Fuel Controller Failure Zeroes Fuel
-
While testing the binding I created for the emergency power lever, to see the response to the lever I manually failed the fuel control unit. This removed all the fuel from both tanks except for the unusable 2 gallons in each.
This happens almost immediately and will still happen even with the engine off. Having a fuel controller failure and the condition lever in anything other than cutoff will empty any connected fuel tank. Tanks set to Off are unaffected, which doesn't help resolve the situation but may point to a cause.

Unfortunately, I am unable to reproduce this. I said to myself, "what?!" when I read your report, since I'm really not sure how that would be possible. If you really think you're seeing this, you can test whether it has anything to do with my code by removing a section of my XML (since I know you are well acquainted with modifying my aircraft). Look for the block of code commented
Fuel Crossfeed Logic, and just remove it to test. That's the only place where the fuel level of the aircraft is modified after loading.EDIT: Oh, I assume you were triggering the failure using the HTML events. I was able to reproduce that. Unfortunately..... that is functionally identical in my code as triggering the event via the tablet, so it seems we have an Asobo anomaly on our hands, at least to the best of my estimation. I was able to reproduce this only once at the beginning of the session.

Interesting, it was happening repeatedly to me, and after several startup and shutdown cycles since I had done a few flights without going back to the menu.
Notes I should have included in my first post: using the Cargomaster, MSFS 2024 SU4 release, and yes the tablet to manually trigger the failure. I had thought it would be in an area using common code across variants, but I did not actually test that.
Is there anything I can do to help troubleshoot it? The first time I triggered the failure was actually the longest it took to happen; I had a few seconds to play with the throttle and see there was no engine response, and right around when I moved the emergency lever was when it died. I had thought I had done something wrong until I noticed both fuel tanks were at zero.
Subsequent failures of the FCU produced quicker, but not quite immediate results. Sometimes it would instantly zero, on at least one occasion I saw the tanks empty in a few discrete steps.
