Transponders

this system is not available on gliders, only on big airplanes
carrying passengers or military ones. It should emit hints to the
pilot for avoiding the collision based on altitude information, assuming
that the other aircraft is going to fly at a constant altitude, or
to follow the hint of its own TCAS, and neither is true for a glider.

TCAS/ACAS detects nearby transponder equipped aircraft. In the US and
western Europe, almost all aircraft larger than small twins now have
them. They will provide useful warning of the presence of a nearby mode
C equipped glider, whether or not the glider is flying straight and level.

No.

Besides, exactly how many gliders are flying with Mode C right now?
Maybe one 1-26 in North Dakota?

In the USA, hundreds, at least, but mostly in the southwest and eastern
parts of the country. Stick your nose into the cockpits at Minden, for
starters. Once the Microair and Becker became available, they were
flying off the shelves at Wings & Wheels, Knauff & Grove, and elsewhere.
Motorgliders are much more likely to have them, also. In our ASH 26 E
owners group, I think about half of the 30 owners have Mode C.

By the time the 1-26 in North Dakota has one, the rest of us will have
moved onto Mode S.

go to www.arinc.com and search for TCAS. You will find a very useful
paper describing the characteristics of the TCAS system.

After describing how wonderful it all is note the sudden disclaimer at
the end.

Could you be more specific, like a title? I get 32 hits and the few I
checked don't seem to be it.

Eric,

The file you want is tcas.pdf
It is about 500k. If you can't find it I'll send it to you.
