So see, an instructor who teaches that
there are class B,C or D airports is not performing to the CFI
practical test standards. Airspace is classified with the new ABC.
Airports are either towered or non-towered. Again not one official
publication will mention otherwise.

So the next time your talking about a specific environment say "its a
class Delta with an operating control tower".

But, I am not an instructor.
