MUAC implements additional sectors in Netherlands airspace to meet increasing traffic demand

26 April 2018

EUROCONTROL’s Maastricht Upper Area Control Centre (MUAC) has implemented a third vertical sector layer in the western part of its airspace, in the Netherlands. The purpose of this airspace redesign is to increase capacity in the Delta sector by creating new sector configurations based on three layers instead of the previous two.

The three layers consist of a low sector (from flight level 245 to 335), a middle sector (from flight level 335 to 365) and a high sector (extending from flight level 365 to 660). This new vertical division allows for a better distribution of workload in the Delta sector and thus ensures a safer and more sustainable service.

In the past two years, traffic in the airspace controlled by MUAC increased by 8.9 % - far in excess of STATFOR traffic predictions. In 2016 and 2017 alone, some 150,000 additional flights were handled by MUAC air traffic controllers. In spite of the increasing productivity of air traffic controller to 2.06 composite flight-hours per controller-hour (+ 5% in two years), total delays (due to all causes like capacity, weather, military activity, staffing, etc.) went up to 0.67 minutes per flight in 2017. Delays over 15 minutes amounted to about 1.5% of the total traffic.

The third sector layer in Netherlands airspace will provide more flexibility in managing the traffic and will contribute to a further capacity increase in the summer - the busiest period of the year with traffic peaks of up to 5,800 flights per day in MUAC airspace. In 2018, a further 3% increase in traffic is expected in MUAC’s area of responsibility.
