Airservices is Australia's air navigation service provider - we provide air traffic control, aviation rescue and fire fighting and air navigation services.

Air Traffic Flow Management

Ground Delay Programs

CDM Stage 1 entails the replacement of the Central Traffic Management System (CTMS) tool which services Sydney and Perth with an advanced ATFM application capable of simultaneously managing traffic flows at multiple airports. This new application is called Metron Traffic Flow.

Stakeholder interaction with Ground Delay Programs (GDP)

Metron Traffic Flow accepts real-time updates to schedule data, either via flight plan submission, airline day of operations changes to scheduled departure times, or ATC live data. As a consequence of accepting real-time updates, Metron Traffic Flow is able to display the most up-to-date demand/capacity information for any monitored airport, which in turn provides both airlines, airports and ATC with an enhanced capability to predict traffic management issues. Therefore to maximise the capabilities of Metron Traffic Flow it will be important that all airspace users update their schedules on “day of operations” as soon as schedule changes become known.

All airlines intending to operate into a GDP airport are required to submit operating details into the Metron Traffic Flow system. Airlines will upload a schedule directly into a web based interface, and smaller operators can contact the National Operations Centre who can enter their details into the system.

Aircraft and airport operators will be able to view the GDP information for affected flights via web based access to the Metron Traffic Flow tool. User login to this service is managed by Airservices.

Compliance management

The established ATFM concept of operations and business rules acknowledge the importance of compliance with an established GDP to ensure optimum efficiency and balanced distribution of delays for all stakeholders. They also acknowledge that, at times, there may be a need for flights to intentionally not comply with an assigned delay on the ground and absorb any remaining delay airborne (due to gate restrictions, etc.).

To ensure the balanced distribution of delays, GDP information will be made available to both Tower Air Traffic Control (ATC) positions and destination airport Flow Management positions.

This information will be used by ATC to advise flights when they are not complying with the GDP and, if necessary, take action to ensure compliant flights are not unfairly delayed by non-compliant flights. This will normally take the form of delaying non-compliant flights at the departure airport or during the enroute or arrival phase of the flight.

Documentation

Specific documentation on ATFM procedures and the Metron Traffic Flow System is available on the CDM documentation web page.

Metron Traffic Flow (MTF) Access

Participants

Metron Traffic Flow (MTF) web client access is provided to the following groups of users.

  • Aircraft Operators of regular services into Sydney, Brisbane, Melbourne and Perth airports
  • Airport Operators whose airport has regular services into Sydney, Brisbane, Melbourne and Perth airports
  • Other aviation groups who demonstrate a legitimate requirement for access.

Requirements

Aircraft Operators who operate a combined total of more than five regular flights per day into Sydney, Brisbane, Melbourne or Perth are required to have interactive access to MTF.

Each Operator will, on a daily basis, be required to upload their schedules, as well as tactically manage their fleet to ensure the optimum usage of available landing slots at all airports subject to a traffic management initiative (TMI).

Pilots of unscheduled flights planning to operate into Sydney, Brisbane, Melbourne or Perth during the hours of a ground delay program are required to call the National Operations Centre (NOC) on 1800 020 626, and Sydney ACA as appropriate prior to their flight to obtain a Calculated Off Blocks Time (COBT) for their departure.

Airport Operators will be assigned a passive read only access. This access will provide them with arrival and departure information for aircraft operating out of their airport.

Application

Application for access to Metron Traffic Flow shall commence by providing limited details to atfmu@airservicesaustralia.com, and shall include the following details:

  • Company name
  • Applicants full name and title
  • Phone number
  • Justification of requirement for Access.

Further information may be requested by the ATFM Operational Authority.

Following initial review the following two documents will be forwarded for completion:

  • ATFM System Access User Guide
  • CDM Data Sharing Agreement

The registration form at the rear of the User Guide and the CDM Data Sharing Agreement must be completed and signed before system access is granted.

Training shall be provided to aircraft operators by ASA consisting of a 1 day train the trainer course. Once this is completed and the aircraft operator has confirmed their company has completed in house training, access to the operational system shall be granted.

Once system access is granted, logins, passwords and the URL for access to Metron Traffic Flow shall be forwarded by the ATFM operational authority.
