Rojer was old school, he came from a single seat environment then the M16, Rojer knows rotor management and I am not at all surprised he taught it extensivly, he knows it's value.
you mention "the latest training manuals".. this suggests that things have changed and I hope improved. I wonder if the manufacturer has also decided to change the pilots notes to match the new procedure ? out of interest what gyro do you fly ?, is it fitted with a rotor tach and powerful pre rotator ? can you fling start the blades and bring them up to speed if the pre-rotator fails? if either fail is it a no fly situation ?
