If you want a UK licence and you have an EASA PPL you must transfer your medical and licence from that EASA state to the UK. You cannot have a class 1 medical from one EASA state and a class 2 medical from another EASA state. Therefore, if you are doing the SOLI process you will need to transfer your medical and your PPL licence (you cannot hold a licence from an authority if the medicals are transfered to another authority). I am going to train in DFAS and I used to have an EASA Spanish PPL but I did the SOLI process and I changed to UK (the UK CAA is easier to deal with and more flexible).
For the SOLI process you need:
- Certified copy of your licence, medical and passport from a UK examiner.
- fill the required forms.
- contact your NAAs and the UK caa.
- and a lot of patience.
Good luck!
