:white_check_mark: REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue.

For the A320neo in FS2020

1.Start Flight Simulator
2.Select Free Flight
3.Select the A320neo v2
4.Spawn either in the air, or at gate, or on the runway
5.With the autopilot off, and flying straight and level, move the stick left or right less than 5% in either direction to try and start a slow roll.

For the A330 and A400M in FS24

1.Start Flight Simulator
2.Select Free Flight
3.Select the A330-300 passenger variant (RR), or the A400M
4.Spawn on the runway
5.Take off
6.With the autopilot off, and flying straight and level, move the stick left or right less than 5% in either direction to try and start a slow roll.

:white_check_mark: YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

  1. What peripherals are you using, if relevant: Virpil WarBRD Base, Virpil WarBRD Stick, Thrustmaster TWCS Throttle, no pedals, DelanClip TrackIR via OpenTrack

  2. I use DevMode, I made no changes in it

  3. DX12

  4. Nvidia RTX3060Ti

  5. i5 12400/RAM 32GB 3400Mhz

How to read the graph in the top left: Blue is pitch axis deflection, Red is roll axis deflection.

A320neo v2

How to read the graph: Black is roll deflection, and it’s the only axis I’m moving enough to be noticeable on that graph.

Even though I don’t have any dead zone set in my curve, I have the same problem, there is a deadzone in the roll but whenever I switch to Direct Law the deadzone disappeared

I`m using the Thrustmaster Airbus Captains pack, and had similar experience in the A400M.
This makes it very jerky to control on approach.

The Airbus A400M has a roll rate of over 30 degrees per second, whilst most commercial Airbus airliners are only around 7 degrees of roll per second. The A400M feeling “jerky” may be due to this dramatically increased roll rate in the real aircraft, which is accurately modelled in the aircraft in MSFS 2024.

I have real life experience flying the A400M Level D Full Flight Simulator.
The A400M has a MAXIMUM roll rate of 30 degrees per second. which depends on the law the aircraft is applying on that particular moment (TACT, NAV or LS). For example, when flying low level on TACT mode, this will definitely apply, but not when flying a normal ILS approach on LS, where the controls are pretty much as smooth as any other airbus, unless a hard, or even a full deflection of the controls is applied, then you get again those 30 degrees. I guess we could say the roll rate is not lineal but exponential, while the Ini A400M looks completely lineal. I would say the roll is way to sensitive while in normal law. IRL the TACT button activates this FBW state and for example would also inhibit most of the EGPWS callouts (imagine flying 150ft through a valley with the too low gear warning buzzing your ears). I’d like to see this simulated at some point.

Hi @S4NT0SS6368,

Thanks for the further information provided about this. As you can imagine, with the A400M being a military aircraft, a lot of the very in-depth system logic is likely to be strictly confidential. If any features may be missing or not accurately modelled for this specific aircraft, it could well be due to that factor. That being said I’ve passed your feedback forward, so thanks once again.

The MSFS Team

I totally understand. Hopefully with some more feedback, we can make this a really good rendition of this awesome aicraft.
