Re: Campbell's even crazier than a MANIAC? (archeopteryx climbing)

In general, its more efficient, that means a glider could glide more before having to climb a tree again, saving time.
You can produce the same amount of lift, with less drag, giving higher max glide speeds, better headwind penetration, etc.

Max glide speed is dependent on wing loading, not aspect ratio. Same with wind penetration. But the efficiency point stands. Of interest to planform evolution considerations, I note that Microraptor has rather high AR wings, while Archaeopteryx has a planform with a much more moderate AR.
