True.

False.

Correct! Wrong!

If GREEN hydraulic pressure is not available:

Both automatic braking and antiskid are operative.

Automatic braking is inoperative and antiskid is operative.

Correct! Wrong!

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

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.

Autobrake system is disarmed by:

Depressing at least one pedal.

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 Antiskid is to:

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

Establish and maintain a selected deceleration during landing.

Prevent wheel skid to improve braking efficiency.

Correct! Wrong!

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

False.

True.

Correct! Wrong!

Anti-skid is available:

With GREEN hydraulic pressure only.

With GREEN or BLUE hydraulic pressure.

With BLUE hydraulic pressure only.

Correct! Wrong!

When depressing the pedal disconnect pb on a steering handwheel:

Rudder and steering handwheel inputs to nose wheel are deactivated.

Hydraulic isolation valve to Nose Wheel Steering is closed.

Rudder pedal orders to nose wheel are deactivated.

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!

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 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.

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.

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!

Input orders to the Nose Wheel Steering are available from:

Dave Nunez

The steering handwheels only.

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

The captain's side only.

Correct! Wrong!

Alternate Braking mode with Antiskid is available:

When pushing on the rudder pedals.

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

In case of GREEN hydraulic low pressure.

Correct! Wrong!

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

Brake temperature is greater than 300 deg.C.

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

Normal braking is inoperative.

Correct! Wrong!

The two-wheel nose gear comprises an oleopneumatic shock strut and a nosewheel steering system. It retracts rearward into the fuselage.

True.

False.

Correct! Wrong!

It retracts forward into the fuselage.

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.

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

Inputs are algebraically added.

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 braking are unaffected.

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 normal braking are lost.

Correct! Wrong!

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

Seven.

Five.

Four.

Correct! Wrong!

The red arrow on the landing gear indicator panel illuminates:

During transit.

If the landing gear is not downlocked in landing configuration.

If the landing gear is not locked in selected position.

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!

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

90 degrees.

82 degrees.

72 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.

Which hydraulic system powers the landing gear normal operation?

GREEN.

BLUE.

YELLOW.

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 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!

Parking brake requires:

BLUE hydraulic pressure.

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

GREEN hydraulic pressure.

Correct! Wrong!

Information on main landing gear panel are provided by:

LGCIU 1 (Landing Gear Control Interface Unit).

LGCIU 2 (Landing Gear Control Interface Unit).

BSCU (Braking and Steering Control Unit).

Correct! Wrong!

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

True.

False.

Correct! Wrong!

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

Yes.

It depends which LGCIU is concerned.

No.

Correct! Wrong!

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