What would you suggest using, in a plane that doesn't have an AoA indicator (i.e. 99.99% of them)?
Well, 99% of the aero aircraft I have flown (and I have a bit more than 120 hrs aeros) do have aerodynamic indications that are pretty obvious if you are pulling some G and
this I would suggest is what you should be using here.
Another person cheesed off that this thread was pulled after putting effort into a reply!
