The project aims to extend the scope of the existing U-space ConOps version 4.0 into extended geographical scope (e.g., above VLL and eVTOL operations in the vicinity of airports, CTR, cities, and low altitude helicopter operations). It will make provision for functionalities and U3/U4 services supporting U-space integration and suggest SESAR Solutions, flight rules and airspace structure as elements of the ConOps. CORUS five will also raise relevant concerns, such as liability and quality of digital terrain models, common altitude reference systems and issues of convergence between Mean Sea Level (MSL) vs Above Ground Level (AGL) altitude references. The ultimate objective is to publish the fifth edition of the U-space Concept of Operations that supports safe, green and acceptable operations of crewed and uncrewed aircraft.
