The basic thrust of your analysis is correct for most controlled airspace,
John; but the clinker in the ashes here is that when a class C controller
calls your tail number, it is per the rules THE permission to enter unless
he specifically instructs you to remain clear...
What the AIM does not make it clear is that after being told to stand clear,
any subsequent tail number call, and especially with a phrase like, 'radar
contact established', barometer setting, etc., is clearance to enter per the
rule unless he repeats the instruction to remain clear, or assigns you a
heading, etc.. A point the FAA ought to clarify... I would, like you,
prefer that the AIM require the controller to say, ". . . cleared . . . " It
does not, that I can find...
