Interestingly to mention DC bus certainly NEVER SUFFERED any influence. (the battery is always OFFLINE if gennies (redundant) are working normally.
Is this technically correct? Not having my flight manual at hand for the 777 but I thought the battery was online (so to speak) but just not carrying any load. I know the 777 is a different fish than the 787 but I am wondering why Boeing would have treated the basic battery logic any differently.
I know that offline might be defined as not carrying any load but I am speaking to the physical connection in this case e.g., the hot battery bus.
