They are aware of it as an issue. Sadly no XBox workaround. Hopefully a hotfix is forthcoming. From twitter.
I hope the following can provide the developers with some useful info.
Yesterday I tried to complete a long flight. I chose a long route deliberately to see whether the sim crashes to the dashboard. Sadly, it did, but it might provide some insight.
The route: Amsterdam (Schipol) to Menara (Marrakesh). IFR flight (High-altitude airways). Flight time approx. 3.5 hours.
Settings: Live time of day, Live Weather, Live AI traffic, multiplayer OFF. Bing data streaming on, rolling cache settings all default (I haven’t cleared it prior to this flight and it is set to 8 GB).
Here’s how it went:
Boeing 787 Dreamliner: CTD after ~35 minutes after take-off.
Boeing 747-8i: CTD after ~45-50 minutes after take-off.
Airbus A320neo: No CTD. The flight could be completed without issues.
At first I thought the CTD was caused by the location (somewhere over France), because the two crashes occured quite closely in time. However, the Airbus flight had no problems whatsoever. I have a feeling that the larger planes have something that’s “too much” for the Xbox consoles. Maybe their size, the graphics, or the heavier simulation, the glass cockpits or something. I do feel that the performance is worse in the 747 and the 787. Framerate stutters more, even high in the air, and it seems to lock up just a split second before crashing. It’s not my job to guess but for me it feels like these planes can somehow overload the system (the CPU, the GPU or the memory) and the game can’t properly handle it, hence the random crashes. Or it could be that the large planes combined with the data streaming is too much. Again, not my position to guess.
I hope this provides some useful info. The Airbus definitely feels “easier” on the sim. I don’t have much time to conduct further testing, but when I play I will continue to use the A320neo to see whether it has any issues in the future.
I honestly and seriously hope for a proper fix for this in Sim Update 6. 
Flying the larger planes is an important part of the experience.
This is interesting info, thank you. I’ve not done much flying in the 787 or 747 from the premium deluxe content although I do have both of them. When you see framerate dips did you try quickly switching to external view to see if the framerate recovered at all even temporarily? Just about every time I’ve seen framerate dips it’s always been in the cockpit, and it is nearly always relieved by toggling to external view and back (for a short while at least). Framerate dips flying low in very dense cities is a different case entirely, but that’s not what we are reporting, which is cockpit related framerate dips. I’ve seen this happen with mouse/XBox controller UI conflicts (again inside of cockpit), where the frame rate dives (to the point of being unusable & occasionally with a CTD) but if you hit external camera view, the frame rate all rectifies until you go back into cockpit view again. There is definitely an issue there but a hard one to quantify. I’m wondering if it is perhaps the same issue and maybe its worse in some of the premium planes. I spend most of my airliner time in the Neo which hasn’t been too bad, it has to be said. But I currently don’t fly long journeys.
The framerate drops in external view as well, even more so with the big planes. In fact, I felt that it might even cause some of the crashes, the stuttering feels as if the console is struggling to keep up. Maybe that causes the crashes, I don’t know. There have been a few rough spots with the Airbus as well, they made me worry it might crash but it didn’t.
I have to add that I’ve completed several flights with the Boeings, even some long ones (1.5-2 hours), so they sometimes work. It’s just too random to enjoy.
ok that’s interesting to know too. The mouse/XBox controller UI slowdowns are temporarily relieved by switching to the external view. So maybe it’s a different mechanism, but much as you descibe it does feel like the console is struggling to keep up in the cockpit with graphical output rates and it can lead to CTD’s. I have had it happen on multiple aircraft & I now just leave the XBox controller powered down and use a Hotas+KB+mouse whch doesn’t cause the issue. Neither does the XBox controller on its own, but you can’t seriously fly with the controller alone esp. on airliners.
After the update I did a couple of 2 hour trips in the A320 with no issues. They even fixed the ATC bug. I decided to push my luck with a 7 hour flight in the 787. Lasted around 6 hours before CTD. No warning, stuttering- nothing. Series X, mouse/KB/HOTAS, controller off AI traffic off, custom weather and time.
Too bad & sad to hear. From one perspective I can see why devs may find it hard to do the work replicating 6-7hr flights, but I do think they should be installing some kind of background crash monitors for these type of issues that reports back on system resource utilisation etc and files a crash report. I’m more a short flight type person & get plenty of enjoyment out of <2hr flights but I feel your pain with this issue (and the black display screens one too).
