with an SIC type on the EMB 170/190 series (over 800 hours).
Unfortuantely the hours on the EMB 170/190 are only supernumeray as far as JAA is concerned as they do not recognise SIC as an appropriate qualification to log time in the aircraft. The hours do not count towards your totals.
Check JAR FCL 1 it is very clearly laid out.
If your type is current and you have over 1500 hours PIC then you are exempt the training requirement for the ATPL groundschool just apply to the authority you wish to take the exams under and take the exams. You don't even need a school involved so don't contact one as they won't be able to help unless you want to buy the books etc....
You are also exempt type rating training and can just take the ATPL skills test directly in the aircraft you are currently typed on - but that is IF you can find an examiner to do it reasonably, which must people struggle to do.
Must end up going to Europe or Florida (for CPL portion only) and take the JAA CPL then the JAA IR seperately. Each school will have its own procedures for students in your scenario.
