the information is not below it is above!!!
the information is correct, why I know this is just because I recently coverted FAA ATP to JAA license. you can go much more in depth how to convert FAA to JAA, what I mentioned above is just the basic.
Offcourse if you have 3000 hours Total time and 1500 PIC time in an aircraft that MTOM was more than 30000KG, then you would only sitt couple of exams(air law and one more, not all 14) and be able to fly UK regirsterd Aircraft. Even this is very hard to get approved by the UK CAA. Good luck with that. They might give you validation for one year if you are lucky.
