Why not just say that in a crosswind landing, on final, you
always have to fly an upwind course through the air to
achieve a ground track aligned with the runway. Always.


Because it is not true...

More?

No thank you!!!
Obviously I lack the ability to explain myself well enough to be understood.
You see, english is not my craddle language, and I am having some trouble
with it...
And from other posts, as the one you don't see how a slip on base will get
you a longer final, I'm afraid that we have some confusion going here about
the manouever discussed. Maybe we are talking about different manouevers.
I'll try to make a diagram (one image is worth a thousand words...) and post
it somewhere.

Just for this one, I'll fall, though...
Imagine a runway, a left crosswind, for example, and you trying to land. If
your fuselage is aligned with the runway the wind will blow you to the right
of the centerline. You can turn left, into the wind, and then compensate as
you say. Your nose will point left of the runway, and your ground track
(velocity vector) will be aligned with the runway.
Or you can put the left wing down. The glider will try to turn to the left
(uncoordinated), but then you, as a savvy pilot, push the right rudder to
mantain the fuselage aligned with the runway. Ah and pull the nose slightly
up to compensate for the lift loss resulting from moving the lift vector
from the vertical when you banked. Maybe if you are already on the desired
glide slope, you will hide some airbrake to compensate for that lift loss
and not become one with the earth prematurely.
Well, now we are aligned with the runway, wind wing (left) down, right
rudder to mantain alignment... the wind drift now is compensated with the
lateral force produced by the banked wings. So you are not turning upwind as
you suggest, and your ground track is aligned with the runway. Voila!!!
When you are closer to the ground as to concern you, reduce the bank and the
rudder as fit. It'll be for a few seconds anyway.
I've used this technique many times. I have also induced severe slips to
augment my descent rate and make for steeper approaches into short fields
(outlandings) and with obstacles.

Anyway it's sunny outside, I'll be flying again soon! Suggest you to do the
same.
And sorry for the large post!
