    Reset the system to the normal extension and retraction mode.

    Lift the red handle and turn clockwise a 3 turns.
  21. If the Landing Gear was gravity extended using the hand crank on the center pedestal, what other systems will be inoperative?
    Nose wheel steering only.
  22. Auto brake may be armed with the parking brake on.
  23. Can normal landing gear operation be restored after a gravity extension if green hydraulic pressure is available?
    It may be possible if the gravity extension was not caused by a failure of the landing gear mechanism.
  24. To control the nose steering, the BSCU (brake and steering control unit) receives inputs from:
    • Steering handwheels.
    • Rudder pedals.
    • The autopilot.
  25. When the landing gear is gravity extended, will nose wheel steering be available?
  26. Auto brakes, if selected, will only be activated by:
    The ground spoiler extension command.
  27. A shortening mechanism attached to the _____ reduces main landing gear length by retracting the shock absorber into the main leg during retraction.
  28. When the LDG GEAR GRVTY EXTN selector switch is in the DOWN position, the two motorized actuators are electrically powered to close the hydraulic cut off valve and to disengage door and gear uplocks which permit the nose and main gear to deploy by gravity and automatically lock down.
  29. There are two triangles for each gear on the ECAM WHEEL page. What do they represent?
    Each triangle represents the position detected by one of the two computers systems.
  30. Nose wheel steering is available:
    Below 100 kts.
  31. When depressing the pedal disconnect pushbutton on a steering handwheel:
    Rudder pedal order to nose wheel steering are disconnected.
  32. Nose wheel steering is provided by two actuators powered by the green hydraulic system and electrically signaled by the brake and steering control unit (BSCU).
  33. What system pressure does the ACCU PRESS and BRAKES pressure indicator indicate?
    Yellow brake accumulator and yellow brake system pressure to the left and right brakes.
  34. The normal brake system uses _____ hydraulic pressure and the alternate brake system uses _____ hydraulic pressure backed up by the hydraulic brake accumulator.

    Both N/W STRG and A/SKID are de-energized.
  36. The BSCU (brake and steering control unit) has two independent channels. Both can be active at the same time.
  37. ECAM: if you see a green arc shown over a wheel indication
    It marks the hottest brake with a temperature of more than 100�C.
  38. Nose wheels and main wheels have fusible plugs that prevent the tires from bursting if they overheat.
    • False.
    • Only the main wheels!
  39. With the A/SKID & N/W STRG switch in the ON position, if the BSCU detects a brake system malfunction and/or normal braking is not available:
    Transition to the alternate brake system is automatic.

    No. When the PARK BRK is set, the other braking modes are deactivated.
