Averse yaw is caused by the drag of the down-deflected aileron.
Assuming you have the correct aileron position for the crosswind, the
drag of the down-deflected aileron will help counter weather-vane.

In the B-17 if you used the wrong aileron you would not have enough
rudder to counter it...the ailerons on that airplane produce a lot of
drag.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

Yep, I got mixed up.

That's a bit strange. What is the "wrong aileron"?
Ailerons control roll, while the rudder controls yaw.

If you are "wing low" while approaching in a crosswind, it is possible
that the windward wing will dip and a spin will try to start. You need
to correct using the rudder, but if no more authority is available, you
have a problem. It's not specific to the B-17.

I'm referring to after you're on the ground...during rollout. I had a
"Captain" roll in the wrong aileron when the airplane began to turn into
the wind...things got pretty interesting for a bit. G

But not always, and not only. If you have an ASES rating you must be
familiar with the use of ailerons for steering on the surface. You also
should not overlook the necessity of using rudder to control roll in
high angle of attack on swept wing high performance aircraft, while
avoiding the use of ailerons.

Perhaps you are more familiar with the specific characteristics of B-17s
than is Maule Driver. If so, by all means tell us about it.

Do you notice the apparent contradiction between your statement in your
first paragraph and your claim in the second paragraph?

Which two paragraphs? mine or Maule Drivers? G
