Only if they fitted a transponder to the space junk!

OK, so TCAS reads transponder codes. I thought it was like a radar. You
learn something everyday! ;-)

I'm not always right,
But I'm never wrong.

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).

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

Pieces of space junk from a Russian satellite coming out of orbit
narrowly missed hitting a jetliner over the Pacific Ocean overnight.

not from a satellite and space experts said it could have been a
meteor."


Phwaaawh1 You don't want to pay any attention to what the New Zealand

Mmm, OK. Actualy, I've been pretty close to space junk coming down
myself on a few occasions. the most spectaculaor was the first, over
central Africa. It was like a meteorite, except much slower and
incredibly bright. Glowed bright green and lit up the dusk sky to the
left of the airplane like a lightning bolt. No way of telling how far
away it was, but it was definitely much higher than we were when it
ended it's pyrotechnics. This was the brightest one I've seen, but I
have seen others. As I said, they look just like shooting stars, but
it's the obvious speed difference and length of the burn as well as the
weird colors that distinguishes them..

How does he know how far away it was? Does the Airbus have radar that
would measure the distance? It would be impossible to tell visually.

Pitch up and use the RADAR altimeter.

Whee!

I've occasionally been within a couple of planetary diameters of space
junk. Worrisome. I've heard what those astronauts use instead of toilets.

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