King Air - Power supply cuts off after a few minutes

Featured Replies

Hey there,

I´ve got a problem with the King Air. I start the engines and then I switch GEN1 and GEN2 on. If I look at the upper panel with the power supply instruments, the Generators both work and supply power to my electronics. But after a few minutes all electrical systems shut down, due to a lack of power supply. If I then look at the mentioned instruments, the generators both do not deliver any electricity anymore.

Is that a bug, or do I miss anything concerning the systems of the airplane? I googled, but I don´t find anything.

Thanks, Al

You were posting in the FSX forum.  Is this actually an MSFS 2020 question?

Oh, I´m really sorry for that. Can you change it to the FS2020 forum or should I repost it there?

Never mind....I am the one who is wrong!  You are in the correct forum.  I was thinking of another member!  Carry on!  I think I need another glass of wine! 🍷

It may be the latest update causing your problem.

I’ve experienced that in the King Air seemly randomly as well, this was also prior to SU5.  I never did figure out the cause unfortunately.

Was thinking so, too, but I can´t find other people who discover that problem. And: If I start a landing challenge with the King Air, everything is fine with the electronics.

Turn off the ignitions after takeoff, with the little arrow (mouse cursor) pointed down, this will restore the power

I get this problem as well and was thinking it must be me doing something wrong - seems not then. 
 

or we are both missing something 😳
