The overwhelming sense I'm getting here is that the CAA is making it up as they go along and, every time some issue/situation that hadn't occurred to them comes up, change direction (again) to try and fix it. As things stand, I think we have a reasonably good idea for the next two years, but only guesswork about what happens around some rather key points once we actually get to 2028 that impact buying decisions being made right now. e.g., the post linked above to the DJI forum, directly quoting a CAA representative, only covers the transition period and does not state anything specific about what happens from 2028.
Maybe that's because they are working on the hope that vendors will start adding UK-class markings, and are leaving the door open to a further extension if they don't bother or approvals get caught up in red tape? If so, then that shows a lack of any kind of regulatory endgame *from* 2028 that they are working towards, or have confidence in achieving, - just they they have put in place something that will exist *until* they get there. What comes after 2028 is still open to wide interpretation and guesswork, which is clearly a problem for people looking to buy new drones between now and 2028.
There's another problem that still needs to be better clarified too (further rule/guidance changes incoming!): what happens if a tourist carrying drone without a UK-class mark but with an EU-class mark arrives in the UK in 2029 and wishes to fly it? There are three seperate issues here:
1. What the rules *say* (which, it not clearly worded, equates to "might imply").
2. What the rules actually *mean* (YMMV on whether the CAA will ensure #1 and #2 are equivilent).
3. What the pilot *believes* they mean (which also potentially includes crossing a language barrier).
Legally, the position might well be that the C-mark is no longer recognized (which is how I interpret things as currently written), and in that situation you must fly in
A3/legacy. Or maybe it won't be, and C-marks will continue to be recognised until the relevant specs diverge, assuming they ever do. The pilot, however, is going to find a lot of stale information online and could well believe that they can legally fly in
A2, or even in
A1. They'll probably get away with it if they do, but that's hardly the point - there's ambiguity there and the CAA can completely clear it all up with a single line definitively stating what the position will be post-2028 for drones that lack the UK-mark.
So, with the post-Xmas sales imminent, which will no doubt include a few good deals on drones, will the CAA give us a late present and make that all clear in time, or not? My credit card wants to know!
