Which areas should direct spraying of deicing/anti-icing fluids be avoided?

• A. Fuselage
• B. Wings and tail
• C. Brakes/wheels
• D. Windshield

Answer: (C)

Direct spraying of deicing or anti-icing fluids should be avoided on brakes and wheels due to the potential for reduced braking effectiveness and safety concerns. These fluids can create a slippery residue that may impair the functionality of the braking system, leading to dangerous situations during takeoff or landing. It is crucial to ensure that all components essential for safe ground operations, such as brakes, are free from any substances that could affect their performance. In contrast, while it might be necessary to apply fluids to the wings and tail to prevent ice accumulation, these surfaces are designed to handle the added fluid and benefits from their protective properties. Furthermore, the fuselage and windshield are generally treated differently, focusing primarily on visibility and aerodynamics rather than the specific safety issues directly related to braking performance.
