Aileron agressive

[CptSpeirs]

Hi guys

Is it only me? I think the aileron responsiveness is much more agressive then the pitch axis. I can barely maintain a smooth and stable approach when handflying. I have turned down the responsive curve but that doesn't help much. The plane seems to ignore very little movments on the aileron. I can fly other planes with same setup without any problems.

hello it is normal because the a400m is a militairy combat and air transport aircraft it is in real life also

Yes I know its much more agile then A320 for example. When I look at the flight controls page: I see very little movements on the aileron but the plane in the air moves at the same amount of aileron not a bit. And when I then give a little bit more then somewhere comes something like the end of a „deadzone“ and the plane „jumps“ a few degrees. Like I would have a deadzone in the settings and then a very high curve of sensitivity. Maybe it has to do with the FBW system…

The only thing I've noticed with the roll rate is it feels like there is no inertia at all.   As soon as you stop inputting a roll input, the aircraft instantly stops rolling and is held there. It feels wrong and is very noticable at slow speeds on approach when making small inputs.     ALL other iniBuilds Airbus aircraft I've tried DON'T feel like this at all and each have a slight ammount of interia after releasing the roll input.

I can't edit my previous comment.  

I've been watching the FCTL page while rolling.   It looks like after a roll input stops, the aircraft is inputting a small opposite roll input to stop the roll.   I'm assuming this is correct behaviour... it still feels wrong/weird.

Hi @CptSpeirs@TheEvilToaster

The primary flight control response, especially aileron roll rate and behaviour is set per feedback provided by A400M pilots. There is a bit more FBW-induced stability control on the A400M than the typical airliner which is what you're observing with the auto-correction behaviour.

We'd be happy to look at this again if more accurate references can be provided. Also just to be sure, ensure that all the other assists are disabled to avoid any conflicts: 

Thanks!

Thanks for the response. Yea, I thought it was correct behaviour, which is completely fine.  My only issue with it, is feel very aggressive. Instead of improving stability it stops the roll immediately and is too strong, maybe it could be reduced a little bit? It just feels like the aircraft is ignoring all wind and is perfectly stable, like, too stable -- You can just put a bank angle in and it just stays there.    Its makes making minor corrections on approach feel horrible and strange.

I do have all assists turned off.

@richboy2307: I made a video which shows my point. I absolutely believe that it is much more agile than a normal airliner. I think after the "deadzone" of the FBW system, the first movement is too violent.

Its sometimes overcorrecting but there is no input from the controller. And with the slightest manual input, the aileron literally jumps around.

And for example: In this video on the approach of a real A400M in germany, you see very smooth movements on the aileron.

Thanks for check this again and please reduce the first movement after the deadzone. Then it will be the perfect plane for me in MSFS 2024. 🙂

@CptSpeirs

Great vid mate, shows the issue perfectly.  Even if the roll stability is a feature of the real aircraft, it's currently overtuned in the sim and corrects/overcorrects/stabilises roll too fast and aggressively.  

To me, the only way i can describe it in it's current form, is it feels like I'm just rotating the aircraft model instead of "flying" the aircraft -- for lack of a better term.    It feels great when Direct Law is selected on the overhead.  

@richboy2307  I hope this roll stability can be tweaked a little in future.

@richboy2307 

I've made a quick video showing the deadzone and large, initial FBW spike that happens when you finally "overcome" the deadzone - It feels like you're fighting the aircraft as it wants to remain perfectly stable.  Its this inital spike that makes small corrections, such as on approach, very hard to do as more often than not the initial spike is larger than what you wanted to input.  This spike and deadzone only happens in Normal Law.

@TheEvilToaster: Thank you for your perfect addition!

Thank you for your contributions everyone, they're very much appreciated. I'll pass this on to the team 🙂
