Pressure Danger Level

[Rune]

Hi there !

First I'd like to thank Dan and the crew for making this marvalous program. I just bought it, because I think it's the best add-on there is these
days, for FS.

Currently, I'm flying from EBBR (in my home country Belgium ) to Gran Canaria in a 747-400.
I'm increasing my altitude to FL180, but at 12000ft I get the warning: "Pressure Danger Level".

Can somebody explain it to me, what it means, and what I have to do ?? (Probably change the altimeter pressure, but to what value ??)
Thanks already !

That's an issue with the payload model. You need to edit it in the payload editor, this can be found in Start/All
Programs/FSPassengers/Tools/Payload Editor. You need to look at the box that says not pressurised and uncheck this box then save the
payload model.

It can be fixed by doing what John recommended, and simply means that your current aircraft model is unpressurized.
