Then it’s OK for me to deliver this to you in no uncertain terms: The current practice was not always the practice and will not be the practice forever. Someone might wake up one morning and decide that it’s not really necessary to activate R578? at the same time as the others or the Class C. A potentially mind-blowing concept, I know, but something that has happened before and could happen again. Enjoy your coffee and the view! I’ll be too busy flying to ring.
