Hi,
I’ve started using FS2020 6 monthes ago, i’m using a T16000 stick with an integrated slider for thrust control. For the first monthes, when I pushed the slider up or down to add or reduce engine power, the command was increasing or reducing rpm, and it was easy for me to adjust power exactly as I wanted. Since two monthes ago, the slider doesn’ affect rpm anymore (same planes) but affects manifold pressure instead. It’s very difficult to set the power exactky where I want it to be. When pressure reach a certain level, RPM are maxed. If I decrease pressure (gently pushing the slider down) rpm stay at max level until pressure reach a very low level. For me it has become very hard to control power since the behavior of the power slider has changed to pressure control rather than rpm.
I can’t remembered having changing anything in the game settings that would have associated throttle slider on the T16000 to man.pressure rather than rpm.
I can’t find any setting to return to the previous behavior.
Any help appreciated as it really degrades my flight handling.
PS : i’m new to FS2020 and new to flight in general, just being learning to fly on ultra-light albatros irl with 12 lessons passed 
So i’m kinda rookie 
What aircraft in the sim are you trying to use?
Diamond DA40NG, CTLS and VL-3.
This morning I tried the Robin DR-400 and I had direct control over rpm, so maybe it’s plane dependant.
You can map the slider to any variable or “axis” type of control you want. Access the Controls menu and double check that the slider is mapped to your throttle.
The Throttle in any aircraft works just like the accelerator pedal in your automobile. It controls the amount of air - and with that variable the amount of fuel - your engine is getting.
Manifold pressure is typically monitored in an aircraft equipped with a Constant Speed Propeller. The throttle’s function in those aircraft does not change, however, the way you monitor the power is different. RPM is held constant by a governor that controls the pitch (angle) of the propellor blades. That variable is controlled by the prop control (many times - but not always - colored blue) and is adjusted in concert with the throttle.
The DA40NG you mention is equipped with a constant speed propeller, so rpm should be constant in that aircraft in most circumstances. Like the Cirrus SR-22, the DA40 has a “single lever” engine control that eliminates the traditional “prop control” lever. The VL-3 you mention looks to have more conventional manual control of the propeller, using a traditional “blue lever” to control the pitch of the prop. The Robin DR-400 you mention has a fixed pitch propeller, so will not have a prop control and because of that, you’ll see engine (and propeller) rpm drop as you reduce throttle.
All three aircraft are very different in the way they handle power management, so having controls set up as a “one size fits all” solution will present a problem. Perhaps you could set up profiles for each of them in the Controls menu?
Hope this helps… cheers!
Thanks, that explains a lot of things i hadn’t understood.
So, that’s not a setting problem, but instead different ways to manage power based on different engine / blades technologies.
Helped me a lot !
