Limitations Flashcards
Circle-to-Land Approach Maneuver
- WX mins - 1,000 ft ceiling and 3 mi vis
- MDA of 1,000 ft above AFE unless restricted to higher mins on the approach chart
Maximum Operating Pressure Altitude
41,000 ft
Air Systems
With engine bleed air switches ON, do not operate the air conditioning packs in HIGH for takeoff, approach, or landing
NOTE: Fire protection non-normal procedures (QRH) take precedence over the statement regarding no air conditioning pack in HIGH during takeoff, approach, or landing
Anti-Ice and Rain
- Holding in icing conditions with flaps extended is prohibited
- Do not operate the wing anti-ice on the ground when the OAT is above 10 C (50 F)
- Do not use wing anti-ice as a substitute for ground deicing/anti-icing and inspection procedures which are necessary to comply with operating rules
- Do not operate weather radar during fueling, near fuel spills, or near people
Electrical Power
- (NG) On the ground, limit one generator operation (engine driven) to maximum of 215 amps
- (MAX) Limit one generator operation (engine driven) to a maximum of 215 amps on the ground or in the air
- Do not remove AC power from the aircraft for at least 30 seconds after IRS shutdown
Circuit Breakers
- 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
- A tripped circuit breaker may only be reset once. An in-flight reset should only be accomplished (other than directed by QRH) if, in the judgement of the captain, regaining use of that system is critical to the safe conduct of the flight
- Flight deck crews must not reset tripped fuel quantity indicator, fuel pump or fuel pump control circuit breakers
Maximum EGT for Ground Start
725 C (NG)
753 C (MAX)
Engine Operating Times
- Operate engines at or near idle, after rollback, for a minimum of 2 minutes (NG), 3 (MAX), prior to applying takeoff thrust
- Operate engines at or near idle for a minimum of 1 minute (NG), 3 minutes (MAX) prior to shutdown
Reverse Thrust
Intentional use of reverse thrust in flight is prohibited
APU Max Altitude for Operation
41,000 ft
APU Max Altitude for Electric Only
41,000 ft
APU Max Altitude for Bleed Air Only
17,000 ft
APU Max Altitude for Bleed and Electric
10,000 ft
Max Flap Extension Pressure Altitude
20,000 ft
Alternate Flap Duty Cycle
Alternate flap duty cycle in flight is one complete cycle, then 5 minutes off. A complete cycle is movement from position 0 to 15 and back to 0. The ALTERNATE FLAP position switch must be in the OFF position for 15 seconds before reversing the direction of flap movement
Speedbrakes
- In flight, do not extend the speed brake lever beyond the FLIGHT DETENT
- Do not use speed brakes in flight below 1000 ft AGL
- In flight, do not use speedbrakes with greater than flaps 10
- 700W - Do not operate the aircraft at speeds in excess of 320 kt at weights over 143,000 lb if the speedbrake wing load alleviation system is inoperative
Max Fuel Tank Temperature
49 C
Min Fuel Tank Temperature
-37 C
Fuel Distribution
- Main tanks must be full if the center tank quantity is greater than 1000 pounds
- 1000 lbs may be retained in the center tank provided the effects of balance have been considered
- Center tank fuel pumps must be ON for all operations with more than 1000 lbs of fuel in the center tank
- Some MEL items can override this limitation
Fuel Transfer/Defuel
- For ground operation, center tank fuel pump switches must not be positioned to ON unless the center tank fuel quantity exceeds 1000 lbs, except when defueling or transferring fuel
- 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 the fuel is being taken is maintained at not less 2000 lb. Deplane all passengers until the process has been completed and the respective fuel boost pumps are turned off if the tank has a fuel quantity below 2000 lbs
Center Tank Fuel Pump Switches
- Corresponding center tank fuel pump switch must be positioned to OFF when a center tank LOW PRESSURE light illuminates
- (7) When on the ground, if the center tank fuel pump LOW PRESSURE light illuminates with useable fuel greater than 1000 lb in the center tank, refer to 16.12.5 Center Tank Fuel Pump LOW PRESSURE Light Illuminated on the Ground
- When established in level flight attitude, both center tank pump switches should be positioned ON again if the center tank contains usable fuel
- 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
Cargo Bay Fire Suppression
- Aircraft must land within 60 minutes (8E and MAX8E 180 minutes) of initial discharge of the fire suppression system
TCAS
- Pilots are authorized to deviate from an ATC clearance to the extent necessary to comply with the TCAS II RA
- Flight crews must respond immediately to TCAS information (both TAs and RAs) by using TCAS guidelines located in the QRH Maneuvers Chapter
