Prevent wheel skid to improve braking efficiency.

Correct! Wrong!

Autobrake system is disarmed by:

Depressing the rudder pedal disconnect pb.

Depressing both pedals.

Depressing at least one pedal.

Correct! Wrong!

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

It depends which LGCIU is concerned.

No.

Correct! Wrong!

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

90 degrees.

72 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.

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.

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

Brake temperature is greater than 300 deg.C.

Normal braking is inoperative.

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

Correct! Wrong!

The Brake and Steering Control Unit (BSCU) enables:

Normal and Alternate Braking + Antiskid + Autobrake + Brakes Temperature

Normal and Alternate Braking + Antiskid + Autobrake.

Normal and Alternate Braking.

Correct! Wrong!

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

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.

Landing gear extends but landing gear doors stay open.

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.

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.

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

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

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.

1000 ft RA.

800 ft RA.

750 ft RA.

Correct! Wrong!

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

False.

True.

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.

False.

True.

Correct! Wrong!

Parking brake requires:

GREEN hydraulic pressure.

BLUE hydraulic pressure.

GREEN hydraulic pressure for normal use and the BLUE hydraulic pressure for alternate use.

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!

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

Four.

Five.

Seven.

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 parking brake accumulator maintains the parking pressure for at least:

12 hours.

Between 15 and 24 hours.

8 hours.

Correct! Wrong!

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

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

BSCU is inoperative.

RUDDER PEDAL DISC pb is being pushed.

Correct! Wrong!

When depressing the pedal disconnect pb on a steering handwheel:

Rudder pedal orders to nose wheel are deactivated.

Hydraulic isolation valve to Nose Wheel Steering is closed.

Rudder and steering handwheel inputs to nose wheel are deactivated.

Correct! Wrong!

The red arrow on the landing gear indicator panel illuminates:

During transit.

If the landing gear is not locked in selected position.

If the landing gear is not downlocked in landing configuration.

Correct! Wrong!

Initial pedal force or displacement produces more braking action in alternate mode than in normal mode.

True.

False.

Correct! Wrong!

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

Steering is not energized but A/SKID is working when the aircraft is moving on ground.

Aircraft uses alternate brakes and A/SKID is available.

Both N/W STRG and A/SKID are de-energized.

Correct! Wrong!

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.

Anti-skid is available:

With GREEN hydraulic pressure only.

With BLUE hydraulic pressure only.

With GREEN or BLUE hydraulic pressure.

Correct! Wrong!

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

False.

True.

Correct! Wrong!

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

At ground spoiler extension provided speed is below 72 kt.

At 110 kt.

At ground spoiler extension.

Correct! Wrong!

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

Alternate Braking and Antiskid are still available.

Alternate Braking is available but Antiskid is unavailable.

Normal and Alternate Braking are lost.

Correct! Wrong!

Which hydraulic system powers the landing gear normal operation?

YELLOW.

GREEN.

BLUE.

Correct! Wrong!

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

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

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.

Correct! Wrong!

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

Manually reset the landing gear downlocks.

Reset the system to the normal extension and retraction mode.

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

Correct! Wrong!
