Aviassembly is an engineering flight simulator where you don't just fly — you create. Build your plane from scratch, optimize every propeller, fuel tank, and skin, and then take to the skies to test your engineering ambitions. Fly the way you built it The game offers a meticulous design process where every element is important, from fuel weight to airframe aerodynamics. Once you've assembled the plane, you're immediately ready for real-world testing — delivering cargo, where fuel and balance are paramount. Each mission challenges your design and calculations. Earned funds can be spent on researching new parts and upgrades. By discovering new islands and biomes, you improve not only your plane but also your piloting skills. Become a master of the skies by exploring every corner of the open world. Game features Assemble the plane manually and customize all parameters to suit your needs. Physically precise control: takeoff, flight and landing require skill. Cargo missions with unique design requirements. Creative mode - no limits, just you and the sky.
