FSLabs A321neo Update: V11.0.1.309

We are excited to announce the release of v11.0.1.309 for our A321ceo and A321neo series – a comprehensive interim update focused on stability, visual performance, and real-world handling accuracy that continues our dedication to delivering the highest standards of realism, performance, and simulation fidelity.

One of the primary goals of this interim release is to improve performance and VRAM usage, particularly for users running in high-resolution or multi-monitor setups. This optimization helps ensure smoother performance and better headroom in memory-constrained environments, especially when flying complex approaches or in dense scenery areas.

We’ve also addressed several critical crash-to-desktop (CTD) issues, including those triggered by aircraft reloads and specific TCAS traffic situations. These changes improve the robustness of the simulation, making it more reliable across extended flights and varied operating conditions.

From a handling perspective, we’ve worked closely with airline partners and pilot feedback to correct an issue affecting yaw behavior during the landing roll, and have retuned brake effectiveness based on measured stopping distances from real-world A321 aircraft. These refinements offer a more authentic feel when decelerating after touchdown and enhance the overall realism of landing dynamics.

Alongside these improvements, this update also brings enhancements across a wide range of systems, including FMGC protections, NEO engine logic, ROPS behavior, and various smaller fixes to increase system fidelity and usability.

The following fixes and additions form part of this update, now accessible via the Experimental channel in the FSLabs Control Center.
