Toronto Pearson International Airport is adopting a new way of working called Airport Collaborative Decision Making (A-CDM). A-CDM procedures increase the efficiency of operations for all airport partners.

    The planned A-CDM trials have been suspended at this time. Further updates will be posted when new trials dates are available.

  • The A-CDM implementation is a GTAA-led initiative, in close collaboration with Air Canada and Westjet (our two principal carriers), the ground handling agents, NAV CANADA, and other airport partners. It is about sharing the right information at the right time with the right people.

    A-CDM allows for better common situational awareness through information sharing between key partners at the airport. Improved situational awareness allows the airline, its service providers and the airport to operate proactively. More accurate and regular flight status updates help airport partners anticipate arriving aircraft, prepare them for the next flight and achieve on-time departure, with optimum productivity of resources.

    A-CDM Benefits

    The most important operational benefits are:

    1. Improved predictability of operations – enabling enhanced planning and early discovery of potential problems, with more time to react and mitigate them.
    2. Reduced delays in ground movements – with the departure sequence optimized for the actual runway configuration and the actual infrastructure status, taxi times and gate hold times are reduced.
    3. Better utilization of available resources, maximizing utilization of assets – improved predictability allows for the reduction of planning buffers built in various processes.
    4. Improved pre-departure sequencing – resulting in a more efficient, planned and organized flow of aircraft towards the runway(s).
    5. Improved airport slot adherence.
    6. Maximized runway utilization – improved planning of departures and regulated queuing for the runways.
    7. Reduced number of CTOTs missed – improved planning of traffic flow towards the runways.
    8. Reduced apron and taxiway congestion – improved predictability, situational awareness and planning reduce wait times at the apron and on the taxiways.
    9. Enhanced apron safety – with the number of last-minute gate changes reduced, there are fewer apron incidents and accidents expected.
    10. Improved on-time performance.
