Abstract: There is provided a system for securing a cockpit from a cabin. A lavatory door has a locking mechanism provided thereon. A latching mechanism is provided on an adjacent structure across an aisle from the lavatory. The locking mechanism is compatible with the latching mechanism to secure the lavatory door in an open position, thereby forming a secure area for entering from the cockpit.

Abstract: An aircraft lavatory includes first and third walls extending inwardly from a second wall and a fourth wall connecting the first wall to the third wall. A countertop extends along a portion of the first wall. A sink is disposed in the countertop. The countertop defines an under-countertop recess free from obstructions. A toilet is disposed adjacent to both the second wall and the third wall and defines a toilet axis bisecting the toilet. A door extends along at least a portion of the third wall. An access axis is defined that is disposed at an access angle with respect to the toilet axis. When a person in a wheelchair enters the lavatory area along the access axis, the countertop recess accommodates at least a portion of the person's body.
