In ED 3rd edition how is a windling using Dive Atttack handled when having more than one attack? If he for example has second weapon is both his attacks damage increased through the talent or only one attack?

Yes, but in the paragraph just before which you didn't quote it mentions attacks, which is what puzzles me

That's because it will apply to any and all attacks that follow downward movement. i.e. it's not just the Swooping Attack ability that would trigger this, they *could* just jump down and not fly. I would suggest however that it only be controlled descent that allows this, so a falling windling (perhaps with wet wings, or on fire) would first have to gain control of themselves.
