Seven.

Correct! Wrong!

Parking brake requires:

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

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!

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

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

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.

Correct! Wrong!

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

False.

True.

Correct! Wrong!

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

True.

False.

Correct! Wrong!

Anti-skid is available:

With GREEN hydraulic pressure only.

With GREEN or BLUE hydraulic pressure.

With BLUE hydraulic pressure only.

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!

The Brake and Steering Control Unit (BSCU) enables:

Normal and Alternate Braking.

Normal and Alternate Braking + Antiskid + Autobrake.

Normal and Alternate Braking + Antiskid + Autobrake + Brakes Temperature

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!

Information on main landing gear panel are provided by:

BSCU (Braking and Steering Control Unit).

LGCIU 1 (Landing Gear Control Interface Unit).

LGCIU 2 (Landing Gear Control Interface Unit).

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.

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 by gravity, Nose Wheel Steering and braking are unaffected.

Landing gear extension is done using the BLUE hydraulic system, Nose Wheel Steering is lost.

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.

Autobrake system is disarmed by:

Depressing the rudder pedal disconnect pb.

Depressing both pedals.

Depressing at least one pedal.

Correct! Wrong!

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

Each system is equipped with its own set of accumulators.

The accumulators are part of the normal braking system.

Each system is powered by a different hydraulic system.

Correct! Wrong!
