Abstract
A powered door opening mechanism includes an outdoor non-contact sensor provided outside an aircraft lavatory and configured to detect in a non-contact manner operation of a person holding a hand over the outdoor non-contact sensor, a human detecting sensor configured to detect the presence of a person inside the lavatory, an actuator configured to move a door, and a control unit configured to control the actuator. The control unit causes, in a case where the human detecting sensor detects nothing, the actuator to move the door from the closed position to the open position when the outdoor non-contact sensor detects a person.
