Thank you for the video, Yoshi.

I see two peaks; the first one is lower than Mount Everest, unfortunately. So, a plain cut wouldn't be reliable.

What about the location? Is the crash really time dependent or is it position dependent? Can you return to that place and reproduce the crash?

E.g. does it occur at a rounded number of a latitude or longitude, like E010° 00' 00" or something like that?

By the way, the tab titles of the Malfunction pages are colored when a related malfunction is armed or activated. When all titles are black, there are no malfunctions; so you need not check the pages themselves. (Also please note that some malfunctions may only appear on the pages when the sim is unpaused.)

It indeed seems to happen at round latitude/longitude values.
My test scenario for the past hour:
Takeoff from RJSK, climb to F100, heading 270 to cross E140°. Nothing happened.
Then I remembered the crashes happened at higher flightlevels, so I climbed to F400 and used heading mode to cross back and forth over E140° and N40°. I had the instructor open on the profile page, you could spot jumping terrain at exactly E140° and N40°.
Would be perfect if someone could confirm.
My wild guess:
It happens above the threshold to tropopause at ~F370, have to do do more tests to verify.

I should have read the manual a bit more before impatiently jumping into the cockpit I guess ;D

Update:
I just did a test flight around N30° W90° (New Orleans). At F310 you could tell the full degrees on both longitude and latitude were visible on the profile (terrain trying to jump at you). I also started a flight from KRNO to KFHU which crashed at exactly N38° (W118 1.2°) at F410.

I'm wondering why the X-Plane elevation output at the lat/lon grid borders increases instead of decreasing to zero or less.

Perhaps there is a global "subtraction" system starting at a super high altitude, and this subtraction varies with the latitude to form an oval shape of the planet, i.e. the subtraction might be zero at the equator and very large at the poles?

If that is true, maybe this subtraction system is a new feature on top of the old planet model, and if so, it might run in a separate, non-synchroneous thread which may provide synched results within the X-Plane world, but not in its output stream for external applications.

(I'm just speculating.)
