Abstract
An oxygen supply system for delivering oxygen to passengers in an aircraft in an event of a loss of cabin pressure includes a source of oxygen, a passenger service unit, and a main controller. The passenger service unit includes a face mask configured to facilitate a flow of an accumulated volume of oxygen from the source of oxygen, and a sensor configured to detect at least one of an ambient pressure, an airflow in a first direction, or an airflow in a second direction. The main controller is configured to determine at least one of the ambient pressure, the airflow being in the first direction, or the airflow being in the second direction, and command delivery of oxygen from the source of oxygen to the face mask in response to the determination.
