Dear all,

I posted the fuel sequence, taken from the actual B-52H Flight Manual for the ones who like to fly “by the book” so, this is not a solution for the amber wing tank warning light issue. On my side, I have no problem with that amber light, up to now, it does what it should.

As per the B-52H Flight Manual, the green band on main 1, 2, 3 & 4 fuel quantity gages means “safe to use fuel from outboard wing tanks and external wing tanks”. So, in real life, you do not use fuel from wing tanks and external wing tanks (of a particular wing) unless you have reached the green band on both main tanks of that particular wing.

Another interesting paragraph tells us what could be the reason for this. It goes like this: “Fuel must be used in accordance with normal fuel management sequence to attain maximum airspeed capability. To avoid wing flutter at speed less than 390KIAS and .87 Mach indicated, fuel in the main tanks must be used down to their respective green bands, as marked on the fuel quantity gages, prior to using fuel from full outboard wing tanks or full external tanks”.

The B-52H is available from Mach One Manuals. Usually, I try to read from the first page up to the last, but this manual is 1148 pages. Only one part is missing, Appendix I Performance Data. That part is on a separate document. Appendix I is use to compute S1 speed among others.
