Returning to the OP's Question
Think of how many exams you do for you ATPL's. 14 in total. For example Met. You would have a solid foundation in Met. You could go on to study further in Meterology and go work as a weather analyst. Human Factors/Performance, is there any reason why you could not do a little more study and become a consultant in Human Limitations/Performance in the area of performance sports?Aircraft Technical - study a little further and you could look at becoming a aircraft mechanic/vehicle mechanic etc.As a response to your original question, I would suggest that you have a good foundation in many practicle areas, which with a little further study/education/qualification, you could very easily slip into another industry.
