whopity..appreciate your input...despite having a copy of the ANO CAP393 it is a serious test of verbal reasoning ability to seek an answer to my original query within those documents. Nowhere in ORS4-894 or CAP 393 does it mention Permit to fly aircraft . Although the National licence continues to satisfy the Permit aircraft (and associated insurance liabilities)it is far from clear whether someone , for example , whose National licence expires and who elects to transfer to say a EASA PPL remains legally licenced and therefore Insured to fly the Permit aircraft.
