Valheim Aviation — single-player alpha 0.1.1

Take to the skies in a crude, single-seat biplane. Learn to handle the wind, watch your fuel, and bring your aircraft home in one piece.

Windows / Steam / single-player only. Tested with Valheim 1.0.17. Multiplayer, dedicated servers, other mod combinations and future game updates are not verified. Use a separate test world and character; back up saves before testing.

Fly the alpha

• Pilot your own biplane: taxi, take off, bank, climb and land with working control surfaces.
• Feel the weather: gentle winds drift you off course; storms challenge your handling.
• Look after your engine: refuel with spirits, start it by hand, and hear it respond to the throttle.
• Care for your aircraft: repair damage with a hammer and shelter it from rain.
• See your landings leave a mark: runway dust, water spray and breakup effects bring contact with the world to life.

This is a testing alpha. The aircraft uses an unfinished prototype model. Spawn the plane and fuel through console commands; crafting and finished artwork will follow.

New in alpha 0.1.1

• Faster propeller rotation with smooth coast-down and a small amount of airborne idle thrust.
• Spinning blades damage creatures and players, and impacts can damage the aircraft. Solid obstacles stop the propeller and engine; clear the obstruction before restarting manually.
• Three-second refuelling with a yellow progress bar, native crafting animation and cancellation without losing a bottle. Existing pour sounds retained.
• Recovery of saved aircraft after unexpected scene loss, plus pause-aware restoration.

Alpha screenshots

These screenshots show the current prototype model; final artwork and crafting are still in development.

Hard crashes can break the aircraft into separate pieces.

Install

Install Valheim Aviation through r2modman or Thunderstore Mod Manager; the declared BepInExPack Valheim and Jotunn dependencies will be installed automatically. For a downloaded alpha ZIP, import it as a local mod in a fresh profile. For manual installation, merge the ZIP's BepInEx folder into the game folder after installing dependencies. Keep aircraft.assetbundle beside ValheimAviation.dll. Do not install duplicate copies. The included configuration is part of this alpha: it enables the accepted fuel, damage, noise and weather settings.

Add -console to launch arguments. Load a single-player test world, press F5, enter devcommands, then:

• aviation_spawn — spawn one plane ahead of you; use a clear, open area.
• aviation_fuel_give — receive placeholder Strong Spirits fuel (temporary resin appearance).
• aviation_status — aircraft diagnostics.
• aviation_repair — repair the nearest aircraft within 10m; hammer repair also works.
• aviation_remove — remove the most recently tracked aircraft, not necessarily the one you are looking at. Avoid using this around aircraft you want to keep.

Close the console. Press E at the fuel tank to add one bottle of spirits over three seconds, with a yellow progress bar and a workbench-style animation. Walking or jumping cancels without consuming the bottle. Four items fill an empty tank. Interact with the engine to start it, then the seat to board.

Controls (default game bindings)

Control	Action
Hold Left Shift (Run)	Increase engine power; release to wind down
W / S	Pitch nose down / up
A / D	Roll left / right
Q / E	Rudder and ground steering
Left Ctrl (Crouch)	Wheel brakes with ground contact
Hold X (Sit)	Dismount, including in flight
Mouse wheel	Camera zoom

Use gentle throttle for taxiing. Allow runway space; slopes, wind and initial engine power change the takeoff distance. Avoid thunderstorms until comfortable flying. A quarter tank is added per fuel item; approximately 10 minutes of fuel at full engine speed. Check tank fullness by looking at it. The plane can stall and crash.

Saving, damage and weather

Aircraft persist across reload and travelling away in single-player. Rain wears exposed parked aircraft down to half health; a full roof protects them. Sustained partial submersion also stops at half health; deeply submerged wrecks eventually decay away. Destruction creates short-lived debris, with no salvage drops yet.

Aircraft records are separate from native world saves: back up BepInEx/ValheimAviation/persistence with your world. Mod-manager profiles have separate BepInEx data directories. Moving to another profile without this folder can make planes appear missing. Uninstalling hides aircraft; retained records can restore them if the mod is reinstalled. Fuel items are custom items: use a disposable test character.

Feedback and known limitations

Unfinished prototype artwork, placeholder fuel, console-only acquisition, no multiplayer, no salvage, and no guarantee of save-format compatibility across alpha updates. Decorative debris is not recoverable.

Share feedback in the comments on a Valheim Aviation video on our YouTube channel. Please include the mod/game version, what you were doing, what happened, and whether you can repeat it. Terrain, weather and other installed mods help us investigate. Keep relevant flight logs and BepInEx/LogOutput.log in case they are requested; review them for personal information before sharing. There is no Discord support channel at present.

The local black box records piloted flights under BepInEx/ValheimAviationBlackBox/flights; nothing is uploaded automatically. Recording is capped at 128MiB per flight and 1GiB total; it can be disabled in the FlightRecorder configuration. Preserve relevant logs before more testing.
