Hi,

I would like first to thank you for the great job of the b767-300, it is a wonderful aircraft, however there is a strange problem that i face:

In the overhead panel, the cabin altitude gauge, this gauge (the middle gauge in the pressurization panel) if the panel knob is set to Auto 1 or Auto 2 modes, it should not exceed 6000 feet even if the aircraft is on fl370, but i noticed that the gauge always indicates half the cabin altitude, that means that if the aircraft is fl200, the gauge reads 10000, and if the aircraft is fl300, the gauge reads 15000.

I think that was a fault as the cabin pressure altitude should not exceed 10000 or a warning and emergency would take place. When i reached fl380, the cabin altitude gauge read 19000 feet!! of course that's very unrealistic. If the cabin pressure reached that extent passengers would have died.

Please help me to fix that serious fault.

best regards

Jim

I did a flight in the Qantas 767-300 GE and the Cabin Alt was at 20000+ when I was flying at FL390. :(

Hmm, looks like we're all dead from hypoxia  :). It seems to be a major bug here.

Not at all. I'm practicing for my planned ascent of Mt Everest without carrying oxygen bottles! It has been done before.

For real? Wow, that's extreme.

What about:

Thanks for your reply. Yes it is a major bug. Isn't there any fix for that?! :'(

Sorry Matt. I was being sarcastic. I have a sick sense of humour.

I saw the Air Crash Investigation episode on the Helios crash, very tragic (but then all air disasters are).
As a former avid golf player and fan, I was saddened by the loss of Payne Stewart. I can't believe it's been that long. :'(

Didn't catch that (after all that House episodes!).

I noticed this when I first installed it and forgot to submit a ticket as it was only a minor niggle.
Has anyone tried to set the pressure manually? I have a few times at FL390 and the best I can get it down to is ~16,000ft.

There has been a few nasty accidents with pressure failures, there was a Beechcraft King Air 350 over here in Western Australia that flew for 5hrs up to Queensland before it was seen to go missing. All on board fell asleep and it stayed on course until she was out of fuel. IIRC they were cruising at FL250.
EDIT: It was a Super King Air 200. https://www.atsb.gov.au/publications/investigation_reports/2000/AAIR/aair200003771.aspx

Some really weird things can happen wrt to air pressure, I have spent some extensive time in hyperbaric chambers and have suffered a couple of oxygen fits. So it works both ways you can also have too much pressure/oxygen.
The scary part is that you don't feel it happening, one minute all is ok, next thing you know you're unconcious. When you wake up you know something has happened but have no idea what.
