Access to which airfield area requires ATCT approval?

Access to which airfield area requires ATCT approval?

• A. FOD
• B. CMA
• C. Runway
• D. Overrun

Answer: (B)

The key idea is that the movement area on an airfield is controlled by ATC, and entry into that area requires explicit authorization. This controlled space is called the Controlled Movement Area (CMA). Because ATCT controls this zone, anyone entering it must have tower approval to ensure safe sequencing and separation of traffic. Areas outside the CMA, like some safety or non-movement zones, aren’t entered under ATC clearance in the same manner. The runway is part of the CMA, but the term CMA correctly identifies the area where ATC permission is required to access.
