TRE or ATO
Bananaman, try EAA in BKK, have approved EASA simulator on ATO for renewal and training.
Depending on your authority, If they will accept, now clearly established by the CAA UK IN.04.2014, that if you are current on foreign license, and that you do not need any refresher training. Then, you may, have your authority approve the assessment of the TRE, who is by definition an assessor of your experience, and must assess, whether he is working for ATO or not.
Therefore, if the authority accepts that no further training is needed, and accepts the assessment of the TRE, then it follows that no ATO need assess the experience of the applicant for renewal. As the function of ATO is to conduct EASA approved structured training.
The opposite of the CAA UK is AESA ES, who will not accept any foreign experience and will require you to have all your supporting documents Notarized at the Embassy, and then follow the guidelines of EASA of 1 sim session of assessment and 1 per year of lapsed Rating. Seems that the fact that it is EU law makes no difference but to entrench the various authorities even more behind their Counters!
