Is hypoxia simulated in the harrier? (Answer: Yes!)

[Crash *]

As the title says.

 

Flying long time in 40.000 feet with Oxygen off, there is no suffer or blackout for the pilot.

please, can you try it again? Or i missunderstood something? flying in high altitude without oxygen should be enough to get blurry. But there is no hypoxia effect to me.

next time i am in the cockpit i will

Has anyone tested whether there is any effect on the Harrier pilot when flying at high altitude without oxygen?

Hi.

Long since I used the Harrier, but I can recall situations where I started to see grey, blurry, worst, I thought it was me, but went to the oxygen switch, put it to on, and the blurryness disapeared, so I think it is modelled. Same with the F-14. Can't tell for other modulles, and again, many months since I had that issue.

Saludos.

Need to do a proper track file.

Yesterday I flew several minutes between 23000 ft and 30000 ft with oxygen set to off. Nothing happened. But I switched it to off only after reaching 20000 ft.

How long will it take to see problems? I guess, will try with the switch off from startup next time.

@Crash * What was your flight? Only putting the oxygen switch to off? Or also putting the canopy lever in the unpressurized position?

 

As long as as the cockpit is pressurized, the cabin pressure will help a lot. Will try next time, taking of with unpressurized cabin and oxygen off.

Thanks @Fri13 for the reminder. Always forget about the pressurized cockpit in the non warbird planes.

The cockpit is pressurised, so you should check your cockpit altitude.

 

Yes very high like 40 000ft I think the pilot should need the 0² mask. But at altitudes like 20 000ft or 30 000ft, probably not that much.
You can flind some videos of pilots having fun in flight and even removing the mask or helmet during cruise...

During long missions they would also have to remove the mask to eat or drink.

 

PS: cross posting, sorry

The canopy lever was closed. Will test it the other way today.

when i tried this i was at ~40-45k feet and i left the canopy open for take off because i wanted to try out what happened.

it took like 10 seconds to see effects and after 30-60 seconds i was totally blacked out until i crashed on the ground / used the ejection seat

[gulredrel]

Works as intended. Oxygen switch off, no problems as long as cabin is pressurized.

Seconds after dumping cabin pressure with the switch on ECS control panel on right console, the vision gets blurry.

Putting oxygen switch to on position, even with ambient outside air pressure at 30000 ft, pilot regains consciousness. 

 

 

Tested in current OB 2.7.1.7139

well done @gulredrel.

Thanks!
