Question

After cycling of the deicing boots, residual ice will A. decrease as the airspeed decreases or the temperature increases. B. remain constant until leaving the icing conditions. C. increase as the airspeed or temperature decreases.

Answer 1

C. increase as the airspeed or temperature decreases.

Step-by-step explanation:

You want to know the effect of temperature and airspeed on residual ice after the deicing boots on an aircraft wing have been cycled.

Icing

Ice can accumulate on airplane wings when temperature, humidity, and/or precipitation conditions are just right. An airplane can defend itself against this potentially dangerous condition by ...

• heating the wing to melt the ice or prevent its formation
• flexing the deicing boot to break off any accumulated ice.

After the deicing boot has been cycled, there may be residual ice. This residual ice may increase if the conditions conducive to ice formation remain. That is, it will ...

increase as the airspeed or temperature decreases, choice C.

Additional comment

Of course, the best approach to icing is to avoid flying in conditions conducive to ice formation, or to pass through those conditions as quickly as possible.
