Uh, If you are on an IFR flight plan, you don't need to hear "cleared
for Class B". At least that is always the way it has worked for me.


If you are in IFR clearance you only got to distinguinsh two classes of
airspace: controlled and uncontrolled. You don't need to worry about the
classes of controlled airspace.

Well, you do have to worry about equipage to go above FL 240 (DME) and above
290 (RVSM).
