Release Notes - SU7 Beta 1.9.12.0 - September 18, 2026

RELEASE NOTES Sim Update 7 - Beta 2 - 1.9.120

If you are playing on PC, outdated packages in your community folder may have an unexpected impact on the title’s performance and behavior.

If you suffer from stability issues or long loading times, move your community package(s) to another folder before relaunching the title.

NOTE: Content downloads were disabled in the initial SU7 flighting builds (1.9.10.0 and 1.9.12.0) due to an unintended change that will be fixed in the next SU7 flighting update.

NOTE: The “Look Around” feature was mistakenly enabled in the initial SU7 flighting build, but is still in active development and will be disabled in SU7 flighting moving forward. This feature will not release with SU7.

New Content and Features

National Championship Air Races

National Championship Air Races (NCAR) pylon races are available to preview in 1.9.12.0, while STOL races will become available in an SU7 flighting update in the coming weeks. Please note NCAR is still a work-in-progress and will be unstable in certain scenarios.

Check the Known Issues section below for more information on what to expect. We will continue to make improvements to NCAR throughout SU7 flighting, but are eager to gather feedback on the current experience. Thank you for checking out NCAR and we look forward to your feedback!

To access the National Championship Air Races mode, on the title menu, select Activities > National Championship Air Races.
