Thanks for the explanation. What if a job that you're applying for requires, say, a minimum of 1500 TT. Is this taken from your "grand total time", or "total aeronautical experience" time (which would be less than your grand total if you only added 50% of your co-pilot time). I'd assume it would be your grand total if total aeronautical experience time is only relevant for the requirements of the ATPL. Is this correct?
