v1.0.11 — October 16, 2026Latest
Synaptic Toolbox now required for terrain
Due to non-backwards-compatible changes made to support VSD terrain, the existing terrain server distributed through the iniManager will no longer work with v1.0.11 and beyond.
To install the necessary version of the terrain server, please install the Synaptic Toolbox. Moving forward, we will no longer be distributing the terrain server through iniManager, as moving to a self-managed platform provides for a more sustainable and maintainable process.

-
This should hopefully reduce the risk of the aircraft flipping on the runway during landing, though this is not a bulletproof solution ↩
-
Wing fold was used to simulate the drastic drop in lift when the ground spoilers are deployed, but may have also contributed to the aircraft flipping during landing ↩

-
This should help reduce the cross-track deviation observed when flying along the flight plan route; a more comprehensive review of these gains is planned for a future update which will also include localizer capture ↩
-
This manifested itself as persistent discontinuities in the flight plan on the map, despite the FMS
ROUTEpage showing no discontinuities; guidance remained unaffected in these cases ↩ -
This caused compatibility issues with third-party software such as Newsky and A Pilot's Life V2, and may have been responsible for incorrectly simulated flap damage with the simulator's default damage model ↩
-
This is expected to bring a sizeable improvement to performance, as less VRAM is used by the main displays and less time is taken on the graphics queue ↩
v1.0.3 — August 4, 2026
v1.0.2 is intentionally skipped
We submitted a patched package to the Microsoft Marketplace, which automatically bumped the MSFS 2020 version to v1.0.2. To keep the versions in sync moving forward, we are skipping ahead to v1.0.3.
The v1.0.2 build on MSFS 2020 is equivalent to the v1.0.1 build on MSFS 2024.

Your mileage will vary, but we've seen improvements to average FPS of up to 30% on some machines; further improvements will be continually made in the coming weeks ↩

We believe this may also resolve display issues with AMD 7000 series cards, but this is conjecture and has not been confirmed ↩

Known Issues
- If you do not see a blue preview needle on the HSI before LOC intercept when flying a LOC or ILS approach, select
HDGlateral mode on a course to intercept, then swap theNAV SRCmanually on the CTP and armAPPRon the FCP - Using the Native database with custom sceneries sometimes leads to the simulator's API incorrectly returning no ILS stations for the airport. When flying a LOC or ILS approach, verify that the correct frequency and course is tuned 31 nmi from the airport reference point.
- Starting a flight from mid-air does not initialize the aircraft correctly and causes it to drop out of the sky
