What are the credit time limits on my ATPL theory passes ?
A three year clock starts ticking the day you sit your first ATPL theory exam, whether you pass it or not. Between then and the end of the three year period you must have passed all seven exam subjects. If you do this, you are awarded a frozen ATPL, and once you reach the required flight experience for the issue of an Australian ATPL (ie: 1, 500 hours total flight time, 100 hours night experience, etc, etc), you may apply to CASA for issue of the Australian ATPL licence. There is no flight test requirement, as there often is in other countries. Should you NOT pass all seven exam subjects within the three years since the first sitting, you will lose all credits, and you must re-sit all subject areas, even recently passed subjects. The idea is that you continue to sit and pass subjects in a scheduled way, something that the airlines wish to see also.
