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!

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

Normal braking is inoperative.

Brake temperature is greater than 300 deg.C.

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

Correct! Wrong!

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

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

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.

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

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

RUDDER PEDAL DISC pb is being pushed.

BSCU is inoperative.

Correct! Wrong!

The Brake and Steering Control Unit (BSCU) enables:

Normal and Alternate Braking.

Normal and Alternate Braking + Antiskid + Autobrake + Brakes Temperature

Normal and Alternate Braking + Antiskid + Autobrake.

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

Manually reset the landing gear downlocks.

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

Reset the system to the normal extension and retraction mode.

Correct! Wrong!

If GREEN hydraulic pressure is not available:

Automatic braking is operative and antiskid is inoperative.

Automatic braking is inoperative and antiskid is operative.

Both automatic braking and antiskid are operative.

Correct! Wrong!

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

Normal and Alternate Braking are lost.

Alternate Braking and Antiskid are still available.

Alternate Braking is available but Antiskid is unavailable.

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!
