There are a raft of boxes you need to tick for it all to work.
The sim needs to be approved
The TRTO needs to be approved. The TRI should be on the books of the TRTO so should be covered by that.
The TRE for LST needs to be UK or have done the briefing and payed the cash.
The TRE thats doing the base check also needs to be either UK or had the briefing and payed the cash.
Just heard of someone who is transfering there license to Ireland. Getting thier IR back using an ICAO IR to keep the theory valid then doing a type rating and getting it put on. Then they will be transfering the whole lot back to the UK again.
Utter madness.
