Pressurization problem

[Matt Piotrowski]

I did a flight and before cruise the plane starting acting weird and the auto fail light turned on and there's dashes on the pressurization panel. There is a horn going off also. I never had a problem like this before. I have failures turned off.

Hi Matt. This - or something very similar - happened to me a couple of years ago. I discovered I had left a door open

Cheers

commence descent to below 10000.

while descending run the non normal checklist,check bleeds silence horn with button on overhead switch pressurisation to manual and cycle the dump, switch to the alternate source, 

check target altitude and reset if needed.

at or below 10000 ft check doors etc.

If pressurisation ok now climb as needed.

Plan alternate taking into account altitude.

I think I figured out the problem. I looked online and the PMDG website and they said that if your bios can’t keep time you need to change your cmos battery to fix the issue. My bios wasn’t keeping time so I changed my cmos battery and now my pc time is correct. I will do a flight tomorrow to see.
