Hmmmm, I could have sworn I remembered the outer spoiler coming up in conjunction with the airleron for larger control inputs....

You're right about one thing though. The ailerons are the first thing to move followed by the spoiler to assist the roll. I was remembering it back**swards. But I'm still pretty sure it was the outer spoiler that is used for roll input assistance. The inner to outer progression was for speed brakes I believe. And then on touchdown they must have some sort of "Big Red Switch" that snaps the whole lot up on landing....

I'm flying again in March I'll have to watch more carefully.
