The Create Aeronautics mod allows players to construct and pilot various functional vehicles in Minecraft, enhancing the game's engineering possibilities. It builds upon the Create mod and introduces three key components:
1. Simulated - Adds new block types, redstone components, and tools, allowing players to bond components using slime.
2. Offroad - Focuses on terrestrial vehicles, enabling the creation of engines, suspensions, and round(ish) wheels, with applications for agricultural machinery.
Players must have the Create mod and the Sable mod, which introduces a physics pipeline, installed to use Create Aeronautics.
