Current processes, procedures and technologies in aeronautical communications do not provide the flexibility needed to meet the growing demands. Aeronautical communications is seen as one major bottleneck stressing capacity limits in air transportation. Ongoing research projects are developing the fundamental methods, concepts and technologies for future aeronautical communications that are required to enable higher capacities in air transportation. A study of EUROCONTROL states achievement of the aeronautical communications capacities in Europe in the next decade. Still, the main aeronautical communications is based on analog voice communication. The analog techniques are using the HF band for remote and oceanic regions and the VHF band is used for populous continental areas. There already exist aeronautical digital data links which do not increase a data rate of about 32 kbits/s but accessible satellite links. Table 1 lists available digital aeronautical data and satellite links. Moreover, the expected air traffic management (ATM) paradigm shift towards more strategic and tactical planning requires additional communication capabilities which are not provided by current air traffic control (ATC) and ATM communication systems.

Existing digital aeronautical data links (A) and satellite links (S). X Preface From Vision to Action Integrating existing and future communications infrastructure in a system of systems is the vision of the future communications infrastructure (FCI) to enable the goals for a safe, secure and capable future ATM communications. In 2003 ICAO expressed the need of new functionalities in aeronautical communications by an evolutionary approach. The Action Plan 17 by EUROCONTROL and the US Federal Aviation Administration (FAA) developed a comprehensive view of the overall needs in 2007. From 2007 to 2009, the EU research project NEWSKY (NEtWorking the SKY) addressed these demands by launching a first feasibility study for a global airborne network design and developing initial specifications for a new aeronautical communications network based on Internet technologies (IPv6). Also the EU research project SANDRA (Seamless Aeronautical Networking through integration of Data-links, Radios and Antennas) aims at designing and implementing an integrated aeronautical communications system and validating it through a testbed and further in-flight trails on an Airbus 320. Both, the FAA and the European Commission support intensive studies in this field, namely by the NextGen and SESAR programs. Of course, additional effort is and has to be spent in the area of future aeronautical data links, i.e., satellite, L-band Digital Aeronautical Communication System (LDACS), AeroMACS to facilitate the concept of a seamless aeronautical network. Outline of the Book This book assembles recent research results, emerging technologies and trends in the field of aeronautical communications. The book is organized in 5 parts covering occurring trends, aspects for future aeronautical networks, the challenges for the satellite component, emerging aeronautical data links, and visions for aeronautical communications. In the first part, Barba & Battisti give an insight of the recent SESAR program and the SANDRA research project including their main objectives, research activities and their collaboration. Current trends for datalink service providers (DSPs) are indentified by Durand & Longpre and also new emerging roles and its new players for future aircraft IT systems and associated ground components are discussed. Future aeronautical network aspects are covered in the second part. The integration of a service-oriented architecture in an aeronautical communications environment is shown in the chapter of Yifang et al. whereas the system wide information management (SWIM) ground-to-ground services are extended to air-to-ground information exchange. Muhammad & Berioli investigate the influence of the different data traffic characteristics by ATM communications to the transmission control protocol (TCP) and detailed analysis of the ATM traffic pattern and suggestions on the system design are given. Due to safety and security requirements an aeronautical communications system is a critical infrastructure.
