Hi there,
No FAA has its own licensing systems... FAA pilots takes its PPL, CPL/MEIR... they can be qualified to look for a job at this stage.... then they will take the FAA ATP papers... if going into an airline.. most FAA pilots now will take the ATP papers as well before or after CPL/MEIR conversion. ATP consist of only 80 MCQs done with the FAA exam centre. which is different from the ICAO standard groups of papers consisting a series of exams.
US is a ICAO member but they uses thier own suplementary licensing systems... FAA is often unique and different from what ICAO countries. This can be seen in terms of airport lightings, air space regulations and their AIPs...
Pilot licenses on the other hand can under ICAO system of PPL, CPL/IR, MPL or fATPL. Full ATPL will be issued only with apporximately 1500hrs pic in a typed rated jet as accordence to the class of aircraft listed by ICAO Annex.....
Hope that Helps...
Great Way to Fly
