With the lower boost rating the A5 outclimb it and out run it, meaning, you can BnZ a spit 5 for a long long time if you have the patience, taking very little risk.
Not unless you start the engagement with a considerable amount of E advantage in the firstplace - which, unfortunately is the prime reason why 190 pilots will most likely to choose to be up higher than everyone else, be it AvA or MA alike.
At co-alt, there's simply nothing a A-5 can do with any kind of maneuvering that might be called 'aggressive'. Forget the vets or experten jabbering about how they force overshoots with rolls and scissors - in most cases they have a bad bad habit of forgetting the quality of pilots they face. If dancing around a baby seal who couldn't find his butt with both hands count as 'outmaneuvering', then I can do that too. However, against anyone with just the basics of air combat into his mind, and all 'maneuvering' is simply out of the question in a 190. The 190 is literally the worst maneuvering plane in the entire Fighter category. The plane simply cannot handle anything else except diving and rolling.
Outclimbing a Spit5 in a 190 is hardly worth anything in practical combat, since even if you can draw him into a climbing chase and have gained some amount of separation the 190 just cannot go into an extended rope-a-dope from climbing speed, as the plane will fail to respond and viciously stall out once the speed becomes low.
Whereas, the Spit5 can hang on a thread and lob Hizooka shells upto the very last moment. Even if a 190 miraculously succeeds in a rope-a-dope, and manages to tip over and nose down from the vertical without being shot, the odds are that the 190 needs so much speed to recover to start maneuvering again, that while the Spit stalls out, quickly recovers basic maneuverability at around 80~100mph, the 190 will be forced to 'fall from the sky' until the speed is regained around 200mph. The 190 will overshoot the Spit floating around below him, and then bam, end result: the Spit is still behind your tail. Any kind of premature attempt to correct the plane's position/aim will kick in the destabilization.
There is no such thing as 'maneuvering' in 190s. It was a long time ago, but I still remember Grunherz, a skillful 190 pilot himself, spitting out a frustrated remark; "there's nothing a 190A can do against a N1K at coalt".
What you can do, is just run. Keep running until out of visual range, climb up again, and then re-enter combat at a hgher alt. It's the only logical thing to do in 190s - and when people do it, they are ridiculed and laughed at as being a "timid Bore-n-Zoomer".
Frankly, against any plane that is faster than itself, and is able to catch up with it, 190s are just helpless.
