Cessna 400. Why when almost max throttle it gets red?

So im flying the cessna 400. And im not even maxing the throttle, yet it blinks red at the speed/engine meter. Why?
And is it something im missing to do?

The first barometer is half way, but RPM is max?

Moved to User Support Hub > Aircraft & Systems that is more appropriate for community support.

Are you reducing the propeller RPM via the prop lever?

I tried it now. It helped abit actually. But i cant figure out how to set the engine barometer? Im playing on Xbox. Is it something with mixture?

It would possibly help you to understand how a Constant Speed Propeller works.

The throttle isn’t directly connected to how fast the propeller is going to spin.

The pilot sets the appropriate RPM for the propeller for the given conditions and engine operating restrictions via the propeller pitch lever.

The throttle is going to apply more power to the engine and allow the propeller to pull the aircraft through the air, but the propeller RPM, in general, isn’t going to increase/decrease — unless you move the propeller lever.

Mixture is, generally, not something you need to concern yourself with until you are above 3000’ (1000 meters).

Above that altitude the mixture will need to be leaned to compensate for the air that gets ever less dense as you climb higher and higher.

In reality, a pilot needs to have an understanding of how the mixture can negatively affect an engine, so that they do not cause a catastrophic engine failure due to detonation, foul spark plugs, waste fuel, etc. In the sim you aren’t going to do any harm (unless you have a 3rd party aircraft that models failures).

Usually a tachometer will have a green band for safe operating RPM and the Manifold Pressure gauge may also have something like that, if it doesn’t try adjusting the throttle as you fly straight and level to see it’s affect on the speed of the aircraft, so you can understand what it is doing when you have it at various settings.

Thanks alot! Yeah the courses on the sim (which is understandable) didnt explain all of this. Thanks alot! This helps alot.

So now ATC asked me to climb to 16.000 feet. What would an appropriate mixture be at? I have set it to 100%? I hope you realize such a noob i am about this and im trying to learn. So sorry for the stupid questions.

Don’t apologize. We all have to start from zero.

You’re flying the Corvalis, correct? You said 400, but I wasn’t sure if you meant the 404 or 408.

Anyhow, the Corvalis is a turbo-charged engine, and they end up behaving differently to a naturally aspirated engine like what you’d find in the 172.

Depending on how the turbo-charging system is setup, the mixture may not be something you have to adjust except in specific circumstances.

I am not intimately familiar with the Corvalis. I’d need to do a bit of reading on its induction system design parameters to understand how to answer your question accurately.

In very basic terms, the turbo-charger is meant to create sea level air density even when you are flying at high altitudes. However, all superchargers whether they be exhaust driven or mechanically driven, will reach a Critical Altitude point where they cease being able to compress the air to that sea level density. It is at that point when the mixture adjustment becomes important.

I think it is. I bought it for my VIP charter service and costed around 716000 cr. So I assume its that one?

And thanks for your understanding. Its really fun when you understand what you are doing. Now with the cessna 172 i almost learnt it myself all by myself. But now with bigger aircraft and different settings, it gets abit more complicated haha.

But I think I got you. Is it ok if i mark your comment as solution?

Of course.

Learning about aviation is endless. That aspect is one of my favorite parts about aviation. I can never know enough, there is always more to learn.

This game is so buggy. I was descending and got a warning that I entered a taxi way without approval :smiling_face_with_tear:

Yes. Career Mode needs quite bit of work to address the bugs and implementation issues.

Unfortunately, I can do nothing to help with that!

:joy:

Hahah thats ok! I just need to vent. Have lost so many hours because of these bugs. Been flying for hours, and just before i touchdown then suddenly unexpected error and crash.. :smiling_face_with_tear::grimacing:

Have you been enjoying any free flight between career building?

Some yes, but mostly only to try out an aircraft before I buy it on career mode. And some landing challenges. Why?

I’ve only done free flight in 24, and no career yet. Wondering if doing some free flight in-between your career lessons or missions is helpful to both practice and perfect whatever the career is showing a pilot. Thoughts? (Also, time for some unstructured fun flying.)

I would say it is helpful to practise and manouver the aircraft. Because on career mode you are rated how you handle the aircraft, landing smoothness etc. You will get paid less if you fly really bad, or even crash - which you then need to pay and repair your aircraft. Also your reputation would be affected.

I flew alot on msf 2020 so I jumped directly into career mode Because I missed exactly this, something to climb and develop.

Id say start, but if you feel that you are not ready while flying. Practise more.
But you will get some practise courses on career mode aswell while you are taking your certificates.
