A320 Rolls left on retard and flare

I have this issue, I will use the approach speed calcd in the FMC and/or TOPCAT, which is always above stall (checked just in case it was a calculation issue) and as I get close to ground I am fighting the plane to stay level

If I wait until the retard call-out it seems to get worse . I’ve been cutting the throttle before the call-out and then the left roll stops immediately and I can land without issues. It’s not standard procedure but I swear that left roll gets worse the closer you get to the ground if you wait to retard throttle at the call-out. This happened last night I believe in a 4 or 5 kt headwind, should have been a perfect landing.
Still , I have a lot more landings to try before I can say with certainty.

The retard reminder callout comes always on at exactly 20ft during a manual landing.
(10ft during an autoland IRL).

It’s just a reminder, nothing else.

If you are fast you have to reduce the thrust to idle way earlier, if you are slow you might need to keep some power on almost to touchdown.

I can’t same I’ve noticed much difference from retarding the thrust levers at the call-out to retarding them at 30 feet or even earlier. But I’ll keep experimenting.

Yeah I’m new to airbus, always did the 737NGX and ZIbo boeing for years. I use TOPCAT to calc approach speeds and reference with the FMC, I don’t know how accurate the FMC is in the a320nx even when inputting the weights and fuel etc. Last nights somewhere around 145kt i believe

But regardless, I seem to gain a lot more control of the roll once i close the throttles, up until that moment it really feels like a fight to keep it stable. But this could even come down to my controller sensitivity, more work is needed on my part.

145kts is a fairly typical VREF in my experience (of the FSLabs Airbus at least!). The MSFS Airbus (with the mod at least) seems to be getting better at calculating sensible VREFs - it used to frequently tell you to approach at around 160kts, which I’m pretty convinced was always way out. I tend to just go with what it calculates though, in the hope that it knows what speed will help it to land without rolling about wildly!

Just happened to watch V1_Simulations stream, i timestamped the 1st landing attempt before he goes around, basically same experience I’m having but to varying degrees

“When it rolled to the left i literally had full right sidestick input”

Yep, exactly the same here.

16/10/2020, the problem stay the same…
We have to contact them, because we can’t fly with this issue
In my opinion, they’d better fix the different major problems rather than creating new scenes (Japan for example), because we won’t feel like flying if we’re going to land like a stone at the end of the flight.

same with me

This is a known bug of roll control loss since the first launch of the game. You can better experience it when you manually land the plane. As most of users use autoland, the bug doesn’t have big effects (and can even not be seen). It doesn’t depend on your speed, CG, weight, etc . However, it seems to be related with the fly-by-wire system as turning off FCTL buttons on the overhead panels make the bug somehow diseppear.

From my experience, the rolling effect bug occurs more or less depending on how you were manually (or the autopilot) rolling your plane just before touchdown (to keep be aligned for example). To avoid it as much as possible, you have to be straight before the flare. It can roll on the right or the left, for example, if before touch down you input action on the roll axe of your controller/joystick, etc.. then depending on how hard the input is and on which direction, the bug will increase this rolling and not let you control it. If the rolling bug is not too hard, you can counter it by fully input control on the opposite direction.
I hope I was clear ^^’

Please, be sure to report the bug and vote so that this issue can be resolved as fast as possible. It’s becoming really frustrating and annoying not to be able to land right and not to be able to fully control your plane when landing.

your premise is wrong, most people don’t use autoland, because it is so unreliable if you are constantly venturing to new airports thus are unfamiliar with how well it works there or even how well the ILS is aligned and what it dose in the last in the last stages from ~300ft AGL downward, or even if it has ILS at all.

Furthermore the MSFS A320 can’t autoland. It continues down the glideslope until it hits the runway.
No flare, no thrust reduction.

A cheap C172 AP does the same ‘autoland’ if it has an approach mode.

Yes, I don’t know how people are not talking more about this issue, I’ve not been able to fully enjoy flying with the Airbus because of this very bug. A complete loss of control input right before touching down is not something that should be ignored as it seems to be the case as of now… Other thing that I noticed is that this issue doesn’t seem to happen when you don’t touch the autopilot at all.

That’s so weird. I’ve flown now 10 manual ILS approaches with varying speeds from VAPP to VLS -10kts and full aileron deflection above and below 50ft.

Couldn’t trigger the roll phenomenon a single time.

I will correct : Its seems that most people of the sim use autoland. Just read comments on different topics when they talk about landing or share videos, you see that they often use autoland, even if it’s broken, not flaring and not aligning (depends on airports). You can even observe that on multiplayer and often see people crashing on landing using it. I may be wrong, but it’s a lot of clues.

The speed doesn’t matter, it’s when you are approaching the ground. Could you share a video ? Also you can try triggering it by rolling a little when the flare moment arrives for example.

As I said, if your plane is straight and stable before the touchdown then it won’t happen but when for example, in turbulent/bad/windy weather you are trying to keep your plane align as much as possible with the middle of the runway during the final and until touchdown, playing with the roll axis then you can notice the bug.

If needed, I can show you both cases.

As mentioned above. I’ve tried from 100ft down to 30ft with full left/right sidestick deflection to provoke this problem.

Share a video please. Maybe there is a misunderstanding. I’m gonna share 2 vids I just recorded.

What kind of misunderstanding? Sorry, I don’t even know how to record a video.

On how the bug occurs. I’m french so my english may not be clear.
Try geforce experience it’s easy, because we need to see how it doesn’t occur with you when with everyone else it does.
