Paper 33 -- Simulated Free Routing Operations In The Marseille Uir: Results And Issues From A Human Factors Perspective

Human performance considerations are expected to be central to the efficiency and safety of advanced Air Traffic Management (ATM) systems, while increases in traffic and advances in available technologies are projected.Free Flight (FF) and Free Routing (FR) proposals to relax airspace and give greater autonomy to aircraft represent applications of possible new air traffic management paradigms. Relaxing route and part of altitude restrictions within a specific airspace is allowed by Free Routing (FR) operation.In FR airspace, users freely plan their routes between an entry point and an exit point without reference to a route network. This paper exclusively concerns Free Routing, and presents the main results of a study conducted by the DSNA as a participation in the Mediterranean Free Flight (MFF) program.The DSNA carried out an extensive experimentation in the third series of MFF large-scale real-time simulation (RTS3), with the object to acquire results on the Free Route concept in a busy Mediterranean area.The obtained results complement those coming from the first and second series of MFF real time simulations, as well as the other simulations in the RTS3.The DSNA simulation trials, denominated RTS3/FR in the rest of this document, took place in January and February 2004 in the experimentation facilities of its research center in Toulouse. For the RTS3/FR, controllers were provided with an original set of tools designed to assist them in dealing with Free Route traffic, according to operational requirements specifically defined for FR. Eleven controllers from the Marseille air traffic control centre, two military controllers, and six pseudo-pilots participated in the simulation trials. These trials consisted of eighteen measured exercises.The main lesson of this specific RTS3/FR is that Free Route as simulated is not adapted for high levels of traffic load.In case of sufficiently low traffic, the concept would be usable on condition that sector design is improved, and that controllers' tools can be made perfectly reliable. The paper examines FF and FR cognitive implications, then introduces the experimental set up, gives information on the main aiding tools, and presents the main results of the simulations from a human-factors perspective.
