NMOC

NMOC stands for Network Manager Operations Centre, a central facility within EUROCONTROL responsible for coordinating air traffic flow management across European airspace. Its mission is to maximize efficiency and safety by balancing demand and capacity, coordinating with national air navigation service providers, airports, and airlines, and implementing flow management measures when needed.

Operating on a 24/7 basis, NMOC gathers data from member states, airlines, and airports, monitors real-time network performance, and produces short- and medium-term forecasts of traffic demand and capacity. When forecast or actual conditions threaten network performance—such as adverse weather, industrial action, or unexpected disruptions—it coordinates and implements ATFM measures to reduce congestion and delays. These measures can involve adjustments to routes, speeds, or airport slots to maintain orderly traffic flow.

NMOC works closely with stakeholders to manage disruption, supports contingency planning, and communicates decisions through established channels. It analyzes performance indicators, publishes operational plans and updates, and participates in international coordination to promote interoperability and consistency across European airspace.

Located in Brussels, NMOC is a core component of EUROCONTROL’s efforts to manage the European air traffic network and advance the goals of the Single European Sky program. Its activities aim to improve predictability, reduce delays, and enhance overall network resilience through centralized planning, monitoring, and coordination.
