Have any of yall had problems with the A321 not being stable? I’ll climb up to 33,000 and it will keep banking left and right trying to maintain a course. This happens primarily when I’m using LNAV.
Could be because LNAV is trying to hit the centre and just misses the pink line. Try turning off LNAV and use the old HDG button to hold your course.
Also, the A321 was reported to have not the best in-game performance, so it could also be that.

Being to heavy or fast can also cause swaying or “turbulence” of some sorts also

A321 is the most unstable aircraft in this platform it not only has the banking problems its also unstable during retract and extension of flaps. Hope a321 neo comes fast so that this aircraft will be no longer used by all of us

The swaying left and right is a bug with the A321 not the LNAV trying to stay on track, a temporary fix is putting flaps 1

How is increasing lift going to solve a directional issue?
It’s a bug…. It’s not LNAV over correcting.
Again, how could more lift solve the directional issue, I think you’re mistaking this with the pitch up and down issue and then stall when flying this aircraft.
Flaps can help stabilize the aircraft especially banking.

might be too heavy

a321 is not very well handling in game, but i think its better than a few years ago. What % is your load, and what is your cruise speed as a mach number? a321 cruise between M 0.77-0.8, its more stable at higher speeds
Had it at about 71% load and then cruising at M 0.8
So it was heavier and maybe descending could help too
then honestly there’s no excuse for the instability lol. IF has not represented a321 too well. game issue, not user. would say best chance at resolving your issue is cruise even lower

That shouldn’t happen, guess it’s a good excuse to ask for an A321 rework.
Again its a BUG. The aircraft isn’t stalling or trying to over correct itself in anyway. It’s simply a BUG and for some reason flaps 1 stops the aircraft rocking side to side. BUG not physics.
A rework is needed then, and more liveries.

You can use this table I made to determine the maximum cruising altitude for your takeoff weight in the A320/A321: A320/A321 cruising altitudes - Google Docs
For example for FL330, your TOW should be less than 90 tons, then you´ll have no issues in IF.

Actually, what your saying here is quite contradictive.
Because what does flaps do? The answer to that gives you the reason for this behaviour :)

When the angle of attack is pushed too high for the particular aircraft model, any will exhibit some such similar instability.
I have the recently re-worked C208 running in front of me now. I put it at high enough altitude, and high enough load for the speed, that it pushed the angle of attack up quite high, though still flying at stable airspeed and altitude.
I have it on VNAV and the wings are rocking back and forth just like the A321 (I dialed up the gusts and turbulence a bit to add to the instability, and I slid the rudder to the side once to help kick off the wing rocking).
Just before testing the C208 at such a stressed AoA, I did the same thing with the A380: on LNAV, and again, put enough combination of weight and altitude to ensure the AoA gets “stretched” while still being able to maintain constant altitude and IAS, and same wing rocking.
To the extent lower flaps decreases AoA it seems to help similarly to lowering the AoA by lowering weight and/or altitude for a given IAS.
But at high speed of course, flaps is a “cheat” (structural stress etc.).
There were some subtle sensitivity differences with how the above factors played out between the 3 different aircraft (A321, C208, A380) but the general idea seems to fit the overall experience:
don’t get so high, heavy, and slow enough that the AoA gets stretched out too high. Or the wings will rock (sometimes with a bit of induced stress).
