Well the latest brief I used on PP was teaching formation, to put this on a White or Black board as effectively I would have needed to draw in the aircraft, rub it out and redraw it half a dozen times, all this drawing time spent facing the board not the Student, using the PP I had a much more professional looking presentation that flowed better because I was facing the student 99% of the time and took less time giving
more time for student participation and Q&As.
