    You had to unlock and move the interior door to get to the LEER and Left PDB, when you move the door back to its stowed position, don't forget to lock it again. (If you don't it will come crashing aft during takeoff.)

  3. Emergency Power . . . CHECKED

    Press the Emergency Power ARM switch and verify both of the ON capsules are lit and . . .

    . . . as well as the copilot's clock.

  5. Standby Instruments / MCDU #1 (Fuel Quantity) / MCDU #3 . . . CHECKED
  6. images

    The EBDI and SFD should be powered. MCDU #1 should display fuel quantity (the engine data will be dashed when the engines are not operating)

    images

    MCDU #3 will display backup radio information

  7. LEFT / RIGHT BATTERIES . . . ON (22 - 27V DC)

    images
  8. EMERGENCY POWER-OFF . . . SELECT

    images
  9. CABIN PRESSURE CONTROL . . . CHECK OUTFLOW VALVE OPEN
  10. images

    Unless the main cabin door has been opened more than once since MANUAL mode was selected, this should just require deselecting MANUAL mode, since with WOW the auto mode will drive it open.

  11. Gear Handle / Lights . . . DOWN / 3 GREEN

    images
  12. Parking Brake Accumulator Pressure . . . CHECK
  13. images

    You will need to cycle the parking brake a few times to get to the accumulator pressure, which should read 1200 psi at 70°F, varying 25 psi for each 10°F multiple.

  14. FLAPS . . . SET (10° RECOMMENDED FOR PREFLIGHT)
  15. images

    Yes, this works just fine in the GV/G550, but it doesn't in the G450. The Operating Manual once called for using the EMER STAB and now calls for using ALT FLAP. Both procedures often result in a FLAPS FAIL state. You should leave the flaps where they are until you have AC power on the aircraft.

  16. PARK / EMERGENCY BRAKE . . . SET
  17. images
  18. BRAKE PRESS Indicator . . . CHECK (3000 PSI)
  19. images
  20. Fuel Quantity . . . CHECK
