Good Morning LM,
Not right now thanks; the player (??) might get Yawn Coupling and Roll over in bed (especially the Dutch ones (where has Ton got to??)).
How's the pin,; did the PK+ZZzz work OK?

If lateral stability > directional stability = Dutch roll
If directional stability > lateral stability = spiral instability (spiral dive)
As altitude increases, lateral stability decreases at a lower rate than directional.
Therefore propensity to Dutch roll increases with altitude and spiral instability decreases.
Well, you almost asked........
Sorry - crossed posts

That would probably be a good idea, thanks!
Not really a stability thing, but I'm, sure the bird wing emulator man, Mr Bonney would have been fascinated by it. Have you seen this? (A-380 gust alleviation)
