February 28, 200719 yr Hello,I have noticed that there is a problem with the cabin altitudeindication and the pressure differential indicator.While at FL360, the cabin altitude is around 14,000ft andthe diff press is around 4psi. Both packs are in auto, bothengine bleeds are on. Duct pressure is also normal.Cabin altitude should never exceed 8000 if everything is workingcorrectly. Also, the diff press should be higher. And nocabin altitude warning horn even though the cabin alt showswell above 10,000ft. If I go to manual pressurization,I can move the outflow valve from full open to full closedwith no movement of either the cabin alt or press diff needles.I have this with the 600/700 and 800/900. Does anybody knowif there is a way to fix this?Thanks,Adam
February 28, 200719 yr No fix. I think the problem is taking off from high altitude locations (KDEN or KABQ for example). The simulation treats the mile-high field elevation as if it were sea level and doesn't kick-in cabin pressure until much later than it should. PMDG has written on many occasions that they are not fixing minor bugs (there are some more major than this one). Dan Downs KCRP
