ft, did you not replicate with
Rainboe,
todays nitpicker comment: In a vertical climb most aircraft (which have cambered wings) will in fact have a zero-lift AoA which is negative rather than zero, giving you a few additional degrees nose down relative to vertical to add to those caused by the angle of incidence.
with what I wrote in the previous post:

?

We can produce all sorts of fancy formulae (which really won't mean anything to anybody without a diagram!), but the answer will be- AoA will be in proportion to Cos climb angle. A 15 degree climb will have .97 of level flight lift- you know it, I know it- I feel it in me bones!
