Periodic Reporting for period 1 - DYN-MARS (DYNamic Management of Aircraft Configuration and Route Structures)
Reporting period: 2023-09-01 to 2024-12-31
The DYN-MARS project aims to minimise the environmental footprint of flights during climb, descent and approach through novel avionic functions and improved arrival routes and procedures. It enables, for the first time, a complete holistic solution that combines airborne with Air Traffic Management (ATM) improvements connected by enhanced communication capabilities. DYN-MARS builds on previous SESAR work through the development of the permanent resume trajectory function, the concept of dynamic deployment of arrival route structures, the DYNCAT project’s Flight Management System (FMS) energy management function and new air–ground data exchanges in order to enable the visibility of the flight plan at both ends. The DYN-MARS solution consists of both an enhanced FMS for aircraft and new airspace management techniques for Air Traffic Control (ATC).
Based on the communication by ATC of dynamically assigned routes or expected interventions, the DYN-MARS solution allows pilots to better plan their optimum vertical and speed profile while maintaining the required runway throughput. Downlink of the Flight Management System (FMS) computed trajectory allows for further improvement in the trajectory optimisation process between the aircraft and Air Traffic Control (ATC). The dynamic air traffic management procedures enable accommodation of these optimised flight profiles. The solution targets capacity constrained runways, during periods of varying traffic demand, and applies to medium, large and very large airports. The DYN-MARS solution sustainably reduces the environmental impact of aviation (CO2, fuel burn and the noise exposure of communities) whilst supporting the demand for high airport capacity and without compromising safety standards.

DYN-MARS has completed the first project period, meaning project results are not yet available. Activities have focused on developing the operational concepts, prototyping of the solution and defining activities to validate them. During the first project period regulatory requirements for DYN-MARS have been defined and standardization aspects concerning the novel avionic function implementation have been proposed. During several workshops, further requirements for the DYN-MARS solution on the SPR-INTEROP/OSED level and the concept of operations were developed, both for air (flight deck) and ground (ATC) side. The preparation phase of the validation tasks was mainly driven by the definition of the validation cases. Thirteen different use cases were identified for the five solution exercises in DYN-MARS. Within the validation plan, a detailed description for the validation of the complex interaction between the energy optimized flight enabled on aircraft side through the new FMS and the new airspace management on ground side. With the start of the prototyping phase, the FMS prototype was developed implementing the predefined avionic requirements and the implementation in the full-flight simulator framework was successfully started. In addition, the whole solution concept was further developed and the implementation on all different validation platforms (full-flight simulator, ATC simulation, air traffic fast time simulation) was started. The Dynamic Route Structures (DRS) concept was successfully transferred into the fast time simulation environment and outputs have been assessed. A major step was already done for the environment evaluation with successful tests of the connection of the fast time simulation tool outputs and the aircraft noise simulation model. The latter was also extended to provide more relevant results with additional perception-based acoustic metrics.
DYN-MARS primarily targets Airspace Users for efficient flights, ANSPs for cost-efficiency and green trajectory enablement, Network Managers, policymakers including the European Commission, ICAO, EASA, EUROCONTROL for regulatory updates, UAS and HAO operators for safety improvements, and society for reduced aviation climate footprint.
