spoke with a Great Tech support person in Savanah,. Barry Kessler,. tomorrow I need to take photos of manifold PSI during our flight, and outflow valve position. Plus ground test readings,. Barry wants Manifold PSI readings at 65% HP / 70% HP and 75% HP for each engine, manifold values should remain constant,.

Barry wants to see the integrity of manifold PSI at different phases of flight, outflow valve position etc,.

-during decent, 12th stage air from engine is utilized for cabin pressurization, During climb and cruise, only 7th stage air is required.,
