What context did I miss? The above quote was reply to simple question by me - are you saying AFT makes no difference to agility?
Regardless what the physics are, the practical bottom line is that empty AFT is easily the best config for dogfighting agility. Including off the wall maneuvers like flying sideways and back again for shots you couldn't otherwise get. You can maneuver over departure limit much easier without aft fuel. Agility benefits just keep growing as total fuel drains, but aft is by far the biggest positive.
And I'm pretty sure AFT is the biggest tank. Unless you meant that the other three together add up to more than AFT.
A contradicted absolute.
I do strongly personaly feel in AH that (1) it makes _barely_ a noticable difference [it _is_ noticable, and a most notable hinderance in a situation I avoid at most costs and the most likely outcome to a fight starting with me being low, slow n heavy], (2) especialy in comparison to the much more signifigantly notable impacts to performance and handling obtained by draining either of the other three tanks it also has, (3) which I admit is in stark contrast to logic or historical accounts of how of all tanks it had the most notable impact on performance when full or empty.
I agree, the practicality behind draining it first is undisputable, and I am aware that the aft tank is by a signifigant margin the single largest internal tank in the aircraft. My honest opinion is it seems, in comparison to what was described by pilots that tested the aircraft, our aft tank is too light when full, and too heavy when empty, but this is another gut feeling that if anything has already been disproven with heavy research into the matter already on weights and the CoG in a 152 earlier in this thread.
