ATMACA project reaches key milestones and enters validation phase

The ATMACA-SESAR project continues to make significant progress towards next-generation air-ground communication systems, marking an important transition into its validation phase.

Developed under the SESAR 3 Joint Undertaking, ATMACA aims to enable seamless, resilient, and interoperable communication through an IP-based ATN/IPS framework. The project integrates key components such as Data Link Context Management (DLCM), Controller-Pilot Data Link Communications (CPDLC), Green Route Operations (GRO), and advanced Human Machine Interfaces (HMIs).

A core innovation of the project is the "flight session" concept, which ensures continuous communication and contextual data exchange throughout all flight phases, supporting smoother handovers and enhanced operational continuity.

Recent developments demonstrate strong technical and operational progress. Simulation results show that the GRO application significantly improves trajectory optimisation using real-time weather data, while protocol validation activities confirm high datalink performance, with CPDLC success rates reaching up to 98%.

In parallel, ATMACA has developed multiple human-centred HMI environments for both air traffic controllers and pilots. Initial usability assessments indicate positive feedback in terms of clarity, structured communication, and operational usability.

With the Exploratory Research Plan now in place, the project is moving forward with advanced simulations, human-in-the-loop validation, and a planned flight trial. These activities will contribute to the next phase of validation and support the evolution of future SESAR ATM solutions.
