MSFS2020 aircraft - Light potentiometers at 100 when starting flight

Version: 1.0.77.0

Frequency: Consistently

Severity: High

Marketplace package name: AZURPOLY - TRANSALL C160

Context:
AzurPoly C-160 Transall in free flight.

Bug description:
We have several panel lights (declared as CIRCUIT_LIGHT_PANEL:#ID# in systems.cfg) which are used for instruments backlighting. Those lights do not have any associated lightdef, as they are simply used to manage a potentiometer value which will then light the panel using ASOBO_LIGHTING_Panel_Emissive_Template template.

On FS2020, all those potentiometers have a zero value when starting the flight (normal).
With same package on FS2024, those potentiometers have already a value of 100 when starting the flight.
The behaviour should be the same on both simulators (i.e. potentiometers = 0 by default).

Example of light knob in XML:

<UseTemplate Name="ASOBO_LIGHTING_Knob_Panel_Template">
   <SIMVAR_INDEX>8</SIMVAR_INDEX>
   <POTENTIOMETER>51</POTENTIOMETER>
   <NODE_ID>LIGHTING_Backlight_Center_Knob</NODE_ID>
   <ANIM_NAME>LIGHTING_Backlight_Center_Knob</ANIM_NAME>
   <TOOLTIP_TITLE>'PANEL CENTER BACKLIGHT'</TOOLTIP_TITLE>
   <TOOLTIP_TITLE_IS_DYNAMIC>True</TOOLTIP_TITLE_IS_DYNAMIC>
</UseTemplate>

Repro steps:

  • Load the AzurPoly C160 Transall (FS2020 package) inside FS2024 Community folder.
  • Launch a free flight on ground.
  • Check potentiometers values.
