The Single European Sky is being introduced to improve the efficiency of flight and traffic operations by reforming the air traffic management system. Despite all of these technical advances, airlines choose detours to avoid high route charges. This mechanism is intensified when fuel prices are low. The single unit rate method has been proposed to counter this behavior, but it will introduce other problems for both air navigation service providers (ANSPs) and airlines. For instance ANSPs have to agree on the redistribution of revenues, and some airlines can be confronted with considerable hikes in the route charges. We propose a novel route charges method called FRIDAY (Fixed Rate Incorporating Dynamic Allocation for optimal Yield) that will i). take away the incentive to airlines for detours, ii). keep ANSPs in control of their unit rates, and iii). keep the new route charges for airlines close to the current route charges when introducing FRIDAY. We will show how the FRIDAY method calculates route charges for flights, and revenues for air navigation service providers. Furthermore, we will introduce a numerical method for setting the unit rates for the FRIDAY method. The expected benefits of introducing the FRIDAY route charges method are i). cost, fuel and time savings for airlines, ii). increased predictability, and reductions in traffic risks for ANSPs, and iii). reductions in emissions and CO2 for society.
