"Best forward speed" approaches

I haven't done the math, but it seems like if you float down half a 2
mile runway after zooming down the ILS you're not going to be clear any
sooner that if you'd flown the ILS more slowly but made the first turnoff.

Yes you will. Nothing balls up a sequence like somebody doing 90 knots
over the ground.



Are controllers allowed to let the trailing aircraft get closer to
the end of the runway (with you on it) than they were to you while
you were in the air on the glideslope?

Three miles is the separation unless visual separation is used. If
visual is used there is no separation minima other than don't let them
hit. If the trailing plane is a single than 3000 feet is what's needed,
and you do not have to be off the runway. If it's a twin then it's 4500
and you still don't have to be off the runway. If it's a jet, or some
others like most King Airs, you have to be off the runway.
