What are the implications for the pilot exercising his/her privileges for
the next 24 months?
There is no problem with the pilot exercising their privileges as they possess
a valid Rating.
As the CAA would not be aware of the pilot possessing a valid Rating
problems
might arise if any hours flown under the Rating's privileges
are to be used for Licensing purposes. eg Flying the PIC hours required
for CPL or MEP issue; or issuing a replacement Licence (with all Ratings) if
the original has been lost.
