Edoardo Filippone graduated cum laude as an Electronics Engineer in 1989. Since 1990 he is research engineer at CIRA, in the Flight System Department, involved with modelling, control of aircraft & space vehicles, trajectory optimization, flying quality analyses, and flight safety and human factors engineering topics. Since 2009, he has involved with ATM department research activities, and is currently head of the Air Traffic Management Lab. He has participated in European research projects, both within ESA and EC Framework Programs, and in SESAR WP_E exploratory research activities. He recently has been involved in several relevant RPAS related funded projects, such as ICONUS (Initial CONOPS for UAS Integration in SESAR) and in particular he coordinated the project RAID, one of the nine co-financed by the SESAR JU under the RPAS Integration Demo projects. In 2016, he contributed to the study DASA-Detect and Avoid State of the Art, entrusted by EDA. He is currently involved in the SESAR2020 PJ10.05 project on the IFR integration of RPAS in the non-segregated airspace.
The introduction of Remotely Piloted Aircraft Systems (RPAS) in non-segregated airspace over the European territory is a major objective for the European States, and a clear path through the evolving regulatory framework has to be identified at the European level. The Warsaw declaration supports the need for technology and standards development and urges “industry to develop open standard to support performance based regulation”. The Riga Declaration further provides principles to guide the evolution of this regulatory framework, one of them being the development of technologies and standards for the full integration of RPAS in European airspace. Detect and Avoid (DAA) is one of these capabilities, as clearly stated by the European Commission, SESAR-JU and EASA. Several initiatives have been undertaken in order to define the required DAA performance objectives and to develop enabling technologies, as well as to demonstrate their level of maturity, like MIDCAS and the Demo Projects of the SESAR RPAS program. Besides the relevant achievements of these initiatives, the DAA technology has not yet reached the required level of maturity to allow operations in non-segregated airspace. In this paper, a strong focus has been devoted to DAA solutions, suitable for dual use in Tactical and Medium Altitude Long Endurance RPAS (MTOW > 150kg) that operate in controlled airspace under IFR. Based on an assessment of the key DAA projects developed within and outside Europe, this paper describes the key technologies proposed for DAA systems and identifies the most promising technical solutions for the short and long term. The scenarios for RPAS ATM integration in the Air Traffic System and airspace classes are discussed, so to perform a qualitative analysis of the potential impact of the most promising DAA solutions on ATM. Finally, some recommendations for the way forward are drawn.
