Random CTD after hour long flight. Possible ATC interaction?

:wave: Thank you using the Bug section, using templates provided will greatly help the team reproducing the issue and ease the process of fixing it.

Are you using Developer Mode or made changes in it?


Brief description of the issue:

Random CTD while communicating with ATC after an hour long flight. I took off from KMTH, in the Grumman Goose, and flew NE, then North along the Florida coast. I was using flight following, and been repeatedly switching from centre to centre. When I got to close to Boca Raton, I cancelled flight following, and contacted tower to request landing. A few seconds later the sim crashed. FSRealistic was left running in the background playing continuous audio. Crash details below:

Faulting application name: FlightSimulator.exe, version:, time stamp: 0x00000000
Faulting module name: FlightSimulator.exe, version:, time stamp: 0x00000000
Exception code: 0xc0000005

Fault bucket 1197067976364463698, type 5

Detailed steps to reproduce the issue encountered:

Difficult to reproduce. I suspect if I were to fly that route again, and do the exact same thing it would probably work.

PC specs and/or peripheral set up if relevant:

Intel 11900K, Nvidia 3090 FE, Gigabyte Z590 Aorus Ultra, 32GB RAM, Samsung 1TB 970 Pro

Do you have the same issue if you follow the OP’s steps to reproduce it?

Provide extra information to complete the original description of the issue:

If relevant, provide additional screenshots/video:

Most likely sound driver related and/or corrupt FSRealistic install.

Check FSrealistic for support 1st.

Uninstall FSRealistic and see if it still happens.
Update/reinstall sound drivers and test functioning in Windows.
Set your preference sound in msfs.
Install FSrealistic.

All good advice, but I don’t have any issues with any other titles, just this one.

And its not like I can replicate the flight, as the expectation there is that this is reproducible, which it isn’t. It appears entirely random. I would agree however that it may be audio related, but I was getting these ATC crashes, rarely, before FSRealistic even came out. So my suspicion is that it is the ATC audio that is doing this, and not FSRealstic.

My second flight of over 2 hours had FSRealstic loaded, but I didn’t use ATC at all. And on the flight that did crash I was using ATC the whole way, for flight following, with repeated swaps between frequencies, perhaps more than 10 times. It was only when I contacted tower Boca Raton that it crashed.

I think the audio loop was only causes by the sim being dropped out from under FSRealistic, and it never received a signal to stop playing one of the audio files, as the sim had crashed. It might do the same thing if I were to ALT+F4 the sim mid-flight, which also might be worth testing.

Even then I might only get one crash per month, it really is that rare. One thing worth testing though would be to disable the audible ATC, and use text only. I’ve seen some users have that configured on videos. But I might have to test it like that for weeks or months.

This isn’t the kind of issue where I can have a single flight, and declare the issue resolved. MSFS has never been like that for me, sadly.

That said it was a fun flight so I may refly it anyway. :slight_smile:

Hopefully others can reproduce this so we’ll know if it’s a core sim issue or use of addons. :+1:

Given the error message, the 0xc0000005 one, I don’t believe I have ever had a single other game, or program fail with that error code.

I was receiving those probably as far back as 2020 if I remember right, before FSRealistic even existed.

My thoughts on this are that MSFS is still at times trying to access memory it shouldn’t, and causing these exceptions. I suspect there are many triggers for this.

To be honest, and I’m sure others feel the same way, I would be happier if it were one of those issues where you would get it 100% of the time, repeatable, but sadly this error doesn’t seem to work like that.

In previous cases where ATC seemed like it was related, I actually heard the ATC speech stutter just as it crashed. That didn’t happen here, it just went quiet then died. :slight_smile:

Regarding audio drivers, they are up to date as I installed the Logitech G560 drivers last week I believe. And I was having that crash rarely before I even bought those speakers, and was using a little Jabra 510 desktop conferencing set up to give me some audio.


I don’t have the crash logs to provide any useful data to the discussion but I had a CTD last night that has some similarities. I decided to take the C414 on a cross country journey. I was about 45 minutes into an hour long leg when the CTD happened. Prior to that, I had been running ATC but just decided to turn it off. I was also using FS Realistic. Anyway, a few minutes after I had turned off ATC ( I had also been fiddling with engine sound levels in the sim to try to get the ATC sounds clearer) the trip abruptly ended.
Again, I realize that this isn’t much help other than acknowledging that some CTD’s hit harder than others. I lost all interest in continuing on at that point!

I flew for perhaps 8 hours over the weekend, on a number of different flights. In all cases I used ATC, but this time I had the ATC voices turned off entirely, so it was only text based in the ATC menu.

No crashes. It’s still far too early to suggest this is proof, but I plan to continue like this for the next month or so.

Which reminds me. Does anyone know how to enable the ATC alerts to appear at the bottom of the screen, as I have seen in some videos. I assumed that was going to be the Subtitles function, which I have enabled, but that doesn’t appear to do anything at all.
