The FRTOL is required to operate a radio in an aircraft, it is not a pre-requisite for the issue of any pilot licence. However, since the exercise of professional pilot licence privileges usually also requires operation of a radio, it has become the accepted norm in the UK for an FRTOL to be held before issue of a CPL. Neither the FRTOL nor a Language Proficiency Endorsement (LPE) is a pre-requisite for the issue of a PPL or LAPL provided that there is no requirement to to use the RT while exercising the privileges of the licence.
