Well obviously we are a little further down the line now and everyone will/should be aware that the PfCO is effectively dead with effect from July 1st this year.
The CAA will no longer differentiate between commercial and recreational flying so anyone is free to go out and operate commercially with the caveat that they must hold insurance.
Obviously there are other things to consider like which category you are going to be flying in and which sub category together with class of aircraft etc.
The A2 CofC will allow for higher MTOM aircraft to be flown in closer proximity and a GVC will enable flights down to 5m from uninvolved people (subject to the 1:1 rule).
Thankfully - it is quite straightforward, and dare I say sensible. The added 'bonus' is the EASA recognised certificate will be valid for 5 years from date of issue and will enable the holder to fly in any member (as well as the UK) state legally.
It should be borne in mind that there are currently no C0-C4 certified aircraft and so everyone's UAV they are flying at present will become legacy aircraft which cannot be certified retrospectively. (Lots of cheap secondhand DJI aircraft coming on the market soon!).
If anyone want to know more please shout although CAP1789 should answer the majority of questions.
