MOA altitude range: what is the altitude range for all MOAs in Aero Center?

• A. 8000 MSL to FL180 inclusive
• B. 8000 MSL to but not including FL180
• C. 7000 MSL to not including FL180
• D. 9000 MSL to FL180

Answer: (B)

MOAs exist to separate military training activity from other air traffic, and in Aero Center all MOAs start at 8,000 feet MSL and go up to but not including Flight Level 180. The reason the upper limit is not included is that FL180 is the boundary to Class A airspace, where different rules apply and MOAs do not extend into Class A. So the range is from 8,000 MSL up to, but not including, FL180. The other options either set an incorrect lower limit or include FL180, which would place you in Class A.
