Hi. Could someone please tell me how to get power to the AC Bus if there is no external ground power available/connected? I get the battery started, then the  GTC - no problem.  But closing the GTC Generator switch, whilst turning on the DC power, leaves the lower three AC Bus warning lights still showing. I can see no way to get the AC Bus connected, unless ground power is available, when closing  the External Power switch gets the AC Bus working. The guarded switch at the bottom of the upper overhead panel is the DC Bus Tie - no AC Bus Tie to be found (despite there being one mentioned in the manual - though the picture there is of the DC Bus as far as I can see).

I only downloaded this a/c the other day, so it surely doesn't need a patch of any kind - and I've spent a couple of hours now browsing the net to get an answer, with no result. Searching for "AC Bus" on these forums draws zero results.. Hmmm..

Thanks for any help here.

I think you are thinking of the generators - you have to do that to make them function. The videos on YouTube, which I saw before I posted, don't cover this. I think there's a glitch here: when the GTC and ATM are running, you should be able to get power on the AC Bus, but in the sim a/c you don't. I don't think there are any more switches or combinations of switches I can try!

Before any C-130 generator, including the ATM generator will produce power, they must be switched to the left to reset, then to the right to come on line.

MS/All,

for a C130H - no provision for other models here....

"The APU driven AC generator will power only the essential AC bus at any time"

from a C130 flight manual.

Baiscally, the essential will be powered by the APU, however, the main, Right and left hand AC busbars should remain unpowered, until the engine starts.

The other question - not from this post, but people have been asking, external power tripping the APU AC gen offline....100% correct, cant have both APU and external AC power, either one or the other.

From what I can see, the CS c130 is spot on in the electrical side of things.

Hope this helps clear the air. Let me know any further questions
