Banter welcome!
I raise the point because there has been discussion about this previously. I stated that if he 'lost' both engines and put out a mayday on COM1, nothing would go out. Someone else told us that with avionics on, you would have both radios. We were both correct, it all depends on what you want fitted to the battery and avionics busbar. I guess its a customer choice.
These discussions cause arguments and insults, but also educate.........
I suggest pilots go out asap and turn the generators off, see what YOU lose on YOUR aircraft. That's why it is sometimes healthy to speculate and not 'wait for the AIB report'. I know for certain now.
