Aircraft interface device

Abstract:

An aircraft interface device comprising two or more data interface devices, an external data transceiver, a power module, a domain switch, and a controller is disclosed. The two or more data interface devices communicate data, the external data transceiver communicate to an external communication device, and the power module provides power to the two or more data interface devices and the external data transceiver. The two or more data interface devices comprise a first data interface device that communicates with avionics equipment when the first data interface device is powered and a second data interface device that communicates with non-avionics equipment when the second data interface device is powered. The domain switch selectively provides power from the power module to at least one of the two or more data interface devices. The controller provides a data communication path between the selectively powered data interface device and the external data transceiver for the external communication device.
