Ongoing Projects Allow Early Lessons for UAV Ops
MIDCAS and ASTRAEA continue to allow development for collision avoidance and operations in controlled airspace.

Just as in the U.S. there is considerable interest in Europe in developing a solution to the sense-and-avoid problem for unmanned aircraft. A number of different programs are running concurrently under different national, international and industrial consortia, and while several have clocked up significant hours of flight test in surrogate or testbed aircraft, none have as yet flown on board an unmanned platform.
