Addendum:
The UK CAA have occasionally(sic) been known to make mistakes
when issuing Part-FCL Licences.
As well as confirming that any current Ratings are on the front, with
the correct (to the end of the month) expiry dates; it is also important
to confirm that any non-current ones are listed on the back.
If not then no ATOs could offer "Training as Required" Renewal courses
as they wouldn't know that the Rating had previously been held - and
they would have to offer a complete ab-initio training course.
