Pop-up IFR from Clearance Delivery

Indeed. To Andrew it was interesting enough to prompt him to post
a usenet question about it!


I think most of you folks are thinking of this clearance delivery
frequency
as being a separate position in the TRACON. That's extremely unlikely.
Any
airport with enough traffic to justify such a position is an airport
needing
a control tower. This frequency is almost certainly just an RTR located
at
the field because the normal approach control frequency for that area does
not reach aircraft on the ground. It's probably labeled as a clearance
delivery frequency instead of an approach frequency because some other
facility not so far away also uses that frequency and airborne use of it
would interfere.


At my airport it's definitely this way. The guy I talk to at Gray CD is the
same guy I talk to once airborne. That's why I would expect that CD could
give me a clearance just as readily as approach could. And if they told me
"contact FSS or contact approach once airborne", I would wonder about it,
just like Andrew did.

Seems like Roy Smith had a pretty good answer for it, though...
