New AIRAC crashing MSFS20 w/ FSHud

USA5775 · March 20, 2026, 1:34pm

Ever since March 18/19th and updating Navigraph AIRAC data, MSFS 2020 crashes when FSHud is opened. This crash has been replicated multiple times. Only started when I updated the AIRAC.

So the title of the thread should be “crashing sim”, correct?

USA5775 · March 20, 2026, 1:47pm

Yup, I just updated it

There’s also been quite a few FSLTL users reporting the same, and that it’s resolved by removing the Navigraph folders. It’s happened before, so maybe it’s a similar issue? CTDs at VHHH with FSLTL

Hi,
not reproduceable here. I have installed FSHud and can use it without crashing (but I don´t use FSLTL). We will check it later. Thank you!

Cheers,
Richard

Thank you! I use AIG but have FSHud inject the flight plans.

Moonglum · March 20, 2026, 3:14pm

specifically 2020 though - are you trying it on 2020?

NAVData · March 20, 2026, 3:19pm

Yes, FSHud with MSFS2020 - no CTD, but no FSLTL or similar installed …

Cheers,
Richard

Hi.

I got CTD in all airports upon traffic injection from FSHud. When I remove AIRAC from navigraph, it works well. There is no software updates from FSHud for quite some time, so definately not FSHud issue. There hasn’t be any issues before 2603 so is definately AIRAC issues.

Thanks.

Hi,
I don´t know which SIM you use, but I tested it with MSFS2020, and there was no CTD. So, not reproducible on my end, sorry.

By the way, please avoid double-postings in the future. There is some equal report here. It makes our lives a little bit easier.

Thank you very much,
Richard

Hi,

When you say remove the AIRAC from navigraph you mean remove it from the navigraph hub? Just confirming because I’m going to try a similar approach and test

Hi! Permanent CTD (sometimes immediately, sometimes after one hour of flight or so) after installing AIRAC 2603. I am not using FSHUD or similar. Please fix this … as many users (almost all in my forum) encounter this.

HPST1964 · March 20, 2026, 8:47pm

I‘ve the same problems.

I also run FSHUD and FSLTL but I think it is a Problem of the core of MSFS2020.

Small Update:

The Problem is not the MSFS itself! The AIRAC from Navigraph seems to be responsible.

As a workaround, deactivate AIRAC in NG Hub!

MSFS2020, FSHUD, FSLTL, NG Chart and LittleNavMap are than working.

In my opinion, the issue doesn’t lie with Asobo. If its so, the previous AIRAC will reproduce the same issues.

For such situation it is already obvious enough that is the issue with 2603, but is weird that everyone but only the admin don’t reproduce the issues. But I really hope that they will acknowledge it. I believe no one will enjoy MSFS without AIRAC and traffic addons.

HPST1964 · March 21, 2026, 7:11am

Hello,

thank you for your reply.

You are very right! I do yesterday the first flight without CTD since AIRAC 2603 was published.

I have improved my entry!

FSFSIkarus · March 21, 2026, 9:16am

Here the same. De-installing in the Hub is helping

Starfield · March 21, 2026, 10:28am

Usually Navigraph and AIRACS work totally fine! This issue is a very rare one.

Ian · March 21, 2026, 10:50am

We are investigating the CTD’s to determine the cause. Thank you for your patience and understanding.

Cheers

Sorry guys, but I still can´t reproduce it - believe it or not … I have now spent nearly 12 hours, with a few hours break for sleeping, to identify any issue, but I can´t.

I run MSFS2020 (AIRAC 2603 installed) and FSHud 2.1.40 (also 2603 installed) - here at LOWW:

No CTD. Possibly I’m doing something wrong or not in the same step as you. So please, can someone give me an exact test case I can run on my system here to reproduce these CTDs? Means step-by-step instructions that I can follow to get the CTDs?

What have you installed, what I possibly don´t have… or is it only when you start FSHud from the menu bar in MSFS2020?

Thank you very much,
Richard

Same problem here. So far 2 flights both ended in CTD. Both flights were after installing the new AIRAC.
My system is flawless: scannow and DISM commands found no errors. No new software installed, just the new version of AIRAC.

FSHud not installed, FSLTL installed. The aircraft is PMDG777-200ER
