Which of the following is a method for managing ice and other contaminants on the airframe during flight?

• A. De-icing fluid
• B. Heated hangar
• C. Both A and B
• D. None of the above

Answer: (A)

Managing ice and other contaminants on the airframe during flight relies on active anti-ice/de-ice measures that affect the surface while air is flowing. De-icing fluid is a practical method used to remove ice from the airframe and to delay further accretion, which is why it’s the correct choice here. A heated hangar, by contrast, is a ground-based facility used for storage or maintenance, not a method you apply or rely on during flight. Therefore it isn’t a technique for managing ice while the aircraft is in the air. The option that implies both would incorrectly include the ground-based hangar concept, and none would be incorrect because de-icing fluid is indeed a valid method.
