[CHK] Oxygen configuration

[wired521]

Hey guys quick question regarding oxygen configuration. My understanding is the JF-17 pit is pressurized; does the oxygen valve need to be opened at all times or only under certain circumstances?

I normally leave it open and verify the blink light, but figured I'd test to see what would happen if I closed it altitude (FL32). I didn't have any issues after ~15minutes.... until I also unsealed the canopy  . Then, I started noticing the blurred vision effect... although I'm not sure if this was related to the "icing on the cake" temperature modelling.

Can anyone confirm if the oxygen valve is supposed to be open at all times? If so... any thoughts on why there wasn't a problem at altitude when I closed it (bug?)? I tried looking at the manual but it's still very basic... at lease the one that ships in the Docs folder.

Thanks!

The oxygen valve must be opened the entire time when the canopy is closed. The blurred vision effect represents pilot oxygen starvation, that it occurred when you have unsealed the canopy is a coincidence. It doesn't occur immediately because there's still some oxygen in the air, but overtime it does show. And yes, this effect is present throughout DCS in every module.

Not every module, some seem to have it in un implemented. I don’t think MiG-19 pilot suffers from oxygen issues at all.

For JF-17, effect also appears faster if you pull G

@WarbossPetross So I just did an entire sortie over FL20 (most of which was FL30 or above for endurance) without the oxygen valve open, no hypoxia effects at all. I don't think that it was coincidental that depressurizing caused this before. 

Perhaps something isn't working as intended atm?

 

FWIW I've ran into this plenty in the F14 if I miss the oxygen switch on startup  .

Bruh I once managed to choke myself in MiG-15 right on approach for landing because I accidentally CLOSED a valve in the oxygen system that's normally open. Maybe depressurization is rendered in the same blurry way even though it's a different condition and that, in fact, is what OP has experienced. Then there's a Hog tutorial by Ralfidude where he demonstrates the hypoxia effect. I guess that's where ED needs to implement a uniform framework for oxygen, pressure and stuff and 3d-party developers need to stick to it.

Yes I’m not all denying OPs or anyone else experiences, just saying in specific reference to the statement that all modules have it, that this statement is slightly incorrect when it comes to 3rd party modules 

[wired521]

So current behavior appears to be incorrect, at least for me. Anyone else seeing this?

Yes, but I get hypoxia effect as soon as I pull G

if you stay below 15000 ft, and you don't have on oxygen, you should be okay, as I believe that's where they decided that hypobaric hypoxia sets in. If you pull Gs and you don't have your G suit plugged in, then you will experience that same effect, but it should just be blacking out, because all the blood will rush to your feet instead of being pushed up by the G suit.

MiG-19's pilot suffers from hypoxia as well. Only problem being, from what I was able to gather, that oxygen valve is in the open position at cold start (contrary to manual/start up procedure). So it is possible to leave it out and don't spot the difference. I got blur, tunnel vision and started to black out because of that.

Hmm, must’ve been added since I checked last, admittedly a long time ago

Yup. I found this out by trial and error.

Hey @uboats do you need me to file a bug report for this (with a track file)? Seems like others are seeing this behavior as well.
