The Advanced Flexible Use of Airspace concept (AFUA) is the cornerstone of the European strategy for the optimum use of the airspace between commercial, military and general aviation. The integration of dynamic, flexible and near real-time management of the airspace as a tool for matching capacity to demand is an important enabler for effective network performance. This operational airspace management course looks at the Advanced Flexible Use of Airspace Concept and how it is integrated into network performance management both now and in the short-term future.
