... perhaps you might ask... why the written exam can be valid for 3.5 years for PPL issue (first exam, all others taken in 18 month period, then all valid for 24 months) for licence issue but only 1 year for FRTOL issue?
Yes, it's renewing a SEP Class Rating rather than having the Licence re-
issued (yes, I know the CAA call it 'renewal' of the licence, but that's because someone at the Belgrano cocked up the form).
BluntM8, LASORS 2004 stated:
Graduates of No. 44(or subsequent) JEFTS course, who are presented with a full accreditation course completion certificate (annotated with a green border), are credited with the practical Communications test. The RTF written examination will be taken as part of the full JEFTS course.
Graduates presented with a partial accreditation course completion certificate (annotated with a yellow border) are credited the practical Communications test only.
Why didn't you apply for your FRTOL at the time? Or was it a cock-up by whoever forget to get you to fill in the correct form?
If you either took, or were credited with, the RTF written exam at the time and have been using RT ever since in military aircraft, perhaps you could plead dullness and ask for the FRTOL to be issued accordingly? There is nothing in the accreditation terms which indicates any time limit to your military credit that I can find...
