What I really don’t get in this whole US Airports optimization via visual separation strategy:
there are official definitions for radar separation. They were designed for a reason. They are being used to set airports capacities all over the world.
is it really prudent to increase capacity by saying that aircraft will not be separated via radar but have to do it themselves?
just the idea of doing parallel approaches on an airport that is not designed for that seems scary for me (as a non professional pilot)
