When to acknowledge ATC

It's better than just a memory aid (though that's useful too). A readback
of information like that is critical to air safety. No big deal if you
get the last digit wrong, but if you mess up something to the left of the
decimal, that's serious business. Best to check and make sure you heard
it right the first time.


Altimeter settings don't tend to vary a great deal from one controller to
the next. If you're issued one that differs by more than a few points from
the previous then it's a good idea to check on it.



Of course, as the FAA has recently decided, if ATC fails to correct an
incorrect readback, the pilot is still to blame for whatever happens
subsequently.


The FAA never made any decision like that or changed the requirements for
controllers to verify readbacks.

I rarely get an altimeter setting from a controller anyway. I make a point of
picking up the setting from AWOS stations in flight and from ATIS before arrival
or departure. As long as you tell the controller you have the ATIS, about the
only time they'll give you the setting is as a gentle notice that you don't seem
to be flying at the altitude at which you're supposed to be.

No. They give you an altimeter setting almost every time you enter the
space they're working on initial contact. The point of this is that it
results in all aircraft in close proximity showing near identical altimeter
readings. You should also give the controller your altitude when you're
level after any change. Where do you fly where ATC doesn't give you the
setting on initial contact?

Almost every class B, C or D airport that I fly into. If on my
initial call, I give them the proper ATIS code (and the setting hasn't
changed). They have no reason to tell me (and everyone else) the
altimeter setting on initial contact. That's why ATIS was invented.
It reduces frequency congestion.

So you're speaking almost exclusively about towers? That I can see. If the
ATIS is good, no need for the altimeter setting. Other than towers, you
should almost always be getting a setting on initial contact.

Uh .... Just where do you fly that has an ATIS and *doesn't* have a tower?

I think his point is that one can receive an altimeter setting from ATC at
times other than dealing with an arrival in or flight through airspace
related to a towered airport (and thus at times other than when an ATIS is
available to provide the altimeter setting).

Above, I said "other than towers". I've corrected the ambiguity of my
initial statement. Again:

"Other than towers, you should almost always be getting a setting on
initial contact."

Do you only talk to towers? Possible. But tricky in some places. Anyway,
are you saying you almost always stay below Class Bravo? Another post
indicated you don't. So what are you talking about?

I can't recall getting one from TYS anytime I've mentioned having listened to
the ATIS.

As I clarified in another post, other than towers.
