Loading Procedure for 60.4-Inch x 61.5-Inch Unit Load Devices (ULD) in the Lower Deck Aft Cargo-Compartment
WARNING:
MAKE SURE THAT YOU DO NOT CAUSE ACCIDENTAL MOVEMENT OF A ULD DURING THE LOADING PROCEDURE:
- USE SUFFICIENT LOADING PERSONNEL TO DO THE PROCEDURE SAFELY.
WARNING:
DO NOT TOUCH THE POWER DRIVE UNIT:
- UNTIL IT IS SUFFICIENTLY COOL TO PREVENT BURNS WHEN YOU DO THE MAINTENANCE TASK(S)
- DURING OPERATION TO PREVENT INJURY FROM PARTS THAT TURN.
CAUTION:
IF THE COMPARTMENT IS NOT FULL AFTER THE CARGO LOADING PROCEDURE, LIFT THE LATCHES AT ALL THE EMPTY ULD POSITIONS. THIS WILL PREVENT ACCIDENTAL MOVEMENT OF A ULD, IF ULD LATCHES BECOME DEFECTIVE DURING FLIGHT. ACCIDENTAL MOVEMENT OF A ULD CAN CAUSE DAMAGE TO EQUIPMENT.
NOTE: When the joystick of the control panel is released, it moves to the neutral position and the PDUs stop.
