Nearing the end of early access
Quick summary· AI-generated
FSS's E-Jets aircraft has reached v1.0 after an extended Early Access period. The article explains the major development milestones: a complete custom autopilot rebuild to replace MSFS-based limitations, substantial rework of the flight deck displays (PFD, IESS, EICAS) with custom WASM systems for performance gains, and underlying code restructuring that ensures consistent behavior across flight phases. The authors frame v1.0 not as feature-complete but as meeting a stability and core-experience standard they set for exiting Early Access.
Excerpt from FSS News
Finally! The FSS E-Jets have reached version 1.0, and the Early Access period is over. The update is available now in Aerosoft One and Contrail App.
Many of you have been flying the E-Jets since the first Early Access release. You have shared flight reports, pointed out problems, challenged our decisions and returned after each update to see what had changed. That involvement has shaped the aircraft we are releasing today. This is a milestone in a project that has taken longer than we originally expected. We want to explain what stands behind the version number rather than ask you to take it on faith. What changed along the way The E-Jets did not reach this point through one large update. During Early Access, we added features, reworked our code structure and changed underlying systems. We also learned where an incremental fix would leave us with the same limitation later. In those areas, we chose to rebuild.
That work is not always obvious in a screenshot. It matters when the aircraft follows a route, captures an altitude, transitions into an approach and behaves consistently from one flight to the next. A better foundation also gives us more control over future changes.
Not every part of this journey has been as smooth or as quick as we wanted. We know that. Version 1.0 is our statement that the core experience has reached the standard we set for ending Early Access; it is not a claim that every issue or every future ambition has been completed. Because it probably never will be. Flight guidance: a new autopilot foundation The most significant change for version 1.0 is the custom autopilot. Rather than continue to work around the limits of the previous MSFS-based approach, we rebuilt the flight guidance foundation so we can control its behavior more directly.
For a pilot, the point is not the architecture itself. It is how the aircraft responds when you select a mode, intercept a route, capture an altitude or fly an approach.
We made this investment because flight guidance touches so much of the E-Jet experience. It is the clearest example of what Early Access allowed us to do: revisit a fundamental decision when we had learned enough to build a stronger solution.
Avionics that have evolved The flight deck has also changed substantially since the original Early Access release. Work on the PFD, IESS and EICAS moved important display logic into our own WASM systems. That gives as a significant performance boost while we can…
