I enjoy flying the Baron but am disappointed that moving the mixture lever at altitude makes no difference to engine performance or EGT gauges.
Please simulate this as it is a critical component to realistic flight in certain aircraft.

Mixture has minimal effect on Standard Edition planes. On the higher editions, it has no effect at all outside of being a fuel cut off to turn off the engine. Shameful, really, that we pay extra for “Premium” and “Deluxe” and instead get half-assed planes.

Mixture seems to work on the C 172 steam gauge (see Squirrel’s video). I tried the Baron for a community multiplayer event and it was hopelessly underpowered, seems the modelling is nerfed at the moment. Other people have commented that they cannot get near the stated airspeed.

If you visit the high altitude airports in Napal you’ll find that the Baron really struggles to gain altitude on 100% mixture. I took off from an airport and nearly crashed because I could barely get off the ground and didn’t know why. I couldn’t climb any higher than about 500ft AGL. I reduced the mixture and was easily able to climb another two thousand feet. Mixture has a big influence up in the cold mountains.
I have no idea how accurate the simulation is though. I’m just saying that something is definitely simulated.
I can agree that something seems wrong with the Barons power though. I couldn’t get it passed about 80% of it’s stated top speed when I last flew it. It wasn’t always that way. It started happening after they made tweaks in the last patch. I filed a bug report on that one already.
I’ll try higher elevations and see how it handles. My last flight was at 7,500’ and in the cruise moving the Fuel lever made no difference to the engine performance or EGT gauges.
The steam gauge 172 is an outlier. Likely because it’s the same plane as the G1000 version, only with a different panel. Even then, mixture has a pretty minimal effect compared to what it should have.
The Carenado planes have better mixture than any of the MS planes, but I suspect they’re also limited by the core of the sim that doesn’t really model mixture properly.

Just took off from Telluride a high altitude airport and had no issues climbing out with full mixture. Note the effect on engine performance and CHT in the following two shots while at altitude. First pic mixture lean Second pic mixture rich.
Don’t forget that the Baron in this sim is turbo charged and thus produces mean sea-level atmospheric pressure to a much higher altitude than a naturally aspirated engine such as in the Cessna 172 or the G36 Bonanza in the sim, which starts to reduce power almost immediately after take off. As a result, the mixture isn’t used the same because the manifold pressure remains high. Some POH’s for turbo or supercharged aircraft state that you can use the mixture to run leaner in some cases to save fuel but I’m not sure about the POH’s recommendation for the Baron, anyone know off hand?
EDIT: pwmacbert below pointed out that the Baron in the sim is most likely not the turbo charged version and after looking into it, I believe that I agree with him. Ugh, I hate it when I’m wrong…

It seems to work fine on the X cub. Not sure how it compares to real life but do see the a difference at altitude
Just performing a flight now. Climbed up to 20,000’. Tested the effect of the Prop lever at 5,000’, 10,000’, 15,000, 18,000 and 20,000’. No change in power or CHT.
Let’s face it. It simply isn’t modeled.
Automixture turned off in options?
No way. All assists are disabled. Sim set to hardest level.
test the 152/172. You’ll find it’s modeled there.
Haven’t tested the Baron myself extensively, so might be an issue with that specific plane if it works for you in the 152/172.
I’m pretty sure it’s a standard G58 and not the 58TC which, I believe, hasn’t been sold for a few years now.

Yeah, by default it’s definitely naturally aspirated, not turbocharged. Try and hold 23"MP above ~7,000ft, and you’ll find it can’t.
Saying that, despite the supposed mixture improvements of late, it is still very poorly simulated.

I know you’ve already probably checked this, but a buddy of mine was having a similar problem, and it simply turned out that he had “auto mixture” set in the assistance options. You’ve probably already turned that off, but worth checking to make sure.
Oh, I thought for some reason that it was supposed to be the turbo version. I will have to look again.

I can guarantee that’s not the case with the Baron. Mixture does nothing. THe only thing is does is cut off your engines if you lean it completely.
“Premium Deluxe” planes are shamefully incomplete.

@pwmacbert I looked into it and I believe I was wrong. I edited my original post. Thanks

No worries.
