which frequencies are all?

But approach is not associated with any particular airport. Even
though a given approach may serve only one airport, it's not
associated with that airport, it's associated with a center.

How so? Approach tends to be located at the airport it was established to
serve, not at a center.

True enough in general, but 'round here most approaches have been
borged into either NorCal (nee Sierra, nee Bay / Sacto / Monterey /
Travis / Stockton / etc.) or SoCal Approaches. Same service, but served
out of anonymous barns somewhere in lovely Suburban Sacramento and the
even lovelier Southlands, well away from most of the airports they
serve.

Not that that's terribly relevant to the original point, but never
mind. It's just that the mental image changed almost overnight from a
bunch of people (some of whom you'd actually see occasionally getting
lunch from the local roach coach or talking at local meetings) sitting
around at Oakland or Sacto or Travis in buildings you could see every
time you flew, to a much larger bunch of people you never ever see, a
long way from most airports. Almost like a Center, in fact (but at
least I've *seen* Oakland Center and met some of the people there...).

This is why you may see approach and
departure on the same frequency.


I don't see the connection.

Me neither.

No one in this thread except maybe Bill Denton ever said approaches
were associated with (or "at") a Center.

However, it's true that there's a tendency in and around the larger
metropolitan areas of the US for approaches *not* to be associated
with, let alone at, a particular airport. I'm based in one such area.

Yes, and his was the message I responded to.

Some TRACONs in close proximity have been combined into single facilities
not located on airports, but approach control facilities are still
associated with airports. After all, providing IFR services to airports is
their reason for being.
