Thanks for the comments.

You wouldn't believe how much time I spent on the first few slides of the
Lift / Drag lecture, the bit covering how a wing generates lift, to try to
make them benign with respect to controversy but still say something
useful and meaningful.

Kevin, when I get a chance I will go back and review the streamline and
force diagrams on pages 7 and 8 of the Lift / Drag lecture. *It does look
like they might be slightly erroneous, but I just want to check back
through the literature and dig out some experimental results before I make
any changes.

Bildan, with regard to yaw generating roll via dihedral effects I do
actually say that in the slide. *However the section on the effects of the
controls is going to get a rework at some point. *It's the only point in
all three lectures where the audience without fail zones out on you and
looses interest. *So I need to think up some way of making it more
interesting.

Richard

You're right, I seem to have missed the section on yaw to roll due to
dihedral. I apologize.

Just a thought. This isn't exactly fair - it's clear you spent a lot
of effort on the graphics - but just repeating the same graphics style
with minor changes with different text can be boring. There's an easy
way to illustrate slides and get more color and realism by using a
flight simulator like Condor. I think Uros would grant you the right
to use the graphics if you give full credit.

The flight sim technique is to set up a situation you want to
illustrate and pause the simulator at just the right moment. Select
the outside view you like then take a JPEG screenshot. The resulting
JPEG file can then be edited with a graphics or photo-editor to add
additional graphics or text. The result can be quite pleasing.
