In a coordinated turn both wings are at the same AOA (please see my
reply to the other post in this thread). In an uncoordinated turn this
is not the case. Think of the direction of the airflow over the wing -
in a coordinated turn the airflow is always from the same direction
regardless of position on the wings; in an uncoordinated turn this is
not so, hence the AOA will be different. I was talking about
coordinated turns only (and I presume you were too in your original
post).
Hmmm...a little history. All of this argument came up
because we were discussing spins, and a bunch of posters
were talking about skids being the cause, and some of
us (the other posters) thought it was more due to
aileron stall and different airspeeds of different
wings in steep banks.
So we're trying to calculate the magnitude of the
airspeed difference caused by bank angles in steep turns
with long wings, vs. that caused by skids. How significant
is a skid vs. bank? Is it a skid or an accelerated skid (coarse use of
rudder) that's causes these spins?
Clearly the effect of bank on precipitating a skid
is a little surprising to other posters as well. It
was interesting and novel to me as well a few days ago...
