It's the only TCAD system I'm aware of.


Eric ('n all),

There's also "Skywatch", I think by BF Goodrich. Same problem though,
expensive and consumes too much power for a glider. What would be *really*
good is if they came out with a portable ADS-B for cheap! But since that
won't happen soon - or ever, the only game left I'm aware of is passive
transponder detectors . . . and these have gotten mixed reviews until just
recently. The following is cut from a post on the Mooney tech group:

"Just got my TrafficScope TPAS VRX from Surecheck last week and
had a chance to fly with it.
Absolutely a first-rate product!!! Much, much better/different
than the earlier TPAS RX-110 version.

http://www.surecheck.net . . ."

The problem with previous passive detectors is they were based on signal
strength only, no bearing or altitude info. That, and some users experienced
a lot of falses. The new version mentioned above still doesn't give bearing,
but it *does* give altitude of the target and since it decodes this info,
can eliminate much of the falsing, alerts from overhead airliners etc.

I have no connection with the above company and don't have one of these
things to play with - yet. At $1200 . . . figured I'd wait some until there
are more happy customers.
