Some FRTOLs were issued for the length of the pilot licence to which they were attached, whilst others were issued for the lifetime of the holder and a small number were issued for 10 years. I have one of each. If the FRTOL has expired then it needs to be re-issued. All pilot licences that were valid were reissued with ELP Level 4 for free, but licences that were not on record as being valid were not replaced. The original licence will need to be re-issued with ELP regardless. It can be converted to a UK Air Regulation Licence or could be reissued as a UK National licence or both. Stay on the high ground, renew the Class Rating at a DTO then apply for a UK Air Regulation Licence and ask for a UK National licence as well by ticking the box on SRG1104.
