The PJ 14 CNS aims to specify and develop the future Technologies coming from the Communication, Navigation and Surveillance domains in order to support and manage the Operational Services, like the 4D Trajectory Management, in the future ATM System. Performance requirements for CNS systems are becoming increasingly complex and demanding and need to be considered as part of an integrated and holistic System of Systems, which includes air and ground CNS solutions considering convergence towards a common infrastructure, and a unified concept of operations, where possible. In parallel, CNS systems and infrastructure for both airborne and ground must take a more business- and performance oriented approach with efficient use of resources delivering the required capability in a cost-effective and spectrum efficient manner. All the activities performed in the PJ 14 CNS will be developed at European Level in order to avoid a fragmented approach and to ensure the interoperability as depicted in the ICAO Global Air Navigation Plan (GANP). The CNS technologies support the GANP in terms of: Airport Operations Globally Interoperable System Data Optimum capacity and flexible flights The PJ 14 aims to develop and improve solution, not already available, from the technological point of view to support the future ATM global system, according the timeframe addressed by the ATM Master Plan, mainly in: Surface Data Sharing to let a huge data exchange for an effective and efficient airport operations and awareness New Data Communications infrastructure to reduce the ATCo Workload avoiding misunderstandings and improve the efficiency Collaborative Air Traffic Management to support the ATCos, pilots, airport operators to improve the situation awareness Optimisation of Capacity, Flexible Use of Airspace and Turn-around operations to avoid congestion in ATM domain In the PJ14 all the main stakeholders are involved to ensure that all the operational needs are well considered.

Single European Sky the vision is clearly described in the ATM Masterplan. Reaching the goals for the European Airspace is only possible with focused technical developments on European level. The air traffic controller is the main player in the traffic management at tactical level. This project aims at providing the air traffic controller with more automated tools, thus freeing capacity for situations where human intervention is crucial. This provides even safer service for an increasing amount of traffic and with lower costs, as required by airspace users. This project is a part of the SESAR programme and addresses separation management. It will not only improve current conflict detection tools, but also develop new tools aiding the air traffic controller with resolution advisory and monitoring of flight trajectory. The project also addresses new ways of working together. Air traffic controllers traditionally work in pairs and in specific airspace. Could we change this to multi-planner setup, sector less airspace and seamless cross-border operations? Our project will ensure the research is developed to a stage where it can be used in operational air traffic management systems in Europe. This ensures that anyone can fly safer, cheaper and quicker in Europe in 10 years. Another really important issue is the integration of Remotely Piloted Aircraft Systems drones. Drones are new to European Air Traffic Management, and it is urgent to address concepts and technological developments needed to handle this kind of traffic safely. The companies involved in this project are the only ones that can deliver this kind of result. Not on their own but as the unique cooperation between air navigation service providers and air and ground industry. The capabilities to provide sustainable results usable throughout Europe by fast-time, real-time simulations and live trials ensures that developed prototypes are working in the context of future traffic and ATM systems.

EUROCONTROLs 2013 Challenges of Growth Report by 2035 more than 20 airports are operating at 80% or more of capacity for 6 or more hours per day drives ATFCM airport delay up from around 1 minute/flight in 2012 to 5-6 minutes in 2035. Whereas social, economic and environmental constraints impede building new runways, secondary airports are hindered by technical, infrastructure and meteorological limitations from absorbing additional traffic. EARTH unites key European aviation partners combining the right expertise and investment to address issues and drive deployment of operational and technical improvements to enhance infrastructure, increase traffic throughput whilst preserving safety and environment. Aligned with the ATM-Masterplan, EARTH focuses on separation and procedures to improve runway and airport throughput considering wake-vortex, weather, environment and noise whilst taking account of different traffic demand, future aircraft capability and airport configurations. Partners validate reduction of arrival/departure separations delivered through optimised runway delivery support tools and study new procedures designed to reduce environmental and noise impact whilst confirming increased runway throughput enabled by ground and on-board space-based augmented navigation systems including GBAS and SBAS. Partners investigate independent rotorcraft operations, fixed-wing and helicopter non-interfering simultaneous approaches, on-board and low-cost ground technology improving access to secondary airports in low visibility, optimising single and multi-runway operations in mixed-mode and dependent runway configurations and enhanced terminal airspace operations through curved approaches. EARTH supports the SESAR Deployment regulation and addresses European concerns on environmental sustainability, reduction of noise and fuel consumption and brings low cost improved access to regional airports making regions economically attractive with potential for new jobs.

DIGITS will contribute to reinforce the Enabling Aviation infrastructure key feature of SESAR 2020 by demonstrating the ATM benefits that can be realized through the use of downlinked 4D trajectory data in ground systems. The project proposes, in a close to operational environment and in fully representative operational conditions, a set of tightly coordinated development and demonstration actions of key airborne and ground stakeholders in Europe. The airborne industry will develop up to certification the worldwide first airborne unit capable of downlinking ADS-C data according to ATN Baseline 2 standard in compliance with PCP AF#6 (Initial Trajectory Information Sharing). The ANSPs and ground industry will build up pre-operational system platforms capable of receiving and processing ADS-C data including the Extended Projected Profile (EPP). These platforms will e.g. display the shared trajectory data to controllers on their working positions and integrate it in the Flight data Processing systems for the enhancement of the ground Trajectory Prediction. DIGITS plans to have revenue flights becoming available gradually as from mid 2018. These commercial flights will downlink ADS-C data to be processed in ATM ground systems of four participating ANSPs, covering together a substantial part of European airspace and air traffic under a variety of operational conditions. Demonstrations will be done in a shadow mode system set-up, supported by further offline analysis and post-processing. Project partners will make significant efforts to assess together with operational experts the benefits of initial trajectory sharing, its system impacts, potential human performance impacts and opportunities for further ATM performance improvements. DIGITS will bridge the gap between the early validation of the Trajectory Based Operations concept achieved in SESAR 1, also known as initial 4D, with successful flight trials in 2012 and 2014, and the deployment of PCP AF#6.
