Cargo Bay Fire Protection
Aircraft must land within 60 min of discharge of fire protection (800 ETOPS: 195 min)
-
Speed Brakes
- - Lower altitude limit: 1000' agl
- - In flight do not extend beyond flight detent
- - Do not use in flight unless flaps are fully retracted
-
Flaps
- - Max altitude 20,000'
- - Alternate flap duty cycle in flight is one complete cycle, then 5 min off. A complete cycle is movement from position 0 to 15 and back to 0. The alternate flap switch must be in the OFF position for 15 sec before reversing the direction of flap movement
-
Min/Max Fuel Tank Temperature
- Min: -37C
- Max: 49C
- Note Jet A freezes at -40C. Other fuels freeze at lower temperatures
-
Center Tank > 1000lbs rules
- Main tanks must be full and center fuel tank pumps must be on.
- Use center tank to depletion before using wing tanks
- Notes: - 1000 lbs may be retained in center tank if weight & balance have been considered.
- -Center tank fuel pumps must beON for all operations with more than 1000 pounds of fuel in thecenter tank.
- - Some MEL can override this limitation
-
Center Fuel Tank During Ground Operation
Fuel pump switches must be off unless center tank quantity > 1000 lbs (except when defueling or transferring fuel)
-
Fuel Transfer and Defueling on the Ground
Pax and non-essential crew members may only stay on board if tank from which fuel is taken is maintained > 2000lbs
-
NG: Center Tank Fuel Pump Low Pres
- Corresponding center fuel pump switch must be positioned to OFF when a Low Pres light illuminates
- Notes: - In level flight pumps should be positioned back to ON if the center tank still contains usable fuel
- - if the tank is empty both pumps must be switched OFF when the first pump Low Pres light illuminates
- - Intentional dry running is prohibited
-
Center Tank Fuel Pump Operation - General
Only if personnel in flightdeck to monitor low pressure lights
-
NG: Holding in Icing Condition
Allowed but only with flaps retracted. Holding in icing with Flaps extended is prohibited
-

Engine Warm-Up and Cool-Down
- At least 2 min warm-up after rollback before t/o thrust.
- At least 1 min near idle before shutdown
-
Reverse Thrust

-
What circuit breakers are not to be reset:
fuelquantity indicator, fuel pump or fuel pumpcontrol circuit breakers.
-
Use of WX Radar:
Do not operate near people, fuel spills or during fueling
-
IRS Shutdown procedure:
Do not remove AC power for at least 30 sec after IRS shutdown
-
Operating PACKS in High:
If on Engine Bleed Air the Packs cannot be in HIGH for takeoff, approach or landing (unless the QRH directs to do so (i.e. smoke removal)
