What is the main effect of ice accumulation on an aircraft during flight?
Increases thrust and lift.
Decreases weight and drag.
Increases weight and drag, and decreases thrust and lift.
Has no significant impact on performance.
What is the fundamental distinction between anti-icing systems and de-icing systems?
Anti-icing systems remove already formed ice, while de-icing systems prevent its formation.
Anti-icing systems prevent the formation of ice, while de-icing systems are designed to remove ice once it has formed.
Both systems have the same function, but they are used in different parts of the aircraft.
Anti-icing systems use heat, while de-icing systems use chemicals.
What components of the aircraft can be equipped with anti-ice systems to prevent ice formation?
Only the surfaces of the wings and tail.
Heated Pitot tubes, static ports, fuel vents, stall detectors, and windshields.
Only the propellers and windshields.
Only the antennas and engine air intakes.
How does the alcohol anti-ice system for propellers work to prevent ice accumulation?
The alcohol is electrically heated to melt the ice.
The alcohol is discharged from a nozzle and the centrifugal force distributes it along the leading edge of the blade.
The propeller blades vibrate to shed the ice.
The alcohol is mixed with the fuel to lower the freezing point.
If an anti-ice boot on the blade does not heat one of the blades, what consequence could this have?
Increased efficiency of the propeller.
Severe vibration of the propeller due to an uneven load on the blades.
Decreased fuel consumption.
Improvement in the directional stability of the aircraft.
What side effect can the electric current used in the electric resistance heating method for windshields cause?
Increased visibility in foggy conditions.
Compass deviation errors of up to 40 degrees.
Reduction of noise in the cabin.
Improvement in radio communication.
How do pneumatic de-icing boots work to remove ice accumulation on the leading edges of wings and tail?
They release a chemical liquid that melts the ice.
They inflate with air from a pneumatic pump to break the ice.
They use high-frequency vibrations to detach the ice.
They generate heat to evaporate the ice.
The presence of anti-ice and de-ice systems on an aircraft, does it necessarily mean that it is approved to fly in icing conditions?
Yes, as long as the systems are operational.
No, the approval to fly in icing conditions depends on the specific certification of the aircraft.
Only if the aircraft is multi-engine.
Yes, but only for short-duration flights.
