Putting common interests in the driving seat

The ATM network is a complex system that involves the synchronisation of multiple operations and stakeholders. The Network Operations Plan (NOP) is a powerful tool that supports this process of demand-capacity balancing (DCB) by providing a common view of network performance indicators representative
of the current and anticipated network situation. The NOP enables individual actors to design local solutions with minimal impact on network operations using upstream network performance indicators. To encourage the shift from local to regional management and improve DCB, SESAR is developing a network performance
management dashboard tool (NPMD).

The candidate solution enables the pro-active management of network performance through the NPMD, increasing the network resilience through more efficient recovery plans to shorten the return to normal operations. The NPMD is designed to monitor the resilience of the network and anticipate, detect and monitor emerging disruptive operational situations across the system. The aim is to prevent an emerging degradation in one airport, or in one specific area in the en-route airspace, from having a cascading and potentially disastrous impacts on others. The candidate solution enables the pro-active management of network performance through
the NPMD, increasing the network resilience through more efficient recovery plans to shorten the return to normal operations.

  • Enhanced capacity
  • Improved predictability
  • Reduced environmental impact

In this context, SESAR is progressing the notion of collaborative constraint management in four dimensions (4D) – latitude, longitude, altitude and time. The aim is to consolidate DCB procedures in order to minimise the adverse impact on airspace user operations and on overall network performance. For example, in place of the current slot allocation procedure based on first-planned, first-served; the solution supports a coordinated 4D constraints management process, which arbitrates between the owners of the constraint, the actors involved in the solution and the overall network performance needs. It allows airports, air traffic control, the Network Manager and airspace users to agree on reconciliation measures. In case of multiple conflicting
constraints, a ‘multiple constraints resolver’ is designed to provide decision support to identify the optimum solution to satisfy all constraints.
