Non-Normal Methodology
ABCDs to improve operational effectiveness and reduce risk
Immediate Action
CABIN ALTITUDE WARNING or Rapid Depressurization
2. Establish crew communications.
Immediate Action
WARNING HORN (INTERMITTENT) or
WARNING LIGHT-CABIN ALTITUDE or
TAKEOFF CONFIGURATION
Don the oxygen masks and set the regulators to 100%
Establish crew communications.
2. If the intermittent warning horn sounds or a TAKEOFF CONFIG light (as installed) illuminates on the ground when advancing the thrust levers to takeoff thrust:
Assure correct airplane takeoff configuration.
Immediate Action
APU FIRE
Immediate Action
Aborted Engine Start
Limitation
Max Operating Pressure Altitude
41,000 ft
Limitation
Circle to Land Approach Manuever
Limitation
Air Systems
With engine bleed air switches ON, do not operate the air conditioning packs in HIGH for takeoff, approach, or landing. (unless advised by QRH)
Limitation
Anti-Ice and Rain
Limitation
Electrical Power
Limitation
Engines and APU
Limitation
Reverse Thrust
Reverse thrust is for ground use only.
Limitation
APU Altitudes of Operation
Max Altitude for Operation 41,000 ft
Max Altitude for Electrics Only 41,000 ft
Max Altitude for Bleed Air Only 17,000 ft
Max Altitude for Bleed and Electric 10,000 ft
Limitation Flight Controls (Flaps/Alternate Flaps)
Limitation Flight Controls (Speed brakes)
Limitation Fuel System (Tank Temps)
- Min Fuel Tank Temperature -37C
Limitation Fuel System (Fuel Distribution)
Main tanks must be full if the center tank quantity is greater than 1000 lbs.
Note: 1000 lbs may be retained in the center tank provided the effects of balance has been considered.
Note:Center tank fuel pumps must be ON for takeoff with more than 1000 lbs of fuel in the center tank.
Note:Some MEL items can override this limitation.
Limitation Fuel System (Ground Operations)
For ground operation, center tank fuel pump switches must not be positioned ON unless the center tank fuel quantity exceeds 1000 lbs, except when defueling or transferring fuel.
Note: Fuel may be transferred from tank to tank or the aircraft may be defueled with passengers onboard, provided the fuel quantity in the tank from which fuel is being taken is maintained at not less than 2000 lbs. Deplane all passengers and non-essential crew members when defueling a tank or transferring fuel from a tank that has fuel below 2000 lbs until the process has been completed and respective fuel boost pumps are turned off.
Limitation Fuel System (Center Tank Pump Switches)
Corresponding center tank fuel pump switch must be positioned off when a center tank LOW PRESSURE light illuminates.
Note: When established in level flight attitude, both center tank pump switches should be positioned ON again if the center tank contains usable fuel.
Note:If the center tank is empty, both center tank fuel pump switches must be positioned OFF when the first center tank fuel pump LOW PRESSURE light illuminates.
-Center Tank fuel pumps must not be ON unless personnel are available on the flight deck to monitor the low pressure lights.
Limitation Fuel System (Circuit Breakers)
Flight deck crews must not reset tripped fuel quantity indicator, fuel pump, or fuel pump control circuit breakers.
Limitations
Cargo Bay Fire Suppression
Aircraft must land within 60 minutes (Non-ETOPS) or 180 minutes (ETOPS) of initial discharge of the fire suppression system.
Limitation
TCAS
Limitation
Circuit Breakers
The in-flight reset of a tripped circuit breaker should only be accomplished when directed by the QRH. Allow approximately 2 minutes for cooling before resetting.
Resetting a tripped circuit breaker other than when directed by the QRH must be done as follows:
A tripped circuit breaker may only be reset once. Allow approximately 2 minutes for cooling before resetting. An in-flight reset should only be accomplished if, in the judgement of the Captain, regaining use of that system is critical to the safe conduct of flight.
