January 13, 201412 yr I cannot get the cabin to pressurize... regardless of what I do with the pressurization knob. Bleed air is on and environ set to auto.. P3Dv2...
January 13, 201412 yr I am using the 1900 in FSX and I am having problems with the system pressurizing. I have flown it for just a few hours and still doing shake out. I thought the first flight it worked just fine but the last flight went to 11,000 ft and pressure remained at zero.

I sent a support ticket regarding the pressurization bug.
January 15, 201412 yr Not sure it's a bug myself. I think if you have environmental bleeds on and target cabin alt set appropriately for your intended cruise level it will behave correctly. That said, I did have to use the dump switch once to get the differential pressure back to within limits, but that may have been pilot error. Luckily they don't simulate the resulting structural failure :lol: signal_runner PPL FSX (SP2), Active Sky Next,REX, Thrustmaster Warthog

I have not seen EXCESS PRESS DIF Warning light installed before, must be an optional thing or something they applied to later airplanes.
January 17, 201412 yr Author I have the bleeds on and the cabin alt set to say, FL210 if that's what I'm flying at. The short needle still goes into the red.
January 19, 201412 yr Yep, I noticed that the first flight I did with the 1900. I sent a support ticket regarding the pressurization bug. Did they reply to you yet ... confirming if a problem exists / or pilot error? Best Regards, Vaughan Martell PP-ASEL KDTW
January 19, 201412 yr I have the bleeds on and the cabin alt set to say, FL210 if that's what I'm flying at. The short needle still goes into the red. You need to set cabin altitude to 1,000' above your cruise altitude. So if you are going to fly at FL210 you set the cabin to FL220. This prevents the system from riding positive pressure relief and makes for happier passengers. On descent you reset the cabin so that the cabin side is 500' above the pressure altitude of the arrival airfield. i.e. at Colorado Springs on a 29.92 dayI would dial the cabin side up to about 6,700' where as at Key West I would set the cabin altimeter to 500'. This allows the cabin to depressurize prior to touchdown so you don't get that whoosh sound on touchdown (the WOW switch opening the safety valve.) When your cruise altitude is below the minimum altitude on the cruise side of the scale you just set 500' above your departure or arrival airport, whatever is higher. i.e. If I am taking off from Key West and flying to Miami and only climbing to 12,000' I would just set my cabin to 500'. I have had no problems with the Carenado pressurization system when used IAW real world aircraft procedures. Must be something you are not doing correctly.
January 19, 201412 yr Author Ken, thanks for the response! I'm sure it is my error. I am pretty sure I'm setting it correctly but without photos showing how the knob is supposed to be set (since the window for visible area is so large and there are no arrows or anything indicating where it is supposed to be set) I'm having difficulty. I'm also having difficulty finding any information on the internet as to the proper way to actually set the knob. My search continues! lol
January 19, 201412 yr Author See, like right now I'm flying at FL190. If you look at the window on the dial, it has two sides, the left side of the dial is at FL200. The cabin stopped climbing at 10k and I get a CABIN DIFF HI annunciation on the panel.
January 20, 201412 yr The top side is your aircraft altitude and the bottom side is your cabin altitude. On the real aircraft there is a window with a lubber line in the center of the display. Without the window and lubber line just set the center of the opening to your cruise altitude +1000 feet. The other part of the pressurization system is the two gauges behind the power quadrant. They should tell you what the pressurization is doing. I am more interested in if the cabin differential is above 5.0 (the small needle) as opposed to the light. Cabin dif should never go above 5.0 even if you set the cabin controller in correctly due to positive pressure relief built into the system. When I get a chance I will try to replicate your flight at FL190 and see if the same thing happens. If so it is a bug and needs to be reported to Carenado.

I had to set cruise alt significantly higher than my altitude (16,000') to get differential pressure in line. Joe Lorenc
January 21, 201412 yr Author http://puu.sh/6tpJj.jpg one more photo... this is in P3D v2, but it does the same in FSX. Cabin alt/FL dial is set same as before and as you can see, the cabin is no longer climbing. You can't see it, but the diff needle is almost at max; it's under the black back end of the longer needle.
