1. Since 5.3 nm is just over 6 sm, is this not contrary to the FAR's,
in that you can fly visual to the airport, even though at the map you
cannot see the airport?

You can fly (keep the dirty side down and navigate) visually without seeing the airport.

Just to clarify myself, you do need to see some part of the airport to
continue. It doesn't have to be the threshold.
