SU11 flighting information & release notes

Hello everyone.

Here are the release notes for the SU11 flighting version of the game.

SU11 Flighting online documentation available here:

The SDK 0.20.1 is available as well from the from the flighting version of the game.

Here are some important things to note, regarding this game version:

- The GLTF validator is now checking that the number of attributes of all vertices are identical for a mesh. This can trigger errors on package build and some of these errors are potentially caused by an error in the 3DS Max exporter. We are investigating this as we speak and will provide a fix in a later version of the SDK.

- The SimObject folder structure that was documented for SU10 will now be enforced on package build.
Check this page for more information: SimObjects (

- An issue with some airport projected meshes related assets being loaded upon airport selection in the world map and not being cleared when no longer needed has been identified. This will cause memory leak and require you to restart the game to free the memory. Our engine team is already working on a fix.

- A list of WASM changes detailed here: Post, WASM changes for SU11, Published Successfully (

@FlyingRaccoon @Boris_

I can't find any information on these variables in the flighting documentation.


Nothing in the engine sections, nothing in the simvars sections either.. Maybe they are missing on the docs? any information you guys could share about these vars?

Best Regards,

Sorry, they didn't make it into the documentation for the initial release. They will be in the next flighting SDK update.
