Fenix Simulations has just released BFU Patch 1 for their Airbus A320 Family for Microsoft Flight Simulator 2020 and 2024.

The main highlights of the update are identifying and resolving several crashes and freezes, the improvement of VRAM usage up to 1.5GB in FS2024 and sound fixes such as missing sounds, incorrect CFM soundset issues and general volume issues.
