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.

First claim

What is claimed:

1. An aircraft interface device (AID) configured for deployment on an aircraft, the 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 avionics equipment when the first data interface device is powered; and
a second data interface device configured to communicate with 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.

2. The AID of claim 1 , wherein
the avionics equipment is configured to provide the data from the avionics equipment that includes aircraft control and aircraft information data, and
the non-avionics equipment is configured to provide the data from the non-avionics equipment that includes broadband Internet access and/or passenger information and entertainment data.

3. The AID of claim 2 , wherein
the aircraft control and aircraft information data is physically isolated on the data communication path when the first data interface device is powered and the second data interface device is unpowered,
the broadband Internet access and/or the passenger information and entertainment data is physically isolated on the data communication path when the second data interface device is powered and the first data interface device is unpowered, and
the controller comprises a processor that is configured to run one or more virtual machines, wherein a first virtual machine is configured to process the data from the avionics equipment and another virtual machine is configured to process the data from the non-avionics equipment.

4. The AID of claim 2 , wherein
the aircraft control and aircraft information data is physically isolated on the data communication path when the first data interface device is powered and the second data interface device is unpowered,
the broadband Internet access and/or the passenger information and entertainment data is physically isolated on the data communication path when the second data interface device is powered and the first data interface device is unpowered, and
the controller comprises a processor and a computer-readable medium,
wherein the computer-readable medium is configured to store software instructions that when executed by the processor causes software containerization, and
wherein the processor is configured to process the data from the avionics equipment and the data from the non-avionics equipment while physically isolating the aircraft control and aircraft information data and the broadband Internet access and/or the passenger information and entertainment data.

5. The AID of claim 2 , wherein the controller is further configured to
enable the external communication device to communicate data to the avionics equipment via the data communication path when the first data interface device is powered, and
enable the avionics equipment to communicate flight information to the external communication device via the data communication path when the first data interface device is powered.

6. The AID of claim 5 , wherein the controller is configured to enable a hosted application on the external communication device to communicate data to the avionics equipment.

7. The AID of claim 2 , wherein the controller comprises a processor and a computer-readable medium, and the controller is configured to host applications.

8. The AID of claim 7 , wherein the controller is configured to enable a hosted application on the controller to communicate data to the external communication device.

9. The AID of claim 7 , wherein the controller comprises a trusted platform module (TPM) configured to secure the AID through integrated cryptographic keys.

10. The AID of claim 2 , wherein
the external data transceiver comprises a wireless data transceiver configured to provide a secure wireless communication network for the external communication device, and
the wireless data transceiver is a Wi-Fi data transceiver, Bluetooth data transceiver, near-field communication (NFC) data transceiver, or Internet of Things (IoT) technology transceiver, wherein the IoT transceiver comprises an IoT protocol utilizing IEEE 802.15.4.

11. The AID of claim 10 , wherein the secure wireless communication network is a virtual private network (VPN) configured to communicate with one or more communication end points.

12. The AID of claim 10 , wherein the external communication device comprises one or more wireless smart devices configured to communicate with the wireless data transceiver via the secure wireless communication network.

13. The AID of claim 12 , further comprising
a cellular transceiver comprising a second secure wireless communication network configured to communicate between the one or more wireless smart devices and an external cellular device,
wherein the second secure wireless communication network is configured to communicate application software comprising business and/or flight operations to the one or more wireless smart devices and/or the avionics equipment.

14. The AID of claim 13 , wherein the cellular transceiver comprises a 3G cellular transceiver, 4G cellular transceiver, or 5G cellular transceiver.

15. The AID of claim 14 , wherein the cellular transceiver includes a subscriber identification module (SIM) configured to securely store a subscriber identity of a user of the external communication device.

16. The AID of claim 15 ,
wherein the SIM includes cellular service data, and
wherein the cellular transceiver is configured to automatically switch between a plurality of cellular service providers based on a location of the aircraft such that the external communication device appears as a local device on a cellular network of a corresponding cellular service provider of the plurality of cellular service providers.
