Hereâs my understanding of this situation. Itâs in an order I understand it so try to follow as best you can and if you have any questions I will try my best to clear anything up.
Article 2 of Regulation 2019/947 deals with definitions. Itâs just a dictionary, per sĂ©, of what the regulator can use in its basis to help regular people understand what is being referenced.
Whatâs really handy here is it says itself what the document is based upon: art. 2 Definitions
For the purposes of this Regulation, the definitions in Regulation (EU) 2018/1139 apply.
You can also find the same in the S.I.
The Secretary of State makes these Regulations in exercise of the powers conferred by Article 57, paragraph 1 of Article 58 and paragraph 3(a) of Article 127 of Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation.
Importantly, Regulation 2018/1139 governs aviation, this is very important because it does not have the scope for anything thatâs âindoorsâ. It is quite literally airspace safety. This means nothing in 2019/947 relates to flying a drone indoors. Or it didnât until the above S.I. was created back in October 2025.
Regarding the subject article: Article 2A Scope (operations in an enclosed area)
I believe the CAA are basically just closing a grey area. Indoor flight is not governed, but, the safety of people around sUAS is something the CAA are going to have a vested interest in. Essentially, if you bounce your drone off someoneâs head doing a warehouse fly through, the CAA is now being explicit in their interest of such matters.
ButâŠthis goes deeper.
Hereâs a paragraph right at the end of the S.I.
Article 2 is amended so that UAS with a maximum take-off mass (âMTOMâ) of less than 100g and UAS which are designed to be exclusively operated in areas which are wholly or mainly enclosed are excluded from the scope of the Regulation.
Could it beâŠthat this Article was actually only supposed to consider a working environment where (for example) a caged or micro drone would be flying about, potentially around uninvolved people, in a commercial setting? Like when doing checks in pipework. Has it inadvertently crept into an area it shouldnât by not further emphasising what it does, and does not cover in regards to flying in the Open Category? Purely speculation but a nice outcome if Iâm right.
