There's a great deal of debate in this part of the world at least on the
issue of which control to use to pick up a dropped wing.

To be honest, I don't see much debate in that thread. Sounds like
pretty much everybody is saying the same thing I am -- that rudder is
the right thing to use to recover from a wing drop during a stall.

I've not really thought fully through the arguments.
Is yours simply about control authority or is there more to it than that?
Perhaps we should take this one out of .ifr?

Yup, control authority. That's pretty much it. The rudder has control
authority over a much wider range of conditions than the ailerons do.
When things are happening fast, you want to have a plan that always
works, without having to put any thought into it. Hence, my
recommendation to use the rudder to maintain heading.

This started in .ifr because we were talking about how to control the
plane in IMC with no gyros. The basic assumption is that you've got
*some* heading reference, be it the wet compass, the ADF pointing at a
distant station, or a GPS course line. Even with the GPS (which is by
far the most useful of the three), you've got limited information, so
your best plan is to stick with something which always works, even if it
doesn't work very elegantly. That's the rudder.
