FSS News

Quick summary· AI-generated

FSS announced that E-Jets v0.10.45 is now the stable release, marking a major technical upgrade from the previous version. The update introduces a new WASM-based MCDU (replacing the old JavaScript version that became incompatible with MSFS 2024 after Sim Update 6), which substantially changes workflows and procedures — the developer recommends reviewing updated documentation before flying. The aircraft is now very close to v1.0 but still needs additional MCDU pages and autopilot refinement before reaching that milestone.

Excerpt from FSS News

Version 0.10.45 Becomes the New Stable Release Many of you have been following the development of the E-Jets for a long time. Your feedback and continued support have played an important role in helping the aircraft evolve far beyond its original technical foundation. Today, we would like to announce an important next step: Version 0.10.45 will replace the current stable version of the E-Jets.

Why We Are Updating the Stable Version The current stable version is no longer technically up to date. This became particularly apparent after Sim Update 6, which caused its MCDU to stop working properly. The reason lies in its technical foundation. The old MCDU was developed for Microsoft Flight Simulator 2020 and is based on JavaScript. The versions already available through the Experimental branch use a new WASM-based codebase that is compatible with Microsoft Flight Simulator 2024. This transition is more than an internal technical change. It provides a significantly more modern foundation for the MCDU and the continued development of the E-Jets. Version 0.10.45 is such a substantial improvement over the previous stable version that we have decided to make it the new stable release.

Please Read the Updated Documentation The new MCDU introduces fundamental changes to many workflows and operating procedures. Experience gained with the old version will therefore not always carry over directly to Version 0.10.45. Before your first flight, we strongly recommend reading our updated documentation like our MCDU preflight setup guide. There, you will find the latest information about operating the MCDU and its updated functionality. The documentation is the best starting point for becoming familiar with the new technical foundation and avoiding misunderstandings.

Why Is Version 1.0 Not Ready Yet?

At its current stage of development, the E-Jets are already very close to Version 1.0. Version 0.10.45 represents a major step forward and is ready to replace the previous stable version. However, there are still two areas we would like to improve before reaching the next major milestone. First, several MCDU pages are still missing and we would like to add them. Second, we are not yet fully satisfied with the behavior of the vertical autopilot in certain situations. We want to refine it further and give these improvements the careful testing they require. As is often the case in aircraft development, the final part of the journey…
