Easy one...(Sorry, it is if you're an Aero E nerd wannabe, anyway. Found this in an Aero E text book some years back)

I'm sure there will a tweak or two added by a real Aero E soon enough, but essentially it's this: Split flaps create more lift than a simple hinged flap (aileron) for the same surface area. When using "aileron" in that config you essentially have a split flap acting in opposite directions on each wingtip rather than an aileron as we know them.

Do I get a cookie, or perhaps a star on my test to show mom when I come home?
