Airspace model simulation of Düsseldorf ACC - Phase I simulation report

The results found with this study show that considerable modifications to the airspace structure were required to solve the major problems encountered within the Düsseldorf FIR. The new ATC equipment would contribute to reducing widely the coordinator position loadings. Amended route network and sector plan, as initially proposed for this study, only brought a slight improvement as several radar controller positions were still found to be heavily or excessively loaded. The implementation of IFR procedures in Essen-Mulheim and Monchengladbach was generating considerable additional workload and delays due to the proximity of these airports with Düsseldorf.The evaluation of the concept of TMA sectors within the Düsseldorf airspace was very promising, even with future traffic. The efficacity of this organisation was at its best with the increase in capacity at Düsseldorf airport, achieved by a partial use of the second runwaythere.The final proposed ATC organisation to be implemented within Düsseldorf FIR should consider a further optimisation of the number of working positions (coordinator and radar controller), as well as the amendment of certain traffic flows in order to solve the remaining problems of heavy radar controller loadings on two enroute medium level sectors.This fine tuning of the AF31 study will have to be achieved during Düsseldorf ACC simulation - Phase II.
