indian license to faa with 737ng
i have indian license with 737ng endorsed and i have roughly 1700 hrs on 737ng
and i also have faa ATP, but without 737ng rating. Now i want 737ng on my ATP as well ,so does that mean i have to do a full type rating again. Because i asked type rating school same question and they replied me with a course fee of 10000 USD, which says initial type rating. i m really confused about why should i do a full type rating, when i m current on same aircraft. please help !!!!!
