I think you're leaving something out ... like the length of the flight.

If you're *only* going to fly long enough to consume that 700 lbs. of fuel,
then simply subtract the weight of the plane (B11), from the maximum
allowable landing weight (I8), to determine the maximum fuel to be loaded
(4357 lbs.), which is well below the maximum allowable take off weight
(20000 lbs.).

Am I missing something, or are you missing a variable (like flight length or
time).

I have a calculated weight <B11(given). I need to determine the max amount
of fuel ( ? )that can be loaded to satisfy a landing weight restriction
<I8(given) knowing the consumption <H11 (given) for a specific period of
time.
Basically, I want to know the maximum amount of fuel in lbs that I can put
into an aircraft, to fly a short flight, and not land above the maximum
landing weight of the aircraft.
<B11 ... AC Min ZFW lbs ( 14343 )
<L8 ..... AC Max Fuel lbs ( 6790 )
<I8 .... AC Max Landing Weight lbs ( 18700 )
<H8 ... AC Max Take-Off Weight lbs ( 20000 )
<H11 .. Fuel Consumption lbs ( 700 )

Hope this makes sence.... Thanks
