Integrated Air Traffic Management and Avionics Systems
(CNS+A) for Environmentally Sustainable Aviation
Prof. Roberto Sabatini

Abstract and Bio-Notes
This paper discusses key contemporary issues in Air Traffic Management (ATM) and avionics systems research
focussing on one of the crucial challenges currently faced by the aviation industry: addressing the
environmental sustainability of the sector in an era of steady air traffic growth. The aim is to foster opportunities
for industrial innov ation and multidisciplinary research collaboration in areas of strategic interest such as future
systems for Air Traffic Flow Management (ATFM), Dynamic Airspace Management (DAM) and cooperativ e/non-
cooperativ e surveillance, tow ards establishing a coherent framework for the ev olution of the ATM sector in the
Asia-Pacific region and globally. Starting from SESAR/NextGen top-lev el operational and technical
requirements, this paper discusses recent adv ances in integrated Communication, Nav igation and
Surveillance/ATM and Av ionics (CNS+A) architectures implementing 4-Dimensional Trajectory Optimisation
(4DTO) algorithms, data link communications and enhanced surveillance technologies, as well as adaptive and
cognitive forms of Human-Machine Interface and Interactions (HMI 2), allowing the automated negotiation and
validation of aircraft intents for safer and more efficient air transport operations. As an integral part of this
CNS+A ev olutionary process, specific requirements for Unmanned Aircraft Systems (UAS) navigation,
communication and cooperative/non-cooperative Sense-and-Avoid (SAA) are being addressed in order to
allow the safe and unrestricted access of UAS to all classes of airspace. It is estimated that over 25% of
potential environmental gains (both in terms of gaseous emissions and noise reduction) can be achiev ed by
introducing new CNS+A technologies and associated operational procedures. While these technologies are
maturing v ery rapidly, their potential cannot be fully exploited without addressing the essential evolutions of the
associated regulatory frameworks and, in particular, the harmonisation of safety, security and interoperability
requirements affecting the design and operation of future CNS+A systems.
