FlightSim Studio Releases E-Jets 1.0 Out of Early Access

FlightSim Studio has released version 1.0 of their E-Jets series, formally ending a lengthy Early Access period that began with the E175 in January 2023.

The project has spent almost four years in development, perhaps becoming one of the more contentious Early Access stories in MSFS 2020/2024.

Version 1.0 is an update for the entire E-Jets lineup, meaning the E170, E175, E190, E195, E190F, and E195F.

In their blog post. FSS writes that they revisited several parts of the aircraft, noting that early builds relied heavily on MSFS’s default flight management and autopilot systems; the aircraft also lacked VNAV functionality and had limitations in LNAV and approach handling.

Over time, FSS moved the MCDU and flight-plan implementation to their own WASM-based infrastructure and eventually replaced the remaining MSFS-based autopilot with their own custom flight guidance system.

This custom autopilot is a founding pillar of the 1.0 update, and FSS says they now have more direct control over how the aircraft intercepts courses, captures altitudes, handles flight level change, follows vertical paths, and approach transitions.

The FMS has likewise been rewritten around the developer’s own logic, with VNAV, performance planning, SimBrief integration, and datalink functionality included.

Version 1.0 contents

The full release update has added an EGPWS terrain display, with look-ahead terrain alerts, Hoppie-based PDC and CPDLC functionality, ACARS weather and SimBrief integration, and a new MCDU flight-summary page. More work has been done on VNAV descent behaviour, fly-by turns, heading legs, flight-director logic, RNAV approaches, TCAS, electrical systems, GSX integration, and cockpit textures, according to FSS.

FSS stresses that the “full release” does not mean development is finished; they acknowledge there are still areas for improvement, and that the immediate priority is to address reproducible problems and regressions reported after release.

FSS has also published a “first-flight guide” for returning users. They say they want the public to approach 1.0 as a fresh aircraft, rather than flying it the way they learned to fly the older Early Access builds.
