Capitaine, “Does the FRTOL exist as a standalone licence?”
Yes, unless you hold a UK licence where radiotelephone privileges will be endorsed in section XII.
Most UK glider pilots FRTOL are standalone
One does not need CAA medical or licence to fly gliders (a mere eclaration that they are fit to drive is enough to do gliding as sport), however, radio privileges in gliders outside selected frequencies require FRTOL which is usually issued as standalone unless pilot holds SPL, LAPL, PPL for other reasons
Thank you Qalupalik.
I’ll keep Regulation 6 in mind for the future, Tumbleweed
