A2.U8.SB.L2 Anti-Icing Systems

Pilots should expect rime ice to form when flying through what types of clouds? (A2.U8.SB.L2)

• Cirrus
• Cumulus
• Nimbus
• Stratus

Key aircraft parts/components that should be protected from ice formation include _________. Select all that apply. (A2.U8.SB.L2)

• Wing leading edge
• Landing gear
• Wing struts
• Windshield
• Propeller

What effects can occur as a result of airplane icing? Select all that apply. (A2.U8.SB.L2)

• The stall speed may increase.
• Aircraft weight may increase.
• Visibility may increase.
• Drag may increase.
• Lift may increase.

Which of the following two conditions must exist in order for aircraft icing to form? Select two. (A2.U8.SB.L2)

• Aircraft surface temperature is 32 degrees fahrenheit or less
• Ambient air temperature is above freezing
• Visible moisture is present
• It must be raining

How does a weeping wing system prevent icing on wings? (A2.U8.SB.L2)

• Vents redirect hot air from the engines to the leading edges of wings to melt ice.
• Electrical heating elements within the wings increase the temperature of the surface.
• Antifreeze is pumped out through small holes along the leading edges of wings.
• A pneumatic pump inflates rubber bladders to break up ice on the leading edges of wings.

A(n)____________ system inhibits the formation of ice onto the aircraft when a(n) _______________ removes ices that has already formed on the aircraft.

• Deicing : Anti-icing
• Anti-icing : Deicing

Why is it recommended that pilots avoid using flaps, gears, and spoilers during icing conditions? (A2.U8.SB.L2)

• More fuel is required using these devices during icing environments.
• They increase surface area and ice accumulation.
• Drag devices are likely to get stuck.
• Maneuvers would be minimized during icing environments.

True or False. (A2.U8.SB.L2) Aircraft icing in flight is most likely to occur when it is snowing.

• True
• False
