The regulations on unmanned aircraft systems (UASs) changed considerably when Regulation (EU) 2018/1139 on common rules in civil aviation was introduced in the European Union (EU). The new regulation applies to nearly all UAS, regardless of the weight and type of the UAS, and devolved most regulatory powers from member states to the EU Commission and European Aviation Safety Agency (EASA). While the regulations enacted by the Commission (2019/947 and 2019/945) and the guidelines provided by EASA detail the provisions for operating and designing UASs, the implementation and procedural definitions were left to the member states and their nominated competent authorities. This paper investigates the differences in the implementation of UAS regulations in selected member states. Although, to a certain extent, most countries have adopted very similar approaches, there is also variation between the member states in their attempts to address different aspects of the new regulations. Depending on the member state, for example, easily and openly available services and the costs associated with mandatory procedures vary widely. Although nominally operating under the Single European Sky, easy access to airspace may also depend on which country the operation takes place in.
