C-40 LANDING GEAR/NOSEWHEEL STEERING

  1. Image Upload 1
    When does #1 illuminate?
    Illuminated (red) –

    -landing gear is not down and locked (with either or both forward thrust levers retarded to idle, and below 800 feet AGL).

    -related landing gear is in disagreement with LANDING GEAR lever position (in transit or unsafe).
  2. How can you tell if the landing gear is down and locked if one of the lights is burned out?
    Landing gear is down and locked as long as one green landing gear indicator light (center panel or overhead panel) for each gear is illuminated.
  3. What is the OFF position for?
    Removes hydraulic pressure from the landing gear system
  4. What is the override trigger for?
    Allows the landing gear lever to be raised, bypassing the lever lock
  5. What normally releases the lever lock on the landing gear?
    Air/ground sensing
  6. What happens when the landing gear lever is moved to the UP position?
    Hydraulic pressure releases the uplocks, brakes automatically stop tire rotation, gear retracts, mechanical uplocks lock the gear in the up position.  Nosewheel rotation is stopped by snubbers and held up by an overcenter lock.
  7. If the aircraft loses system A hydraulic pressure, can the landing gear be retracted?
    Yes, by the landing gear transfer unit (LGTU)
  8. Under what conditions does the landing gear transfer unit (LGTU) operate?
    Hydraulic system B supplies the volume of hydraulic fluid required to raise the landing gear at the normal rate when all of the following conditions exist:

    -airborne

    -No. 1 engine RPM drops below a limit value

    -LANDING GEAR lever is positioned UP

    -either main landing gear is not up and locked.
  9. Following a manual gear extension, can the landing gear be retracted normally if System A pressure is restored?
    Yes.  Landing gear retraction is disabled if the manual gear extension door is open.  Accomplish the following steps:

    -close the manual extension access door.  

    -move the LANDING GEAR lever to DOWN with hydraulic system A pressure available, and then

    -position the LANDING GEAR lever to UP.
  10. What happens when the landing gear lever is moved to the DOWN position?
    Hydraulic pressure releases the uplocks, landing gear extends via hydraulic pressure, airloads and gravity, overcenter mechanical and hydraulic locks hold the gear at full extension
  11. Which system normally powers the landing gear?
    System A
  12. Which hydraulic system normally powers nose wheel steering?
    System A
  13. Which hydraulic system normally powers alternate nose wheel steering?
    System B

    When does #1 function?
    Push – silences landing gear configuration warning aural indication at flaps up through 10 and above 200 feet RA.

    Note: The aural indication cannot be silenced with the cutout switch at flaps greater than 10
