or
circle-to-land minimums on approach chart
Maximum Operating Pressure Altitude
41,000 feet
Air System/Bleed air switches restriction
Do not operate in HIGH for takeoff, approach, or landing
*QRH takes precedence (Cargo Fire & Smoke and Fumes Removal)
Limitation for holding in icing conditions
Holding in icing conditions with flaps extended is prohibited
Wing Anti-ice Limitations (2)
- Do not operate wing anti-ice on the ground when OAT is 10*C or above
- Do not use wing anti-ice as a subsitute for ground deicing/anti-icing and inspection procedures which are necessary to comply with operating rules
Weather Radar Limitations (3)
Do not operate weather radar:
1. During fueling
2. Near fuel spills
3. Near people
Single Generator Limitation
NG: On the ground, one engine driven generator, 215 amps
MAX: Ground or air, one engine driven generator, 215 amps
How long should you wait before removing AC power after IRS shutdown
Minimum of 30 seconds
In flight reset of a tripped circuit breaker
- Only when directed by the QRH
- Allow 2 minutes for cooling before resetting
Resetting tripped circuit breakers other than when directed by the QRH
- May only be reset once
- 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.
Maximum EGT for ground start
NG: 725C
MAX: 735C (non-memory item)
Engine warm up
Operate engines at or near idle before takeoff for…
NG: 2 minutes
MAX: 3 Miinutes
*Both: 5 minutes on first flight of the day recommended
Engine cool down
Operate engines at or near idle before shutdown for…
NG: 1 minute (3 when conditions permit)
MAX: 3 minutes
Reverse Thrust
Intentional selection of reverse thrust in flight is prohibited
Max altitude for APU operation
41,000 feet
Max altitude for APU Electric only
41,000 feet
Max altitude for APU Bleed Air only
17,000 feet
Max altitude for APU Electric & Bleed Air
10,000 feet
Max altitude for flap extension
20,000 feet pressure altitude
Alternate Flap duty cycle in flight
- One complete cycle then 5 minutes off
*a complete cycle is 0-15-0 - The ALTERNATE FLAP position switch must be in the OFF position for 15 seconds before reversing the direction of flap movement
In flight use of Speedbrakes, all models
- do not use speedbrakes below 1000 feet AGL
- Do not extend the speedbrake lever beyond the FLIGHT DETENT
- Do not use speedbrakes with greater than flaps 10
-700W speedbrake restriction
With the wing load alleviation system inoperative, do not operate the aircraft at speeds over 320KTS with weights over 143,000 lbs
Max fuel tank temperature
+49*C
Min fuel tank temperature
-37*C
note: Jet A freeze point is -40C, and other listed fuels freeze at lower temperatures
Fuel Distribution
Main tanks must be full if center tank quantity is greater than 1000 lbs
*1000 lbs may be retained if CG effects have been considered
*center tank pumps must be on if more than 1000 lbs in the center tank
*some MEL items can override this limitation
Center tank - Ground Operations
Center tank pump switches must not be positioned on unless quantity is greater than 1000 lbs except when de fueling or transferring fuel
de-fueling/transferring fuel with pax aboard
Fuel quantity must not go below 2000 lbs in the tank fuel is being taken from or must deplane all passengers and non-essential crew
Center tank - fuel pump switches
- Must not be ON unless personnel on the flight deck to monitor
- Must be positioned OFF when corresponding LOW PRESSURE light illuminates
*when established in level flight, turn pumps back on if center tank contains usable fuel
*if the center tank is empty, both pumps must be turned off when the first LOW PRESSURE light illuminates
* (7) if LOW Pressure with more than 1000 lbs on the ground, refer to AOM Center Tank fuel pump LOW PRESSURE Light Illuminated On The Ground
Fuel related circuit breakers
Do Not Reset tripped breakers for
1. fuel quantity
2. fuel pump
3. fuel pump control
How long to land after initial cargo fire suppression system
Non-ETOPS - 60 minutes
ETOPS - 180 minutes
TCAS Limitations
- Pilots are authorized to deviate from ATC clearances to the extent necessary to comply with a TCAS RA
- Flight crews must immediately respond to TCAS information by using guidelines located in AOM 5.18, Non-Normal Maneuvers
