A MOA is established outside Class A airspace. Which option correctly describes the relation?

• A. Outside Class A
• B. Inside Class A
• C. Inside Class B
• D. Inside Class C

Answer: (B)

MOA stands for Military Operations Area, a type of airspace used to separate military training from other air traffic. Class A is the high-altitude block starting at 18,000 feet MSL. MOAs are designated outside Class A, meaning they are not part of the Class A airspace and are instead located in other airspace categories such as Class E or Class G (they can intersect other classes, but they do not belong to Class A). So, when a MOA is described as outside Class A, the correct relationship is that it lies in airspace other than Class A. For pilots, IFR traffic inside an MOA is separated from other IFR traffic, while VFR pilots should exercise caution and check current MOA activity and times on the chart.
