Incorrect description of flight beta throttle position in SDK docs

[MSFS 2024] Bug Reports SDK: Tools/Samples/Documentation
,
1

In the engines.cfg - Note on propeller pitch an throttle section, the docs say that:

  • When the throttle is less than or equal to min_flight_beta_throttle_pos then the propeller pitch is at beta_min.

  • When the throttle is at 0 then the propeller pitch is at minimum_on_ground_beta.

What is happening is that:

  • When the throttle is at min_flight_beta_throttle_pos, the propeller pitch is at beta_min
  • When the propeller is between min_flight_beta_throttle_pos and 0, the propeller pitch is interpolated between beta_min and minimum_on_ground_beta
  • When the throttle is at 0 the propeller pitch is at minimum_on_ground_beta

The actual behaviour in MSFS is correct and a welcome improvement, but the documentation does not reflect that and if I hadn’t tried it I wouldn’t know.

I will also open up a request so that reverse works the same way as this.

Hello @SWS-AlexVletsas

This is fixed in latest SU4 beta SDK and flighting documentation.

@FlyingRaccoon the documentation of the public SDK doesn’t match the flighting one. The new stuff “engines.cfg - Additional information” hasn’t transferred over.

@FlyingRaccoon I see the additional parameters are updated, but the main engines.cfg page doesn’t reference the new parameters at all. :smiley:

Hello @SWS-AlexVletsas

I’m not sure to understand, what parameters are missing from engines.cfg?

@FlyingRaccoon As of yesterday, the documentation doesn’t list the new parameters that are described in additional information. I.e. what category do the RPM and fuel flow limiters fall under? Turboprop_Engine? Propeller?

To help out with an image, this is the Additional information page, from where I’m trying to adjust the Kodiak’s governor:

Clicking on the prop_rpm_limiter_pitch_governor_pid I expected to get to the engines.cfg page and see the parameter table there. It takes me to the top of the page.

When searching for prop_rpm_limiter_pitch_governor_pid I get zero hits. So the documentation doesn’t include the parameter from “additional information” page, nor what section it falls under.

The Note On Propeller RPM Limiter section shouldn’t be visible.
This is a Sim Update 5 feature.
These parameters are not yet functional in SU4. Let’s call it a preview

Sylvain
