A Deep Overhaul to Prepare for the Future of BeyondATC

If you've been following BeyondATC for a while, you'll know that most updates bring a mix of fixes and tweaks after implementing large features. Version 1.8.0 is a different kind of release. Since Early Access launched, the sim has grown considerably: new features, adjustments, and improvements have been layered in over time, and at some point it becomes important to stop and consolidate that work rather than keep building on top of it. That's what this update is. With VFR now in active development, we also needed the core foundations to be solid enough to support what's coming next. The timing felt right to go back through the systems that everything else depends on and rebuild them properly. Sequencing, vectoring, speech recognition, taxi routing, voice generation - each of these has been rethought and rewritten. We wanted to take a moment to walk through what actually changed and what it means for the experience.

A New Arrival Sequencer

The most significant change in this release is the arrival sequencer, which has been completely rebuilt from scratch. The new system uses a different approach to spacing: rather than reacting to aircraft as they get close, it starts planning from over 100 miles out, factoring in airframe characteristics and each aircraft's stage of flight to issue speed instructions proactively. The result is traffic that arrives naturally spaced rather than bunched, and a sequencing logic that's much closer to how real-world TRACON operations work. It's still being refined, but it's already a meaningful step forward.

Smarter Vectoring

Vectoring has also been completely reworked, now at its third major iteration. The new system accounts for wind, terrain, drift, and reaction time when generating instructions, and can adapt paths in real time as the situation around you changes. The goal was to produce instructions that are minimal and accurate rather than frequent and approximate, and that's what version 3 delivers.

Speech Recognition and Communications

Two interconnected systems have been overhauled here. The communications platform has been rebuilt with a focus on stability, addressing the kind of intermittent issues that are hard to pin down but frustrating to encounter. Speech recognition has been upgraded alongside it, with smarter readback handling that tries to understand intent rather than relying purely on transcription accuracy. When a microphone input is corrupted or unclear, the system now has layered fallback handling to resolve it gracefully rather than simply rejecting the readback.

Ground Operations

Taxi routing and departure queue handling have both been rebuilt. Routes are cleaner and generated faster, ground communication is less intrusive when aircraft are already moving in the right direction, and the departure queue system now handles deep queues on busy days without issues. Taken together, ground operations should feel noticeably more fluid.

Local Voice Model

Local voice generation has taken a meaningful step forward in this release. The local voice model now covers the same range of accents previously exclusive to premium voices, running entirely offline with no noticeable performance overhead. This is part of a longer roadmap: local voices will eventually replace the Basic voices entirely as the model continues to mature.

Stability

Alongside the headline changes, a significant number of stability fixes have gone into this release: stuck traffic, altitude readback rejections, edge case crashes, and more. These aren't the most visible improvements, but they matter. Getting BeyondATC into a reliable state ahead of the 1.0 release out of Early Access is a clear priority, and 1.8.0 reflects that commitment.

What's Next

1.8.0 will remain in Experimental for a few weeks while we verify stability and the effectiveness of the changes. Once we're satisfied, it'll move into the main Early Access branch and at that point, Experimental shifts focus to something a lot of you have been asking about: VFR. Stage 1 is well underway, and a demo video is on its way soon. It's a significant addition to the sim and deserves its own proper introduction when the time comes.

In the meantime, thank you to everyone who has submitted bug reports, shared feedback, and supported the project through Early Access. A lot of what went into this release came directly from what the community flagged and discussed. It makes a real difference, and we genuinely appreciate it.
