Elytra Aeronautics Port
by KIRILLAND
Elytra Aeronautics changes how the elytra behaves at altitude, so flight speed rises with height and long trips become practical.
What it does
The mod ports an earlier elytra aeronautics idea to newer versions. Flight speed increases with altitude, following the lower air density at high altitudes, which reduces air drag. With default settings speed climbs from y=0 to y=250, and beyond that mark it keeps increasing linearly up to a maximum at y=1000. At a constant altitude, flight speed holds steady at about 250 blocks per second, close to the average speed of a commercial flight.
Cloud layers appear in the sky as a visual reference for flight speed. They show where the speed begins to increase and where it stops increasing. Their number and placement can be set up to suit the player, and the extra flight speed can be turned off altogether. Fabric API is required, and ModMenu and Cloth Config must also be installed to reach the configuration screen. The mod runs on Fabric for 1.20.6 – 1.21.11, and both the server and every player need it.
Key features
Altitude-based speed
Speed scales with height, so climbing high makes the elytra cover much more ground per second than it does near the surface.
Cloud layer indicators
Layers of clouds mark the altitude bands where speed starts to rise and where the increase ends, acting as a visual speedometer.
Configurable flight
The number of cloud layers and the amount of extra speed can be adjusted, or the extra speed disabled entirely, through the configuration screen.
Long-distance travel
The mod targets elytra travel across large distances, such as moving between bases in a world up to 30,000 blocks wide.
