Interesting thread going... However, we find that visual approaches with visual separation works just fine over here. You do get folks to follow others and join the conga line. <shrug> I know that for some who are not used to such procedures it seems the wrong way to do things, but come on over and watch a busy push on a nice VFR day. It works very nicely. When the weather goes down a bit we then just go right back to vectoring to the ILS and not a problem. Sometimes when it is VFR but is a bit hazy we just stick them on the ILS to make it easier on everyone...
As for FAST and PFAST... We appear to be getting away from using it. We have found that it wasn't doing much more than a controller was already doing.
