iniBuilds recently issued another update to their A350 Airliner for Microsoft Flight Simulator 2020 and 2024, improving core areas, fixing bugs, and adding larger new items.

The VNAV system underwent a major overhaul, with improvements to vertical profile adherence and constraint handling, as well as the addition of Constant Mach Segments, Continuous Descent Approach, and Estimated Take-off Time. 

Furthermore, iniBuilds has also added dynamic icing and snow effects, GSX integration for de-icing, and hot brake disc visuals on both platforms. 

The ECAM system also expanded with new fuel, icing, braking, and thrust logic alerts.

They have also done audio work to refine the cabin ambience, engine dynamics, and touchdown feedback, aiming to close the gap between their virtual rendition and the real thing.

Optimization work was carried out under the hood to warrant better performance, with code cleanups and restructuring reducing the overhead and thus improving the framerate. 

The complete changelog for the update follows below:
