A320 Landing Gear, Brakes, Lights

On this E/WD, how do you interpret the NW STRG DISC memo?

• The nose wheel steering has been disconnected by ground personnel.

• A failure in the nose wheel steering system has been detected.

• One of the pilots has pushed the PEDALS DISC pushbutton located on the steering handwheel.

• The nose wheel steering computer has finished it’s self test. Nose wheel steering is now available.

During push back, engine no. 2 is started. On memo page this action induces the NW TRG DISC indication. ECAM changing to amber: For which reason

• The NW STRG disconnect mechanism has failed.

• The yellow hydraulic system has build up pressure which might damage the NW STRG system when set to towing position.

• The nose wheel steering has been reconnected by ground personnel.

  The amber indication will disappear as soon as you start taxi

• The nose wheel steering is still disconnected. The memo has become amber because one engine is running.

After starting to taxi you perform the brake check. While pressing on top of the rudder pedals you feel the airplane decelerating but the BRAKES pressure indication remains 0. Which statement is true ?

• The BRAKES pressure indicator has failed.

• The indication is normal because the “BRAKES” press indicator is active on brake system alternate mode (yellow supply).

• You must perform the check again and press harder on the brakes until you get an indication.

• The indication is normal because with manual braking you are not able to apply enough pressure to be displayed on the BRAKES indicator.

Aircraft has to land on a wet runway . According to these indications; the AUTO/BRAKE is active.

• True

• False

On the ECAM SD WHEEL page, the 2 triangles appearing below each landing gear mean:

• Each triangle represents one tire.

• There are two computers providing information on the gear position. Each triangle represents the position detected by its associated computer.

• Each triangle represents one braking system (normal/alternate) available for the associated gear.

• The front triangle indicates that AUTO/BRK is available and the one in the back means that ANTI/SKID is available for that gear.

You have just set the L/G selector to the DOWN position. According to these indications...

• The L/G is locked.

  The L/G doors are open.

• The computers providing gear position information have failed.

• The L/G is up and not locked in the selected position. The L/G doors are open

• The L/G control system has failed. The gear will not extend.

How do you interpret the following indications?

• The nose gear is in transit.

• All gears are down and locked.

• One L/G control system is inoperative.

  The nose landing gear is not downlocked.

• The nose gear is down and locked.

  The nose gear doors are open.

How do you interpret a green arc appearing over one wheel indication?

• It marks the hottest brake with a temperature of more than 100 º Celsius.

• It indicates an abnormal high temperature.

• The ANTI/SKID system is automatically

  releasing the pressure of that brake.

• The L/G control system has detected a

  low tire profile.

The pilot flying asks you to perform ECAM actions.

What are your actions according to the first line of the ECAM procedure ?

• I must put the L/G selector to the UP position.

• The system is trying to recycle the gear automatically. I must wait until the first line disappears.

• I must put the L/G selector to the UP position and immediately to the DOWN position again.

• I must put the L/G selector to the UP position, wait until the gear has retracted, and then to the DOWN position again.

After a disagreement on landing gear position, you

have recycled the L/G but there are still indications as shown.

How do you perform the next ECAM action?

• According to the procedure L/G GRAVITY EXTENSION which is found in the Quick Reference Hand book (QRH).

• Recycle the L/G a second time. This time

  the gear will free fall automatically

• Pull the GRAVITY GEAR EXTN handcrank

  and turn it clockwise 3 turns.

• Pull the GRAVITY GEAR EXTN handcrank

  and turn it counterclockwise 3 turns.
