The increasing number of unmanned aerial vehicles roaming in civil and other environments poses new challenges concerning both regulations (a legal framework that is insufficiently mature yet, air traffic management (for unmanned devices) that is insufficiently standardized yet, compatibility with manned aircraft, that is not always happening adequately, and so on) and public (safety, security, privacy, accountability, and so on). The lack of unified international standards, as well as differences in national legislation, make those challenges even more prominent. In tackling this problem, the current position paper delivers an analysis of the abovementioned challenges, taking into account the important goal of properly integrating unmanned aerial vehicles in civil airspace and also effectively managing them.
