ATPL question.....help!!!
I am pretty sure that you still will have to take an ATPL checkride, even though you have all the other requirements. That being over 1500 hours total time, 500 multi crew with a MCC certificate, 500 hours on a Perf A aircraft and all the required written ATPL exams. Well that's what the requirements were when I last checked, and it was some time ago. That was to get a UK ATPL issued which was automatically converted to an JAA/ATPL
You must also do the skills test with an examiner who is qualified to sign off an ATPL checkride as not all examiners are. It can be done either in a certified simulator or in an aircraft. The ATPL checkride is pretty similar to an initial LST/IR but with a few extra requirements. You could get it signed off quite easily next time you have to do a skills test, e.g. recurrent training in the simulator, just make sure you get an examiner who is qualified sign off for licence issues.
Hope this helps, but for 100% accuracy check the UK CAA website.
Good luck
