Yo
Just a query for all you pilots with 3 brains:
If you isolate either bus on the avionics smoke drill and are left with one generator, is there a problem using the APU generator if you get a further problem with the remaining engine driven genny?
i.e. If you use the APU generator, will it connect to the 'good' smoke free bus, or will it try & utilise the bus where the problem was?
We had it in a sim recently and it's a good discussion point!
Hope someone can assist.
regards
