...but as the IMC rating can not be added to a part FCL licence I was wondering what would actually appear on the licence, when said rating changes in April next year.
'Said rating' does
not change in April next year. Any 'IMC Rating' training and testing completed before next April will result in the licence holder being granted an IR(R). It is CAA Board Policy that the IR(R)
will continue for new issues after then, but at present no legislative means exists to facilitate this.
