Blacking out

[Rowan]

Thanks for the fixes and the update in the Nevada Razbam, good job, but one little thing why am I blacking out at about 33 000 feet, at 25 000 odd ft my vision goes blurry and I don't know how to stop it, apart from dropping back down to a lower altitude of course. I think they call this asphyxia or some such thing. I also noticed the oxygen indicator stays at zero.

 

What am I missing?

Hey Rowan,

 

Can you please give me some more details? Can you send a track file?

 

This would be the hypoxia simulation, which happens when:

 

A) The cockpit pressure is below about 25 kilopascals...is the canopy there, closed, and sealed?

 

B) You've run out of liquid oxygen LOX (which is highly unlikely, as the 5L bottle can last up to 30 hours depending on altitude.)

 

C) You've switched to your emergency supply, which will only last a few minutes depending on altitude, and have exhausted it without realizing it.

 

You say the oxygen indicator stays at zero, do you mean the LOX meter, or the flashing oxygen flow indicator?

Ok here is a track file.

 

Pic 1 shows the indicator I am talking about, not sure if I have identified it as the oxygen meter correctly. Pic 2 is me assuming this has something to do with oxygen or LOX, I have no clue what LOX is, never heard of it before.

This is odd, Rowan. I have no problems when I run your trackfile on my updated OpenAlpha.

 

It seems you are starting with no LOX?

 

If your issue persists, you can disable the oxygen calculations:

 

Navigate to

 

C:\Program Files\Eagle Dynamics\DCS World 2 OpenAlpha\Mods\aircraft\M-2000C\FM\config.lua

 

Scroll all the way to the bottom, and set

 

disable_built_in_oxygen_system = true

Rowan,

 

I have identified the source of the problem, and it has been fixed internally. The issue was in the way the capacities of the oxygen storages are declared...it seems they aren't always declared properly.

 

In this case, a DCS Repair will not help you. Please go straight to editing config.lua as stated above.

 

I apologize for this bug, and thank you very much for your hasty report.

Ok thanks mate, but are you sure about that? Not to question you but as soon as I read your other post my brain sparked, it might be a mod. I was using the NVG mod as temporary measure until the landing lights are fixed but as soon as I disabled that mod the problem went away it seems, got to 50 000 feet or so and no blackout, I tried twice now without that mod, and it seems ok now.

 

I was going to let the modder know his mod is causing a problem, but you will be able to assess that better than I would.

 

But thanks for your help, I appreciate it, and congrats on your module it is very good.

When you're enabling mods like this you have to be careful which files you're replacing

 

If you're replacing files that have been worked at there will be some issues well most defenently be some issues

 

So you ether have to manually edit the new file or wait for the author to fix the mod by him self then post the update

 

It's just how it is

___

In this particular case you're replacing device.lua and device.int.lua files where the files have been worked at and system been declared by putting an old file in it's place you basically removed a part of a code which is needed for system to work

Thank you, it's good to find this won't affect as many people as I had expected.

 

Still, it did lead me to identify and fix a legitimate bug in the code! Thanks for that.

I had the same thing and use the NVG mod, which will come off before I do a repair. When it first happened I thought I had a GPU driver issue as the HUD was the first thing to start to blur. A few alt-tabs back and forth and nothing, then it got worse until I almost blacked out and the dropped 30,000 feet. Awesome modelling Razbam!
