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

• It costs less to maintain

• It produces less drag during flight

• It supports more weight on landing

• It produces more force during braking

Why are aircraft fuel tanks vented to the outside?

• To let volatile gases escape

• To allow excess fuel to drain out of the tank

• To prevent the fuel from freezing in cold weather

• To maintain atmospheric pressure inside the tank

What should a pilot do during an explosive decompression incident?

• Rapidly reduce altitude

• Rapidly increase altitude

• Rapidly reduce airspeed

• Rapidly increase airspeed

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

• To check the grade of fuel in the tank

• To reduce the pressure in the tank

• To ensure the tank is not overfilled

• To drain the tank of fuel vapors

• To clean contaminants from the tank

Which component of a circuit is responsible for doing work?

• Battery

• Load

• Switch

• Wire

Pilots should expect rime ice to form when flying through what types of clouds?

• Cirrus

• Cumulus

• Nimbus

• Stratus

What is the purpose of an alternator control unit?

• Breaks the circuit in the event of an overload or malfunction

• Provides voltage and current

• Protects electrical components from power spikes

• Creates electricity used by electrical components

What indicators does a pilot use to monitor the status of electrical systems on the aircraft? Select all that apply.

• Altimeter

• Ammeter

• Load meter

• Tachometer

• EGT gauge

An aircraft designed to fly upside down would most likely have which type of fuel system?

• Gravity feed fuel system, because the fuel would be stored above the wings even when the aircraft is upside down

• Gravity feed fuel system, because the fuel would be pumped into the engine even when the aircraft is upside down

• Inverted fuel system, because the fuel would be pressurized even when the aircraft is upside down

• Inverted fuel system, because the flop tube would draw from the lowest point in the fuel tank even when the aircraft is upside down

At the maximum differential pressure, any increase in altitude will also cause an increase in cabin altitude.

• True

• False
