Aircraft crashed whilst on "pause at TOD" mode on long flight

[Ed Moore]

Hi guys,

I was bringing my plane back across the Atlantic, left it about 0130 to go to bed, all seemed fine. Pause at TOD mode was definitely enabled and armed.

This morning I have an unpaused sim sitting in a cold and dark aircraft back at CYUL

Log included, it looks like it crashed at 2022-01-09 02:34:09.

Any pointers appreciated! Are there any other log files I should upload? Fortunately I saved a state file just before I slept so I can carry on from there!

 

I've included the state file just as I went to bed, it crashed an hour after that. Being able to restore the state this morning has made me SO HAPPY!

Update: this seems to be a “hit the sea” crash rather than an software crash, just taking a look at the FDR I was pointed at to figure out what happened. Seemed like it had plenty of fuel.

ActiveSky was running so maybe it dumped a weather update that took out the AP

OK another update - the FDR shows the AP disconnected which caused the crash, but no idea what caused the AP to disconnect!

Hi Ed,

I'd say you're right about ASXP dumping in a sudden weather change. If the aircraft is put under enough load the autopilot will disconnect.

Hi

I observed same issue. In the CL650 Log i could locate, the Disconnection occurred when GFS Weather download a changed TP Altitude...
