After 39 years in the helicopter industry (flying), my opinion of what would be an industry "best practice", is not take low time, newly licenced pilots and think they should become qualified flight instructors.
A qualified instructor in my opinion should be able to draw upon years and flight hours, of valuable work experience to teach more than just a basic air exercise.
Mentoring of inexperienced pilots (or maintenence personell) seems to be becoming a lost practice these days.
Using instructing for time building to me, is a poor approach for a good start in this industry.
