I would like to know what this forum thinks in terms
of this? In my experience, quite a few gliding instructors
are either very much missinformed about the aerodynamics
of lift (and keep on missinforming students), or offer
explanations that while accurate fail to answer a student's
question by advancing the understanding of what take
places. This is very discouraging for most people and
it is only the few who will then go back into the literature
and try to sort things out.

The funny thing about this is that, while it is not
very important to know about aerodynamics to fly a
glider, all sorts of misinformation eventually trickles
into discussions and advice about such things as the
best bank to turn in, or when a stall occurs etc.

So what should we do about this?

I agree with your statements.
When do your instructions begin?
I regularly abandon wrong assumption. Through this process
I am learning. For example the lift equation
CL * V^2 * area / density , how does it fit into the circulation
equation? I assume it was a stripped down version that I have
seen in an earlier post. I view the circulation as a 3D flow
about the wing and glider structure. As this flow must effect
every thing in one continues interaction, to express this in
a formula and still have a visual understanding of the process
must be nearly impossible. As a person interested in
aerodynamics I find the incremental approach much more to
my liking and I get results that are still within what I experience.
