Which area requires Air Traffic Control Tower approval to enter?

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

Answer: (B)

The key idea is that access to the airfield movement areas is controlled for safety, especially where aircraft are actively moving. The Critical Movement Area is the section of the airfield where aircraft taxi, takeoff, and landing occur, and it requires explicit authorization from Air Traffic Control to enter. This is to keep vehicle and aircraft movements coordinated and to prevent runway incursions or collisions. That’s why this area is the one that needs ATC Tower approval before entry. The other options aren’t the same type of restricted area. One is a hazard surface (Foreign Object Debris) that you avoid, but it isn’t a defined zone requiring ATC clearance to enter. The term CMAV isn’t the standard designation used for the access rule in this context, and a runway, while also requiring ATC coordination, is encompassed within the CMA as the high-risk movement area being controlled.
