Why is anyone getting TCAS alerts? TCAS is suppose to be the last line of
defense against a collision. If glider / jet traffic is regularly resulting
in TCAS alerts, then ATC isn't providing enough separation between
transponder equipped gliders and IFR traffic. This is a big issue that
needs to be brought up with the FAA.

Kirk,

Ironic that you talk about 22k cloudbases over Grand Canyon! That
is about the altitude of the midair on June 30, 1956, that got
Positive Control Airspace(now Class A) lowered from 24,000 to 18,000
feet! I put a transponder in my DG303 years ago. Most of the glass
ships at Warner Springs have transponders. There is no excuse for not
having a transponder if you do cross-country. The same excuses I hear
(not from you) are the ones I heard when I started power flying in
1973. Too expensive, blah blah blah.

It was extremely lucky no one was killed in that Minden midair. The
few times I have soared there(in rental ships) I have had close calls
with 121 carriers on the localizer for Reno or corporate jets going
into Minden. Flying wave the other day at Warner I was on LA Center
the whole flight. It was amazing the amount of carriers that vectored
around me or got TCAS alerts.

There is lots of traffic out there folks. Transponders are a great
safety device. The 0440 vs. 1200 has nothing to do with power output.
Per LOA with Reno the 0440 identifies you as a glider rather than an
airplane. It should be an FAR to have a discrete code for gliders and
hopefully will happen soon.

Happy Soaring, Dean "GO"

Mike,

ATC is tasked only with separating IFR traffic from other IFR
traffic. Even when VMC, IFR traffic is supposed to "see and avoid".
Tom

Ah do you fly much in high traffic areas, talk much to ATC? ATC
regularly issues traffic advisories to help separate all types of
traffic. If you fly a glider with transponder near places like Reno,
or Travis AFB, or ... traffic gets routed around you by ATC issuing
traffic advisories to other aircraft, wether IFR or VFR. The operating
procedures in place near Reno including for non-transponder equipped
gliders are intended to help ATC issue those advisories to IFR and VFR
traffic. That's why they are in place. Luckily people involved in the
Reno area seem to get that while important, see and avoid does not
work perfectly, and when you much high density fast traffic with those
invisible white gliders it works a lot less perfectly. And I'll repeat
again this applies to many more places than the Reno area.
