Situation....
In a fight with a bandit. I am in a nose down spiral to the right with him but can't pull lead. As we descend and it is apparent a lead pursuit isn't possible, I nose down and roll right (usually 90 degrees) so he is off to left side then I pull my nose up so it is in front of his projected flight path.
I sometimes do this on a merge. Rather than turning in the horizontal I split S and pull up to where I think he will cross.
It works beautifully if I have alt. I usually miss as he flies right through my gunsight. What kind of maneuver is this, other than frustrating? Lol
