Another case of where simulation doesn't match real life. By giving a
visual approach clearance, separation rules change.

Separation does not change because visual approaches are in use. It
remains the same unless visual separation is used. This is independent
of any type of approach clearance.



A controller can
funnel more airplanes into the approach. Otherwise he can't have more
than one airplane on the approach at the same time.


Not even remotley true. You are mixing and matching rules.
