I have a big problem since I am flying on X-Plane11. X-Plane11 always crashs during descend. I already had install X-Plane but there are no changes.

Here is a link to my LOG.txt.

Thank you very much for your help.

Best regards

Hi Freddy

I'm not with Laminar Research, just a fellow simmer in the UK, but when I looked through your Log.txt file I found the following entry just before your copy of X-Plane 11 crashed:-

1:12:02.787 E/SYS: | rel_assert Error! Possibly an out of range vector! Attach the debugger and see who called this!

As you will see from the yellow heighted section, it would be best to send a bug report as suggested to

Personally I would also check your PC/Laptop/Mobile hardware specification against that recommended by LR. More details on this can be found @

Hope this helps :-)
