No idea on where the Bow Air Attack is. Maybe it's a bit on the obvious side so they didn't feel the need to explain it?

Speculating a little, here: Maybe it's a full-charge attack. Whatever shot type your last charge is, it'll send those arrows flying at the wyvern. It could also be an arrow slash. I really hope it's the arrow slash, personally, or the ability to do both.

Speaking of which, I really want the arrow slashing to be improved a bit. I'd like to see an upward slash after the two middle strikes. Would make it more useful for cutting a pesky Rathalos tail.
