Strategic Deconfliction

Strategic Deconfliction ensures analysis and the maximum number of safe flights. The system forms the basis for improving flight safety and the number of flights.

Situation of air traffic controllers

To ensure a safe flight, there are controllers who ensure that the minimum distance between aircraft is maintained. However, to ensure that the controllers are not overloaded, a limited area is allocated to each controller team. These areas in turn reduce and limit the number of flights per hour.

EUROCONTROL is responsible for compliance with these airport capacity restrictions and the coordination of flights. It has the task of ensuring these restrictions. The organization also checks whether further flights are possible in a departure time window. If the minimum distance to be maintained is met and the capacity restriction is complied with at the same time, the departure times are reassigned. However, if the minimum distance between the aircraft cannot be guaranteed, a conflict arises. In the event of a conflict, the controller has the task of keeping the pilot and his aircraft at a distance. This additional work places an additional burden on the controller and reduces the capacity of his work area, resulting in additional costs.

Strategic Deconfliction

NASA has launched the Strategic Deconfliction flight safety system to reduce these conflicts in future. This conflict solution is based on data sets, sector boundaries, airport characteristics and trajectories. Trajectories are air paths that a single airborne particle passes through in a certain period of time. These components are entered into a diagram and the most efficient compromise is determined.

The data sets also include delay costs, conflict costs and constraints, all of which are included in the best possible trade-off between conflict reduction and delay. NASA has carried out a detailed analysis of the performance of strategic deconfliction. This basis then models the Air Traffic Flow Management (ATFM).
