What is the primary reason for restricting movement-area access to only perimeter and access roads?

• A. To minimize incursions
• B. To reduce noise
• C. To simplify recordkeeping
• D. To improve weather reporting

Answer: (A)

The main idea is safety: restricting access to only the perimeter and designated access roads is meant to prevent incursions onto the movement area, where aircraft operate on runways and taxiways. Unauthorized people or vehicles inside that zone can collide with aircraft during takeoffs, landings, or taxiing, so limiting entry to controlled points helps ensure only trained, authorized personnel with proper procedures and communications can enter. This focus on reducing movement-area incursions is why that access control is in place. Noise reduction or simplifying records or weather reporting aren’t addressed by restricting movement-area access in the same way, since they don’t tackle the core safety risk of aircraft intersections with nonparticipating traffic.
