When forced to 30,000 ft. I am getting a cabin altitude warning. If I don’t descend I will get use oxygen warning. I have been careful about the checklists but must be missing something. Any help from those more knowledgeable will be greatly appreciated.
The pressurization system is not implemented very well,but the remedy is to climb slowly. Not faster than 2000 ft/min or so. At around 170kt.
Monitor the press diff indications to see if it can keep up and lower the climb rate if necessary.
Above FL250 reduce rate of climb to 1300-1500 ‘/min
If altitude warning starts push on ALT button to stabilize TBM . After 20 to 30 seconds warning stop. Then continue your climb.
In true live at FL310 pressurisation cabin is 9350’ maximum
I think this was a bug that showed up in the last sim update, I’ve seen other posts with the same problem.

You’ve probably out-climbed the pressurisation system. Next time it happens, make sure the bleed switch is on and watch the gauges. You’ll see the virtual climb rate in green, probably about 500fpm. If it’s a positive rate, its working. When the cabin altitude falls below 10,000 the alarm will stop.
Thanks for the replies. I know more now than I did yesterday. It is those of you who make up this community that make MSFS so enjoyable. I have other issues and questions but will save those for another thread.

Be aware that in real life you can’t “out-climb” the pressurization system. Should you climb significantly faster than the cabin is climbing, the cabin will reach max. differential pressure. Usually the safety valve opens to reduce differential pressure. This could cause a serie of pressure spikes and is uncomfortable for passengers, it would however NOT cause the cabin to climb above the required cabin altitude! If there are no system failures and you are not exceeding maximum certified altitude, you should not get cabin pressure warnings.

The cabin pressure switch should be flipped to max when this happens, but I did that and it has no effect.
how do you adjust cabin pressure settings in the plane?
It’s automatic.
i found the controls. still need the ability to dump pressure and enable it, etc. its in front behind the yoke
