This paper presents a new capacity management
concept where Dynamic Airspace Configuration (DAC) and Flight
Centric ATC (FCA) are dynamically applied together during the
Air Traffic Flow and Capacity Management (ATFCM) pretactical
phase. An airspace delineation methodology is also introduced
aiming at identifying when and where DAC or FCA can perform
better. This methodology entails the establishment of a dynamic
vertical boundary that divides the airspace in two different parts
where DAC and FCA are deployed. In addition, the geometrical
complexity metric has been considered to measure the traffic
demand and the sector capacity as an evolution of the current
use of entry counts or occupancy countsPostprint (published version
