Oxygen question
-
The Duke is a pressurized plane, so the turbine is keeping a fresh supply of oxygen in the cockpit, right? I don’t need the on-demand oxygen unless something happens to the pressurization system, right? So I have been monitoring the tablet CABIN page for the Oximeter to make sure none is needed and I am leaving the on-demand O2 off during flight.
Ok I did try it once and with 6 occupants at 19,000 feet, I ran out of oxygen pretty quickly, so I’m hoping that I’m right that it’s just for emergencies.

Yes, normally you don't need supplemental oxygen if the pressurization is able to keep the inside pressure equivalent to altitude of 10k feet or below. So you may need it only in case of pressurization failure or when you really need to fly higher than the pressurization is able to keep up, like around 30k :)

@Pondimus This doesn't sound right. Would you mind explaining what you mean? I think you might be closing the wrong valves for increased heating.

My issue is I have a 3 hour flight at 26,000 to clear the mountains and my Blood Ox drops to 89 in less than 30 minutes into the flight, so I use Oxy and it runs out quickly with 4 people on board

@Black-Square I've been closing the Intercooler Shutoff Valves. When left open, the heater can't maintain a normal temperature with the very cold air at high altitudes. I've tried shutting them only partially, to let as much fresh air in as I can, but still need to supplement with the onboard O2.
Am I doing it all wrong? That's usually how I do things in MSFS. The wrong way! =P
