PJ18 4DTM Report Summary

Project ID: 734161
Funded under: H2020-EU.3.4.7.

Periodic Reporting for period 1 - PJ18 4DTM (4D Trajectory Management)

Reporting period: 2016-11-01 to 2017-12-31

Summary of the context and overall objectives of the project

Project PJ18 4DTM develops an innovative way of allowing the different Air Traffic Management (ATM) actors to have a unique and coherent view of the planned flight trajectory, guaranteeing that air navigation service providers, airport operators, airlines and the aeronautical community at large share a single vision that is harmonized and updated with the movements of both civil and military aircraft throughout Europe. It also allows traffic controllers to have more precise information for planning operations and managing traffic more smoothly.
This allows the different ATM actors to have a better knowledge of the flight intention so they can anticipate potential issues, correct deviations and better use their resources to reduce costs, increase safety, reduce CO2 emissions and better react to any unexpected issue the flight may have.
This is aligned with Trajectory Based Operations (TBO, which is used on flight efficiency, predictability, environment and capacity) concept, a broader international initiative where the projects contribute to its validation.
The project will also develop new tools to improve the availability consistency, quality and exchange of aeronautical and meteorological information that is both harmonized and top-quality, entailing a significant leap forward in improving the management of aviation operations.
The project is organized in several areas called Solutions, attending different aspects, like type of traffic, set of actors exchanging information or information domain.
The project works to support the development of the 18-01a Mission Trajectory (MT) optimised airspace user operations and aims at improving the civil military coordination in regard to the flight planning and the use of a specific flight plan format, the Operation Air Traffic flight plan (iOAT FPL). It will also work to improve ground air communication for the provision of Air Traffic Services, under PJ.18-01b MT in Trajectory Based Operation (TBO).
PJ.18-02a Trajectory Based Operations (TBO) is an ATM Solution aiming to reach initial maturity and intermediate maturity for Air-Ground (A/G) exchanges. PJ.18-02a will therefore concentrate on Reference Business Trajectory (RBT) management and the last phase of Shared Business Trajectory (SBT), once flight plan filing has occurred.
Solution PJ.18-02b FO IOP purpose is to share among all stakeholders a common flight plan and use it to share a common view of the flight, enabling greater flexibility in the interactions of controllers across ANSP’s (Air Navigation Service Provider).
Solution PJ.18-02c “eFPL supporting SBT transition to RBT” addresses the transition from SBT to RBT. While the full implementation of the business trajectory concept is addressed by TBO Solution, the eFPL supporting SBT transition to RBT Solution will address intermediate steps and building blocks taking into account SESAR 1 validation results on the Extended Flight Plan and ICAO FF-ICE increment 1 developments in progress.
Providing new or enhanced aeronautical (AIM) and meteorological (MET) information will contribute to improved situation awareness along a flight trajectory. The activities of the project focus on improving the quality, consistency of the information exchange and also the on-board use of this information with the objective to improve the efficiency of flight operations.
Objective of Solutions PJ.18-06a “Air Traffic Control (ATC) Planned Trajectory Performance Improvement” and PJ.18-06b “Tactical and Network Manager (NM) Trajectory Performance Improvement” is to support and enable TBO through the improvement of trajectory predictions for different ATM stakeholders, mainly for ATC and NM by taking into account all relevant and available data sources (legacy or not) such as radar information, Automatic Dependent Surveillance - Contract (ADS-C), Extended Projected Profile (EPP), four dimension (4D) Extended Flight Plan issued by the airspace user or Planned ATC constraints.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

PJ.18-01a has delivered its initial Technical Specification (TS) for intermediate maturity, followed by the development of the prototypes needed to support the validation exercises.
PJ.18-01b after coordination with 18-01a and PJ.18-02a started to define the functional requirements of the concept.
PJ.18-02a has delivered its initial draft Operational Service and Environment Definition (OSED V1) for initial maturity of the concept, looking at the update and revision of an aircraft trajectory in execution phase of the flight. In parallel, to investigate the potential for using datalink in TBO, 2 Expert Groups were formed bringing together a wide range of operational and technical expertise supporting the concept. Related Validation Report (VALR) reflecting these activities is on-going.
PJ.18-02b FO IOP has defined the requirements for the first IOP exercise focusing on basic functionalities of ENRoute to ENRoute flight data exchanges. In parallel, the initial development of the IOP software by industry has been started.
PJ.18-02c has finalized the requirements and developed the software that should be used for the first iteration of a validation to be held at Skyguide in April 2018.
The activities within PJ.18-04a&b established coordination with other SESAR 2020 Solutions which are in need of AIM and MET services/capabilities. Activities were initiated to clearly define information exchange requirements for service developments.
PJ.18-04c defined use cases for integrating AIM and MET information into the cockpit of the aircraft.
Solutions PJ.18-06a and PJ.18-06b started to build innovative solutions to improve the Trajectory Predictors initiating the development of technical requirements, technical validation plans and the prototypes and platforms to support the planned validation activities.
The main achievement of the work package so far is the production of Technical Requirements specifying how Trajectories computed at ATM ground systems (including NM) shall use the new data from the aircraft (such as ADS-C report...) to enhance the Trajectory Predictions performance.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

18-01 will improve and stabilise the military flight planning activities for individual flights including airspace management like the use of ARES (reserved airspaces) and additionally improving the network manager performance. It will also improve ground systems by advance use of A/G communication with military flights.
PJ.18.02 will provide a global strategy from operational and technical perspective of the TBO, by consolidating and harmonize all flight plan information among ATM stakeholders, improving the efficiency in planning and execution phases of the flights.
PJ.18-04 aims to improve the aeronautical and meteorological information exchange, which eventually will achieve enhanced situation awareness for all stakeholders of trajectory based operations. Positive impact on safety, flight efficiency and predictability could be envisaged. At the end of Wave 1, the other SESAR 2020 ATM solutions to which PJ.18-04 supports will be provided with improved AIM or MET information provision that would facilitate better decision-making in their operational scenarios.
PJ.18-06a&b Solutions expect to improve the accuracy of the trajectory of the flights enhancing the procedures and tools in the ground operations in ATM.
