5 weeks with the new air traffic management system At Wednesday 30 January 2008, Naviair was able to increase the ATC capacity limit to 70 % of normal capacity after implementation of the first big service-patch to the system. The software upgrade solved the most significant problems concerning assignments of the so-called transponder codes for the aircraft.
Thus in the coming weeks, the general capacity limit will be 70 % (75 % for the western sectors), which is a little lower than expected for this stage of the running-in period.
Naviair expects to implement another service-patch to the system in the middle of February in order to correct some of the significant inappropriatenesses identified at this time. One of these inappropriatenesses concerns the data exchange with other countries, which is not as automated as we would like it to be. This problem entails increased strain on the air traffic controllers due to frequent telephone calls. We also expect that the upgrade will correct the problems with some of the planning tools used by the air traffic controllers.
After the upgrade we will test and evaluate the effect of each service-patch, where after we will be able to inform about any capacity limit changes.
Air traffic controllers also need time off duty From the beginning of February, Naviair has gradually begun to allow controllers some time off for holidays or in lieu. In the last few months, this possibility has been suspended for air traffic controllers. The first six weeks' running-in of the new air traffic management system has required an extensive use of man-hours in order to fulfil the capacity plan. At this point we are facing the risk of situations where Naviair will not be able to maintain the optimum staffing at all times.
The actual capacity of the day will depend on the capacity limit and other conditions on the specific watch as well as the available staffing level of the day.
Naviair is still in daily contact with the Danish airline companies and cooperates about possible initiatives on the day that can reduce the risk of air traffic delays.
