Ok. I guess at least one flight got its clearance when not inside an
approach plate, and prior to flight plan info being communicated.

I take it from your responses that this is normal procedure. Hmmm.
What are the criteria used to determine when flight plan info is to be
required first, and when not?

Steven's post said the initial callup included the A/C identification,
its current position, altitude, and its intended destination.
Would the controller need more flight plan information than that?
