Final answer:
A Controlled Movement Area (CMA) is a part of an airfield that requires strict access control and communication with air traffic control, ensuring the safety and coordination of aircraft and ground vehicles.
Step-by-step explanation:
A Controlled Movement Area (CMA) is a specific part of an airfield that requires heightened security and control due to operational needs. This area often includes runways, taxiways, and other locations where aircraft operate. Additional focus is given to these areas to ensure safety and efficiency for both aircraft and ground vehicles. Access to these areas is strictly controlled, and communication with air traffic control is mandatory for any vehicle or aircraft entering the zone. It is imperative for all personnel and vehicles to follow the proper protocols to avoid disruptions or accidents.
When considering airport security or military installations, you may encounter terms such as confirmed surface-to-air missile (SAM) site, possible SAM site, and an airfield with MIG aircraft. These facilities relate to defense capabilities and aircraft operations, highlighting the importance of CMAs in such sensitive locations. A support facility for processing equipment might also be included within the CMA if it directly relates to the operation and maintenance of the airfield or the aircraft.
