Aircraft roll like they're on springs

To add to this reference my video OP, I don’t have any on.

I’ve flown the warrior (and a few others) a fair amount irl as well and I echo your sentiments on the FM. Applying roll is a very “On/off” motion with little feeling of inertia building as roll rate is applied.
How do you find the pitch/lateral axis in the sim?

Try the 748 and you will definitely not complain about the lack of inertia :wink:

It’s not actually inertia in the 747 (or most aircraft in FS2020), the control surface movements are delayed after joystick input to give the impression of inertia.

Can’t confirm. Still a lot of inertia if you remove the artificial delay.

0 inertia modelled on my version. Haven’t found a way to remove artificial delay using the gui.

Apparently we are using different sims. You can’t remove the delay via the GUI, you need to modify the cfg file.

What aircraft ? You play keyboard ?

I’ve seen it with Pitts’ aeleron. I know the feel of it, as you describe it. When I bank left and then key right very short, just tap the key, banking angle just seems to stop increasing suddenly. It keeps the same banking angle. With Pitts, the issue becomes less prominent when I put 70% authority for aeleron. I play keyboard only, no controllers here.

In my case, I’m not sure if this is a sim error. Else I would have put a complaint. Pitts is a wild thing with very direct control. My C152 does not behave like this, when I shortly key right, the left banking increase is decellerated, it does not stop ! So for other GA I cannot confirm. I’m going to watch for it.. but I think it is a keyboard issue. What keyboard repeat rate did you set in Windows.. mine is always max, because I edit a lot.

not keyboard - yoke

I agree, the flight model is a work in progress. The constant bouncing around like you get with bumpy summer air is a bit annoying. You never seem to get the nice smooth air that you find when flying in winter. Also, the banking behavior is not realistic. When you let go of the bank in most aircraft, they naturally want to return to straight and level flight, but in MSFS (and other sims) they seem to hang in the bank. They also don’t “shoulder in” or nose down in a bank correctly when all the lift disappears from the wings. I suspect this is pretty hard to code in a flight sim.

this is what i see. I never had this problem with my a2a aircraft in FSX or P3D.

I’ve noticed that it helps if I turn the sensitivity on the yoke down a little and increase the deadzone to about 4%.

Lol, if you are really adventurous you should try to dutch roll ANYTHING in a sim. Tried to do it with two T-tail jets in both MSFS and XP11, (both have low dihedral wings) and nope. Not happening…

It’s probably the reason why yaw dampers are never quite right. It used to be a very common practice by addon devs to just engineer the yaw stability into the flight model and make the yaw damper do nothing. Since nobody notices :wink: Might still be the case now.

Thanks for the idea. Going to try that next flight. Here’s an explanation.

This is certainly not always the case. It depends on the aircraft type, on most aircraft you actually need to steer slightly opposite the direction of the turn as soon as the desired bank angle has been reached. Reason for this is the outer wing having a higher speed compared to the inner wing, therefore the difference in lift cause the bank angle to keep increasing if nothing is done. Depending on the lateral stability of the aircraft this effect is compensated for or not.

I have not noticed. I fly the Stearman mostly which doesn’t have a swept wing. I’ll watch for that in the F-22 or Eurofighter. Thanks.

You should not notice anything in either of them since those are fly-by-wire controlled with a lot of flight augmentation built-in should be automatically compensated for.

I was thinking the same, but I am not sure how well fbw modeling is implemented in the sim. The F-16 module in DCS is the gold standard for me when it comes to fbw modeling. Is there a particular module that exhibits this behavior?

Those aircraft won’t even be able to fly without computers because they are inherently unstable. Subsequently the flight behavior of any fly-by-wire jet fighter is determined by software. Since continued roll when making a turn is not exactly beneficial in a dogfight (neither is rolling out) I assume those effect are automatically compensated for and pitch and angle of bank are automatically maintained.

Yes, I am familiar with fbw systems, but if I want to test the dutch roll in MSFS I need a non-fbw module with swept or dihedral wings. My beloved Stearman is flat up and down. I’m definitely going to check this out with the other modules.

CJ4? Although not exactly swept wings. Longitude if you have that one, maybe Boeing 747 with YD OFF?
