  • Patent number: 5881973
    Abstract: A passenger door control set simulates the electrical sequencing and control circuits that controls the operation of an aircraft's passenger doors, allowing the door to be opened and/or closed, and substitutes for the normal sequencing and control circuits that were removed from the aircraft during its conversion to a freighter configuration. The set contains a portable equipment box and a portable door switch box, and a set of adapter cables in a kit. The equipment box is connected by selected cables to the overhead equipment panel connectors and the door switch box is connected to the door bulkhead connectors for the selected aircraft door. Indicators are provided at each box to perceptibly indicate the correctness of the hook up and availability of electrical power.
