The regulatory framework for UAS is being developed. EASA recently released additional information on their plan for certifying UAS by defining the certified, specific, and open categories. While the certified UAS category is aligned with the DO-178C/ED-12C document suite for development, the open category does not have a software development standard needed for use and deployment and the specific category does not currently have a comprehensive compliant development standard identified to provide assurance as to the safe operations of the UAS. The continued release of information on UAS development and UAS operations by EASA provides an opportunity for a new software development standard that will be tailored to lower-risk UAS applications and the specific category defined by EASA. Moreover, certain lower-risk applications within the general aviation (GA) community might also benefit from a simplified software development methodology.
