MSFS Navdata issue with FBW

Navigation Data General MSFS Data
1

Installing or updating the A32NX deletes navdata for me. Have to reinstall.

Hi…,

Please:

  • shut down sim
  • backup content.xml file likely at
    %localAppData%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache or %appData%\Microsoft Flight Simulator
  • delete content.xml
  • start sim and then shut down again
  • reinstall navdata using latest Navigraph Navdata Center 1.0.3 (or later).
  • Please check data. If an issue please upload content.xml

Cheers
Ian

It’s enough if I just reinstall navdata and then relaunch MSFS. But I have to do this every single time after an update or install of A32NX. This never happened before. I don’t know where the problem is — whether it’s with the navdata, MSFS or A32NX, but all parties have been notified so hopefully you can come up with a solution. :slightly_smiling_face:

Please upload your content.xml file … no addon (scenery nor aircraft) deletes any navdata package. Aircraft use the data only but don’tadd any information in this content.xml file. So, it´s impossible, that the FBW deletes a package.

You must have an other glitch on your system and to find this out, we need more information:

  1. Do you use the latest Navigraph Navdata Center (at least v1.0.3)
  2. Do you use AddonLinker or similar ?
  3. Do you have 3rd party sceneries installed?
  4. Do you start the Navigraph Navdata Center before you start your sim ? Please doas this is an important step. We are working on it to start this app automatically, so that you can´t forget it.
  5. As I have requested before, please upload your content.xml file here

Thank you very much. With your help, we shall find a solution, we have found it on every issue till now …

Cheers,
Richard

I know of at least 6 other people in our discord who have the exact same problem. Maybe it’s not the A32NX but I know this:

I can launch MSFS 100 times and everything will be fine. When I update A32NX to a newer version and launch MSFS, the Navigraph navdata is gone. I have not found any other situation where it would disappear, including installing new airports or installing new aircraft, e.g. Aerosoft CRJ, PMDG DC-6, etc.

Re 1: Yes.
Re 2: No.
Re 3: Yes.
Re 4: No. I only run it when I need to update the AIRAC. The need to have this app running constantly in the background is a bad idea.
Re 5: Attached.

Why?

You can also start the Navigraph Navdata Center and close it immediately BEFORE you start the sim. When this is more comfortable for you, this is also ok … the important part is only, that this step should be done before you start the sim - every time. Only with this start-stop (or background) you can be sure that all packages are in the correct order … this scenery file is very tricky and you have no possibility to prioritize the packages, therefore this is the only solution to place the packages on the correct order - thru an app.

What version of FBW do you use? Stable - Dev - Experimental? I will try to reproduce …

Thank you
Richard

Everybody wants to run in the background. Volanta, Logitech, Razer, Simbrief Downloader, AAO, Simlink, etc. … if I let every app that wants to run in the background, run in the background, I’d have over 20 apps in my taskbar just wasting resources. :smiley:

Since when is it required to launch Navigraph Navdata Center before running MSFS? I have never done this since MSFS came out and this is the first time I have issues. Could you please explain what launching Navdata Center (or post a link to an explanation) does exactly, if I don’t press the “remove” and “install” buttons? It edits the Content.xml file before every launch? How exactly?

I have been using stable 0.7.3 for the past few weeks since DEV was causing CTDs but switched to DEV yesterday, because of an issue with a CTD caused by navdata (separate thread here, entering 04L for arrival at EFHK causes instant CTD for stable A32NX).

Hi,
most of the apps don´t need to run permanent in the background, same for the Navigraph Navdata Center, but it helps a lot to not forget to start the apps before you do something. Nearly every app can be closed but must be started to a specific moment and that´s what make such small apps (approx. 100-200 Mb in memory) very helpful for the end-user - he can´t forget to start it … and that´s the reason to run also the Navigraph Navdata Center in the background, and of course all your other apps too.

So, why is this now important:
As we have described in our newsletter and here in our blog, the navdata update contains now two packages (instead of one in the past) and both packages will be placed on a specific position in the user content.xml file. That means, in that moment, when the content.xml file will be changed (ie. you install a new scenery), the Navigraph Navdata Center re-orders your content.xml file immediately, to be sure that the priority of each package/line is correct. That is only possible when you have run the Navigraph Navdata Center …

So, you have two possibilities:

  1. run it in the background, that you can´t forget this
  2. start the Navigraph Navdata Center, start the sim and after the sim is started, close the Navigraph Navdata Center
    or there is a 3rd option also:
    Start the sim → close the sim → start the Navigraph Navdata Center → close the Navigraph Navdata Center → start the sim again

You see, you don´t really need to run the Navigraph Navdata Center permanently in the background, but for me it´s more useful when it does and it helps not to forget something todo in the correct order.

Last to the EFHK issue, which is solved:
As you have figured out - it works with the dev-version but crashed with the stable version. So, it can´t be a navdata issue because when, it should crashed with all versions and also not only with FBW because the files will be used by all other in-game aircrafts too.

Hope that helps,
Richard
