windshield wipers and anti icing fluid.

• - A blanket-type heating system, an electric heating element in the windshield, and a

ribbon-type Heating system.

• - An electric heating element in the windshield, a heated air circulating system, and a hot

water system.

Answer:

An electric heating element in the windshield, a heated air circulating system, and windshield wipers and anti icing fluid.

A brush or a squeegee.Question 6: Why should a chemical rain repellant not be used on a dry windshield?

• - It will etch the glass.
• - It will restrict visibility.
• - It will cause glass crazing.

Answer:

It will restrict visibility.Question 7: What mixture may be used as a deicing fluid to remove frost from an aircraft surface?

• - Ethylene glycol and isopropyl alcohol.
• - Methyl ethyl ketone and ethylene glycol.
• - Naphtha and isopropyl alcohol.

Answer:

Ethylene glycol and isopropyl alcohol.Question 8: What is the principal characteristic of a windshield pneumatic rain removal system?

• - An air blast spreads a liquid rain repellant evenly over the windshield that prevents raindrops

from clinging to the glass surface.

• - An air blast forms a barrier that prevents raindrops from striking the windshield surface.
• - A pneumatic rain removal system is simply a mechanical windshield wiper system that is

powered by pneumatic system pressure.

Answer:

An air blast forms a barrier that prevents raindrops from striking the windshield surface.Question 9: What should be used to melt the ice in a turbine engine if the compressor is immobile because of ice?

• - Deicing fluid.
• - Anti-icing fluid.
• - Hot air.

Answer:

Hot air.

Question 10: Why are the tubes in deicer boots alternately inflated?

• - Alternate inflation of deicer boot tubes keeps disturbance of the airflow to a minimum.
• - Alternate inflation of deicer boot tubes does not disturb airflow.
• - Alternate inflation of deicer boot tubes relieves the load on the air pump.

Answer:

Alternate inflation of deicer boot tubes keeps disturbance of the airflow to a minimum.
