SESAR 3 Joint Undertaking

Fundamental research for other topics

Funds curiosity-driven, TRL0 fundamental research on air traffic management ideas outside the other listed priorities.

The SESAR 3 Joint Undertaking, operating under Horizon Europe, funds one Research and Innovation Action for this topic as a lump-sum grant, with a EUR 500,000–1,000,000 EU contribution and a maximum project duration of 30 months. Proposals go through the standard single-stage EU Funding & Tenders Portal process, and winners must proactively share results with the other grants funded under the same

This call funds curiosity-driven fundamental research at TRL0 into new, innovative air traffic management (ATM) and U-space ideas that fall outside the three other named priorities in this call (ATM climate impact, digital flight rules, and quantum sensing/computing). It wants proposals that show real innovation or breakthrough potential and explain how their research aligns with the ATM Master Plan's vision and its five transformation levers: trajectory optimisation, data volumes, automation, dynamic airspace, and the evolving role of the human operator. Civil-military collaboration angles, such as military airspace access and interoperability, are also in scope where relevant.
