Air Pockets and Gravity Planes

Here's an explanation of how air pockets and gravity planes work aboard aetherships.

Air Pockets and Gravity Planes

The following diagrams illustrate the area of an aethership's air pocket along with the location and area of its gravity plane. 

As a general rule, the air pocket extends to port and starboard at a distance equal to the ship's beam width, and to fore and aft at a distance equal to the ship's keel length. Similarly, the pocket extends above and below the vessel at a distance equal to the height of the vessel as measured from the bottom of the keel to the top of the mainmast. 

An aethership's gravity plane is a flat surface that extends outward from the ship's keel, with an area equal to that of the air pocket. For this reason, characters are never upside down inside the vessel itself, but can walk along the bottom of the hull.
