Yes FL123, for exemple what will happened if i reached the FTSO requirements, will I need to reapply again?
Considering this is QR--- honestly speaking man, if you reach the FTSO requirement and they unfortunately happen to look at your file and come to the conclusion that you have reached the FTSO requirement. Then straight away you will be asked to re-apply again as a FTSO. I don't think they will change your file to FTSO. But if you have people in then that might take turn in your favor.
or simply imagine they call me earlier and I do not have enough hours required for the FTSO but already type rated on the 320? will it change anything?
This is not an issue at all. I know an individual who was an NTSO and was type rated on 320. He got in but was asked to do type rating again with QR.
