Abstract: A lavatory is provided which includes a plurality of walls including a first wall having a doorway, and an expandable door. The expandable door includes a main panel having dimensions that conform to the doorway and a main hinge connecting the main panel to the first wall. The lavatory further includes a latch. The main panel is configured to, in a deployed state, increase in at least one dimension to form a privacy barrier around an expansion zone located outside of the plurality of walls. The latch is configured to lock the expandable door in place in the deployed state.

Abstract: A method and apparatus for an air circulation system. The apparatus comprises a suite and a circulation unit. The suite has walls extending upward from a floor of the passenger cabin without reaching a ceiling of the passenger cabin. The circulation unit comprises an inlet system configured to receive air in the passenger cabin of an aircraft in a location outside of the suite; an outlet system configured to output the air received by the inlet system into an interior of the suite; and a fan system configured to cause a movement of the air into the inlet system from outside of the suite and out of the outlet system into the interior of the suite. The air moves upwards in the suite and over the walls. The air moving over the walls causes a desired circulation of the air within the passenger cabin.
