The Air Traffic Control - Trajectory Based Operations (ATC-TBO) project proposes to validate TBO SESAR Solutions for flights in the tactical execution phase for en-route and TMA operations, thus contributing to the finalisation of the SESAR Phase C developed in SESAR 2020 and the realisation of the Digital European Sky vision in SESAR Phase D. The results are expected to contribute to capacity, operational efficiency, safety, environment and cost efficiency. The SESAR Solutions, with the TRL/EOCVM levels at the start and end of the project are: • Solution #4: Improved automation in sector planning and separation management via enhanced trajectory predictions and controller tools, including the completion of Solution 53A from SESAR 2020 to V3 (Initial = TRL4/V2; Target = TRL6/V3) • Solution #5: Improved air/ground trajectory synchronisation via lateral and vertical complex CPDLC clearances to support TBO, including completion of Solution 56 from SESAR 2020 to V3 (Initial = TRL4/V2; Target = TRL6 /V3) • Solution #6: Advanced separation management function concepts and tools, making use of more reliable trajectory information and advanced use of datalink/CPDLC (Initial = TRL1/2 (V0/V1); Target = TRL4/V2) The ATC TBO project consortium - with EUROCONTROL as the project coordinator, and steering from the PMB and the SJU - brings together 14 ANSPs, 1 airspace user, 10 airborne and ground industry partners, 5 research establishments, and 1 university. 14 EU member states, Switzerland and the UK are represented. The proposal describes 21 validation exercises including real-time simulations, fast-time simulations, and expert groups. The 'design', 'development & validation', and 'data pack & maturity gate' phases are planned for the second half of 2023, 2024, 2025 and the first half of 2026.

SPATIO (u-Space sePAraTIOn management) will research the U-space services addressing separation between UAVs, in particular, strategic and tactical conflict resolution services and the relationship between separation and capacity in U-space airspaces. i.e., the relation with the Dynamic Capacity Management service.

The NETWORK Trajectory based operations (NETWORK TBO) project proposes to validate TBO SESAR Solutions covers all aspects of Trajectory management processes involving – but not limited to - Network actors. It covers both planning and execution phases. The proposed SESAR Solutions, with an indication of the Technology Readiness Levels (with the associated EOCVM level) at the end of the project, are: * Solution #1: TBO Planning and Impact on Execution. Taking as baseline FF-ICE/1 implementation in progress, this solution will develop focusing on the planning phase and the transition to execution including the EPP data improvement. (Target = TRL6 (V3)). * Solution NETWORK TBO-2: Strategic trajectory revision in execution. This solution will address trajectory management during the (strategic) execution phase, including a contribution to the development of the ICAO’s FF-ICE 2 TBO concept. (Target = TRL6 (V3)). * Solution NETWORK TBO-3: Improve both ATC and network processes through synchronization of network and local trajectories. This solution will aim in particular at improving information exchanges between the Network Manager and ANSPs in order to enable a reference Network 4D trajectory supporting coordination processes. (Target = TRL6 (V3)). The NETWORK TBO project consortium - with EUROCONTROL as the project coordinator, and with steering from the project management board and the SJU - brings together 9 air navigation service providers, 2 airspace users, 8 airborne and ground industry partners, 2 research establishments. The main 'design', 'development & validation', and 'data pack and maturity gate' phases are planned throughout the second half of 2023, 2024, 2025 and the first half of 2026. The NETWORK TBO IR project will be executed in strong coordination with European initiatives and projects related to TBO implementation as well as the ATMRPP ICAO working group ensuring complementary and maximising the R&D outputs towards implementation and standardisation.

The MITRANO project validates the management of mission trajectories and civil-military CDM at network level and in ATC operations, including advanced design principles for the military access to airspace, the DMA of type 3, and provides a technological solution for aircraft surveillance data protection, hence proving enhancement of civil-military cooperation and interoperability in ATM. Furthermore, the validated solutions will contribute to the digital transformation of European ATM, by using as core of information exchange, data sets created and disseminated automatically by technical systems, hence supporting operators and decision-makers to increase the efficiency of their activities. Nevertheless, the project supports the implementation of a Green Single European Sky by reducing the airspace segregations in the ATM network, hence enabling all categories of airspace users to fly more direct and efficient routes with a positive impact to the reduction of emissions. The validation activities are organized within three solutions: two operational and one technological, CNS related that ensure the development and validation of three overarching R&I topics: • Mission Trajectory in the ATM network execution phase through associated network management and ATC processes • Mission Trajectory with DMA of type 3 • Security aspects for ADSB (Automatic Dependent Surveillance-Broadcast) phase overlay The key operational expected results reside in uptake from civil and military ATM stakeholders of the MT validated concept and the associated network level civil-military CDM and on the DMA type 3 concept. Furthermore, ADS-B authentication layer and resilience to integrity attacks, and the definition of a management system capable of distributing authentication keys to aircraft is a key expectation. The expected outcomes will bring performance benefits in the areas of airspace capacity, environment, operational eficiency, civil-military coordination, and security.
