DFS real-time simulation: The human factor

Air traffic control is made by humans. This simple truth becomes particularly evident whenever new systems or procedures are introduced. Even optimum planning and analysing are not sufficient in these situations. This is why more and more ANSPs avail themselves of the benefits of real-time simulation. DFS offers its customers a dual simulation platform: Air traffic controllers can anticipate future scenarios from 24 radar working positions for area control as well as from an advanced 360-degree tower simulator.

These state-of-the-art real-time simulators are successfully used to define airport layouts, especially to determine the location of the control tower, to assess runway capacities and to validate planned airspace structures, flight procedures and working procedures. During the expansion planning for Frankfurt Airport, for example, they were used to find the optimum location of the control tower. In the simulation, air traffic controllers can evaluate different locations and tower heights. Additionally, ground traffic handling is optimised by integrating new departure and arrival management systems. The tower simulator can be connected to the radar simulator so that it is possible to assess in simulated "live" operations complex traffic processes for all traffic types, both for arrivals and departures as well as en-route, with all relevant operational parameters.

The results achieved in the Frankfurt assessment were also used for a simulation of the future Berlin-Brandenburg Airport. The specific simulation platform created for Berlin can be used for public relations purposes and also ensures that movements in the air and on the ground can be tested and trained before they are put into practice. Furthermore, the location of the new control tower was determined on the basis of the simulations.

We conducted a study for Düsseldorf Airport with the scientific assistance of the technical university of Berlin. The study focused on the capacity of the southern runway. Realistic traffic situations showed that it would be possible to increase the number of movements per hour at Düsseldorf Airport without compromising safety. On the basis of these results, ground movements are now being assessed taking into account both runways of the airport.

In connection with the human factor, the DFS infrastructure for real-time simulations offers:

  • The optimisation of airspaces, procedures and routings
  • A sound basis for decisions and investments concerning airport planning
  • The validation of results achieved in fast-time simulations
