CADENA

Implementing information sharing and enhancing operational performance

CADENA – the CANSO ATFM Data Exchange Network for the Americas – is an initiative to promote and facilitate the safe and efficient movement of air traffic in the Latin America and Caribbean region through effective implementation of air traffic flow management (ATFM) and collaborative decision-making (CDM). These processes and procedures facilitate data sharing and promote a common situational awareness that is vital to the safe, efficient, and harmonised flow of air traffic.

How it works

CADENA members hold weekly ATFM planning web-conferences following CDM processes among regional ANSPs and stakeholders. Items openly discussed and shared among CADENA members, airlines and airports, include weather, staffing, combined sectors, equipment outages, traffic management measures (TMM), and airport configuration.

CADENA also operates the CADENA Operational Information System (OIS). This is an online platform to exchange information including ATFM Daily Plans (which document expected demand), planned traffic management measures, constraints, volcanic ash plumes, special events, and runway closures. The OIS also archives implemented TMMs which allows facilitates operational analysis and performance improvement plans.

The CADENA Regional Implementation Group (RIG), the body responsible for the governance, rules, and procedures for executing CADENA, has created the CADENA Air Traffic Flow Management Procedures Manual. This is freely accessible to all CADENA members and helps to effectively guide and improve day-to-day operations and longer term strategy.

CADENA in practice

CADENA members are trained in the process of conducting regional hurricane web conferences to inform CADENA members and stakeholders of potential impact. This process was put into practice on 20 June 2017, when tropical storm Bret moved over Trinidad and Tobago. This system provided the airline community with advanced notification of which airports would be impacted as the storm progressed along its track, and enabled them to adjust operations and secure air transport movements accordingly.
