Q

What type of system is designed to prevent the formation of ice?

A

Anti-ice

18
Q

What type of system is designed to remove ice once it has formed?

A

Deice

19
Q

What parts of an aircraft typically have ice protection systems?

A

Pitot and static ports
Fuel tank vents
Propeller blades
Wing and tail leading edges
Windshields

20
Q

What may also be installed on some aircraft to determine the extent of structural icing during night flights?

A

Wing inspection lights

21
Q

How do wing leading edge deicing boots work?

A

They inflate to break off the ice

22
Q

How do heated leading edges combat ice formation?

A

By preventing ice from forming

23
Q

How do the weeping-wing systems combat ice formation?

A

They discharge a chemical that melt ice

24
Q

One type of windshield anti-ice system directs a flow of ____________ to the windscreen. If used early enough, it prevents ice from building up on the windscreen.

A

Alcohol

25
Q

Which ice protection system commonly causes large errors in the aircraft standby compass?

A

Windshield heat

26
Q

True or false, propellers are immune to icing because their high-speed rotation prevents ice from forming.

A

False

27
Q

How are pitot and static ports, fuel vents, and stall-warning sensors typically heated to prevent ice formation?

A

Electrically
