Airbus A320 No aileron control before touchdown

I think this depends on the different flying styles of different people, me for example, I always approach with autopilot and ILS landing at all times, and only disengage AP at 100 ft before touch down for manual flaring.

So any weather conditions like crosswind, is fully managed by the aircraft’s autopilot, so the orientation of the aircraft as well as the attitude to keep within the glideslope and localiser signal to be able to land on the runway is fully managed.

Since I always fly this way, it’s difficult to pick up any issues if it doesn’t happen to me because of my flying style.

Take the Nose diving bug for example. I just tried a CAT III auto-land to HK. Whenever the AP is engaged before touchdown, the AP will always dive the nose down to the runway to catch the dipping glideslope. And I can’t recover from that. So that’s an issue.

Then I tried the exact same approach, with a slight difference, still autoland, but with assisted flare to mitigate the bug, then I end up ‘fighting’ the autopilot for control and end up with a nose dive anyway since the autopilot wins, even though there’s a slight less bounce than the first trial.

Then the third time, I approach with the same method I always do, which is full autopilot approach until 100 ft RA callout, disengage AP and the aircraft is stable, I pull back the sidestick to flare and smooth touchdown.

Now, unless someone told me to test the autoland, I wouldn’t even think that there’s that issue since I don’t fly with that style anyway. Which is why I don’t get many issues such as these, because my flying style just seems to not giving it the opportunity for the issues to even occur.

Looking at You Tube cockpit landings most pilots use that approach, but disconnect the AP at a higher altitude.

I try to do the same and after a few go-arounds landed the A320nx reasonably well. Although I’m not sure the A/T cancelled immediately the throttle reduced to idle; she floated down the runway a bit before touchdown.

63

I disconnect 4-5 miles out, and always fly it down to the runway… Throttles only closed at Retard call.

Hi all,

Am experiencing the same problem. It always happens around 50-30ft above the runway; the aircraft will roll to the left and ignore attempts to correct the problem. Has led to some interesting “landings” . . .

65

It might be unrelated, but can you please check on these settings first?

  1. Assist should be set to True to Life / Hard. This is because any flight assistance that’s turned on, will override the autopilot, which will make the aircraft misbehaves. This includes overriding the flaps settings, the autothrust, sometimes the nav, and definitely your approach before landing. These assists should only be used on small GA aircrafts with no or at most simple autopilots. Complex computerised aircraft such as airbus will not benefit from the assistance settings, in fact it will screw up with the complex autopilot.

  2. Flight model should be set to modern. This is because the flight made by asobo have codings that are designed with modern flight model. Using legacy model would conflict the aircraft coding designs and create all sorts of issues.

  3. Set your deadzone to at least 5%. This is because micro inputs from your controls may be registered as valid inputs, which again will override the autopilot controls. Setting the deadzone will have a margin where these micro inputs will not be registered and will prevent it from overriding the autopilot.

  4. Also note that the sensitivity setup is changed in the recent patch, so you might need to re-familiarise yourself with the new setup and set a new sensitivity settings for the new patch.

It’s definitely an issue with the sim itself. I’ve seen you comment in a few threads of this same issue. I’m glad you’re not experiencing it but it is definitely present.

67

I’m just saying that if I’m not experiencing it and someone else does. Then there’s definitely something different from my setting with other people’s settings. The only thing that we all use the same is the sim itself, while I might have a different hardware than other people. So it could be a hardware issue that other people are experiencing. But if it’s a sim issue, then there’s definitely something different between my setting and everyone else’s. I’m just trying to help as many people as I can with this issue by showing them what I have in my settings which hopefully could find the root cause of the issue.

69

Yeah it’s quite peculiar. What are you using as an input, yoke, stick etc? You don’t have any add-ons installed that could affect the physics do you? Also reference this video 23:30

Yeah, I noticed that video a while back while I was learning about the ILS approach, and I do see a few broadcast that shows the wing dip on flare.

