Propeller feathering in flight
-
I think there might be an issue (perhaps it is an MSFS limitation) with propeller feathering. My understanding is that when oil pressure is lost, the propeller will move towards the feathered position. I sometimes try to simulate an engine failure on one engine after takeoff. But unless I am really quick in doing so, the prop just keep spinning, even after putting the prop lever into the feather position. Could perhaps Nick (the developer) comment on this? I know that the relative wind makes a propeller spin, but is that simulation within MSFS 2024 entirely accurate?

I think this is the key part of your message. At takeoff, the propellers will be at their fully fine position. In this position, a loss of oil pressure due to engine shutdown will likely not be enough to feather the propellers. If you look at the engine visualizers, you will see the feather locking flyweights/pins (sometimes called "start locks") in the propeller hub that prevent the propellers from feathering during a normal shutdown. It's important to move the propeller lever to feather quickly after shutdown, before the propeller RPM drops below the speed at which the pins will hold the blades in their fully fine position.
Does that seem to match what you're looking at in the simulator?

Thanks Nick. I will have a look into it the next time. Do you happen to know any possible solution for this MSFS control issue that makes it difficult to put the props into feather using Bravo throttle quadrant? I can get it back almost to feather but I have to use my mouse to completely put the prop lever into feather..

You need a third party program to do it, the MSFS feathering controls have never worked on anything ever for me.
If you don't already have something like SPAD or FSUIPC, I think Mobiflight will do the job, and it's free.

I use SPAD.neXt with the Bravo throttle, and I use MSFS 2020 and 2024 controls for the propeller axis, and the following commands for the "reverse" detent (button) for the Bravo, for feathering:
Button pushed:
10 of the following pairs:
Send PROP_PITCH1_DECR-Event (or PROP_PITCH2_DECR-Event for Prop 2)
Delay execution for 100 msButton released:
Send PROP_PITCH1_HI-EventI find this to work in both 2020 and 2024.

I've been able to implement feathering all within MSFS2024 with the bravo throttle:
Propeller 1 axis - Joystick RAXIS Z - set inverted
Propeller 1 Pitch Hi - Joystick button 26 - set control on release
Propeller 2 axis - Joystick RAXIS Y - set inverted
Propeller 2 Pitch Hi - Joystick button 27 - set control on release
Toggle Feather Switch 1 - Joystick button 26
Toggle Feather Switch 2 - Joystick button 27 -
