Cabin pressure question

Recommended Posts

I could use some help with the pressurization system. I set the take off and landing altitudes but I don't know what else needs to be done. I always get the "auto fail" light, but no warning buzzer and as far as I can tell the cabin is being pressurized. A step-by-step run through would be much appreciated. This is a great panel. Congratulations on a remarkable achievement!Sidney Schwartz KPDX

Thanks for the info. Is it permitted to take off with engine air bleed open, or should only apu air bleed be on until after take off?Sidney Schwartz KPDX

normal take-off is with engine bleeds on for A/C.only is you REALLY need the extra power, you use the APU bleed for A/Cbut just gives you a MTOW 3% higher than normal take-off.
