I think it's the Russians who have a combined G-meter and AoA gauge? For max perf in the turn, pull to the +G limit until that corresponds to the max AoA limit as IAS bleeds off, then maintain that....
Playing with the Aggressors at Alconbury in an F-4, I once went vertical, looked back over my shoulder and suddenly felt the rudder pedals shaking... I had rather more AoA units than IAS
. Fortunately the recovery drill worked fine without any dramas, but the Aggressor chasing me later told me that the contrail looked rather like something launched from Cape Canaveral!
