The main objective of this project is to quantify the workload of an air traffic controller, developing a metric system with the information obtained through the Isis project, developed by the research group Icarus. In this project we used a support tool in the Isis system for the evaluation of the airspace in Europe, using the files from Eurocontrol of the Air Traffic in Europe. The development of this project it is motivated by the necessity of select an airway for the Unmanned Aerial Vehicle producing the minimum effect in the actual air space and the minimum effect in the stress of an Air traffic controller. Using the system provided, we analyses the air space in Europe, number of flight, sectors, regions, conflicts etc.... with these values we calculated an approximation of the stress produced to the air traffic controller and analyses the effect on the controller when we introduce an U.A.V. in the space, with his particular performance, and decide which is the best airway to reach the objective of the U.A.V. when we analyse a selected zone producing the minimum effect in the airspace.
