Testing and evaluation aspects of integration of unmanned air systems into the national air space

Current developments show that the integration of Unmanned Aerial Systems (UAS) into the National Airspace System (NAS) is a process that will inevitably happen. Arguably, it may be viewed as one of the key milestones in the history of aviation. Whereas the majority of research and development efforts are being invested on developing the core technologies and regulations to enable such a leap, there are currently a number of gaps that need to be addressed to transition those new technologies to daily operations with no detriment to performance of the NAS and chiefly, to safety of the NAS. One of those gaps relates to the efficient Testing and Evaluation (T&E) methodologies and procedures that need to be applied to guarantee smooth integration of UAS with varying levels of autonomy. Another main gap relates to the performance metrics that need to be considered to support these new T&E processes. This paper elaborates on those two aspects and it shows examples of how to streamline T&E to accelerate UAS integration.
