EricThis is correct behaviour. There is no way in MSFS to easily tie the APU to the batteries so until you are running on engine driven generators you are on batteries.Gents - I hope all of you having trouble with lights and radios are checking that you are on generator power and not on batteries!! ;-)Cheers,

I cant speak for the others, but I'm definatly on generators, and its still cutting out after about an hour, reseting the generators/battery doesn't help, so I'm not sure

2 1/2 hours and not any issues yet. I will keep it going for another 3-4 hours. I do NOT have FSUIPC registered version for testing this.[h4]Best Wishes,Randy J.

I have the same problems. 2 out of about 5 flights. Does anyone from PMDG want to respond?

However I have not been able to solve the landing light problem with this. When I take-off no problem with the lights. Fly a short flight (EBBR-EDDF or EBBR-EGKK) and on landing no lights, no landing and no taxi lights.I hope you guy's can find a solution for this problem.Regards,Peter

That just woke me up again.
