I'm wonder if you can help me. I'm currently cruising at 15,000ft and I have a red master warning light that reads 'cab diff press'. In the cabin press box of the G1000, ALT FT reads '-200' and is green and the DIFF PSI reads '6.5' and is flashing red.
How do you pressurise this aircraft? Where is the pressurisation knob?
Any help would be appreciated.
Many thanks,
Dafydd Rees :D
