Your post on 'real time mental models' was I am afraid too obtuse to be understood , certainly by me.
Your post on mentoring really means flying with more experienced pilots, and that is always a good idea.
I am assuming you are talking about qualified PPL holders who should be able to learn from both the good flying of their mentor and be able to silently note the poorer points of their mentor's performance,while starting out on the lifetime task of adding new skills and confidence to their flying,which is precisely the point at which the PPL course is intended to pass the PPL holder on to the rest of their flying life.
