Answer sheet (1)

1. Why are rain protection systems important for aircraft?

To ensure a clear view for pilots, especially during takeoff, landing, and taxiing in rainy conditions, ensuring safe operations.

2. What ensures that a wiper failure on one side does not affect the other?

A separate electric motor powers each wiper.

3. When should rain repellent be used, and why should it not be used with wipers?

Rain repellent should only be used on a wet windshield. It should not be used with wipers because it can reduce visibility further.

4. What is the purpose of hydrophobic seal coating, and how is it maintained?

The coating causes water to bead and roll off the windshield, improving visibility. It wears off over time and needs to be reapplied periodically.

5. How does the pneumatic rain removal system work, and what is its source of hot air?

Hot air directed over the windshield breaks raindrops into smaller particles and blows them away. The hot air is sourced from the engine bleed air system or an electric blower.

00:24

What are the two main functions of an ice protection system on an aircraft?

1. a. Increase engine thrust and reduce lift
2. b. Prevent ice formation and remove already-formed ice
3. c. Improve pilot visibility and reduce air pressure
4. d. Heat cockpit windows and maintain cabin temperature

01:22

Why is it important to protect the leading edge of an aircraft's wings from ice formation?

1. a. It improves the aircraft’s visibility.
2. b. It increases engine efficiency.
3. c. It ensures the proper lift is maintained.
4. d. It helps in navigation during bad weather.

1. a. Thermal anti-icing
2. b. Electric anti-icing
3. c. De-icing boots
4. d. Transparent heating elements

03:22

How does thermal anti-icing prevent ice formation on the wings and engine inlets?

1. a. By inflating rubber boots to break the ice
2. b. By using resistance elements powered by electricity
3. c. By directing hot air from the engine to the affected areas
4. d. By installing transparent heating elements on the surface

04:40

What is used to prevent ice formation on cockpit windows, and what is its main requirement?
