What basis should ATC services be provided on?

ATC services are ideally provided on a first come first served basis to ensure fairness and efficiency in air traffic management. This method prioritizes the order in which aircraft request services, allowing for a systematic approach that accommodates the flow of air traffic. By adhering to this principle, controllers can assist with timely take-offs, landings, and route adjustments, reducing the risk of congestion and enhancing overall safety.

When services are provided on a first come first served basis, it helps to maintain a structured environment where pilots can predictably anticipate their service times, ultimately enabling a more organized airspace system. This approach promotes equity among all users of the airspace, regardless of factors like aircraft type or destination, which could lead to inefficiencies or unsafe conditions if used as a basis for service delivery.
