[net.aviation] Under the TCA

brent@phoenix.UUCP (Brent P. Callaghan) (06/19/85)

I have a question for any air traffic controller types
out there in netland.

If I'm flying around under a TCA floor with my transponder set
to 1200 and no mode charlie - how does the controller know
whether I'm below the TCA floor ?
There's no requirement for radio contact and I'm sure the
controller doesn't want to hear from me anyway if he's
stacked up.

If we ARE relying on the controller's good faith - then isn't
there the chance some day that somebody gets it wrong and flies
into the approach of a "heavy" without any warning from the
controller ?

Even if you have a mode C and are not in radio contact, the controller
responds to other traffic 
saying traffic at 5000 unverified.

The purpose of VFR corridors under the TCA  are to allow you
to pass through the area without having to contact a controller.
This is a convenience for both you and the controller, as he
is probably to busy to talk to you, and you don't want to wait
until he has time to help you anyway. I assume that you are
flying in VFR conditions under the TCA, in which case you
you should be relying on YOUR good faith and judgement to keep
yourself out of the TCA.

The Heavy should not be approaching in the area underlying the TCA.  One,
to avoid traffic not under the control of ATC (it usually is "controlled
airspace" in the FAA terms though) and two, because that's usually closer
to the ground farther from the airport than those birds want to fly anyhow.

My last few fun flights for new passengers has been under the NY TCA
up the Hudson at about 900-1000 feet.  I monitor NY center just in case,
and have heard myself described as traffic to others within the TCA, while
not contacting the controllers themselves.

By the way, there is a proposal by the FAA to REQUIRE all transponder equipped
planes to have them on at all times, not just when under ATC! This was metioned
in the last AOPA magazine, and is being fought but may well become regs.

Don't monitor center, monitor approach.

And it IS possible to get TCA clearances for sightseeing.  Don't
you think you'd be more comfortable at 2500 feet over the Hudson
than at 900 feet?

I missed this one -- was it in AOPA Pilot or in the Newsletter?

Would this regulation likely be any more effective than the SCATANA regs
which require that you constantly monitor an FAA voice frequency if your
plane is radio-equipped?

I wonder what would happen in the L.A. basin, where the FAA is pleading
for pilots who are operating in airport traffic patterns to "squawk
standby" because there are too many interrogators and too many
transponders and the replies are interfering with each other.
