Mate dont even start worrying about this sort of stuff yet!
Judging by your other posts, I think you need to find your nearest flying school, and sit and talk through the begining stages first..
Have a trial lesson, around £100, you might hate flying after that, chances are the instructor who takes you up is fully qualified..fATPL.. he/she will be able to answer all your questions..
Some airlines you pay for a type rating.
others will bond you, leave in a set time period and you will pay a % of cost.
