Limitations Flashcards
To Learn Limitations for Southwest Airlines 737 (36 cards)
What is the fuel limitation for Cruise (AD 2002-19-52)
NG - If more than 2000lbs in center tank, both center tank switches much be re-positioned to ON.
NG- Turn one center fuel pump switch to OFF during climb or cruise when center tank fuel quantity reaches approximately 2000 pounds. Open crossfeed to minimize imbalance. When MASTER CAUTION and FUEL lights illuminate, turn the remaining center tank fuel pump switch to off without delay and close CROSSFEED valve.
Center tank fuel pump switches must be selected to OFF when both center fuel pump low pressure lights illuminate.
Max operating altitude 700/800
41000
What is the MAX altitude for operating the APU in the 300/500
35,000ft
What is the MAX altitude for operating the APU BLEED AIR and ELECTRIC in the 300/500?
10,000ft
What is the limitation on the IRS?
Do not remove AC Power from the aircraft for at least 30 seconds after IRS shutdown.
What is the MIN fuel tank Temperature?
-37 C
What are the Limitations on thrust reversers?
Reverse thrust is for ground use only.
What is the limitation for ice and rain?
NG- Holding in icing conditions with flaps extended is prohibited.
What is the MAX altitude for operating the AP ELECTRIC ONLY in the 300/500?
35,000ft
What is the MAX altitude for operating the APU in the NG?
41,000ft
Is there any limitations on Ground Start?
(CL) Minimum duct start pressure is 30psi, reducing .5psi per 1000 ft above sea level.
What is the radar limitation?
Do not operate the wx radar during fueling, near fuel spills or near people.
What are the circuit breaker limitations?
A tripped CB 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.
Flight crews must not reset tripped fuel quantity, fuel pumps or fuel pump control CB’s.
What is the fuel limitation for descent (AD 2002-19-52)
NG- Turn on one center fuel pump switch OFF at beginning of descent if <3000lbs of fuel remain in center tank. Open CROSSFEED valve to minimize fuel imbalance. When MASTER CAUTION and FUEL system annunciation lights illuminate, turn the remaining center tank fuel pump OFF without delay and close X-feed.
If an extended period of level flight is required prior to approach & landing (holding) and fuel remains in center tank, a single center tank pump switch may be ON if both pumps were previously OFF. X-feed should be opened to prevent a fuel imbalance.
What is the limitation on normal flaps?
Do not extend flaps above 20,000ft pressure altitude
What are the TCAS Limitations
Flight crews must immediately respond to TCAS information (both TA’s & RA’s) by using the TCAS guidelines located in the QRH Section P Non-Normal Maneuvers/Profiles.
Pilots are authorized to deviate from an ATC clearance to the extent necessary to comply with the RA
After starting, what are the engine limitations for stabilization.
On the first flight of the day, operate engines at or near idle, after rollback, for a minimum of FIVE minutes prior to applying takeoff thrust.
Operate engines at or near idle, after rollback, for a MINIMUM of TWO minutes prior to applying Takeoff thrust.
What is the fuel limitation for takeoff?
(CL) Center tank fuel pumps must be ON for takeoff with more than 1000lbs of fuel in the center tank.
NG- Both center tank fuel pump switches must be positioned OFF for Takeoff if the center tank fuel quantity is <5000lbs.
What is the MAX altitude for operating the AP ELECTRIC ONLY in the NG?
41000ft
What are the engine limitations after landing?
When operational conditions permit, engines should be idle for THREE minutes before shutdown.
Operate engines at idle for a MINIMUM of ONE minute prior to shutdown.
What are the speedbrake limitations?
- Do not use speedbrakes in flight below 1000ft AGL
- In flight, do not extend the speedbrake lever beyond the flight detent.
- In flight, do not extend the speedbrakes unless the flaps are fully retracted.
What is the limitation on the alternate flaps?
Alternate flap duty cycle in flight is one complete cycle, then 5 minutes off. A complete cycle is movement from position from 0 to 15 and back to 0. The alternate flap switch must be in the OFF position for 15 seconds before reversing the direction of flap movement.
What are the fuel distribution limitations?
Use center tank fuel to depletion followed by wing tank fuel.
1000lbs may be retained in the center tank provided the effects of balance have been considered.
What is the MAX altitude for operating the APU BLEED AIR & ELECTRIC in the NG?
10,000ft
