You should never hear a controller utter the words "Cleared to enter
(or cleared through)the Class C airspace". You do not need a clearance
to enter Class C, only establishment of two-way radio communications
and a Mode C transponder.


But pilots request clearance through Class C (and Class D) airspace
anyway.
What would you have the controller do, tell the pilot "unable clearance
through Class C airspace"? It's simpler just to "clear" the guy.



You lost me. If a pilot requests to transition a class C, the controller
has
several options: 1) ignore the call. 2) "aircraft calling, remain clear of
the class C." 3) "Cessna 1234, remain clear of the class C." 4) "Cessna
1234, standby" 5) "Cessna 1234, roger." 6) "Cessna 1234, altimeter setting
30.04." or even 7) "Cessna 1234 transition approved."


But the pilot didn't request transition through the Class C airspace, the
pilot requested clearance through the Class C airspace.



1, 2, and 3 are indications that the tranistion is not approved. 4, 5, 6
and
7 are clearances to enter. I agree with Tom that you will probably not
hear
"cleared to enter the class C" but, more to the point, you certainly don't
to hear it before entering the class C.

Why would you say it is simpler to just clear the guy? The simplest thing
to
do would be to ignore the call.


Because responding "Cessna 1234 cleared through Class C airspace" is simpler
than explaining to the guy that there are no clearances for VFR transition
of Class C airspace.
