Aircraft section having a simplified rapid decompression architechture

An aircraft section, comprising:

• a primary structure forming at least a portion of an aircraft fuselage;
• a cabin floor coupled to the primary structure;
• a sidewall covering at least a portion of the primary structure, the sidewall having a first surface exposed to a passenger cabin and a second surface facing the primary structure;
• and
• a rapid decompression unit arranged between the sidewall and the primary structure,
• wherein the sidewall has a bottom edge arranged above the cabin floor,
• wherein a first distance between the bottom edge and the cabin floor is between 1 inch and 3 inches,
• wherein the rapid decompression unit is mounted to the primary structure and the cabin floor,
• wherein a second distance between the sidewall and a portion of the rapid decompression unit closest to the sidewall is between 1 inch and 2 inches,
• wherein the first distance is greater than the second distance,
• wherein the first and second surfaces of the sidewall converge towards the rapid decompression unit to form the second distance.
