Situation - 2 x C130 AKT to Tabuk G1 supplying fast pointy things with bomb tails, I was operating the second. Presented with satisfactory trim sheet, fuel flow ignition etc. During line up, cable raised so taxi fwd because the book said we could.:)

Mission - Clear Take off and away we go.....bit slow on acceleration but seemed OK, V1 then VR but quite close to the end of the runway and a significant pull force required to select the attitude - bit odd.:rolleyes:

Execution - Managed 2 cups of tea as we staggered towards cruise alt which was well bellow planned level. Lot of furious number checking all around leading to the conclusion that we were quite possibly operating a little above MOS limits:eek: Oh and we need wing relieving fuel which we do not have :uhh:More number crunching decision to proceed to Tabuk as least damaging option.

QuestionsMk1 bomb tails are 50% lighter than Mk2 bomb tails and good old movers used wrong figure and did not check weigh load.:ugh:

Lessons Obvious really, never assume........
Happy flying!

I seem to remember this too..pity the RAF never used the acceleration check time graph in the #1#1. Everyone else on the planet seemed to use it but Lyneham seemed to know better...

Thanks Mogwi, you were there - Although in my defence, the RAF webpage does say Paras, I checked there first!

Not sure an acceleration graph would have separated the Hercules "stunning performance" with this scenario near the WAT limit but you never know!
