Network Optimisation

Collaborative Decision Making (CDM) is an initiative aimed at improving Air Traffic Flow Management (ATFM) through increased information exchange among aviation community stakeholders. CDM comprises of representatives from air navigation service providers, airport operations (e.g. stand and gate management), ground handling services, aircraft operators and other stakeholders who work together to create technological and procedural solutions to the ATFM challenges faced by the network stakeholders.

The goal of CDM is a safe, efficient, secure and sustainable air navigation system that provides flight operators the flexibility to operate within their own capabilities and economic objectives. While supported by a variety of tools and technologies, collaboration transcends specific programs and fosters a more efficient and reliable way to achieve system goals by including ATFM stakeholders in the decision-making process. By sharing information, values and preferences, stakeholders learn from each other and build a common pool of knowledge, resulting in Air Traffic Management decisions and actions that are most valuable to the system.

Under the CDM principle, aviation stakeholders could view each other as “partners” collaborating with the common goal of delivering high-quality air transport products or services that are attuned to the needs and values of their customers; i.e., the flying public or other economic sectors relying on air transport. Adoption of the CDM principle could contribute to enhancements in predictability, flexibility, cost-effectiveness, participation of aviation community and environment. Significant environmental benefits are also delivered by lowering CO2 emissions and fuel burn by reducing the time aircraft spend in the runway queue.
