Particular focus was put on the Brussels sectors in the vicinity of the REMBA navaid to assess if airspace changes made in May, 2004, resulted in a reduction of complexity. The study was conducted over two separate weeks; one in April, 2004, and the other in August, 2004.
The sectors were classified into three groups sharing similar complexity characteristics. The results are presented in I/D cards for each sector; these contain the quantitative values of the selected complexity indicators. The results of this study may be used to support safety management processes in MUAC to reduce complexity and increase safety and to support the MANTAS project.
