They might mean they are not receiving your xpndr. A power off reset
might do the trick.

They might also be prompting you that a new squawk code is coming, so
standby...

"Reset Transponder, (now) squawk 4512"

What they want is for your return and data to show up on thier screen...
<g>

Basically, this is the controller's way of politely saying that he's not
getting a good return from you. It's up to you to try to determine if
the problem is something easy (eg: xponder not on, circuit breaker off,
ifr code not entered, etc), or whether your unit is on the fritz.

Last time I got one of these, the problem was that my transponder
circuit breaker was pulled (clue to me should have been that my
interrogation light wasn't going on at all); I pushed the breaker back
in and it's worked fine since... I figured that my leg must have brushed
against the breaker and pulled it out, since I've had no problems since.
But I won't be totally surprised if the unit dies one day...

If you're getting a lot of these requests, and nothing obvious is wrong,
I'd suggest getting your transponder checked out...

They have no idea what they want... except that they aren't getting a good
code to come up on their screen and they either want to get a good one, or get
you to go away! <G>

You will hear a lot of meaningless phrases, such as "recycle transponder" or
"reset transponder" or whatever.

Since there is very little you *can* do, and still fly the plane, about all it
really means is:

a) Make sure you turned it on
b) If on, flip to standby and back
c) If they are getting the wrong code (and the right one is
dialed in), flip each digit by one and back.

By then you will have flown out of whatever shadow is blocking your signal
and they will most likely pick you up. {:>)

9 times out of 10, they are asking you politely to make sure
it is turned on and has the right code. It's sort of like them
giving you an altimeter setting when they notice you're 300'
off your assigned altitude.

When I fly civilian aircraft, I usually turn to STBY for a second or
two. Since this may not be practicable on your unit, flip-flop your two
codes and see what happens. When I fly military aircraft and a military
controller asks for a reset, I just just "roger" him or her and twiddle
my thumbs for about ten seconds until they say "we got your squawk
now!!"

In my case, they usually mean, "You forgot to turn it on, you boob."

It usually means that we are not receiving, or you have the wrong code
in the transponder.

It sure would be nice if the Terra transponder could remember the last code
set in non-volatile memory.

I wonder if reset means to turn off the transponder and turn it on again.
The startup test sets a few items that sometimes get scrambled. I used to
have a King transponder before I replaced it with a Terra. The King was
always giving trouble and frequently needed to be turned off and back on to
get it to work. Maybe that's what's meant by "reset". I don't see the term
in the AIM.

Of course "recycle transponder" could be a very good idea, throw it away
and get a new one.

Good point!!! I'd like to "recycle" my DME into a paperweight (if only my
airport had an instrument approach that didn't require it!).

The Controller is either not receiving your transponder or it shows on
the wrong code. If the later, the Controller should have said "reset
transponder, squawk X-X-X-X". When told to reset, I always switch to
standby, switch each diget to a different number then back to the
assigned code then back to on. If you're unable standby, use off.

Transponders are not particularly complicated electronic equipment and I
don't
know of any type that would materially benefit from switching it off or to
standby or
changing codes and changing back. The best a pilot can do is to look
VERY CAREFULLY at the current settings and determine if they are
appropriate to what ATC wants: correct code, correct mode and power
applied.

I interpret "reset transponder" to mean "set it to what it should be set
to if
it isn't already". (Of course I have NEVER set in the wrong code or
selected
the wrong mode or left the transponder on standby. No..)

Actually, I had one fail a while back in the *strangest* way -- it wouldn't
transmit a 2 as the last digit. Bay assigned something like 4642 (in fact,
I think that's exactly what it was -- amazing how these things stick), and
the transponder was sending 4641. Got the "recycle, squawk" suggestion
from Bay, did the officially sanctioned (and previously mentioned) "flip
all the digits". Still sending the wrong code. So I flipped it to 4643.
And Bay got 4643. *Aaargh.* Naturally, I was IMC (and fairly new at it!)
at the time. Fortunately, the controller was able to convince his computer
to give me 4643, and the rest of the flight went well. Until Stockton
approach wanted to give me a new code ending in... yup... 2. Some days
are like that.

Definitely a case of toss the transponder in the recycle bin. ;)

Whenever I hear this, it's usually just after takeoff and I've always
understood it to mean, "Hey, stupid! Would you please move the
transponder switch from standby to on?"

When I've been given "reset transponder" by SoCal Approach, the message
also included a new code. When they want me to turn it off and back on,
they say "cycle transponder".

Usually means cycle the digits for your squawk...in case the digits weren't
clicked securely into their detents on an old-style (like the ones I use)
transponder. I guess with a digital transponder you would just cycle the
digits to something else and then back to your assigned squawk. Or, as you
mention, flip-flop momentarily from you standby display.
