How do you both know when the approach is no longer "practice"?
Is "practice approach" in the ATC manual? (I haven't looked.)


Yes.

When asked for an analysis of the scenario and the phraseology,
Boston didn't seem to recognize "practice approach".
In the discussion when I said "practice approach", he read it
back to me as "multiple approaches in VFR conditions".


Perhaps you didn't explain adequately, perhaps you weren't talking to a
sharp trooper.
