Ground control vs. clearance delivery for VFR

I know the AIM is not regulatory, but I often find comfort in
following its suggestions in the hope that it represents genuinely
good advice. Do you think that this passage from the AIM represents
outdated policy that is no longer relevant?

Yes. I know that to be the case.

While that may be reassuring to *some*, others have had contradictory
personal experience.

For example, I have heard from a friend who worked as a safety rep for
a major airline at a major airport. Commercial airlines have had
their TCAS system yell to go around on short final when other planes
were taxiing or holding short but with their transponders on. So the
basic guidance to turn transponders on only on runways or when
airborne was reaffirmed. (Yes, some planes filter based upon radar
altimeters. That does not work at every airport, and not all
TCAS-type systems have RAs anyway.)

And, oddly enough, the yelling was listened to.

There's never a reason to have your transponder on any other setting
than ALT, unless otherwise directed by ATC.

How about to avoid the ****y tone in their request to turn it off 10
seconds after landing?


Never heard that, and I never turn mine off ALT.


Where'd you get bitched at?

Hi Dan,
Now that you got one of them there "fancy pants" airplanes G, does it turn
the ALT on and off for you automatically?

Uh-oh.

Now that you mention it, I believe it does.

The AIM statement and having the Xponder set to ALT when it is on are not
counter to one another.

Hmm. I've always assumed that older transponders needed a warm up period.
Otherwise, why does STANDBY exist?

They did.

Back in the tube days the transponder took a while to warm up and
most places didn't want everyone on the ground squaking 1200 and
cluttering up their screens.

So you turned it to standby so it would be warm by the time you were
ready to take off.

These days the only tube left is the pencil tube and that's fading
into history as transponders go totally solid state.

Plus nowdays as others have mentioned ground traffic is monitored.

They did but the new ones that don't still have the STANDBY position.

Why? Just inertia? Avoiding the need for "transition training" laugh?

I have yet to be told by any official source that I shouldn't have the
Xponder on Stby when I'm on the ground.

Never underestimate inertia. But my guess is that it brings the digital
display alive so that you can preset your squawk before going live.
