800 ft RA.

750 ft RA.

1000 ft RA.

Correct! Wrong!

False.

True.

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.

Parking brake requires:

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

BLUE hydraulic pressure.

GREEN hydraulic pressure.

Correct! Wrong!

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

BSCU is inoperative.

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

RUDDER PEDAL DISC pb is being pushed.

Correct! Wrong!

Information on main landing gear panel are provided by:

LGCIU 2 (Landing Gear Control Interface Unit).

LGCIU 1 (Landing Gear Control Interface Unit).

BSCU (Braking and Steering Control Unit).

Correct! Wrong!

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

Below 100 kt.

At any speed on ground.

Below 73 kt.

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.

Alternate Braking mode with Antiskid is available:

If A/SKID and N/W STRG switch is set to OFF position.

When pushing on the rudder pedals.

In case of GREEN hydraulic low pressure.

Correct! Wrong!

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

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

Inputs are algebraically added.

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

Correct! Wrong!

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

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.

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

Correct! Wrong!

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

Aircraft uses alternate brakes and A/SKID is available.

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

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

Correct! Wrong!

The Brake and Steering Control Unit (BSCU) enables:

Normal and Alternate Braking + Antiskid + Autobrake.

Normal and Alternate Braking + Antiskid + Autobrake + Brakes Temperature

Normal and Alternate Braking.

Correct! Wrong!

When depressing the pedal disconnect pb on a steering handwheel:

Hydraulic isolation valve to Nose Wheel Steering is closed.

Rudder pedal orders to nose wheel are deactivated.

Rudder and steering handwheel inputs to nose wheel are deactivated.

Correct! Wrong!

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

82 degrees.

72 degrees.

90 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.

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

12 hours.

Between 15 and 24 hours.

8 hours.

Correct! Wrong!

Anti-skid is available:

With GREEN or BLUE hydraulic pressure.

With BLUE hydraulic pressure only.

With GREEN hydraulic pressure only.

Correct! Wrong!

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!

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!

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

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.

Manually reset the landing gear downlocks.

Correct! Wrong!

The purpose of the Antiskid is to:

Establish and maintain a selected deceleration during landing.

Reduce the braking delay in the event of a rejected takeoff.

Prevent wheel skid to improve braking efficiency.

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!

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

Normal and Alternate Braking are lost.

Alternate Braking is available but Antiskid is unavailable.

Alternate Braking and Antiskid are still available.

Correct! Wrong!

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

True.

False.

Correct! Wrong!

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

Yes.

No.

It depends which LGCIU is concerned.

Correct! Wrong!
