FS2020: The Mixture: Tutorial & Optimal Usage - Back To Basics With MSFS: Part 23

Here's a video that I've intending to make for some time for our Back to Basics Series. Do practice using the Mixture in various aircraft.

Nice video Huddison! 😎 You are correct that most "Real" C-152's didn't come with EGT gauges. I'm sure there are a bunch these days, but nor originally.. haha..
You describe how to set mixture great here!

All the mixture does though, is either add or reduce fuel to the carburetor, to help maintain the optimum Air/Fuel Ratio.
As you've said, at lower altitudes, there is more air (denser) so you need more fuel.
At high altitudes, there is less air (less dense) so you pull out mixture to reduce fuel to carb and maintain that Air/Fuel Ratio and optimum engine performance.

That's why the EGT is helpful.
If you have too much fuel, it actually COOLS the exhaust because not all fuel is burned and the vaporized excess fuel has a cooling effect.
As you lean it out, most fuel is burned so no cooling effect, and the temp goes up.
Same with too lean, EGT goes down, because less fuel produces less energy, thus less heat.

Anyway, Great video, and hope you enjoy the little deep dive as to "Why" it works.. 😎

Hi James,

Great introduction there :)

One useful tool when flying many of the aircraft in the sim equipped with the G1000 NXi, is the lean assist function.

On aircraft equipped with the G1000 NXi, and which have been configured by the developer (including all the stock G1000 aircraft with a mixture control) this function is available by clicking on the Engine tab softkey (1st softkey on the MFD), followed by the Lean tab softkey (2nd softkey), followed by Assist (6th Softkey)

This will allow monitoring of CHT and EGT temperatures, and will show the Delta (difference) in EGT temperature between the peak and the current value (and whether you are rich of peak / lean of peak)

This makes it even easier to find the peak EGT temperature - and is also helpful for setting specific lean of peak / rich of peak mixtures for true optimum power / optimum efficiency settings (possibly something to cover on a more "on to intermediates" level mixture video) 😉

Thanks James. Along with other helpful comments here.
Something I normally let the ai take care of . Ive seen a few videos on here on this subject.But this is by far the easiest to follow . Cheers for another great video mate. 💯👌😊

I removed the clock and replaced it with the EGD gauge right away in the 152 mod. Nice feature. In the G1000, I think you can click engine in get more info for mixture.

[RedRuffinsore]

This was a nice review. Scary looking at the fuel levels while reviewing the EGT gauge. I was afraid you were going to take off with no fuel! Thanks for these review tutorials.

[StrGzr]

When I was ready to address mixture, I immediately sought out your page. Thank you.

[manusavinelli]

Hello ! I'm french and I just saw your video a few minutes ago ! Ah ! your english is so perfect and your explanations so great ! I think I've understood almost all you are talking about ! Thank you ! You're great !

[mikecoffee]

Another Fine educational video Thank You

[Rosenrot]

I fly the pa44 a lot in the sim, quite an easy aircraft to learn things in the sim. Has the egt gauge, and used all the time flying at higher altitudes, twin engines, great fun for us non rl pilots.

[benhalvorson]

I believe the throttle decreased or adds the amount of air going to the engine. The mixture only decreases or adds fuel.

[swailesy]

This explains why my engine cut out and I crashed I was trying to restart trying different methods only to now realise the auto mix set it all the way out

[BacchusPlateau]

I noticed throughout the video you tend to change description between adding air or decreasing fuel by pulling the mixture. Leaning always removes fuel. The air is always there, and is controlled by the throttle.

Think of mixture as a valve for gas.


As always, though, I do appreciate your tutorials. 🙂

*Edited for clarity after watching entire video.

Very interesting. The fuel mixture warning was something I was getting regularly in my fights until i found some tips on your Discord. This further helps though.

One query though.. in the 152 you said optimum was about three-quarters across the gauge but in the 172 it was halfway across so it's different for each aircraft or just dependant on altitude?

[ebenbrittz]

using this video to try and figure out skydiving missions in msfs2024. I see there is an automixture assistance that you can put on. Don't know if this is gonna help someone. Thanks for the video!

[batfink]

Your carb heat was on in cruise, not sure thats right, you would have less power then.

[spares]

Hello, someone now whet the ATR 72 will be available in FS2020? Thanx.

[davidclark]

so in the end you are stuck with the mixture in full out position. same problem i am having. why does it do this?

[Old_BH_Gunner]

Hate to break it to you, but this is all wrong. Mixture clearly is about whether you add just tonic, or tonic and lime juice to your gin.

As someone with 500 hours logged on FS 2020 on my Series X I must admit to spending too little time flying anything other than a jet powered Chariot of Fire.
