Aircraft Icing

For light GA aircraft, structural icing is one of the greatest hazards of winter flying, accounting for more than 150 accidents during a recent 10-year period. Ice can accumulate quickly, decreasing lift and increasing drag to the point where continued flight is impossible. Learn how to avoid icing conditions (and what to do if you fly into the unexpected) with this ASF Safety Quiz.

1. Most icing accidents are caused by ice that has not been removed from the aircraft before flight.

2. Most icing accidents occur during which phase of flight?

3. A layer of ice that is as thin and textured as a piece of coarse sandpaper can reduce lift by ____ percent.

4. In addition to fronts, ____-pressure areas are likely to contain icing conditions.

5. Which part of a typical GA aircraft is most likely to accumulate ice first?

6. How can a pilot recognize an imminent tail stall caused by ice accumulation?

7. Carburetor heat is an example of ____ equipment.

8. The most obvious early symptom of airframe icing will be a decrease in ___.

9. If you have inadvertently accumulated ice, you should lower flaps to help stabilize the approach and landing.

10. If the pitot tube becomes completely iced up in flight (including its drain hole), indicated airspeed will ____.
