ACROSS contributes to the secure and efficient integration of small Unmanned Aircraft Systems (sUAS) operations in low-altitude airspace, whether controlled (airport) or uncontrolled, where both manned and unmanned aircraft traffic coexists.

Specifically, the project consortium has developed a platform that enables UAS operators and pilots to acquire reliable and up-to-date information regarding no-fly zones and airspace constraints. It also allows them to submit flight plans for approval. Additionally, Air Traffic Control (ATC) operators and UAS Service Suppliers can authorize flight plans, obtain a comprehensive representation of planned and active flights within their responsibility area, publish no-fly zones, inform potentially affected flights, and request contingency maneuvers.
