Mrmum - there is a logical explanation to the apparent conflict. The provision of JAR-FCL 1.030(d) depended upon the willingness of the 'Authority' to grant "expressed permission in writing". If the UK CAA has now decided that it is no longer willing grant such a permission, they have achieved the same result without actually implementing FCL.1005, have they not?
