So on my recent CFI-A check ride, the examiner pointed to a Class C airspace on the sectional and asked what airspace existed at the airport at the surface. I told him it was a Class C because it extends from the surface to 4000 feet (typically). He then told me I was technically incorrect. He said that all Class C airspace are a Class D inside a C, because according to the FARs, a Class D is airspace which surrounds a controlled/towered airport. That was his reasoning at least...I then told him he was incorrect because a Class D does not require a Mode C altitude reporting transponder, in which case this Class C airport definitely did (because, well, its a Class C...). I tried to please him and just tell him I'll look into it, but I'm pretty sure I was right...This is coming from the same guy that also told me that servo trim tabs move in the same direction as the elevator...Anyone have any thoughts?
