iniBuilds has recently rolled out a new update to their newly released A350 Airliner for Microsoft Flight Simulator 2020 and 2024, aiming to mitigate WASM crash issues and aid overall stability.

Update 1.0.3 focuses on making the product more stable and less vulnerable to WASM crashes that have plagued the product since its release, sparking a lot of controversy around many online flight sim communities. They have discovered that the update rates between third-party services and the A350’s systems sometimes don’t align, inducing issues, and specific data exchanges may cause unexpected increases in memory usage, leading to potential crashes. 

To further illustrate what has been going on with their A350, iniBuilds decided to provide an in-depth explanation of how the WASM system works and why it may, at times, stop working: it needs memory to run the avionics, custom systems, and other third-party add-ons, which isn’t random access memory, but its very own virtual memory running separately inside the simulator, which is allocated according to the demand, and allocation issues may happen, leading to a WASM crash (that either entirely kills the simulator or freezes the airplane’s system).

They have switched their method of handling that by going from manually managing memory to smart pointers, which helps prevent memory leaks and automatically handles freeing up memory when it’s no longer needed. Furthermore, they have taken steps to avoid using unnecessary copy constructors, which lead to high memory usage and performance issues. 

iniBuilds has also implemented a delay to third-party data requests. Previously, they requested data at 30 fps, which overwhelmed the WASM environment. Now, it only polls it once every second, reducing the memory and processing overhead.

The expected benefits of the above measures are fewer crashes due to bad memory management, more efficient memory use in the WASM environment, and better performance and smoothness. 

The A350 Airliner is available for purchase at the iniBuilds Store for roughly $76.16, requiring at least 10.63 GB of free hard disk space to install.
