Keep losing both engines and all power. Help
« on: November 06, 2018, 03:12:27 PM »
I have had issues with my last 2 flights in that at random times the aircraft loses all power and both engines cutout. The aircraft goes simply on to battery power. I don’t have failures setup in prosim.

I can get the engines restarted by starting the APU and go onto its buses. Then putting the throttle fuel levers to cutoff, switching overhead to FLT and allowing windmill start by getting N2 rotation then reintroducing the fuel.

This happened this evening and once the other day when I flew.

At the different times it happened I haven’t being doing anything in particular. One time I was tuning a heading on the MCP. The other time was working in the CDU and the final time was 400 ft from the runway so was just getting ready to disconnect AP and fly in manually.

I have a FlyEngravity MIP with CP flight pro MCP+EFIS, Sismo Overhead and pedestal running scripts, jetmax TQ, FDS MX CDU, Simujabs Yoke.

I’m running windows 7, P3d 4 (latest version), prosim 2.03.

What can this be?
How do I debug it?
Could it be a hardware failure?

I would check the input debugger log and see if there is a fuel cutoff or other similar input being made that shuts them down. Could be a loose connection somewhere that randomly makes and then sends the input to Prosim.

Well I've now done 3 flights and not had it reoccur..  The only thing I did was to disable P3D voice control in the prepar3d.cfg file as I was testing this...

Will continue to monitor..
