False.

True.

Correct! Wrong!

Parking brake requires:

GREEN hydraulic pressure.

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

BLUE hydraulic pressure.

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!

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

The accumulators are part of the normal braking system.

Each system is powered by a different hydraulic system.

Each system is equipped with its own set of accumulators.

Correct! Wrong!

Which hydraulic system powers the landing gear normal operation?

YELLOW.

GREEN.

BLUE.

Correct! Wrong!

If GREEN hydraulic pressure is not available:

Automatic braking is inoperative and antiskid is operative.

Both automatic braking and antiskid are operative.

Automatic braking is operative and antiskid is inoperative.

Correct! Wrong!

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

False.

True.

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!

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

Alternate Braking is available but Antiskid is unavailable.

Alternate Braking and Antiskid are still available.

Normal and Alternate Braking are lost.

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.

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

Four.

Five.

Seven.

Correct! Wrong!

Alternate Braking mode with Antiskid is available:

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

In case of GREEN hydraulic low pressure.

When pushing on the rudder pedals.

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!

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

12 hours.

Between 15 and 24 hours.

8 hours.

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 does not extend because no hydraulic power is available.

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

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.

Input orders to the Nose Wheel Steering are available from:

Dave Nunez

The steering handwheels, the rudder pedals, and the Autopilot system.

The steering handwheels only.

The captain's side only.

Correct! Wrong!

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

At any speed on ground.

Below 73 kt.

Below 100 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.

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.

Manually reset the landing gear downlocks.

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

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 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!

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

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.

BLUE 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:

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!

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!

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

Yes.

No.

It depends which LGCIU is concerned.

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.

Correct! Wrong!
