FRTO validity
Perusing the CAA FCL pages in their website the other day I noticed that it says that "Flight Radio Telephony Operator's Licences issued before Sept 2012 have a validity of 10 years".
So does that mean that any issued much earlier are now invalid after 10 years, despite them stating that they are valid for the life of the validity of the PPL to which they are attached? E.G. If your FRTO Licence is dated 1977 is it still valid? Is a re-test and re-application required to remain RT legal?
Is there an expert out there who can decifer the legislation please?
