Default poor lateral control on a slow tow?

Have fun Cookie, but until you teach them to draw force diagrams, you
will have frustrating conversations.

I am a practicing aerodyanmicist, but will refrain from speculation on
the tow conditions discussed here. But I will suggest to anyone
trying to figure out what the required lift is, that they draw out the
forces in what is known as a force diagram. Also known as a free body
diagram. http://en.wikipedia.org/wiki/Force_diagram

In un-accelerated flight, which includes aerotow at a constant speed
and climb rate. All the forces, including gravity must add up to zero.

yeah.........this has really branched into two discussions........the
forces of flight, and why a slow tow is bad.



but force diagrams make it really simple to visualise what is going
on. But on tow, with down wash and vortexes and stuff it is hard to
figure what and where the forces really are.


(remember the discussion on "gravity power"?)
