Spain's ATM research centre specializing in SESAR-driven air traffic management, trajectory optimization, drone integration, and machine learning for aviation.
CRIDA is Spain's dedicated air traffic management (ATM) research centre, serving as the R&D arm of ENAIRE (Spain's air navigation service provider). They develop and validate new ATM concepts — from trajectory prediction algorithms and airspace capacity optimization to drone integration and U-space services. Their work directly feeds into the SESAR programme, Europe's flagship initiative to modernize the Single European Sky, making them a bridge between operational ATM needs and research innovation.
Core contributor to over 20 SESAR PJ projects covering airspace management, trajectory operations, DCB, runway throughput, and ATM architecture (PJ09 DCB, PJ18 4DTM, PJ06 ToBeFREE, PJ02 EARTH, and many more).
Coordinated COPTRA (combining probable trajectories), COTTON (capacity optimization in trajectory-based operations), AURORA (performance analytics), and participated in DART (data-driven trajectory prediction).
Coordinated IMPETUS (unmanned systems integration portal), participated in TERRA (RPAS in ATM), SAFEDRONE (drone VLL operations), and contributed to PJ13-W2 ERICA (RPAS insertion in controlled airspace).
Participated in datACRON (big data analytics for mobility forecasting) and SafeClouds.eu (aviation safety intelligence); recent keyword clusters show machine learning and visual analytics appearing prominently from 2019 onward.
U-space and urban air mobility appear as top recent-period keywords across multiple late-stage projects, signalling active investment in low-altitude airspace management.
Recent keywords include CPDLC, LDACS, ADS-B, ADS-C, VoIP, and digital communications, reflecting work on next-generation CNS infrastructure within SESAR Wave 2 projects like PJ18-W2 4D Skyways.
In their early H2020 period (2016–2018), CRIDA focused on traditional ATM operational challenges: demand-capacity balancing (DCB/ATFCM), en-route airspace design, master plan execution for the Single European Sky, and trajectory-based operations. From 2019 onward, a clear shift emerged toward digitalization, machine learning, U-space, urban air mobility, and advanced CNS technologies like CPDLC and LDACS. This evolution mirrors the broader SESAR transition from concept validation to digital and autonomous aviation systems.
CRIDA is pivoting from conventional air traffic research toward AI-driven automation and unmanned traffic management, positioning them as a key partner for drone integration and digital ATM projects in Horizon Europe.
CRIDA operates in a dual mode: they coordinate their own focused research projects (10 as lead) in areas like trajectory prediction and capacity optimization, while simultaneously contributing as a third party in 29 large-scale SESAR industrial research projects — likely channeled through ENAIRE's membership in the SESAR Joint Undertaking. With 209 unique partners across 34 countries, they are deeply embedded in Europe's ATM research ecosystem rather than working with a narrow set of repeat collaborators.
With 209 consortium partners spanning 34 countries, CRIDA is one of the most connected ATM research organizations in Europe. Their network is overwhelmingly pan-European, reflecting the collaborative structure of the SESAR programme and the inherently cross-border nature of air traffic management.
CRIDA occupies a rare position as a national ATM research centre directly linked to an operational air navigation service provider (ENAIRE), giving them access to real operational data, airspace constraints, and controller workflows that purely academic partners lack. Their dual role — running independent research projects while embedded in the full SESAR industrial programme — means they can translate fundamental research into operationally validated solutions. For consortium builders, this makes CRIDA an ideal partner when a project needs both research depth and a credible path to real-world ATM deployment.
