TRSA

I’ve just discovered that I’m going to need to fly through a TRSA
(Specifically, the Kalamazoo [AZO] TRSA).  Never having gone through
one before, I tried to read up on them.  Best I can figure out is that
they are like a class-D with RADAR surrounded by an optional Class-C.

So my choices going through one VFR are to just fly on through (as long
as I stay out of the small Class-D) or to talk to them and get the same
services I would in transitioning a Class-C.  Problem is – going to or
through a Class-C I’ve always contacted approach on the published
frequency (printed in the magenta box on the sectional) for initial
contact.  No box – no clue.  Anyone know how I choose an initial
contact frequency?  Any other info you think pertinent will also be
appreciated.

    Hi there.  I’ve worked a TRSA for about 6 years now.  Your analogy is a good
    one.  I’ll flesh it out a little for you:

    1.  A TRSA is not a class of airspace.  It is a service area which occupies
    whatever class of airspace happens to be around.  This usually includes a
    normal-sized class-D at the center (as you mentioned), surrounded by class-E
    airspace.

    2.  You participation is entirely voluntary.  The rules for radio
    communications are governed by the airspace class you are in.   Therefore, you
    will definitely need to talk to someone while in the class-D, but not
    necessarily in the class-E, and so forth.

    3.  One unique feature of the TRSA is its separation requirements.  
    Participating VFR aircraft are separated from other IFR and participating VFR
    aircraft.  It is in this respect unlike class-C.  You may be separated from
    other VFR aircraft by up to 3 miles under normal circumstances, and all of the
    wake turbulence separation standards must also be provided by controllers.

    Check the frequency tab chart near the legend.  There should be a list of
    approach controls depicted on the sectional with the frequencies that they
    use.

    [....]discussion about TRSA removed for brevity…

    I live/fly in Upstate NY, and we have two nearby TRSA’s, Griffis/Utica
    and Binghamton. We also have Class C. around…

    Even though SYR (class C) has some of the best controllers anywhere (they put
    up with me, so they must be good), for some reason I prefer to be in a TRSA
    than Class C…I think it is something about "volunteering" to do something
    rather than being forced to do it.

    I find the TRSA’s to be useful, friendly, professional. I actually do
    my flight plans to use the TRSAs as much as possible. It never hurts
    to have a primary radar scan looking for no-xponder aircraft.

    p.s. When flying in the SYR area, I like  NY10 (Michael Airfield)
    They have a newly-paved runway, and have just added 100LL fuel service
    for about $2.00/gallon. Airport is under the shelf of SYR class C
    to the north/west of KSYR.

    Correct a TRSA isn’t class anything.  It is just an area where you can get
    radar service (like a class C) but you don’t have to.  There is probably a
    Class D inside it somewhere, but that is separate from the TRSA.  If you’re
    going to land there it’s almost always a good idea to talk to the approach
    control.

    I’d talk to them.  I’ve actually flown out of Kalamazoo and everybody there
    seemed real helpful.  You can get the frequencies by looking up the
    primary airport (I think it’s got a name like Kalamazoo-Battle Creek)
    in the AFD.  If you have the little brown Airport Guides, they are real
    handy because they have little sector pictures with the frequencies (so
    you don’t have to think about if 230-030 covers coming from the north
    or not).  I also fly through the Harrisburg (PA) TRSA, it’s never been
    a problem to talk to them, and since there are airliners climbing out
    of the airport there, it’s handy to be talking to them.

    You have to look at the side panel in your sectional.
    That’s where you get frequencies/sectors for the TRSA, as well as class
    B w/o your TCA chart.

    Is this *always* true?  In the north-west sector of the NY Class B, all
    the charts I’ve seen say 126.7 is the approach frequency, yet they often
    seem to be on 125.5.  I’ve never seen 125.5 listed anywhere.  Unless I’ve
    just overlooked something, it’s not on the terminal, sectional, en-route,
    or approach charts.  It seems to be one of those bits of "local
    knowledge", however, that if you can’t raise anybody on 126.7, you just
    try 125.5 and more than likely they’ll answer there.

    All the TRSA’s I’ve seen have a note "SEE TWR FREQ TAB" under
    which the app/dep freq’s are listed.  This is at the top of the
    chart under "CLASS B, CLASS C, TRSA, AND SELECTED RADAR APPRACH
    CONTROL FREQUENCIES".

    Look in the frequency tabulation located on the sectional chart. Unfold the
    whole thing if you are having a problem finding it. It will list the tower
    frequencies in one table and the radar approach control frequencies in
    another. Also, look up the airport (AZO) in the Airport/Facilities Directory
    (A/FD) it should list the approach control frequency also.
