losing consciousness

[leafer]

Had to descend to 7000 feet for the effect to disappear. The oxygen was on so it couldn't have been oxygen starvation could it?

[thisisentchris87]

If you weren't pulling any Gs it looks like a lack of oxygen. Try to reproduce it and double check that your using the oxygen controls correctly. Plus I'd make sure your cockpit canopy was fully down.

[Agg]

That looks like the hypoxia effect you get when you go too high without oxygen. Maybe you were running low on oxygen?

[Steel Jaw]

Very cool that it's modelled: switch to 100% oxygen and you're good to go.

Were you flying for a long time (maybe Oxygen supply ran out)?

Was the flow light cycling?

Random failure? (Check caution & warning panel)

[swift]

Loss of consciousness by hypoxia, how cool is that? Regarding to the simulation of physical symptoms, I'm looking forward to the pee effect, and the piddle pack system.

 

[Nightmare]

Cool!....hahahahahah:pilotfly:

[power5]

Is it SOP to turn oxygen on before take off, and then to keep it on? Long missions may need the oxygen, but if its on and not being used while flying low isn't it being wasted? I mean, if a mission takes you 30 minutes to a mountain range and then over the top of the 15k mountain, you could run out before you complete the mission on the other side and still have to get back over the mountain to get home.

The effect was noticeable shortly after I leveled out at around 20000 ft so I had plenty of oxygen. I tried setting 100% pure oxygen but only for a minute with no possitive effect. And as stated, the descend to 7000 feet cured the symptom. In fact, I think it wasn't until I was around 5500 or so feet when the symptom went away completely.

 

Funny that I didn't even realize what was happening during the onset and continued taking screenshots.

 

Canopy should have been fully closed since I used Ctrl+c and no failures set in ME. Weird.

[luza]

had the same thing happen, but switching to 100% oxygen worked..

[leafer]

Perhaps I should have left it on pure oxygen. I'll see if I can duplicate this tomorrow.

[P3CFE]

Was youre cabin pressurization working corectly?

 

If the cabin presure is above 12000 ft, and youre oxygen mask is not working, (delivering o2 under pressure on the face).

You will get hypoxic in real live.

 

Dont know if it is modelled that way in the sim dough.

[MTFDarkEagle]

There is a air source switch somewhere (can't recall where exactly --> above the lightning panel)

[sobek]

You can easily cope with 12000ft without acclimatisation if you have a healthy metabolism and don't put additional strain on your cardiovascular system.

[kylania]

I started to lose at 20,000 the other night. Switched to 100% OXY and all was well.

Sitting down, at 1g, without needing to make any meaningful decisions, ya. But lack of oxygen manifests itself with poor decision making waaaaaaaaaaaaaay before full-blown hypoxia sets in.

 

The difference between survival and being an effective pilot, much less an effective COMBAT pilot, are two separate things.

The current A-10C has transitioned from LOX to OBOGS. As long as you have bleed air you have oxygen. and then 30 mins after the loss of bleed air you still have oxygen. would like to see this modeled someday.

[GGTharos]

... so ... hasn't anyone powered on the bleed air in their A-10C?

[MTFDarkEagle]

I did :)

 

But I haven't been to that altitude yet.. (no hotas YET, if it has arrived: I will go insane :D in 2 days it should arrive :D)

It appears I didn't leave it on long enough the first time around.

Usually you can go up to 15000 without oxy without problem. 15000 feet is the mark if i remember. I know i did some jumps around 14.000 feets (13.000 feets from ground + +- 1200feets above sea) and never felt anything. Of course we only stayed at that alt 20 min max.

And i m asmatic, so suposedly more prone to those effects, but with the adrenal so high it may very well have cancelled any symptom.

In the military at least for us helo guys its something like 10,000 feet for greater than 3 hours, pilots must don oxygen. For operations above 13,000 feet oxygen must be donned by the whole crew and worn for the duration of the flight till below 13,000.

 

As for the game, I believe the hypoxia sets in around 20,000 (very slowly,) so set oxygen to 100% when around 20,000 ft.

 

The effect doesnt go away right away just keep your oxygen at 100% above 20K and you'll slowly watch the darkness fade away.

It happen to me also. I think it may have been a loss of cabin pressure

[nomdeplume]

I started blacking out after being above 20k for a while, turned on the switches that control internal cabin pressure. They're labeled as "No function" in the tooltips but obviously they actually are functional. I think it was the one to the right of the pressure indicator dial that actually made the difference. Didn't change the oxygen level setting at all.

[StrongHarm]

I was an Environmental Systems Technician. The oxygen regulator provides O2 on demand based on a complex series of check valves (and doesn't require power as it does in DCS btw, with all due respect :) ).

 

Scabbers, are you certain they went with OBOGS on the 10C? When I was in, that system was too secret and expensive for high risk aircraft. Good for them if they did though. Liquid oxygen is too dangerous. I had EOD guys look at me like I was nuts when I'd walk past with a LOX bottle venting a cloud of pure oxygen behind me. It sure was fun to soak a rat in LOX and toss it in a huffer exhaust though.. FOOOP.. flaming rodent for 300ft. I also liked soaking a frog till it was a good -350deg, then shattering it on the flight line just before FOD walkdown (everyone lines up to pick up foreign object debris from the flightline). The pieces of frog would form some kind of film over them as they thawed. So they would stay solid and turn grey like rocks...until you picked them up.. then they'd ooze over your hand. Good times.
