For the 747-400
Va (Design maneuvering speed) is 330 kts at sl, 334 at 10k,
358/.92mach at 29,000
..so yanking the stick into your gut for a snap roll at 330kts,
means no

This looks odd from an external view standpoint. It seems like we'd
want a slight amount

Wasn't sure but it sounds like you are using the autopilot's alitutde

FYI: 490 KIAS is way too fast for most big jets under *any*
circumstances.
Yes, there is a similar problem at mach 0.8 ~ 0.85 as well though. And IIRC
at altitude as well.
Best,

From what I can find, the 747 is supposed to be able to cruise at
around 490 KTAS

So basically, you have the plane in an unusual flight environment.
Real planes are almost never flying this fast at this altitude;
they'll be at ~300 KIAS or so and using the extra available thrust for
climbing.
Counter-example: a few years ago, I flew from Ottawa to

If you're trying to fly at 490kt *indicated* at FL180, then you're
pushing something like 666kt true -- it would be no surprise that
you'd have to push the nose down and abuse the engines to maintain
that.
You also have to allow for compressibility effects in
