Due to reduced performance margins, the use of maximum effort speeds during landing when the aircraft is limited to ___ fpm may result in an airframe overstress condition.
300 fpm
Where should the aux tanks and external tanks be prior to landing?
Aux tank = no restriction
External = ~empty (<= 500 pounds)
Tank Limits
-Outboards
-Inboards
-Total Main
-Aux
-External
-Total without fuselage
-Fuselage
-Total with fuselage
-Outboards = 8310
-Inboards = 7650
-Total Main = 31920
-Aux = 5810
-External = 8900
-Total without fuselage = 61,340
-Fuselage = 24,390
-Total with fuselage = 85,730
What are the three categories of fuel management?
- Primary
- Alternate Enroute
- Secondary
Explain primary fuel management
- No. 1 and No. 4 always contain 500-1000# more fuel per tank than No. 2 and No. 3
-No less than 7060# in No. 1 and No. 4 and no less than 6410# in No. 2 and No. 3 when externals contain usable fuel
Explain alternate enroute fuel management
Used to maximize weight in outboard tanks during long transit legs, potentially extending airframe service life
-When external/aux contains usable fuel, No. 1/4 are kept at max and contain 500-1000# more than No. 2/3
-Once external/aux empty, use No. 2/3 down to 1520, then use 1/4 down to 1520
-Once all tanks at 1520#, go tank-to engine
Explain secondary fuel management
Any fuel management that fails to meet primary or alternate enroute
This will occur when there is usable fuel in the external tanks and the main tanks are partly filled to less than 26,940#
An extreme deviation is operation with No. 1 and No. 4 empty
What are the G limits for area A (Primary Fuel Management with externals and pods)
Up to Vh
-1 to 3 symmetrical
0 to 2.33 rolling
Vh to Vd
0 to 2.5 symmetrical
0 to 2 rolling
What are the G limits for area B (Primary Fuel Management with externals and pods)
Up to Vh
0 to 2.5 symmetrical
0 to 2 rolling
Vh to Vd
Same
What are the extra requirements to be 540 sink?
Gross Weight <= 142,000 pounds
Fuel in 1 or 4 <= 7,320
Fuel in mains <= 28,000
What gross weight range must you be in order to still make 540 sink for a main tank fuel of:
23K
24K
25K
26K
27K
28K
23K = Less than 142K gross weight
24K = 115K-142K gross weight
25K = 122K-142K gross weight
26K = 128-142K gross weight
27K = 135K-142K gross weight
28K = 142K gross weight exactly
NOTE: If more than 2.5 degrees aileron tab deflection is required to trim unbalanced fuel at speeds >200 KIAS, reduce Vh to ___ KIAS less than shown in Figures 4.1-1 and 4.1-2
5 KIAS less than advertised
If severe turbulence cannot be avoided, flight should be in the range of ___ KIAS above power-off stall speed for the operating gross weight, not to exceed ___ KIAS
65 KIAS above power-off stall speed not to exceed 180 KIAS

CAUTION: Since CG shifts with changes in aircraft attitude, if fuel is carried in the fuselage tank, the external tanks should be empty when the fuselage contains less than _____ pounds, or the aircraft is restricted to level flight until external tanks are empty
20,000 pounds
