Using other freqs to communicate between planes or ground?

Where I rent/train, the two closest uncontrolled fields use 122.8 and
122.7 so the FBO squeezes 122.775 in between for calling inbound when
returning from the practice area or from cross countrys.

Not sure what you mean by "the FBO squeezes 122.775 in". 122.775 is a
frequency specifically assigned by the FCC to "Aircraft (Air carrier and
Private)" and to "Aviation support". That is, it's a frequency reserved
for communication between planes and FBOs (among other things), and would
have been granted to the FBO for that purpose (another FBO at the same
airport would have to use a different frequency).

Peter,

Didn't realize that 122.775 was tied to a specific FBO. But now that you
mention it, I've never heard anyone else ever use it, so thanks for
clarifying that. I used the term "squeezed" just to point out that it falls
between the freqs used at nearby airports.


The practice area (122.85) is close enought that you could, I suppose (if
you had a dilemma...), hail the FBO to ask for help.

The regulations don't say anything about 122.85 being usable as an
air-to-air frequency. Who told you that 122.85 is approved for use as the
"practice area" frequency? Is that published somewhere?


Can't say for sure that it's published in the official FCC/FAA sense but:

The flight school where I trained prints it on the same flipcard that has an
airport diagram with reminders for the tower frequency split, ground, ATIS,
unicom, PHX approach, and the above mentioned 122.775 if you need to hail
the FBO.

It must be printed on lots of things since I hear planes from Chandler,
Stellar Airpark, Williams Gateway and Falcon Field routinely declare where
they are in relation to known landmarks, their current altitude, direction
of flight and their intentions (PP maneuvers, simulated engine failure,
ground ref maneuvers, returning to xxx airport, etc...) There is some
"chatting" occasionaly when one plane thinks they might cross paths with
another and wants to be totally sure of the location or intentions of
another.

In the NE practice area (primarily used by FBOs at Scottsdale and Deer
Valley), they use 122.75.

Don't know about the northwest side of town.

The FBO freq is also handy if you need something from the office when you
are out on the ramp preflighting and you don't want to leave the plane
un-attended.

It is definitely a good thing to know the frequencies for FBOs.

Agreed. That was a specific detail which I overlooked on my long solo XC
(cause for a bit of "clenching") but the ground control folks at Yuma were
kind enough to provide it when I told them the specific FBO I was headed to
to get topped off.
