I've seen 747 using both the ailerons and outboard spoilers for roll
control. However I've never seen the aileron-as-flap thing until I saw
it on the A-330. And I'm quite certain that B-737, 747, 757 and 767
don't do that. Nor do I think A-320 families do that either. I've
been on a A-340 once but I didn't pay attention to the control
services, it probably does it just like A-330. Never rode on a B777.
