Brief description of the issue:

As i don’t have enough axis on my joystick I have to assign the commands increase/decrease propeller pitch to buttons. The problem is, when I try to reduce the prop slowly, by pressing several times the buttons, the prop levers don’t move simultaneously. One of the levers moves much more backward than the other. The only way to correct the difference is moving the lever with the mouse. As you can imagine, even with track ir, it’s very difficult, particularly on take off or approaching.

I’ve tried to use the command “Inc/Dec propeller pitch (slow)” and it happens the same.

And I’ve tried with several planes (all of them are default planes: Baron, Dc3, etc) too.

Provide Screenshot(s)/video(s) of the issue encountered:

I’ve found a video on youtube:

Detailed steps to reproduce the issue encountered:

Load any twin engine and move the levers using these commands. With engines running or not, it happens the same.

PC specs and/or peripheral set up if relevant:

I’ve checked this problem with the next hardware: MS FFB2, CH yoke and VKB Gladiator II. With all of them happens the same.

Yes! I’m having this problem since ages, I bought a throttle quadrant but today it kicked the bucket… and had to come back and assign keys… I’ve sent a zendesk ticket and they inmediately mark it as solved… does anybody know if there is a walkaround for this mess?

Same on Xbox X with binding of increase / decease RPM (prop pitch). Has always done this but seems more so after SU9

I was about to post the same bug.

When I FIRST pressed the joystick button bound to DECREASE PROPELLER PITCH (SMALL), the #2 engine prop pitch decreases TWO steps, while the #1 engine decreases a single step. Subsequent presses of the button decreased prop pitch by one step in both engines. So basically the #2 engine is one step lower all the time.

INCREASE PROPELLER PITCH (SMALL) is fine, it increases the prop pitch by one step on both engines equally.

I’ve reproduced this bug in the Default Baron G58 and Grumman Goose.

yes

Provide extra information to complete the original description of the issue:

Pressing the key slowly increases the difference between the two levers. The levers will stay in sync if the key is pressed in quick succession or held down. The bug sometimes goes away during flight, but I can’t figure out when or how.

i have the same issue, this issue has been occurring in the sim for a long time.

YES

Provide extra information to complete the original description of the issue:

Happens as described, I use a button box that acts as a joystick. The way I found to circumvent this issue is to first hit the increase key and then you can decrease the rpm with the levers remaining syncronized, wich is not ideal..

Yes

The sim will also crash to desktop when using the keyboard command for the prop axis about 50% of the time.

Why isn’t this bug labeled as “bug logged” or, at the very least, “feedback logged?”

I wish MS would give me the job of bug management for the forum and external testers. I’d like to see the entire bug management be more organized and managed. I’d gladly take that on. It’s a massive program with a massive bug list that needs a key player organizing it.

There are so many bugs that have no labeled acknowledgement, which leaves me wondering what happens to them.

I’ve tried this workaround but it didn’t work for me :frowning:

Yes

Provide extra information to complete the original description of the issue:

When pressing the button on my keyboard to decrease RPM slowly, the difference in lever positions is larger. No2 RPM decreases faster than No1. When decreasing RPM quickly, No2 RPM decreases first, then both decrease at the same speed.

I still have the same issue in January 2024. I can’t believe such a basic operational bug has not been addressed yet.

I thought I am the only one having this bug :rofl:

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:

This seems like a larger key-repeat bug that impacts not only propeller pitch, but cowl flaps. There are several controls that are affected:

  • [increase/decrease] propeller pitch
  • [increase/decrease] propeller pitch (small)
  • [increase/decrease] propeller [1/2/3/4] pitch
  • [increase/decrease] propeller [1/2/3/4] pitch (small)
  • [increase/decrease] cowl flaps

The bug impacts these controls if they are assigned to any keyboard key or any controller button. Repeated presses of the control (key or button) results in increased “step” movements of the lever shown in the cockpit. For example, if “decrease cowl flaps” is assigned to the keyboard’s ‘F’ key, pressing ‘F’ once will close the cowl flaps by a small amount. However, if the ‘F’ key is pressed again in quick succession (less than 0.5 seconds or so) the cowl flaps will close by a larger amount (about double) of the first press.

This impacts propeller pitch controls in the same way — subsequent presses of “decrease propeller pitch” result in larger changes in the cockpit lever — but is exacerbated when flying multi-engine airplanes, because the second (and third, fourth, etc.) engine’s propeller pitch is affected by the first’s key repeat behavior. This results in propeller pitch falling out of sync between multiple engines, again, when controlling it with a keyboard or controller button.

One final note: this bug, for unknown reasons, resolves itself once Flight Simulator has been open for more than 45-60 minutes. After that point, propeller pitch (even in multi-engine) and cowl flaps work perfectly as expected, until the game is closed down.

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:

I’ve tried several keybind combinations with my MU-2 twin turbo prop. Simply using “Increase Propeller Pitch” or “Increase Propeller Pitch (Small)” or binding “Increase Propeller 1 Pitch” and “Increase Propeller 2 Pitch” to the same key. Or also combining “Increase Propeller 1 Pitch (Small)” with “Increase Propeller 2 Pitch” to see if that would fix the issue. But nothing worked. This of course also applies to the binds to decrease prop pitch.

We have April 2024 and still this bug exist in the Sim .

Plz Asobo look into it.

This issue has bugged me (no pun intended) from the start … still there with SU15. Propeller pitch is bugged but using the same buttons for adjusting mixture works fine. Hope to see this fixed in a future patch.
