NATOPS1 Posted March 7, 2012 Share Posted March 7, 2012 Some say we reduce the manifold air pressure PSI to less than 45 to allow the engine bleed air regulator valve to "open" (thinks the manifold air pressure is less than 50 PSI) And some say it is so the starter control valve can open (against less pressure)... I make no claim to either. I know our book says if you get NO propeller rotation to reduce the air pressure to less than 45 PSI and try to restart... I know the manifold pressure will be less than "50 PSI" but I also know the starter control valve is subjected to "less" air pressure.... Thoughts? References????
