The vertical limit for CBM MOA excludes which flight level?

• A. FL180
• B. FL200
• C. FL170
• D. FL160

Answer: (A)

MOA vertical limits define the ceiling of the airspace. Inside that vertical span, the MOA provides its protections; outside, the airspace is not part of the MOA. If the vertical limit excludes a flight level, that level is not within the MOA. For the CBM MOA, the ceiling sits below FL180, so FL180 is the first flight level not included in the MOA. Levels above FL180 (such as FL200) are also outside, but FL180 specifically marks the boundary that is excluded.
