ANSPs: Managing air traffic efficiently

Our airspace is like a dynamic 3D jigsaw puzzle. Traffic flows change, sectors exceed their capacity and departure procedures must be connected to the ATS route network. At the same time, airspace must be utilised efficiently. The results of the EUROCONTROL Performance Review Commission make this transparent. The problem is how to harmonise the objectives of more capacity and safety with the principle of cost-effectiveness. The DFS fast-time simulation can help you find the right solution.

In the past, airspace planning was mostly a reaction to changing requirements. Whenever an overload situation occurred, the sector boundaries were shifted or the sector was divided into two. The number of sectors, and thus the number of air traffic controllers needed to staff them, increased steadily. With the aid of its fast-time simulation, DFS has now proved several times that this can change. It has been shown, for example, that the number of sectors in the north German airspace could be reduced from twelve to ten without compromising capacity or safety. These results were achieved by balancing the loads in the individual sectors. The study is based on a traffic sample which forecasts that traffic will increase by 15 percent compared with today's figures.

This principle, which has been proved correct on a small scale, has now been successfully transferred by DFS to its airspace planning activities. It was possible to simulate comprehensive changes to the airspace before the changes were actually made.
In many analyses, critical factors with differing traffic volumes were identified, and proposed solutions were generated and validated.

Preparing for the future not only helps to face changes, it also helps to avoid unnecessary work. A fast-time simulation of the entire German airspace with a traffic scenario based on a traffic increase of 21 to 44 percent, for example, showed the critical points, but also made it clear that there was no need for action in certain airspaces.

Our simulations for air navigation services provide you with a basis on which to make decisions with respect to:

The efficient design of the entire airspace– particularly in the face of the expected traffic growth
The optimisation of the interfaces between approach and departure routes and the route network, and of the interfaces between the airport and the approach and departure procedures
The relocation or combination of control sectors or FIR
The optimisation of border-crossing air traffic
