Thanks Yipoyan, I hardly ever use the FPV either save for using weather radar in the climb, pitch attitudes have always worked for me, and numerous people before me still. All I was getting at is I'm not so sure your method is entirely accurate, as NSEU has also suggested the wing incidence to the fuselage is the missing element in that equation. Whilst it may be quite small I'm sure two numbers on the same order of magnitude could produce noticeably different results when it comes to flying or measuring AoA. I think what you wrote is a good idea but it doesn't appear robust enough other than to show a change in AoA since the wing incidence is constant for any given configuration. However in the scenario referred to in the opening post I'm with you in that I'd rather set an attitude for clean speed and deal with the numerous more important things that ensue than trying to figure out how to get best AoA.
