Maybe I did not explain myself. I try again.
I know the requirements for CPL, IR and ATPL.
I know that many, after the PPL, do hour building to get to 150, then start the CPL and IR courses.
I was wondering if it is more convenient (or if it is just a matter of personal preference) to sit the ATPL theoretical exams and then, instead of doing hour building by flying cross country VFR in the USA towrds the 150 hrs, do the IR trining while logging the 150 to start CPL training.
In other words I am asking opinions on the two following routes:
PPL --> hour bulding to 150 hrs + ATPL theoretical exams --> CPL/IR training and skill tests
or
PPL --> studying for ATPL while training for IR --> ATPL exams --> IR skill test --> 150 hrs --> CPL training and skill test.
Thanks
