Sounds like you guys might be running out of things to argue about, so let
me give you something new.

Steven asked: "Let's say communications have been established and you're
transiting Class C airspace. The controller has spoken with several other
aircraft, but hasn't spoken with you since communications were established.
At what point are you no longer maintaining communications and thus in
violation of FAR 91.130(c)(1)?"

Remember that the controller's initial response to the pilot's first call
is: "PODUNK1234, Standby." The key is "standby". In radio-eze this statement
means: "I am aware of your presence, stay on this frequency and monitor for
any communications from me (controller)." Note that this does not preclude
communications initiated by the pilot.

So, communications are "maintained" until they are specifically ended. Under
normal circumstances, this will involve the controller advising the pilot
that he is leaving the controller's airspace and that a frequency change is
approved. At this point communications are explicitly ended.

Don't remember where I read this, probably one of the flying magazines, so I
won't be supplying any cites.

Have fun!

Well, if some time passes between one transmission and another, then
communications will need to be re-established.


Why?



How much time? Well, we can yak all day about that. Certanly
if the first transmission is on the ground before runup, and the next
transmission is in the air, it would be reasonable to conclude that
we are no longer talking about "the same conversation", and (as
per the original scenario) he can enter the class C upon the new
establishment of communications.


But that's not per the original scenario.

Let's say communications have been established and you're transiting Class
C
airspace. The controller has spoken with several other aircraft, but
hasn't
spoken with you since communications were established. At what point are
you no longer maintaining communications and thus in violation of FAR
91.130(c)(1)?
