It will require more controllers, more training and a change in the way we do air traffic control,
= very large cost...who pays?
if we can get an appreciable safety benefit
If hardly anyone crashes now, how do we quantify the safety benefit if hardly anyone crashes after?
Affordable safety says we are doing ok now. I've posted it before. Our controllers handle twice the number of movements per head per annum than their US counterparts. Perhaps they should be looking at our system if you want to talk efficiencies? You want their service, you need their numbers and infrastructure. See point one above.
Dick didn't crash, he didn't even nearly crash. He just flew an approach. He's just upset he had to exercise his IFR rating to do it. I thought that's what it was for.
