The foundation of good flying instruction demands 2 almost completely separate skills sets.
1) Above average flying skills so that you can effectively demonstrate a manoever, and then recognize when you see a skill error and most importantly be able to understand what actions/inactions of the student has caused it.
2) Be able to effectively teach the manoever you have just demonstrated in a way that allows the student to be able to fly the manoever themselves.
The PPL is not rocket science it is set of foundation flying skills which provide the basis for safe flying. You do not have to be a gazillion hour pilot to be a good instructor, but you do have to have the personal discipline to always demonstrate a high standard of personal airmanship and accurate and precise flying. This
must be combined with a genuine desire to put the students interests above your own.
Unfortunately far to much basic flying instruction is carried out by instructors who are only interested in warming the right seat collecting PIC hours until they can get a "real" job
Therefor a PPL instructor who is only interested in passing on his passion for flying to a new generation of pilots, can be extremely effective. I just want to reiterate that there is a huge amount of hard work required for you to achieve your goal of a PPL FI. Every flight instructor I have taught has been shocked by how hard the course was.
