Strategic event planning ensures the resolution of potential capacity/demand imbalances caused by events.

Strategic planning takes into account all isolated events (that might have an impact) to get a more complete picture on the network impact. Overlapping events (in time/areas) will be highlighted and can be assessed and coordinated before measures will be applied.

In the strategic phase, a toolbox with mitigation measures is used to minimize the impact on the network. Normally it is a combination of measures that will be used and which can vary for each event. These mitigations are coordinated with the impacted area control centres beforehand.

The toolbox consists of:

  • simulations,
  • staff planning,
  • configuration management,
  • network coordination,
  • Scenarios/regulations,
  • European Union restrictions, and
  • RAD Route Availability Document.

Events can be subdivided into different types. 

  • airspace improvement (e.g. Route Network Development Sub-Group (RNDSG) re-sectorisation, or free route airspace (FRA)),
  • airport related (e.g. runway works, or AD closures),
  • recurrent (e.g. art, sport, summits, or airshows),
  • occasional, or ad hoc (e.g. art, sport, summits, or airshows),
  • seasonal (e.g. ski axis),
  • military (e.g. military exercises), and
  • system changes/implementations (e.g. often from a transition plan).

Recurrent and seasonal events impact the air traffic flow and capacity management (ATFCM) network in a relatively predictable way, allowing air traffic management actors to optimize the network through appropriate Axis management. Occasional, or ad hoc events can generate additional traffic demand and possible local congestion. Military events refer primarily to military exercises. They are coordinated with the national Airspace Management Cells (AMC) and concerned area control centres (ACCs), the Network Manager and aircraft operators.


  • Specific event management support for air navigation service providers (ANSPs),
  • ATFCM measures (scenarios) to be applied during the event.
