Unit 8 Review

What is one advantage of retractable landing gear over fixed landing gear?

• It costs less to maintain

• It supports more weight on landing

• It produces more force during braking

• It produces less drag during flight

When hydraulic fluid pressure exceeds a set pressure, the selector valve opens to reduce pressure and routes fluid back to the reservoir.

• True

• False

Why are aircraft fuel tanks vented to the outside?

• To maintain atmospheric pressure inside the tank

• To prevent fuel from freezing in cold weather.

• To allow excess fuel to drain out of the tank.

• To let volatile gases escape.

How does a weeping wing system prevent icing on wings?

• 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.

What should a pilot do during an explosive decompression incident?

• Rapidly increase airspeed

• Rapidly reduce airspeed

• Rapidly reduce altitude

• Rapidly increase altitude

Which of the following two conditions must exist in order for aircraft icing to form? Select two.

• Aircraft surface temperature is 32 degrees Fahrenheit or less

• Visible moisture is present

• Ambient air temperature is above freezing

• It must be raining.

 

Why does a pilot drain a small amount of fuel from each sump before each flight? Select all that apply.

• To reduce the pressure in the tank

• To check the grade of fuel in the tank

• To drain the tank of fuel vapors

• To clean contaminants from the tank

What steps should a pilot take if they believe there is an electrical fire on board? Select all that apply.

• Extinguish fire, if possible

• Declare an emergency

• Turn off the master switches

• Land as soon as possible

Which component of a circuit is responsible for doing work?

• Battery

• Switch

• Wire

• Load

What effects can occur as a result of airplane icing? Select all that apply.

• Lift may increase

• The stall speed may increase

• Aircraft weight may increase

• Drag may increase