I’m using Logitech X-56 HOTAS. I also ordered a pair of Thrustmaster TCA Officer Pack Airbus Edition coming as well. But using the X-56 I set my deadzone on all axis to 10%, and test out my flare technique. Sometimes I have the tendency to flare while not pulling it straight back but by having it slightly pull to the side toward my body (usually left side because I’m using the joystick with my right hand). I don’t want this subconcious movement to register as a valid roll command, so I set it to be within the deadzone so it doesn’t register the slight side movement.

This tendency is even more prominent using an Xbox controller or any other gamepad with analog stick because there’s such a small space to travel to in a 360 degree radian that it’s almost impossible to be absolutely certain that when you pull back the stick for flare, you’re pulling it exactly at 180 degree direction. A slight pull to 179 or 181 degree would register that 1 degree to the side as a valid input, thus rolling the aircraft on flare. At least, that’s my theory.

I only use the A32NX development version, some liveries, and the tiny taxi ribbon mod. That’s it.

This is why when I set up my sensitivity or deadzone. I practice my flare movement, and keep an eye out on all the axis. I see the X axis moving when I’m pulling it on the Y axis, it means I’m not pulling it straight due to that tendency. And set the deadzone accordingly, then practice again. Until I can be sure that my technique doesn’t move the X axis anymore.

I guess you’re the only one who never experienced this, plane with propper flight dynamics should not behave like that, it’s not about landing tehnique or joystick sensitivity. I have flown in p3d, fsx, xplane, and not one a320 with decent flight model was behaving like that on landing.

72

Just gonna budge in here because it seems that after 70 replies there’s still a debate as to what is happening and it’s clearly a bug. Have any of you looked into the cfg files to see if anything can be directly edited to remove any sort of ‘flare mode’ or whatever and just work from there? Clearly Asobo doesn’t have this on their list of priorities so it might be nice to get together as a community and try to dig through it ourselves by figuring out what variable is causing the issue.

73

That may be true. But I can’t speak of whether the flight dynamics is proper or not. I only flew the FS2002, 2004, and FSX. And the last time I fly FSX was 6 years ago or something. While I do feel it’s slightly different than what I remembered, I always tell myself “it is what it is” and make do with what I have.

Besides, if it is a proper flight dynamics issue, there’s really nothing I can do about it. I don’t have enough knowledge to report a bug if it’s not a proper flight dynamics or not because simply “that doesn’t feel right” isn’t enough.

What I can do is that if the flight dynamics is different, then I fly differently. And I keep trying to fly and hone my skills to make it work with what I have in the sim. And yes I’m flying in a certain way now that it just works for me. It’s the only thing I can control, myself. I don’t have control over the sim on how it should be.

74

There’s no different flight dynamics, they’re either right or wrong, it’s more than obvious that msfs has problems with flight models, we should not accept wrong as different and learn how to deal with it, this is a flight sim, flight dynamics are basic stuff.

75

Like I said, I’m not an engineer nor a pilot, so I don’t have the information to tell them it’s wrong. You should do it. Report a bug to zendesk, tell them it’s wrong, and show them what’s the correct flight dynamics.

76

That’s already reported several times, real airbus pilots also gave their opinion about this issue on more than one thread, Asobo is aware of it since launch. Devs from flybywire have knowledge about propper flight model and how to fix it, but Asobo is refusing to communicate with them.

77

Then there’s nothing else we can do but wait, is there? You’ve done all you can, the community has done all we can. So we just need to wait.

78

same here…

I can land pretty smoothly even without using ILS in other sims.
However, in MFS2020 this bug ruins my landing quite often.

79

Press ESC around 500ft, save a .FLT file and upload it.

Then we can load the file and compare different landings.

80

This is a good idea. I could help do the landing on my end and compare it as well.

I’ve noticed the landing roll issue while using my thrustmaster joystick, but when I use the honeycomb yoke there is no roll. Dead zone set to 5 on each. Not sure if someone else has mentioned this yet.
