Step-by-step explanation:
The Director, Airside Operations has authorized certain Airport Operations personnel and contract staff to operate free-range vehicles within the manoeuvring area of an airport. These individuals have specific boundaries defined for their area of operation and once the Air Traffic Control (ATC) has been notified, they are allowed to move freely within these limits. This permission is crucial for ensuring efficient operations and maintenance of the airfield while maintaining safety and coordination with the airport's traffic management systems.
