[IDEA] Make PROP BETA writable

Can the PROP BETA variable be made RW instead of RO? This way we can have control of the propeller beta angle and make custom governor logic, beta range and anything we need for our propeller engines.

Yes please! this would allow me to code my current project better behavior much better since the airplane has dual mod between auto prop and a governor.

YES PLEASE!!

This will also allow us to make electric variable pitch propellers, simulate prop governor failures and better feathering behaviour.


Big +1 from me!

@FlyingRaccoon

Have you guys had the chance to discuss this? it would be really helpful. As per this Topic: https://devsupport.flightsimulator.com/questions/3021/turboprop-beta-moderange.html

Having the ability to write this variable (even if we have to override it on each frame) would allow us to do customs solutions much nicer.

I am having to do some weird whichcraft at the moment to move the beta angle on ground, which can have detrimental effects to engine thrust, etc.

The operation of almost ALL modern turbo props engines requires this, it is how PT6 engines are designed, I checked the TBM 900 default airplane configuration and the Caravan, and they are also lacking this capability despite of having a PT6 engine, so we would all benefit from having new functionalities via this variable.

And if you guys need any help, I am more than willing to implement the "beta" operation range for the TBM and Cessna Caravan so you guys can focus on something else, I just need more SDK POWER to be able to do these things, please, please, please!!

Best,
Raul

Bumping this thread. As the beta range feature has no ETA, is there a chance that this A:var becomes writable so we can make our own solutions?

Hello @SWS-AlexVletsas, @MrTommymxr & @Simbol

Starting from SU10, we'll expose new simvars and events that will allow you to do this.

Simvars:

PROP BETA FORCED ACTIVE: boolean
PROP BETA FORCED POSITION: 16k position representing an angle between -180° and 180°

Events:

First parameter always is the index of the prop (using 0 applies to all props)

KEY_PROP_FORCE_BETA_OFF

KEY_PROP_FORCE_BETA_ON

KEY_PROP_FORCE_BETA_SET: 2nd parameter is a boolean

KEY_PROP_FORCE_BETA_TOGGLE

KEY_PROP_FORCE_BETA_VALUE_SET: 2nd parameter is the angle as a 16k pos in [-180;180]

Let us know when SU10 flighting begins if that covers your needs.

Regards,
Sylvain

So they're K:2 events.

The set events are yes.

Perfect! Thankyou so much Sylvain and Asobo team for the support for this.


I will implement with SU10 flight and report feedback accordingly.


Once again very much appreciated the support to move turboprop engines one step closer to real world.


Best,

Raul

@FlyingRaccoon while testing the default turboprops in SU10 beta I notice that when you put the engine into beta/reverse, the prop lever moves all the way back and feathers.

Hi Alex, @SWS-AlexVletsas


I am not experiencing this, but I have disabled the propeller lever controls:

[DISABLED_CONTROLS]
DisablePropellerControls = 1;

Which is fair since we are going to manage the beta angle ourselves.. in the case of our current projects we don't want the users with "propeller lever axis" to change the beta angle anyway since this is all done via the PT6 engine system.

Best,
Raul

This doesn't apply to planes like the 208, KA350 and Kodiak, as they still have a propeller lever.
Also @FlyingRaccoon the feathering is my fault. I had "toggle propeller reverse thrust" assigned to the same button as throttle reverse and that caused the feathering to happen. I'll make a post regarding the other bug.

Hello @SWS-AlexVletsas

Please post a dedicated question in the SU10 space and tell us which aircraft you tested.
