BKSQ Caravan Pro bush trips compatibility

This add-on provides a standalone compatibility utility for the Black Square Caravan Professional in MSFS 2024, ensuring the auxiliary battery follows the main battery switch during bush trips. It helps with proper mission completion by preventing unintended power retention after engine shutdown. The module works with multiple Caravan Professional variants and does not modify simulator or aircraft files. Installation is done via the Community folder and no additional tools or dependencies are required.
