Due to growing traffic volumes in aviation there is a need to distribute the daily traffic demand onto the available capacity to make the airspace system as efficient as possible. These measures are known as load balancing within the framework of Strategic Air Traffic Flow Management. Therefore ICAO recommends introducing Traffic Orientation Schemes (TOS) where the demand exceeds the capacity.
These TOS are mostly oriented on the ratio of demand and capacity on the one hand and safety on the other hand.
Additionally any TOS should take into consideration, that every single flight needs to be as cost or fuel efficient as possible to guarantee the most economic and environmental suitable use of airspace.
In this paper a methodology is shown and applied on the European Route Availability Document which enables to monitor the economic and environmental efficiency of a Traffic Orientation Scheme.
