Ok, I've had enough of the wing drop issue in the 320. Some will say, well you have to maintain the speed all the way through touch down, negative. That would be unrealistic. So, if I remember right, the landing speed for airbus is at 1,23 vStall. That is 23% above stall. Now, if you fly the +5 additive, you gain an extra margin above stall. At any rate, when flying the actual MSFS A320, you should be looking at about a 3.3 pitch on approach +5 speed on a 3 degree glide path. A standard Flare in the scarebus is about 4 degrees of pitch change. Even though you minimize the bank to no more than 15 degrees on final approach, you have up to and a little beyond 30 degrees of bank protection. The jet has a max demonstrated crosswind of 33kts with gusts up to 38kts. In other words, control authority is there. You still would be able to bleed your 5kt additive and touch down no less than Vref - 10. To make it more visual, lets say the VLS is 130. At 1.23 vstall, you are looking at a stall speed of roughly 106kts. Again, I should not be experiencing wing roll off even at -10 VLS. I have experienced those tricky mechanical impacted winds where hangers can create a funnel of fast moving air across the runway. Even then, it's controllable even if I am caught off guard. One has to keep in mind that your control authority is based on single engine, miss trim and flight control malfunctions. That's when aircraft control can be dicey with some cross winds. On a normal jet, control is not an issue.  

Now, I have noticed that the G36 has had some modifications to it in the flight dynamics arena. I am shocked that no one has attempted to modify any of the heavy metal jets. Strangely, the wing roll off seems to only happen in the 320. Has anyone created a decoder ring for the flight dynamics in MSFS? I guess I have to start diving off into this to figure out what setting causes the roll off. It has to do with airspeed and probably proximity to the ground. For a good frame of reference, fly one of the FSL 320 jets. They have actually made a solid representation, even fixed the nose down feature in the flare that makes the feel what it should be.

I posted something similar a few weeks ago.  The A320 is really a mess in its default state. The aircraft won’t fly stable approaches for me since two updates ago and just craters to the ground with anything short of 170 or so knots. 

I use the FlyByWire Mod and do not experience it at all, never have.

> Make sure your peripherals are calibrated (under Windows) and make use of the new sensitivity curves on your axis.

> If nothing else turn off 'FLT CTR' (overhead panel, below the ADIRS) on final, that will turn off the auto trim (you have to work a bit more to keep the aircraft stable), but it will eliminate the wing drop.

I know it is a workaround, but until somebody figures out why some people experience this, it works.

It's something I haven't experienced in the last version of the sim - installing it as I write this message - but it's really "irritating" as the OP mentions, and I believe I was able to experience it at least once with the FlyByWire MOD.

 

I believe it's closely tied to the "Magic" operated internally when an aircraft model is declared "fbw" in the flight dynamics conf file, and I believe the FlyByWire mod doesn't shortcut this ( ? )

 

We will probably have to ait for ASOBO, or whoever did the model of FBW for them fixes the bugs ... or the SDK is made more complete in order for 3pds to be able to code it themselves.

The FBW team are already working on a completely custom Fly By Wire system ./  They have someone on the team who has worked on the Airbus control logic and also has access to the required information

Wow! That's great news !

The most interesting infor I always share with my fellow airbus ( and boeing ) drivers at the glider club ( where they go to fly for real 🙂 ) is that they all fly pretty much the same way, using the very same techniques when flown manually...

I look fwd for that MOD, and I take my hat off, showing my really bald head ( uninstalled hair long ago... ) to that team !

Erich- that is the sort of information that has me up at 0400L :).  This new sim has catalyzed the spirit of community in FS unlike any other release.  That may indeed prove to be its biggest strength. Some of our better freeware scenery developers, @robert young's Turbo Normalized Bonanza, @kaosfere and the entire Working Title Team and FBW with their A320 mod, may well end up finally upsetting the apple cart of commercial development.  Until now, with a couple of exceptions like @mjahn's C-47 supported by Jan Visser et al, and Nigel Richardson's Tutor, mostly you got what you paid for in freeware... times, they are changin'. Our developers are no doubt paying rapt attention, and restructuring their pricing models considerably lower, as we speak. I would not want to be in their shoes at the moment... the total profit potential is much, much larger, but the expected result and work involved has restructured.  Mediocre is no longer acceptable.  The established developers will again rise like cream, but many of the less than stellar purchases I used to make are no longer needed.  Also... the sheer chalk and cheese aspect of former and current marketplaces and revenue therefrom, demands thought to older pricing models.

In six months I will either be proven an word not allowed, or sagacious beyond the Trolly Dolly's capacity to imagine 😉

Another earthbound misfit, I- C

 

PS- hope more than just us old farts got the two sublime verse lines there!

PPS- when she's in earshot, the Trolly Dolly is always referred to as "She Who Must Be Obeyed" lest you lot think I've really gone bananas.

Excellent news, thanks for sharing..... How come these guys can do so much, yet MS/Asobo at times seem to really struggle to sort the Airliners out... A lot of people ( Me included) bought the Sim to fly Airliners, with some GA thrown in at times...

I wonder would it be possible to link in the likes of Simbrief or Navigraph into the A320's system ... or am i talking ****  and it just would not work or be possible.. ( I know you can download and install the Pln at present) But is there the chance of better intagration, and possiblity of updating the stars etc..

They discussed this issue in the last Q&A. I can't recall all the details but I believe they found a coding issue where their FBW software implementation thought the aircraft was close to stalling and was limiting elevator authority as a result. I can't remember if this was supposed to be update #5 or update #6.

Yep i forgot about that. In the last development update video they stated that they are working on the FBW logic for the 787 and A320. I think they have information in regards to how the AC should handle and are working to make fix the lack of authority in those landing phases. Its the very last development update video. Check it out if you have the time.

As some of you have stated, it's the fly by  wire system. Disabled it and my landings are like my G550 landings IRL lol. See if this trick works on the 787

Wait, it's locked 😆

Please go and upvote this topic on the official forums: https://forums.flightsimulator.com/t/a320-rolls-left-on-retard-and-flare/190230/172

I got the mods to merge the tens of topics complaining about the same thing into one a couple of weeks ago. The upvotes could not be merged however, which was the main thing I hoped would be achieved. Nonetheless, the more people who upvote this, the more likely it is to make it into the top bugs list, which seems to be the main thing the devs look at when choosing what to address next.

It doesn't help that 1g stall speeds are wrong in the Asobo flight model. Have a revised flight model in draft form in this PR at flybywiresim (https://github.com/flybywiresim/a32nx/pull/1580), but am still looking at pitch angles in different configurations before it will be ready for QA testing there.
