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.

When the A/SKID N/W STRG switch is set to OFF:

Correct! Wrong!

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

In case of landing gear gravity extension, the nose wheel steering is lost.

True.

False.

Correct! Wrong!

A green arc overhead wheel temperature on ECAM WHEEL page indicates:

This wheel is the hottest and Brake Temp is more than 100 deg.C.

Normal braking is inoperative.

Brake temperature is greater than 300 deg.C.

Correct! Wrong!

When depressing the pedal disconnect pb on a steering handwheel:

Rudder pedal orders to nose wheel are deactivated.

Rudder and steering handwheel inputs to nose wheel are deactivated.

Hydraulic isolation valve to Nose Wheel Steering is closed.

Correct! Wrong!

If one UNLK indication remains on at gear extension, the landing gear position can be confirmed using the WHEEL SD page (information from LGCIU 1 and 2): only one green triangle on each landing gear is sufficient to confirm that the landing gear is downlocked.

True.

False.

Correct! Wrong!

There are two braking systems available, the normal and the alternate system:

The accumulators are part of the normal braking system.

Each system is equipped with its own set of accumulators.

Each system is powered by a different hydraulic system.

Correct! Wrong!

Information on main landing gear panel are provided by:

LGCIU 2 (Landing Gear Control Interface Unit).

BSCU (Braking and Steering Control Unit).

LGCIU 1 (Landing Gear Control Interface Unit).

Correct! Wrong!

If GREEN hydraulic pressure is not available:

Both automatic braking and antiskid are operative.

Automatic braking is inoperative and antiskid is operative.

Automatic braking is operative and antiskid is inoperative.

Correct! Wrong!

The purpose of the RESET position on the LDG GEAR GRVTY EXTN panel is to:

Actuate the BLUE ELEC pump to provide an alternate source of hydraulic pressure to the landing gear system.

Manually reset the landing gear downlocks.

Reset the system to the normal extension and retraction mode.

Correct! Wrong!

Which hydraulic system powers the landing gear normal operation?

YELLOW.

BLUE.

GREEN.

Correct! Wrong!

If both pilots turn their steering handwheels at the same time:

Priority is given to the first pilot to turn its handwheel.

Inputs are algebraically added.

Inputs are algebraically added only if both handwheels are turned in the same direction.

Correct! Wrong!

The red arrow on the landing gear indicator panel illuminates:

If the landing gear is not locked in selected position.

During transit.

If the landing gear is not downlocked in landing configuration.

Correct! Wrong!

In the event of an aborted takeoff with autobrake armed, automatic braking is initiated:

At 110 kt.

At ground spoiler extension.

At ground spoiler extension provided speed is below 72 kt.

Correct! Wrong!

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 normal braking are lost.

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

Correct! Wrong!

If Brake and Steering Control Unit (BSCU) channels 1 and 2 are inoperative:

Alternate Braking is available but Antiskid is unavailable.

Normal and Alternate Braking are lost.

Alternate Braking and Antiskid are still available.

Correct! Wrong!

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

It depends which LGCIU is concerned.

Yes.

No.

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.

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

True.

False.

Correct! Wrong!

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

RUDDER PEDAL DISC pb is being pushed.

BSCU is inoperative.

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

Correct! Wrong!

True.

False.

Correct! Wrong!

Anti-skid is available:
