clear of any frost or ice that could compromise the safe operation of the aircraft. Prioritizing a thorough de-icing process helps ensure that lift and performance are within safe operating limits for takeoff, as even a small accumulation of frost can result in insufficient lift, leading to hazardous situations. Proceeding with takeoff, conducting only a pre-flight inspection, or taking off under the assumption that conditions are clear and favorable does not address the potential risks associated with frost on the wings, making these alternatives unsafe choices.
