## Flight Simulator 2024 bindings

With the introduction of MSFS 2024 standards, the SWS Kodiak now fully supports Input Events (B-Vars) alongside traditional L-Vars. This provides more robust integration for hardware configurations.

B-Vars can be triggered using the following commands in your hardware configuration software (e.g., SPAD.neXt, AxisAndOhs, Mobiflight):

```
>B:Event_Name_Set
>B:Event_Name_Toggle
>B:Event_Name_Inc
>B:Event_Name_Dec
```
