I know this is an aged topic compared to the fast mover threads now in progress, but the pressurization of the B200 is still a headache and I was wondering if anyone has come up with a fix (because Carenado sure as well won't be)? I've tried dumps, I've tried setting the wheel and then adjusting the rate to 0 so it stays fixed, but the needle still rises and I still hit the maximum (generating a master caution). I'm not sure what to do at this point short of staying below 18000 feet to keep the pressurization happy. How are you guys able to fly at reasonable altitudes without wanting to pull your hair out because the pressurization system is doinked?

In this topic for the B1900 I posted the chart from Beechcraft for setting Cabin versus Pressure altitude. http://forum.avsim.net/topic/432056-cabin-wont-pressurize/page-5#entry2919997

 

Carenado continues to get the graphics on the dial incorrect. In this case the B200 should have a cabin pressure of 6.5 PSID. Based on that you can refer to the chart and see to cruise at Fl250 you need to set a cabin altitude of about 6,000'. We want to set a little less than 6.5 PSID to keep the system off positive pressure relief. Before landing reset it to 500' above your landing airport's pressure altitude. Normally this is done on the descent check.
