Coal powers your city and allows you to do this, so make sure that as soon as you access the tech tree you go to the coal storage option and increase it by 200%. In Airborne Kingdom, you will be constantly fighting gravity to keep your city and its civilization residing upon the sky. You can prevent this happening whenever you introduce a new infrastructure to your airship by researching at the tech tree under 'Lift' so you are able to introduce new attachments like balloons, rotors, wings, and fans to compensate.

You need to ensure that your floating city has enough Lift at all times, otherwise it will descend to the ground and crash. It is crucial in Airborne Kingdom that you regularly check your Lift by hovering over the 'Lift' option. Take advantage of this skill whenever your floating city loses balance or has a tilt that needs fixing. Your floating city has a center of gravity, and this skill enables you to move facilities away from the tilting point so that you rebalance the airship. Water filters will boost the condenser in its range, and windmills will boost any farm in its range. You will also get a boost if you place windmills and farms together. If you place the food and water buildings close together, you will be able to acquire a boost in Airborne Kingdom. Place Food and Water Buildings Close Together

For example, in the first realm you will be able to unlock farms and water condensers which will provide you with unlimited food and water resources, things that are hard to acquire in the subsequent realms. It is therefore essential that you take your time and make sure you get everything you need before you move onto the next realm. There are three realms in the Airborne Kingdom to unlock and each provides you with opportunities to unlock valuable resources which you may not be able to get in the other two realms.
