Thanks for all the info.
I've been doing some research and was wondering if this would be possible:
Buy a small plane (like a 172 or similar), start gaining hours with an instructor, get a PPL, then keep flying/learning and take all the other things (ATPL, CPL, etc.) then eventually end up flying for an airline/private jet? How common is this? I always thought you required other qualifications such as degrees in Maths/Physics or similar.. to fly for an airline/etc.
If you buy a very small plane, do the hours still count towards CPL/ATPL, or do you need a bigger ac as you get to he 'higher' licences? Once you have ATPL can you fly for an airline? How common is it for people to buy their own plane right from the start and train with it, is it better? Can fly anywhere in the world with a PPL as long as the ac 'allows' it? Are there any limits when building up hours, so could you theoretically fly 10 hours a day every day until you have enough?
