Flight training procedures should be 100% in accordance with the POH. An important part of all training, but especially, advanced training is inculcating students with the importance of understanding all of the aircraft systems and knowing what the expected performance should be for every phase of flight.
The only way this can be achieved is by integrating the POH into every lessons.
With respect to piston twins and charter flying I have had to beat out the stupid " flight schoolism " from numerous new hires. Why can't the school just teach it the right way from the beginning ?
