Abstract

A method and apparatus for a hierarchical access system for a compartment. The hierarchical access system comprises a moveable barrier, a locking mechanism, and a control unit. The moveable barrier is capable of preventing access to at least one of a first space and a second space in the compartment in the lavatory when the moveable barrier is in a closed position. The locking mechanism is capable of securing the moveable barrier in the closed position. The control unit is capable of unlocking the locking mechanism in a manner that provides different levels of access to the first space and the second space in the compartment in response to receiving an access request.
