Answer 10

• Main (wing) tanks must be full if the center fuel tank quantity is greater than 1000 pounds.
• For ground operation, center tank fuel pump switches must NOT be positioned to ON unless the center tank fuel quantity exceeds 1000 pounds, except when defueling or transferring fuel.
• Center Tank Fuel Pumps must not be selected ON unless personnel are available on the flight deck to monitor the low pressure lights.
• Flight Crews must not reset tripped fuel quantity, fuel pump, or fuel pump control circuit breakers.

Question 11

(Checked Limitations) What are the Speedbrake Limitations?

Answer 11

• Do not use speedbrakes in flight below 1000 feet AGL.
• In flight, do not extend the Speedbrake Lever beyond the Flight Detent.
• In flight, do not use speedbrakes with Flaps greater than 10.

Question 12

(Checked Limitations) What is the minimum fuel tank Temperature?

Answer 12

-37 degrees C

Question 13

(Checked Limitations) What are the TCAS limitations?

Answer 13

• Flight Crews must immediately respond to TCAS information (both TA’s and RA’s) by using the TCAS (Traffic Avoidance) guidelines located in the QRH Maneuvers chapter
• Pilots are authorized to deviate from an ATC clearance to the extent necessary to comply with the TCAS II Resolution Advisory (RA)

Question 14

(Checked Limitations) What is the maximum altitude for operating the APU BLEED AIR ONLY?

Answer 14

17,000 feet

Question 15

(Checked Limitations) What is the Maximum Operating Pressure Altitude for the NG and MAX?

Answer 15

FL410

Question 16

(Checked Limitations) What are the limitations for tripped circuit breakers?

Answer 16

• A tripped circuit breaker may only be reset once. Allow approximately two minutes for cooling before resetting. An in-flight reset should only be accomplished if in the judgment 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 pump, or fuel pump control circuit breakers.
• The Flight Deck Crew should not cycle (pull and reset) a circuit breaker at any time unless the cycle meets one or more of the following criteria (• directed by the QRH, • directed by a procedure listed in the B737 AOM, FOM, MEL or Operations Binder, • coordinated and approved by MX)
• IN FLIGHT - The in-flight reset if a tripped circuit breaker should only be accomplished when directed by the QRH. Allow approximately 2 minutes for cooling before resetting.

Question 17

(Checked Limitations) Other than speed limitations, what is the limitation on the use of normal flaps?

Answer 17

Do not extend flaps above 20,000 feet

Question 18

(Checked Limitations) What is the limitation on operating the radar?

Answer 18

Do not operate the WX Radar during fueling, near fuel spills, or near people.

Question 19

(Checked Limitations) What are the Engine limitations for cool down after landing?

Answer 19

NG - Operate Engines at or near idle for a MINIMUM of ONE minute prior to shutdown (recommend THREE minutes prior to shutdown)

MAX - Operate Engines at or near idle for a MINIMUM of THREE minutes prior to shutdown.

Question 20

(Checked Limitations) What Is the limitation for operating on one generator on the ground?

Answer 20

NG - Limit one Generator Operation (Engine Driven) to a Maximum of 215 Amps.

Question 21

(Checked Limitations) You are ready for takeoff, you have 1500 pounds of fuel in the center tank, what position should your center fuel pump switches be in?

Answer 21

They should both be ON.

Question 22

(Checked Limitations) What is the limitation on the Alternate Flaps?

Answer 22

Alternate Flap duty cycle in flight is one complete cycle, then 5 minutes OFF (a complete duty cycle is movement from position 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.

Question 23

(Checked Limitations) What is the maximum altitude for operating the APU ELECTRIC ONLY?

Answer 23

FL410

Question 24

(Checked Limitations) What is the EGT limitation for Ground Start?

Answer 24

NG - 725 degrees C
MAX - Redline

(The EEC does not supply RED LINE protection, but will shut the engine down if it senses an impending hot start)

Question 25

(Checked Limitations) After starting, what are the limitations for Engine stabilization?

Answer 25

Operate Engines at or near IDLE, after rollback for a MINIMUM of TWO minutes (NG) or THREE minutes (MAX) prior to applying takeoff thrust.

(RECOMMENDATION: On the First Flight of the Day; operate engines at or near idle, after rollback, for minimum of FIVE minutes prior to applying takeoff thrust)

Question 26

(Checked Limitations) What are the Fuel Distribution limitations?

Answer 26

• Main (wing) tanks must be full if the Center Tank quantity is greater than 1000 pounds.
• Use Center Tank to depletion followed by wing tank fuel.
• 1000 pounds 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 pounds of fuel in the center tank (Some MEL items can override this limitation).

Question 27

(Checked Limitations) What is the limitation for a Circle to Land Approach Maneuver?

Answer 27

WX minimums are 1000 ft. ceiling and 3 miles visibility. BOTH ceiling and visibility criteria are required. If the Jeppesen approach chart specifies minimums higher than 1000/3, now those higher minimums are required to execute the circle to land approach maneuver.

(Use a Minimum Descent Altitude (MDA) of 1000 ft. above airport elevation unless restricted to a higher altitude in the Circle to Land minimums section on the approach chart)
