• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 Problem with ILS "The localizer is not correct"

Messages

I modified DAUA Airport default.
https://flightsim.to/file/96649/airport-adrar-daua
I am now facing a problem with ILS runway 04.
I’ve set custom values in the scenery editor for runway 04 yet they seem to have no effect, the plane prioritizes default values, not the ones I’ve set in my scenery package.
The ILS localizer is not correct. The plane is coming down too far to the right.

Hello.
The Magnetic Variation (magvar) might be the culprit and/or the ILS heading. In your XML the magvar is 2° East and it's 0.8 East presently. Regarding the ILS heading, It's set to 41.00 but the runway heading is 39/219. Perhaps you could set it to 39.00 and see what happens.

I remember having this problem a very long time ago with an airport I worked on...
Best regards.
 
From what I can see it's possible you are missing one statement - the ILsReference and I seem to remember that the frequency has to be a set number of decimal points. Here's my line from YMLT that fixes the ILS that was (and maybe) still screwed. WHere you have positioned it is OK

<Ils lat="-41.54607444221995" lon="147.21186608885458" alt="166.54003489855677" end="PRIMARY" range="50016.79303200000140" ident="ILT" magvar="345.500000" heading="313.00000000000000" frequency="109.50000000000000" width="5.000000" name="ILS RW32L" backCourse="TRUE">

</Ils>
<IlsReference end="SECONDARY" ident="ILT"/>
 
I deleted the ILS text from the file and added deleteAllILSs="TRUE" to deleteAllILSs="FALSE" according to what is stated on forum.navigraph.com.

    </Airport>
</FSData>

Deleted the navigraph-navdata-base and navigraph-navdata folders from Community.

Aircraft that do not use Navigraph Like Airbus A310-300; inibuilds A300-600; Cessna 152. do not encounter this problem.
It seems that the problem is related to Navigraph-Navdata Like PMDG Fenix Airbus A320
