• Yes

Provide extra information to complete the original description of the issue:
• edit: [NOT] Resolved when [Mixture] 100% 0 -100% event used [or any other event] with the Honeycomb Bravo throttle quadrant.

I only get fuel pressure before start by moving the mixture lever with the mouse.
Using the 100% 0 -100% mixture event allows the virtual cockpit lever to follow the hardware exactly.

I tried all Mixture Axis on my Honeycomb Bravo Throttle. Nothing worked.
Only the animation worked but there is no fuel.
When i push the Mixture lever with the mouse, it is working.

Hi folks,

Quick clarification for those of you experiencing this issue with the mixture not working correctly: is this on MSFS (2020), MSFS 2024, or both?

Thanks,
MSFS Team

For me FS2024 SU2, Win 11, Steam.
Don’t know about FS2020, not installed anymore.

I am using MIXTURE AXIS(0 to 100%) - it works for me. If your using SPAD or something similar might be conflicting. Also you will need to Set inverted Axis on the Bravo. At least that is what works for me.

Haven’t tried 2020.

It also does not work on the TB VFOne Yoke, have to ajust it using controller to recognize input. Mixture lever on yoke is fully functional.

Does not work with the thrustmaster airbus throttle. SMH fix this Carenado

Do you have the same issue if you follow the OP’s steps to reproduce it?
• yes

Provide extra information to complete the original description of the issue:
• same problem in VR, have to first grab and wiggle the mixture with mouse/ VR controllers in the virtual cockpit, before it works with assigned controls. It’s annoying that the animation works directly with joystick controllers but the logic behind it does not. Heard that this is a problem in several carenado aircraft.

No issue with a TM HOTAS Warthog throttle, using the using the small axis on the right side. I’ve always used -100 to +100 since that gives me a specific mid point, but either way should work. I don’t see any change in “fuel pressure” nor would I expect one, but I do see a distinct change in “fuel flow” as I would expect to see.
This is MSFS 2024, SU3 final, on MS Store PC version, no add-on’s/outside programs running.
Regards

After SU 4 MSFS 2024 , the problem still exist.

Starting cold and dark the mixture lever for a hardware binding (Bravo) doesn’t control the fuel until after fuel pressure has been added, and in order to do that , you can only move the mixture lever with the mouse during start up.

Reviving this thread. I also have this error, Turtle Beach Velocityone Flight.

MSFS 2024, PC, Store - this issue has existed since the aircraft was released and was discussed on Twitch streams (e.g.; twotonemurphy, CharlieFoxtrot00). A few other bugs have been corrected, but this one persists.
I have not been able to start the engine when using my Bravo mixture (which does move the mixture on screen, but no fuel flow occurs) until I move intentionally use the mouse to move the mixture from lean to rich.
