I am 36 and just gained my PPL. I have decided that the way to go for me is to become a career instructor, and I have just started the CPL groundschool course distance learning with GTS in Bournemouth. I intend to build hours at my own pace and do the CPL flight training and eventually the FI course. My intentions would be to instruct at weekends, as I already have a career from Monday to Friday.
I went through 3 or 4 intstructors during my PPL training, all of them young graduates from an ATPL integrated course with their eyes on the airlines and using instruction as a means to hour building.
I think the industry deserves dedicated instructors, especially the PPL student pilot.
Just my thoughts......
