As for the other types, yes, I'm aware having flown an aircraft with only AC gennys for over ten years and another with an APU/air starters for four years.
indeed, I’m aware of your experience and I was making my later comments to a wider less knowledgeable audience. However, your knowledge of the 109 procedures makes Ascend’s comment even more puzzling - if the switches are on during start, why is there a warning about turning them on after start? Plus, if the load is high, the gen must be on anyway, by definition (which is what prompted my question).
