Yep... the opposite of anhedral. Bonus points (anyone) if you know why some aircraft have anhedral.That's pronounced dihedral. Di-hedral. /dʌɪˈhiːdr(ə)l/

Brit forum members can weigh in on this one I`m sure. Today on the VFT.

Yup. Neutral or even negative roll stability makes for a more maneuverable fighter.Makes 'em more manouverable

So.... why would a huge cargo plane have anhedral?

Yeah... that extra measure of stability is ofttimes too much stability, requiring more aileron surface to roll. Snowball starts rollin'. Now we need a bigger vertical fin and rudder to compensate for the additional adverse yaw the bigger ailerons got us. Better to reduce the stability so's we don't need all that extra area in the wind.The high-mounted wing..........provides an extra measure of stability due to the "pendulum" effect.

. . . the Short Sunderland flying boat, despite appearances to the contrary, they were apparently extraordinarily difficult to shoot down. The Germans called it the Fliegendes Stachelschwein or "Flying Porcupine". I guess those Sunderland crews had an extra reason to fight back hard - if they bailed out, they were normally over water which could be far from land and/or infested with sharks etc.
Just had to repost this one from the great VFT site today. "The Aviator"
Was cleaning up my computer today 'cause the hard drive is full. Ran across these....
When I was teaching at AIM, I got the job of teaching the Air Force boys from Whiteman AFB so they'd pass their A&P tests. Being retired AF I was the logical choice I guess. Anyway... couple of the AF guys invited us out for a nickel tour of the B-2 Stealth Bomber. It's pretty impressive up close.
