Example given was:
"QF765 was flake 49er maintaining FL370, fagin at 23, filet next"
The syntax used here is also incorrect. FAGIN is the "Next Position" - for which the "Next Position" may be omitted - and FILET is the "Following Point" for which, in the example given, the term "next" was used.
ie. an International flight should say "Next Position FAGIN at 23" while a domestic flight may drop the "Next Position". The bit that is not required is the "Following Point FILET", which everyone, myself included, incorrectly says as "FILET next".
