My "stupid" transponder question now...

What do you guys do when given a squawk code? Once you enter the code,
is that it, or do you then hit the IDENT key, even if not requested? My
habit is to always hit IDENT so it makes it easier and faster (in this
area with realatively little traffic) to identify me positively on his
screen.


No reason to ident unless asked. It does not make it easier to identify
you under any circumstances.

Then why would we ever be asked to ident?

Possibly in a busy airspace... he may want to see where you are immediately
after assigning your squawk code.

When coming off the Phoenix Class B transition from south to north for
landing at Scottsdale, I've been told to IDENT by the Scottsdale Class D
tower when I've already been released by the Class B controller to squawk
1200, frequency change approved, etc.

I'd say this is a case of wanting to pick me out of the clutter since
Scottsdale uses simultaneous left and right traffic for arrivals to RWY 21
and the release from Class B comes when you are already only about 7 miles
to the SW of Scottsdale.

To make a legal radar identification the controller must see the code
change from 1200 to whatever code he gave you. If he doesn't see it he
will ask you to ident, this also qualifies. Same goes for a departure
off an airport in the middle of nowhere, all of a sudden the radar sees
a code, there was no code change, therefore an ident is required. There
are many letters of agreement that allow pre assigned codes. For
example for our local Help Flight helicopte is permanently assigned the
code of 0222. To make a legal ID the controller is supposed to have him
ident. In practice if I see a 0222 code I don't make him ident. It's a
trivial matter so I just skip it.

I often get asked to IDENT upon reaching a specific altitude when departing
IFR below radar coverage. Since it normally takes a few minutes to reach
the altitude where asked to do so, perhaps an IDENT is a way for the
controller to immediately be reminded that my aircraft has appeared, in the
event s/he has gone on to other tasks.
