Schedule coordination

We use a schedule coordination process to ensure our airport's capacity and air transport operations are managed as effectively and efficiently as possible.

Schedule Coordination is a way of managing and balancing airport demand and capacity through the application of a set of rules. Coordination involves the allocation of airport capacity to airlines and other aircraft operators to ensure a viable airport and air transport operation. Coordination is also a process to maximise the efficient use of airport infrastructure. Schedule Coordination, often referred to as ‘slots’, was implemented to balance demand and capacity at Perth Airport.

A  ‘slot’ is a permission given by a coordinator for a planned operation to use the full range of airport infrastructure necessary to arrive or depart at an airport on a specific date and time.

Without processes to balance demand and capacity and to coordinate the schedules of the many airlines seeking to operate at Perth Airport,  runway departure throughput decreases below its optimum during high demand periods, creating inefficiencies that erode airport departure and arrival capacity due to:

  • The particular demands of WA’s resource sector, which requires air services to depart during narrow periods in the morning during the week.
  • Airlines operating from numerous aircraft aprons (some of which are managed/controlled by Perth Airport, while some are managed by airlines).

In summary, airline air service schedules that are not coordinated result in “over-scheduling” and aircraft not being presented in an optimal manner for Air Traffic Control to achieve aircraft movement efficiency.

Perth Airport has introduced Schedule Coordination to balance demand and capacity, resulting in a higher level of control in high demand periods. The system is designed to ensure that demand is controlled in order to allow the runway to operate to its maximum efficiency, increasing overall capacity, minimising delays and enhancing airlines’ On Time Performance. Schedule Coordination provides greater certainty and predictability for airlines and their clients.

This administrative regime is based on the system laid down in the International Air Transport Association (IATA) World Scheduling Guidelines and World Slot Guidelines. These guidelines are used to schedule movements at many other airports around the world.

The system is helping to balance demand and capacity, ensuring that “over-scheduling”, the primary cause of delay, does not occur.

The system applies to all airline and aircraft operators departing from or arriving at Perth Airport - internationally, domestically and regionally.  Airlines and their passengers are positively impacted, as they have greater certainty about flight times.

Local business rules have been incorporated to deal with the unique profile of Perth demand. In particular, we had to design the scheme with the fly-in fly-out (FIFO) resource sector workforce deployment in mind.

The system is administered by an IATA approved coordination agent called Airport Coordination Australia (ACA).

Further details about the Perth Airport Schedule Coordination System, including how it will operate and the local business rules, are contained in the system document which has been provided to all airlines.
