What must emergency response vehicles have to enter the CMA?

Emergency response vehicles must have approval from the Air Traffic Control Tower (ATCT) or an authorized vehicle escort to enter the Controlled Movement Area (CMA). This is crucial for ensuring that safety protocols are adhered to during operations at the airfield. The CMA is a designated area within the airport where aircraft movement is closely monitored, and access is strictly regulated to prevent any incidents that could impede flight operations.

By requiring emergency response vehicles to obtain permission from the ATCT or accompany an authorized escort, the process helps maintain the safety of both personnel on the ground and the aircraft in the air. This protocol ensures that emergency responders can act swiftly while minimizing the risk of interference with regular air traffic.
