FRTOL validity
StrateandLevel
"The FRTOL remains vaild provided it is used. If it has not been used for 10 years then you will have to revalidate it by passing the written and practical test. LASORS 2003 para B1.6."
This seems to contradict what it says on the licence itself i.e the licence is valid whilst the PPL is or words to that effect. Perhaps more recent ( but still > 10 years old) licences don't have that wording? I await clarification from the CAA but if past experience is anything to go by they'll just send printouts of documents on the website which don't really help.
