The paradigm that the Sector-Less concept investigates is the trajectory-based individual control as opposed to the airspace-based sector control currently used. In this concept the role of the controller is radically different from the actual one: instead of having two controllers controlling one sector containing n aircrafts, one controller will be responsible for a number of m aircrafts, from departure to arrival terminal areas (TMA).
The aim of the SARGe project is to generate a route network which will both fit into the Sector-Less concept and provide an aeroplane with the shortest route possible. The approach chosen is to generate a suitable simple route network for Sector-Less and to improve it by using optimisation techniques such as a simulated annealing algorithm or a genetic algorithm.
Here is an example of the initial route network used. It's main characteristics are:
The best solution found so far is presented below. The average global extension of trajectories in comparison with the length of direct routes is worth 16% in this case (it worth from 7% to 11% in the current route network).
