Aircraft interface device

An aircraft comprising:

• avionics equipment comprising a flight management system (FMS) and electronic engine controllers (EECs);
• non-avionics equipment;
• an aircraft interface device (AID) comprising:
• two or more data interface devices configured to communicate data;
• an external data transceiver configured to communicate to an external communication device;
• a power module configured to provide power to the two or more data interface devices and the external data transceiver, wherein the two or more data interface devices comprise:
• a first data interface device configured to communicate with the avionics equipment when the first data interface device is powered;
• and
• a second data interface device configured to communicate with the non-avionics equipment when the second data interface device is powered;
• a domain switch in signal communication between the power module and each of the two or more data interface devices and configured to selectively provide power from the power module to at least one of the two or more data interface devices;
• and
• a controller in signal communication between the two or more data interface devices and the external data transceiver and configured to provide a data communication path between the selectively powered data interface device and the external data transceiver for the external communication device, wherein:
• data from the avionics equipment is physically isolated on the data communication path when the first data interface device is powered and the second data interface device is unpowered;
• and
• data from the non-avionics equipment is physically isolated on the data communication path when the second data interface device is powered and the first data interface device is unpowered;
• a power source configured to provide power;
• and
• a power source switch coupled between the power source and the power module configured to selectively switch power from the power source to the power module.
