Terry,

You've hit the nail on the head. I think this is reinforced by the fact
that there are many pilots who fly very, very well, but have built
their own successful (if not wholly accurate) models of flight and
airmanship. For example, I know pilots who routinely make expert
crosswind landings who believe the wind exerts force on the aircraft
while it is in the air and that by tilting the wing into the wind, they
are counteracting that force. The physics of the model is flawed, but
they are able to use it to fly with great competence.

The model they use, however, may not serve another so well.

I have a sense that airmanship and its teaching has yet to be fully
explored. Seems like a great Doctoral Thesis for someone with interests
in aerodynamics and pedagogy. Building an accurate aerodynamic model
tailored to serve the needs of aviators (as opposed to engineers) would
be a good first step. Next, application of the expansive work done in
instructional methodology to create a more efficient and effective
approach to teaching flying.

There's a certain charm in realizing we are only four generations
removed from the Wright Brothers. But that should also be a warning.
There's much left to learn.
