Abstract

This work develops a set of high-level system architectures for an Unmanned Aircraft System (UAS) for the low altitude transport of a one ton payload within the ALAADy project. These architectures are further analyzed regarding their development effort. Based on the Specific Operation Risk Assessment (SORA) as Acceptable Means of Compliance (AMC) for the specific category of the new EU regulation for UAS, requirements are derived and processed into the architec-tures. An architecture for a certified system is developed for comparison as well. Overall four major architectures are found. Within SORA, regarding the use case of a large cargo drone, only flights over sparsely populated areas are possible. Consequently for flights over populated areas a certified system is needed. Re-quirements in SORA are based on the risk which can be modified by mitigations. Therefore, different levels of requirements have to be used for the same mission depending on used mitigations. Within the analysis of the development effort a nondimensional relative effort factor is found. As a result an ALAADy mission within SORA with limited mitigations and high-risk requirements has little dif-ference to a certified system. Furthermore there is a gap found between two adja-cent requirement levels. The development effort ranges from the least demand-ing to the most demanding architecture in half an order of magnitude.
