Suppose you have to do a missed approach or just go around. What does
the controller want to see you as? You "own" the runway until you
terminate the code, so maybe the issue is when can the controller have
another plane start an approach.


I think Robert was talking about VFR flight following, not an IFR approach.
If it were an IFR approach, you'd only be instructed to squawk 1200 if you'd
cancelled IFR--but in that case, you're now VFR and you no longer "own" the
runway (and if you have to go missed, you're still just VFR; if you re-enter
the clouds, you're VFR in IMC).

You never owned it in the first place. A third scenario is when you are
practicing IFR approaches while VFR to an uncontrolled field. This just
came up at our place. One of the major college flight schools is based
at an airport 12 miles SW of here. They always do their last practice
approach into that airport. Since our facility over 15 years ago put
out a letter to airmen stating that we would provide separation services
to VFR aircraft on practice approaches we are required to provide that
service, traffic permitting, all the way to the airport. We used to
just terminate you and tell you to squawk VFR about 5-6 miles from the
airport. We can still do that but are on the hook for separation until
you tell us you have completed your approach. If you don't report the
completion we can take our best guess as to when you got to the missed
approach point as that is when separation would end anyways. Only then
can we allow a second aircraft to start the approach. Our other option
is to tell you that the approach is approved, maintain VFR, no
separation provided.
