You do not need a clearance to enter class D airspace (or class C for
that matter). Only requirement is radio contact.


To enter class C airspace, the controller must call back your call
sign.


Same with Class D airspace.

As Stephen is illustrating, radio contact is not RADIO CONTACT until
it includes your call sign.

"Aircraft calling Bumpkinville, stand by..." is not radio contact.

"November-6-9-Kilo-Yankee, stand by" is RADIO CONTACT. G
