So, I understand finding floors and such when seeing something a fraction like 45/10 or 39/SFC, but I've been reviewing and gotten a couple of questions that look like this:
What is he floor of the controlled airspace overlying the Coeur D'Alene Airport?
The answer is "At the surface" but I can't figure out where it says that? The second question said this:
What is the floor of the controlled airspace overlying the Sandpoint Airport?
The answer is "700 feet MSL". Cant find that either.
