Hi,To whomever else has found the cabin pressure bug (reading too high of an altitude) in addition to myself, I've found that this problem only occurs when flying a model with a clickable VC and the 800/900 update installed. If I fly with a 2D panel only model the problem is not there. Therefore, I would assume that this bug was introduced with the clickable cockpit VC models in the 800/900 update.The 1.3 version of 737-700 (without a clickable VC) works perfectly in regard to cabin pressure altitude readings.In addition, I've noticed that when I fly a 2D cockpit model only that the cabin pressure reads zero before takeoff even at above sea level altitudes whereas the clickable VC model pressure readings indicate the sea level surface elevation. I would guess that there is a perhaps a calibration issue between the two different models but I cannot be sure.

Ok, here's the latest I've found -If flying a clickable VC cockpit model, you can comment out the pressurization gauge for the VC in the appropiate aircraft panel.cfg file and your 2D overhead pressurization gauge will default out to a initial sea level elevation (0 ft) irregardless of your true SL altitude. The end result is that you will get a comfortable 5,000 ft cabin at FL370 or so, rather than a 12,000 ft cabin if you don't comment out the VC pressurization gauge. As far as the pressure readouts go though, you'd essentially be pressurizing the aircraft to sea level altitude before takeoff like a military fighter jet. Chew gum and yawn a lot :) For whatever reason there is a calibration issue here someplace.

Wow Ms. Dianne, you've really seemed to narrow down this problem. I will try your VC cockpit mod and see if I get the same results.Isn't it wonderful how PMDG doesn't give ya one iota of support for all the trouble you've gone to over this issue? :)
