Some FAs seem to repeat explanations they hear Without giving it much thought. I’ve been told the power surge rationale too, usually on a B789. I’ve also been told it interferes with the navigation system—that’s a funny one; I’d just kick myself if they got lost on the way to the runway because of me. It’s also, apparently, a fire hazard, but fortunately only on the ground not in the air.
