Hello everybody,Here is one thing that drives me mad: Please tell me I'm wrong...I always thought - even more, I' almost convinced that it is enough to either have the main battery switch or one of the generators switches set to "on" to get electrical power on the systems (with electric_always_available = 0).But now - regardless which aircraft I use - turning off the main battery switch disengages all electrical systems, also when all generators are working.Is this normal?, Does my memory really fool me? Or is there any general setting which I might have changed?Any help more than welcome!!Herbert

Noticed that too, haven't tested much more though. I remember before ( what ??? ) it would work with Gen(s) only.Roman

Hi Roman,No, it worked with all aircrafts. Never the less, thanks your answer.
