Changes

The UK CAA issued FRTOL license can generally always be used in a UK-registered aircraft (i.e. with G-registration). For the time being, as long as the UK is part of EASA, the UK FRTOL will also be recognized in all other EASA Member States without any formal recognition process - so, the UK FRTOL license can also be used to make radio transmissions in an aircraft which is registered in Germany, for example. However, once the UK leaves the EU without further arrangements, it also automatically ceases to be an EASA Member State (unless it applies to re-join EASA and it commits to recognize ECJ rulings in the relevant areas , principally) - the application for FRTOL Authorization ("Berechtigungsausweis", 47 EUR in Germany) might be required. Nonetheless, all the UK FRTOL exams as well as tests will (probably) principally still be recognized after the EU exit due to ICAO-compliance, so that (apart from paying 47 EUR) they have not to be re-taken even in the case of a "No Deal"-Brexit.
