In recent years there is a crescent interest for operating Unmanned Aircraft Systems (UAS) in new areas beyond the current reserved airspace. Such fact has forced regulatory organisations such as the ICAO (International Civil Aviation Organisation) to evaluate unmanned aircraft and to propose regulations for the expanded use of such aircraft. The definition of these regulations is a challenge for the ICAO and the academic community. This paper proposes guidelines seeking the integration of autonomous UAS into the Global ATM proposals from the aircraft viewpoint, the autonomous pilot and the aircraft interaction in GlobalATM. The possibility of integrating UAS into airspace depends on regulations that are yet to be defined and proper data with which to assure the flight safety standards of this new aircraft type.

During the last years, Europe and USA have made efforts to integrate Unmanned Aerial Vehicles (UAVs) in a non-segregated controlled airspace, aiming at their civilian use. So far, there has been no consensus on the criteria to be adopted by the community to, at least, keep the minimum safety levels as those already attained by international aviation. In this scenario, commercial aircrafts -with an increasing amount of passengers -and UAVs could be sharing the same airspace. There are a lot of concerns about the current navigation, control and surveillance system capacity as well as about the ability of analyzing and monitoring the resilience of the operating environment of the organizations and Authority Control to handle some dangerous situations caused by possible collisions between these aircraft. Based on this scenario, a research about UAV in Controlled Air Space is presented. The proposal is modeling UAV based on the Multiagent paradigm. Several scenarios and results are presented and discussed herein.
