CFI pay
Everyone is right about "not making much" thru flight schools. I started freelancing right off the bat and charged $25/hr until I got some experience. I then went to $35/hr, flight or ground. I recently got my Master CFI designation thru NAFI and my ATP and now charge $45/hr, flight or ground.
Yes, you will have to find students, but I find doctors, lawyers, and other professionals that are financially able to train consistently and this helps keep bread on the table.
You will need to build a reputation, network, and DEFINITELY be selective with your student base if you want steady income. I do interview potential students and if I get a "feel" that they will be less than consistent, then I send them to the local flight schools! No offense......
There is a good book out there titled "The Savi CFI". It is a great book and will give you good ideas. You can also find a "niche" and specialize in that. I am personally getting away from primary students and doing BFR's, IPC's, and organized ground schools and seminars.
Like I said, I charge $45/hr flight AND ground and I am turning students away! Be professional, continue to learn and study, and charge what you think that your time, liability, and quality of instruction are worth. If someone doesn't want to pay for quality training, then I don't want them as a student.
I hope this helps. Good luck!
