Please do not do that...

Hmm. Then I wonder what my transponder and PCAS equipped friends were
doing then to locate each other on a cross country flight? Radio
transmissions were as follows.

"Where are you?"
"I will give you an update. There."
"Oh, you are 240 degrees from me, 9.8 miles."

Later.

"I did get that update. Give it again. Got it. You are now 270
degrees, 5.5 miles."

Maybe I mis-understood what was going on? Maybe they were just "not
amusing" local ATC? If pressing IDENT sets an attention flag on the
ground radar display, it had to transmit something.

Haven't done it. Won't do it. Suggestion for others to do it
withdrawn.

Not an expert.
Never claimed to be.
Just smart enough to be dangerous.

I would like to understand this point about IDENT better.

As I understand it, a transponder TRANSmits when it is interrogated by
ATC SSR or when stimulated by TCAS, when it becomes a resPONDER to
that stimulus. Hence its name.

If IDENT is pressed when within reach of ATC, I can see how that would
flag it on their screen.

If not within reach of ATC SSR, does it transmit anyway, not in
response to anything?

Don't know the answer for sure, but the reply indicator on my Trig turns on
when I press the IDENT button. I think I'll send them an email and see what
they say.

Dave, Unless your sqawking 7700 then by all means ident away And if you
don't know what 7700 means you shouldnt own a transponder

What PCAS were they using that gave them direction?

Turns out I was wrong about what they had on board. They each had a
Garmin Rino, two way radio, GPS, tracker, etc.

Please continue to ignore my lack of knowledgeon some of these devices
that I have not been using. :-)
