4 (Refer to FAA-CT-8080-2G, Figure 23, area 3.) What is the floor of the Savannah Class C airspace at the shelf area (outer circle)?
A. 1,300 feet AGL.
This is not the correct answer.
Manned aircraft altimiters provide altitude in MSL, so the airspace and obstruction values are all in MSL.
When elevations are given two numbers, like 341 over (311), the top number is MSL and the bottom number in parenthesis is AGL.