It’s useful to know that CTD happens even with traffic and live weather off. That means they’re not the culprit. Although I don’t know whether the developers read these feedback at all. And since they surely don’t have time to fly for hours looking to reproduce this random issue, I’m not sure how they’ll manage to fix it. But I hope they will.
I just found this thread of PC users from April discussing resource issues FPS drops and CTD’s on long flights >1 1/2 hrs. Many experiences seem to mirror what users are experiencing on XBox with long flights. Keep in mind XBox has less resources on hand than some of these PC simmers did in April.
Perhaps the resource issues are the same though. Things like this sound all too familiar-
“Same thing happens to me also on flights over 1 1/2 to two hours. Especially landing at the larger cities. Some kind of bug, memory leak, or something.”
“I have experience the same. Some kind of memory performance leak in flight that are longer than 90 minutes.”
It has just done it again when I was just starting my descent from FL390 was so annoyed ! Rome to Dubai and the flight hours aren’t in the log book, hopefully I still get the 100 hour achievement soon even though it says 93 hours.
A memory leak sounds right as it appears to happen when I’ve simmed up to the top of descent and then when loading in the city etc boom black screen back to Xbox dashboard. It’s like the Xbox is struggling to keep up 
The PC folk in that thread were speculating about a buffer/log file filling up with just background rubbish eg ATC or live traffic. They thought they were onto something as for some deactivating Live Traffic, then activating it again made FPS recover. Didn’t work for all of them though. They also report that as soon as wheels touch the ground in a slooow frame rate landing (they can see rates down to 5fps) the framerate recovers. Some quite significan’t hardware in PC land was being slowed down from 60fps to unusable, and always on long fligths at or near approach. Many reported their GPU to be at low levels of utilisation when the framerate dip happened.
That’s why it would be good to know if XBox ‘long flighters’ see frame rate dips/issues at any time prior to CTD. Maybe the XBox hits same software issue they see, but just crashes to dashboard instead when frame rate drop enough or logfiles/buffers fill up.
I had Live Traffic on tonight. I can’t pinpoint it to that but maybe with the amount of traffic the big cities have, it is struggling on the sim?
I don’t know though as I think some people above reported CTDs without it on. All I know is without live traffic and AI on the sim is dead.
To be honest I like long flights so its annoying. I also like the approaches in big cities. Might be time to spend some £££ on a PC 
You could try like they suggest to toggle live traffic off at some point during the flight to clear a log file, go back into sim, then toggle live traffic back on again maybe refreshing that log file. Over different areas world wide data like that could just mount up a bit over time. It may be worth a try at least. I don’t do long flights or I’d have tried it already.
PC users are seeing issues though, so no guarantees about addressing this issue by buying one!
Yeah I’ll try that. I’ve turned off all form of traffic for the time being just so I can make some progress towards this achievement.
I was joking as I’ve not touched PC gaming for years. I did have FSX years ago so I’ve recently got back into flight sim now. I like how PMDG and other developers are still going. Fingers crossed they bring some aircraft over.
The sim looks great on here it’s just a shame about the CTDs. Like you said though these issues are also with PC users. They’ve fixed the ATC altitude thing at least 
I feel you cockpit screens out and Sim crasheding hopefully they fixed it soon for Xbox series s and x
They also seem to have fixed the bug on the Neo where ILS frquencies we’re propagating through the MCDU - you had to enter them manually sometimes, which was a real pain. It appears fixed now. So some bugs are getting addressed albeit eventually. CTD’s probably harder to debug, but a small lightweight monitoring/reporting app may be a good idea. Our reports are of the vague and not easily reproducable variety. Error codes and hardware/memory/resource status report are likely what is needed, we don’t see those on XBox.
Natably I haven’t had a CTD for 13 cumulative hrs over 3 days of flying now so everything is back to being stable. Which makes me wonder after seeing 3 CTD’s in 24hrs after initial install of WU6. Maybe the servers are the issue. Just added live traffic back in last night and did a first 40min flight with it on again. No issues.
I do see some framerate drops around airports which can be very annoying on landing. I also have flown mainly clear skies recently will try running with cloudy conditions again.
I’ve had more CTD on XsX since the recent update. Just happened two games in a row. Rarely happened before update.
Feeling like they don’t wanted fixed Xbox series x and s version cockpit screens from going out and Sim crasheding
