Through SESAR, Europe now has a concept of operations (ConOps) for the safe and secure integration of drones (U-space). Most operations to date have taken place in segregated airspace yet the need to integrate U-space into controlled airspace is increasingly recognised as an enabler to widespread use of unpiloted vehicles. Building on the success of CORUS and CORUS XUAM, the project will extend and mature the ConOps to include airspace that is not presently covered, e.g above very low level and in the vicinity of controlled airports.
