What is misleading is this frankly ludicrous statement, whoever wrote it should be prosecuted. Apparently it is becoming the norm in the UK to lie in order to further your own agenda, much like the orange buffoon.
Our licences are internationally recognised - including by the European Aviation Safety Agency (EASA) - both now and after 29 March 2019.
The CAA will continue to issue and reissue pilots' licences when they are lost, damaged, when details need to be changed or pilots' privileges updated as we do now. Over time, this would include removing references to EASA - a purely cosmetic change.
Purely cosmetic my ass. Yes licences will be recognised as ICAO licences, just like Namibian or Vietnamese licences, but the privilege to fly an F-reg or a D-reg is gone. The CAA know this and are lying through their teeth.
