Record 2 2008-04-22

English

Subject field(s)
  • Flight Controls (Aeroindustry)
  • Landing Gear (Aeroindustry)
CONT

The MLG [main landing gear] retracts inwards into the fuselage wheel well. Each MLG has two doors. The outboard door is rigidly attached at the strut. The inboard door operates by mechanical linkage to the strut and is held in up position by two uplock cylinders. This uplock is released when landing gear lever is placed in down position by hydraulic pressure, or by nitrogen pressure in emergency. The MLG is held, while airborne, in retracted position by hydraulic pressure in the actuator and by the inboard door mechanical uplock, if pressure drops. As the gear is extended, an internal lock in the actuator automatically locks it in fully extended positions.

CONT

La séquence d'extension/rétraction des trains est conditionnée par la position du levier de commande «rentrée/sortie» des trains et par la réponse des détecteurs de positions du train et des trappes. Elle commande successivement l'ouverture des trappes, le déverrouillage du train, l'extension du train, le verrouillage du train en position basse, puis la fermeture des trappes principales (et inversement lors de la rétraction).

Record 3 2008-04-22

English

Subject field(s)
  • Aircraft Airframe
CONT

The main entrance door is the primary means of aircraft access for passengers and crew. It consists of a door structure and an attached folding stairway with hand rails. The door and stairway must be unlocked and pushed out to initiate a controlled free-fall to the extended position. During closing, the stairway is unlocked and the door is retracted upward and inward by hydraulic pressure from the Auxiliary(AUX) hydraulic system. The door and stair operation accommodates any combination of landing gear strut and tire inflation. Its use requires no ground support equipment.

Record 4 2008-04-22

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The electrical system has four engine-driven generators, each powerful enough to supply the aircraft with sufficient electricity. Each of the two main landing gear pods carries an auxiliary power unit(APU) and air turbine motor(ATM) to supply electric/pneumatic and hydraulic power, respectively, for engine starts, ground air conditioning and heating, main landing gear kneeling operations, and forward/aft cargo door operations.
