So no sectors (forget the electronics were talking about controlling here)
Sorry but the electronics are an integral part of the "controlling" environment, like it or not. Of course if it is only the talking to planes that is the issue then some could run with just one person at certain times.
You may think it's a step backward to have 2 people on the sectors but I can't ever remember having to wait in excess of 30 seconds to get an answer to a phone call in AC. Common in TC with no dedicated co-ordinator.
Is it backward in terms of safety?
