Near miss from space junk.

None of the small aircraft I have ever flown has had TCAS.. Are you
sure you got that right ???

By "often used," I meant "when present on small aircraft, this is the type
usually used," because it's cheaper. I don't think TCAS is really present
very much on small GA aircraft, but I don't have actual figures. Since good
avionics represent a substantial portion of the total cost of an aircraft, it
follows that one wouldn't see advanced avionics that often on aircraft that
are not otherwise very expensive. Who would install $2 million of avionics on
a $90,000 aircraft?

OK, so TCAS reads transponder codes. I thought it was like a radar.

TCAS I (the kind often used on small aircraft) reads Mode C replies from other
transponders and builds a picture of the airspace from that, with moderate
accuracy. TCAS II (the kind mandated on large aircraft) also listens to other
TCAS systems to build a much more accurate picture of the airspace (if lots of
other aircraft are similarly equipped).


As usual you are wrong again. Try not to base your entire world on your
fantasies and guesswork.

Very few GA aircraft have any sort of collision avoidance, and I've
never seen any with TCAS I. The few that are out there that are
transponder based like the Monroy, Zaon, Ryan TCAD, L3/Goodrich
Skywatch are all generic traffic avoidance systems. They Skywatch
and higher end Avidyne TAS systems can be installed as TCAS I.

The TCAS I will send interrogations and it will locate aircraft
with more than "moderate" accuracy. You're confusing the lesser
PCAS and other traffic avoidance systems with TCAS I.

The difference is that TCAS II units talk to other TCAS II
units via the mode S datalink to coordinate resolution of
conflicts.

Would it have come up on TCAS?

Not unless they've started putting transponders on the space junk.
