Access to CMA typically requires what form of communications?

Access to CMA typically requires what form of communications?

• A. Two-way radio contact with the control tower
• B. Visual hand signals only
• C. No radio communication
• D. Communication through base operator

Answer: (A)

The essential idea is that access to the Control Movement Area requires direct, ongoing radio communication with the controlling tower. This setup lets air traffic control issue clearances to enter and move within the CMA and coordinate safely with other aircraft and vehicles. Visual hand signals alone aren’t reliable enough for CMA movements because traffic can be fast and coming from multiple directions, and ATC needs real-time, authoritative instructions. No radio communication would leave you without the necessary authorization, which isn’t allowed for CMA entry. While a base operator might relay information, that doesn’t replace the need for direct tower communication to enter and operate in the CMA.
