How much extra fuel can be uplifted?

[new_era]

Vilas,

Thank you very much for explanation. I’m on the 737NG. I got your point now about the limitation. Yes we do have also these performance limitations (field length, go around, obstacle, …) and the structural limitation.

Please! Please! It is not about cheating or doing illegal thing.

As AerocatS2A said it is in the case that refueling is completed and you expect to land at mlw (performance or structural)

Consider my following example (original post figures) considering ONLY structural limitaion:

zfw…61

fob…15.4 (13.5 +1.9)

tow…76.4

trip….10 (FL350)

ldw…66.4

Then you have last minute 4 pax (90 x 4 = 360 kgs) Is it arithmetically and legally possible to take them? YES

How? Change to cruise at FL 310. Rule of thumb, if you fly 4,000 ft below the optimum you will burn roughly 5% more fuel (FPPM p2.1.1)

Figures become:

zfw…61.4 (+4 pax)

fob…15.4 (13.5 +1.9)

tow…76.8

trip….10.5 (FL310)

ldw…66.3 (even less than mlw)



Now please tell me, where is the cheating, where is the illegal thing on it.
