Here is something that I have always wondered about, but have yet to
hear a good explanation for. Vx is the best angle of climb speed for an
aircraft. Vy is the best rate of climb for an aircraft. I can't seem to
visualize why Vx is not the best rate of climb.

Vy is time, and Vx is distance.

The key, Randy, is to look at what the definition says and consider the
words carefully. Best rate of climb considers feet of climb per unit of
time past, without considering distance travelled at all. Best angle of
climb considers feet of climb per unit of distance travelled, without
considering time at all.

.....To my feeble way of thinking, Vx - the best climb angle -

NO. There's part of your difficulty, possibly. Stick with the proper
terminology. Don't switch words around, because they mean something. "Best
angle of climb" is not necessarily the same thing as "best climb angle".
