Hi,

I'm having a short flight, and in the middle of the flight, the flight instruments just "quit" working (with warning flags covering readings of the instruments). 

I have seen this issue occurring in the beginning of the flight as well during instrument set-up.

Someone else posted that their generators were going offline mid flight. Can you check and see if this is true for you too?  

Hi,

Generators (including APU) seems to be working fine

Had this happen too, kicks the INS offline and cant figure out how to get working again.  

 

End up with a 'fail' light between the DC and AC standby bus.  Which you cant clear, even on the ground unless you reload the plane.

Thanks for your report. I know the team is working on a pretty substancial update for the L1011. I'll make sure they're aware of this issue.

Appreciate your patience!
