Flight Operations Manual Practice Test

What part of the aircraft must deicing fluid be applied?

Whole aircraft Wings only Engines only Fuselage only

Correct Answer:

Whole aircraft

Explanation:

In icing conditions, deicing fluid is applied to all surfaces of the aircraft that could accumulate ice. Ice on any exposed part can disrupt aerodynamics, engine performance, and flight instruments, so treating the entire airplane is essential. Wings are critical for lift, but ice on the fuselage, tail, control surfaces, and engine inlets can all degrade handling, stall behavior, and thrust. The fluid lowers the ice’s adhesion and provides a window of protection (holdover time) for taxi, takeoff, and initial climb. If any area is missed, ice can continue to form or shed onto other surfaces, compromising safety. Thus, the whole aircraft must be treated.
