Navigraph data causing 787-10 freeze at SKLC

I have completed about 300 flights and never seen anything like this… I was careful to remove all causes of interference other than the 2 navigraph folders in the Community folder.

Its only happening at SKCC, using the 787-10 at with a route to MPTO, a freeze happens reliably when switching to external view at SKCC after programming the FMC and proceding with the usual start up steps.

here is the route:

to be clear: the freeze ONLY occurs when the 2 navigraph folders are present, and they were freshly deleted and reinstalled and the problem still occurs

sorry, not reproduce able on my system. I can use the 787 in SKLC without any problems. With and without our package loaded. No freeze - with or without the flightplan.

Does this happen only with the 787 or have you tried other aircrafts too

Here - the default 787, current MSFS v1.34.16.0 and AIRAC 2311 installed:

No freeze, no CTD, nothing … load/unload … can´t reproduce it, sorry.

I appreciate your help with this.

I have not tried starting from the runway with the systems started up.

The freeze occurs when starting from cold in one of the parking positions.

After programming the route and turning the engine starts on, the freeze happens when switching to the exterior view.

Sorry, still not reproduce-able.

Cold & dark cockpit - at medium gate - enter the route in the FMC and followed the start-up procedure till the engines are running - goto external view, no freeze, no CTD … switch back and again back to external view. No freeze, sorry …

Same as before - the default 787, current MSFS v1.34.16.0 and AIRAC 2311 rev. 3 installed:


Ok thanks I appreciate your help. As mentioned its a very unusual problem but I can reproduce it still so I will simply avoid this airport and report the issue to MSFS.

The question is:
Does this happened with any other stock aircraft too? Have you tried it because as you wrote, it is a very unusual issue and I’m honest (even it looks so), I can’t believe that this is really an navdata issue. Possible a combination with ither things.

I will analyze the SKLC airport record to see possible more details.

Cheers & thank you

PS: this airport is not certified for a 787 :sweat_smile:

thanks, I will let you know if it happens again. First time in over 300 flights so could even be a single-bit data corruption of something on my M.2 drive (hurry up zfs on boot!). Is there a tool that will check the integrity of all MSFS files?

PS> Navigraph shows the runway as being 6400ft x 148ft wide but in MSFS its severely out of date and only 60ft wide! From google earth the runway appears to have been rebuilt between 2017 and 2021.
