On any standard light aircraft wing, all best climbs (rate of climb Vy,

causes the climb angle and rate to decrease.

Not on my 182. The manual says, and I quote...

Using 20 degree wing flaps reduces the ground run and total distance over
the obstacle by approx 20 percent.



Yes over an obstacle. But that is a compromise. On a short strip the
compromise is less climb for shorter takeoff distance.

Your 182 manual NEVER says that Vx is with flaps. NOWHERE!

Vx in a 182 is clean wing. Read the POH.

Yes, but just because a clean wing has a certain velocity that provides
the best rate or angle in that configuration (no flaps), doesn't
necessarily mean that this is the best rate and angle that the airplane
is capable of achieving in other configurations. I don't know why Vx
and Vy are provided only in the clean configuration, but that may simply
be by definition and may not imply that this is the best that the
airplane is capable of.
