1. Over a recent 10-year period, wing contamination by snow, frost, or ice was responsible for more than 30 aircraft accidents.
2. According to the FARs, how much snow, frost, or ice may be present on a light GA aircraft prior to takeoff?
A layer not exceeding 2 mm in thickness
An amount not exceeding 15 percent of the total wing surface area
None (the aircraft must be free of all snow, frost, and ice)
The FARs do not specify
3. According to wind tunnel testing, ____ percent of a wing's total lift may be lost due to very small particles (1 to 2 mm in diameter) adhering to its surface.
2 to 8
9 to 13
22 to 33
42 to 53
4. Who is responsible for ensuring that snow, frost, or ice is removed from an aircraft?
Fixed base operator (FBO)
Pilot in command
5. What is the best action a pilot can take to minimize wing contamination by snow, frost, or ice?
Hangar the aircraft
Place a tarp over the aircraft
Install deicing equipment
Apply an approved anti-icing product in advance of the freezing precipitation
6. The NTSB recommends which of the following preflight actions with regard to wing contamination?
Hangar the aircraft before each flight
Feel the wings for snow, frost, and ice accumulation
Cancel the flight if more than 1/4 inch of ice or frost is present on the airframe
7. Using a deicing solution during preflight to remove all snow, frost, and ice accumulation from the wings and fuselage ensures that your aircraft is safe for flight.
8. Which of the following products can be applied to the wings and fuselage as a deicer?
All of the above
9. Due to its liquid state, rain should not concern pilots flying below a cloud layer.
10. During cold-weather operations, visually inspecting the aircraft's wings should be part of a pilot's before-takeoff checklist.
