I am asking this from an ATC perspective ... my experience as a pilot is that they would make helicopters fly the same approach but once they got the airport environment in site where do they go? Taxi over the taxiway at XX feet? Are they given "hold short" instructions? The whole thing is a big mystery to me.

Do they stay with tower or do they go to ground frequency even though they are still airborne?

And then for VTOL operations I guess those aircraft like the F-35B have wheels so they could land and taxi like a normal aircraft ... is that the procedure?
