the "de facto" limiting altitude

Post by MarcE »

Hi all,

I am currently flying the Bonanza from Northern England to Iceland. I am at 12000ft, full throttle gives me an MP of 19'' so carrying me +2 I could easily go higher.

Also we have other airplanes like the C182 or the Comanche that are still far from home at that altitude, they can easily hit 16 or 18000ft. Are we still limited to around 12000ft due to hypoxia although no oxygen is simulated?

Altitude is range in case of an engine problem and atm I am coming closer to a cloud field that doesn't look like a dry and calm experience.. So I basically can't go higher because of the hypoxia thing (nobody would do that trip without oxygen) and I can't go down into warmer air because I'd lose that bit of safety and I can't fly through the clouds because of icing?

Yeah, I'll decend to warmer altitudes but climbing would be the actually better choice (in reality)

Cheers,
Marc

Climbing might be a better choice, but at higher altitudes you tend to have much stronger winds aloft. You also tend to lose cruise performance above 7,000 feet in naturally aspirated engines.

You might have better endurance, but not necessarily better range due too many factors. In my experience going very high has usually been a wash unless you have some very good tailwinds. Tailwinds can still slow your progress a fair amount unless they are well into your rear arc. The slower you get, the more you have to crab into the wind and the less benefit you obtain.

An additional oxygen system completed with goggles and a low temp suit would be nice for the GA range.

As of now you are limited by hypoxia. The effects aren’t instant so if you want to push it in the sim listen for heavy breathing and then start descending or set autopilot to descend

Is hypoxia modeled in the Comanche / 182 / Cherokee? I've yet to be affected.

OFF Topic :

Talking about hypoxia, I just noticed you have the very computer spec that I have been considering moving up to from an i7 2600 @4.3GHz (GTX1080) With my spec I have to fly in good weather / low traffic to avoid stuttering.

Yes it is. I once lost my Comanche flying over 15 000 ft for too long.
It takes only one time but then you never make the mistake again :mrgreen:
