(Refer to FAA-CT-8080-2G, Figure 23) What’s the lower altitude limit of Class E airspace at Statesboro Bulloch County Airport (TBR)?
A) 887 ft. MSL
B) 700 ft. MSL
C) 1,200 ft. MSL

The answer to this question is A.

See how Statesboro Bulloch County Airport (TBR) is located inside the magenta vignette / fuzzy line? Remember that within those lines Class E starts at 700 ft. AGL. Not MSL, but AGL.

Looking at the section of text next to the airport icon, specifically, the bottom line where it says 187 *L 60-122.8 C, We know the MSL height of the airport is 187 feet. Meaning that if you’re standing on the runway of the airport, you’re at 187 feet mean sea level. Airport elevation is always charted in MSL like this.

So because you know this, you can add 700 ft. AGL to get to 887 feet MSL. The correct answer is 887 feet MSL. The correct answer also could have been 700 ft. AGL, but that wasn’t listed as an answer choice. The trick is to understand the difference between MSL and AGL and how they relate to each other, and not to get tripped up like many students do with answer choice B where it says 700 ft. MSL.
