I understand how positive dihedral helps dynamic stability in

pronounced negative dihedral -- the wings have a noticeable downward
slope.

Q1: Do those airplanes need active fly by wire controls to maintain
stability, or is something else at play that keeps them right side up?

Q2: Does anyone have a design rationalization for such a
configuration, as opposed to just zero dihedral? I can appreciate why
fighters have it -- they exploit lack of aerodynamic stability for
rapid maneuvers -- but transports that spend their whole life being
straight and level are another issue.

Negative dihedral provides a place to hang bombs ala the USNavy's A-7
Corsair II.



Uh. OK

That's not compulsion, fjukkktard.

Sure it is Squirty the ****drip, you just can't stop.

People, if you are going to answer any of the AUKk00ks, remove any mention
of any NG with the word "kook" in it. The AUKk00ks are actually harmless if
left to themselves.

Uh. OK

Well just think how embarrased you would be if you had the bombs on
the top of the wing.

You have me there.

With all of the expert* pilots here, why would bombs on the top of the
wings be a problem? Go inverted, much better visibility toward the
ground then, right? Then release, they'll fall away.


*Expert: you have to take the word into its component parts: Ex is a
has been, and a spurt is a drip under pressure.

Hmmm. Our plane has positive dihedral and 2 hard points on each wing.
