The two-wheel nose gear comprises an oleopneumatic shock strut and a nosewheel steering system. It retracts rearward into the fuselage.

False.

True.

Correct! Wrong!

It retracts forward into the fuselage.

The ECAM memo N/W STRG DISC is displayed. What does it mean?

BSCU is inoperative.

RUDDER PEDAL DISC pb is being pushed.

Nose Wheel Steering selector on nose gear is on "Towing" position.

Correct! Wrong!

YELLOW.

BLUE.

GREEN.

In case of GREEN hydraulic low pressure.

Correct! Wrong!

During landing, Nose Wheel Steering (NWS) is available:

Below 100 kt.

Below 73 kt.

At any speed on ground.

Correct! Wrong!

Nosewheel steering control authority depends on aircraft speed. Rudder pedals provide nosewheel steering control when the speed is below 100 kt at landing, or up to 150 kt for takeoff.

In case of GREEN hydraulic system loss, what is the correct statement?

Landing gear extension is done using the BLUE hydraulic system, Nose Wheel Steering is lost.

Landing gear extension is done by gravity, Nose Wheel Steering and braking are unaffected.

Landing gear extension is done by gravity, Nose Wheel Steering and normal braking are lost.

Correct! Wrong!

The flight crew may arm the autobrake system provided all following conditions are:

GREEN pressure available, Antiskid electrically powered and no failure in the braking system.

BLUE pressure available, Antiskid electrically powered and no failure in the braking system.

GREEN pressure available, Antiskid deactivated and no failure in the braking system.

Correct! Wrong!

The IAS is 300 kt - Landing gear selector is set to DOWN:

Landing gear extends but landing gear doors stay open.

Landing gear extends but it is over VLE, a check has to be performed after landing.

Landing gear does not extend because no hydraulic power is available.

Correct! Wrong!

All gears and doors are hydraulically-actuated by the green hydraulic system. Hydraulic supply is automatically isolated by closing a safety valve above 280 kt. It is maintained closed until the landing gear lever is moved to the DOWN position and the aircraft speed decreases below 280 kt.

ALTERNATE BRAKING WITHOUT ANTISKID - Accumulators are designed to supply at least _____ full brake applications.

Five.

Seven.

Four.

Correct! Wrong!

Anti-skid is available:

With GREEN or BLUE hydraulic pressure.

With GREEN hydraulic pressure only.

With BLUE hydraulic pressure only.

Correct! Wrong!

The parking brake accumulator maintains the parking pressure for at least:

12 hours.

8 hours.

Between 15 and 24 hours.

Correct! Wrong!

The Brake and Steering Control Unit (BSCU) enables:

Normal and Alternate Braking + Antiskid + Autobrake.

Normal and Alternate Braking.

Normal and Alternate Braking + Antiskid + Autobrake + Brakes Temperature

Correct! Wrong!

The steering handwheels control the nosewheel steering angle up to plus or minus _____ in either direction.

72 degrees.

90 degrees.

82 degrees.

Correct! Wrong!

A visual red warning on the overhead panel indicates to the crew that an oversteer (plus or minus 93 degrees) has occurred.

In case of one LGCIU failure, is the landing gear system affected?

No.

It depends which LGCIU is concerned.

Yes.

Correct! Wrong!

After a free fall extension, it is possible to restore normal operation, provided green hydraulic pressure is available.

False.

True.

Correct! Wrong!

GEARS AND DOORS - CONTROLS AND INDICATORS - The red arrow, and associated ECAM warnings come on red in approach at _____, if the landing gear is not downlocked in landing configuration.

750 ft RA.

800 ft RA.

1000 ft RA.

Correct! Wrong!

Alternate Braking and Antiskid are still available.

Normal and Alternate Braking are lost.

Alternate Braking is available but Antiskid is unavailable.
