I'm confused too.
1. Get PPL
2. You can start studying for CPL/ATPL exams
3. Build hours up to 150(?) hours (including all the P1 requirements) mean while.....
4. Sit exams and pass them.
5. Do CPL flying course.
6. Write CV and post.
7. Do IR or get sponsored for IR and get NS job. Reality check - no North Sea jobs, build hours to instructor course (250hrs P1?)
8. Do instructors course
9. Get job as instructor
10. Wait for NS job or build up to onshore position.
11. If going for ATPL do IR and keep it current or resit ATPL exams if out of time.
Key points.
Decide on where you want to work (CPL or ATPL?)
Avoid studying for the exams whilst taking flying training
Look very carefully at the pennies.(FI or IR or both?)
Keep a sharp eye on any time limits for passing exams/ flying courses. (no one wants to do ATPLs twice)
Find and bribe some lucky stars (for job hunting)
The North Sea job market is highly variable and no one can put their hand on their hearts and say jobs will be available in 6 months time, let alone 2 years time.
Good luck and enjoy it.
