Inaccurate Mixture Behaviour on Turbocharged Piston Engines
-
This issue was raised at the main forum, but has definitely been unnoticed by many (frankly, many might not even understand what's this about). Please, vote to raise it up. We all will benefit from the corrections.

Confirming that I don't understand anything about it, but a lot of people nodded in agreement and there's even charts in multiple colors, and that's good enough for me.
It doesn't seem to be getting much traction, maybe because not too many people fly turbocharged aircraft or because they don't understand the significance (I've been avoiding flying the Turbo Arrows because I'm still learning the Warrior, and as soon as he said turboprop and turbocharged are not the same he lost me), but maybe JF can put some weight behind it to get Asobo to fix it.

@jmarkows said in Inaccurate Mixture Behaviour on Turbocharged Piston Engines:
turboprop and turbocharged are not the same
This seems to confuse a lot of people but it's actually really simple.
Turboprop means a prop driven by a turbine engine - like in a Dash-8 or a TBM. The engine is a turbine engine just just spinning parts (for the most part) - the same as a turbofan engine which you find in airliners like the 737 but instead of powering a big fan at the front it has a propeller. There is also another type that works in a similar way - a turbojet engine - which has no prop or fan at the front and is just the turbine part, but those are very inefficient.
Turbocharged engines are reciprocating piston engines (just like a car engine), powered by pistons moving back and forward to compress the air fuel mixture and to turn the driveshaft when the mixture is ignited. The only difference between a normally aspirated piston engine and a turbocharged one is that the turbocharged engine has a turbine in the exhaust pipe which gets spun up from the exhaust pressure, and that is used to push more air into the intake. The result of that is even at high altitudes a turbocharged engine can have the same (or even higher depending on the type) air pressure in the intake manifold that it would normally have at sea level which greatly improves high altitude performance.
One way to tell the difference between the two is by listening to them start up. A turboprop engine makes a whirring sound - consistently getting higher pitched and louder - and takes quite a while to get up to speed (the turbines in those things spin up to insane RPMs!). A piston engine on the other hand will sputter for a few seconds as the starter is getting it going then will quickly start running smoothly

I've also posted about this in the turbo arrow part of the forums. I've done the fix listed in the thread you post and it works, other than the graphical issue of the mixture automatically moving. Makes it much more realistic. The community manger for MSFS2020 came back saying they were not looking into it that much as they didn't have a default turbocharged aircraft...
Well, I'm going to be replying... they do now with the p51's and reno race packs....
