From PARC, these are the
requirements that ANA have given them, for candidates:-
Total Time : 2,500 hours (on anything)
PIC time: 1,500 (on anything)
Preference: min 500 hours operating on a 2-crew (preferably) turbo-prop aircraft.
Preferably: A command rating on type. Most countries (except Oz and N.Z.) issue you with only one rating when you are endorsed - that being a Command endorsement. In their infinite wisdom, Australia and N.Z. differentiate between a Captain (command) and a non-command (it used to be called a 2nd class rating) endorsement, according to PARC.
To respond to
PPT - time from initial induction to "final checkout" is historically 7-4 months.
This involves a ground school that requires you to pass several subjects for your Japanese ATP, and Japanese Radio Operator's Licence.
Regardless of time on type, you will be required to do a full Ground school (and associated exams), fixed base, and motion on sim training, followed by a JCAB (and Company) sim check ride.
Line training will treat you as an
ab initio - after all, flying in Japanese air is TOTALLY unlike the air anywhere else on this planet!! - and you can expect at least 1 (but maybe 2) JCAB check rides, followed by about an hour of questions.
Now whilst all of this might SOUND daunting
the Japanese are very thorough with their training, and one MUST assume that you will not be presented for a check unless the INSTRUCTOR has done his work properly.
Nevertheless, it IS a somewhat "draining" experience, and there is (in)occasionally the poor unfortunate who bombs out.
