One word: LASORS.
But because I'm so nice, here's the rest of the words:
The holder of a UK or JAR PPL(H), CPL(H) or
ATPL(H) is credited the examinations in Aviation
Law & Operational Procedures, Navigation & Radio
Aids, Meteorology and Human Performance &
Limitations and JAR-FCL Communications (PPL) (if
already passed). Please note: If no helicopter rating
has been held in the 10 years preceding application,
then the applicant would be required to pass all the
JAR ground exams.
