Another misalignment example is LJLJ airport. It was intorduced with SU5. It is very simple to reproduce: just sit into any airplane and fly ILS approach. There is only one solution to this, we need to kindly ask Asobo for a remedy.
Is this the amount of offset you are seeing? Looks like maybe a degree or two? I started on the runway and tuned to the 28L localizer. If this is the amount of offset, I personally probably would not have noticed it during landing.
This one appears to be more egregious. You can also see the offset if you look at the ILS feathers in Little NavMap

If you identify others misalignment, search in the main thread (MSFS 2024 Airport / Helipad Issue Tracker) if they have not already been reported there. If not add a new entry following OP instructions in their 1st post.
Just looking at Little NavMap, this one looks similarly offset as the EGCC example.
This topic isnāt marked as Feedback Logged or Bug Logged. Does anyone know if Asobo is tracking this feedback, or does every airport need to have its own bug report?
EDIT: Never mind, Demented answered my question while I was typing!
This has been going on for over a year. Sounds like we need a replacement tech team since they canāt figure it out.
This is getting interesting. What (data) have Little Navmap and MSFS in common?
Little Nav Map builds its scenery and nav database by reading out all of the data from the simulator, so in theory LNM is an exact replica of the sim data that is installed.
I think the procedure is a bit different if you use Navigraph data, but I donāt use that anymore in 2024.
Once LNM has built its database, you donāt need to open the sim and load into airports to check ILS alignment. You can just look at the green ILS feathers on LNM and get your answer.
Is there anything revealed by the metadata if you click on the ILS feather (or maybe you have to click on the localizer antenna) in LNM? LJLJ is 5Ā°E mag var and it doesnāt look like a 5Ā° offset from runway heading, so itās probably not that. But I wonder if thereās a rounding issue with the magnetic heading of the localizer or something.
You probably understand the underlying metadata better than I, but from what I gather, I donāt see any obvious issue? Is a fraction of a degree in the magnetic offset significant enough to cause the lateral offset for this particular runway? Maybe the MSFS airport runway is very slightly misaligned or rotated? Hard for me to tell what the actual ground truth is.
There isnāt quite enough data visible there to conclude anything, but yes, on a 10,827ā runway, in which the localizer is another 1000ā+ past the departure end of the runway (DER), a 0.1Ā° angular offset will translate into a roughly 21ā lateral offset at the approach end of the runway (AER). I used 12,000ā as the distance from the AER to the antenna array. So for every 0.1Ā° at that distance, add another 21ā or add the same for every 12000ā of distance from the antenna array, and the math continues to scale linearly.
So with, letās say, 0.2Ā° offset at about 1nm from the end a long runway like this, youād be 63ā off centerline.
Looking at this further, the LOC is nearly meeting the runway edge at the AER. With a runway width of 150ā, that means it is resulting in a roughly 75ā lateral offset. That would mean itās an angular error of 0.36Ā° or thereabouts.
Maybe itās more impressive that there arenāt more misaligned paths given how much accuracy is needed throughout the whole process.
This is really starting to annoy me, .. EGLL 27L and R are out of alignment as well, im using the handcrafted EGLL and PS5 so im unable to use the Navigraph data. Hereās a screenshot of 27L short final .. you can clearly see im established on the LOC but itās bringing me in far too right of track ā¦ how can we perform any kind of low vis approach like this??? ā¦ this should be a top-priority bug ā¦ some kind of ILS autoalign program needs to be done or something like that , Using Xplane Toliss airbuses have an ILS autoalign feature that works well in cases like thisā¦ pleaseee can you fix this it really takes the enjoyment out of landings
Well I started this topic over a year ago and I can verify my original airport reported (YMML Melbourne, Australia) still performs ILS approaches like this for the 16 runway. Interesting the 27 runway ILS has never been an issue. It lines up perfectly.
I hope they can fix it soon too.

Itās a shame isnāt it ā¦they are all for releasing world and City updates but nothing gets done about the underlying issues like this ..the challenge of landing in low vis CAT2/3 conditions is fun but its not when you land well off center ā¦it was fine when the ILSs were linked to the Airports AFCAD files in FS2002 FS2004 but now they are connected to Nav Data files with donāt always line up with the sims scenery so end up with issues like this ā¦some kind of auto align feature needs to be done
I remember reporting a bug about EGLL ILS it was replicated and reported but surprised its not fixed yet this was pre su5 too
