Yes, I had the oxygen lever on and no mod fix.

Somehow fixed after 1.3.24.0, though the oxygen depletion message still pops on random flights.

Sim Update 1 Beta (1.3.24.0) Release Notes - February 28, 2025 - Sim Update 1 Beta | MSFS 2024 / Beta News - Microsoft Flight Simulator Forums

According SU1 Patch :

• EPS Does not power oxygen, ESIS (standby attitude), or Pressurization system. It should power all three.
• Oxygen system is at zero at all times. (likely causing issues in career).
• Hypoxia in career mode due to oxygen / Pressurization / ECS not modeled correctly.

But still occure in SU1 final version

[wcc96387]

Ok, Just tried a flight WITHOUT the Pressurization fix and failed due to hypoxia. So the Fix is what has been allowing me to fly normally.

[COLxSANDERS3209]

Installed Sim Update 1 and this is still not fixed, happened at FL240 about 30 mins into cruise.

[EngineerZed]

Extremely disappointed that after waiting for a fix and it seemingly being addressed in SU1 release notes that it’s not fixed! Cabin pressure shows altitude below 10,000 feet and the oxygen lever is on! Mission still fails due to hypoxia!

don’t worry, because important issues are being addressed:

• Added profanity check on Callsign and FlightNumber in aircraft configurator

• Aircraft Battery does not drain while generators are disabled.
• Upper and Copilot display units turn on even when on battery only power. They should not.
• Auto throttle does not respect ITT limits and causes engine damage in career mode.
• Flashing amps and battery caution CAS/EIS lower DU during normal start up.

• Oxygen system is at zero at all times. (likely causing issues in career).
• Hypoxia in career mode due to oxygen / Pressurization / ECS not modeled correctly.
• Strange Ice visual on props.
• Rain animation missing from the cockpit of the PC-12.
• Exhaust effects are overly exaggerated.
• VOR needle color is incorrect.

i assume the wording of changelog v1.0.8, which implies that they ADDED these bugs in the patch, is unintentional.

[JeremyGolf70]

My mission has failed when cruising at FL290 for about 30 minutes with PC-12 in freelancer mode. SU1 has been installed and oxygen switches, cabin pressure switches are checked on operating position.

[wcc96387]

Did you install the pressurization fix posted a little while back? That fixed it for me. Other than that I don’t believe SU1 actually fixed the issue

[lanceruss]

Let me guess. The patch did fix nothing.

[madeinblue]

It’s still written in the bug list, will be fixed on SU2, don’t except it before

[JOEDANCEN]

still no fix. Should be easy by Asobo to fix. Just disable the hypoxia warnings.
Patch did not work

Edit: patch did work. Had the wromg community folder

[ESpartan5271]

The plane is totally broken! performance, oxygen, auto throttle, avionics, no visible cargo… it´s a shame!

The issue is simple the fix, is only PC-12NGX have this issue …, my mod proves it

@SeedyL3205 You can Escalade my solution ?

PC12 Pressurization/Oxygen System Broken

A make some test, is easy to fix this issue with one line to change in System.cfg, THANK to Modular SimObject System and Dev Career Tool The issue is the Press Cabin Goal is too high : 28 497 FT In System CFG PC-12 use Pressurization setting (BTW is only aircraft use this setting ..) Default Setting [PRESSURIZATION] design_cabin_pressure = 7.5 max_pressure_differential = 5.75 My setting use for fix this issue [PRESSURIZATION] design_cabin_pressure = 10.8 max_pressure_differential = 5.…

[Halliday42]

The Sim Update 1 should have fixed it, according to the release notes:

• Oxygen system is at zero at all times. (likely causing issues in career).
• Hypoxia in career mode due to oxygen / Pressurization / ECS not modeled correctly.

However, I can also confirm the bug wasn’t fixed, I still received the oxygen level warning screen during a mission in career mode at FL240.

[JOEDANCEN]

Did you have the update? Autothrottle is fixed. Oxygen also with third party patch. No ITT with take off and for vr the autopilot is aligned better.

Downside; to much exposure, landinggear bug, unstable aircraft on the ground activate crash, so one step forward 2 steps back

[iKeepOnTruckin]

It is working for me, I set cruise alt in the flight computer (not autopilot) before I took off. Not sure if that makes a difference.
