Claim Text:
1. A method for controlling data transfer between a data providing device and an avionics device, the method comprising: operating in a device mode, by an intermediate device communicatively coupled between the data providing device and the avionics device, wherein the device mode allows the transfer of data to the data providing device from a storage medium of the intermediate device, allows the transfer of data from the data providing device to the storage medium of the intermediate device, disallows the transfer of data to the avionics device from the storage medium, and disallows the transfer of data from the avionics device to the storage medium, wherein the intermediate device has the storage medium and a switcher mechanism; and operating in an avionics mode, by the intermediate device, wherein the avionics mode allows the transfer of data to the avionics device from the storage medium, allows the transfer of data from the avionics device to the storage medium, disallows the transfer of data to the data providing device from the storage medium, and disallows the transfer of data from the data providing device to the storage medium, wherein only one of the data providing device and the avionics device is allowed to transfer data to or from the storage medium at a particular time while operating in the device mode and the avionics mode, wherein the data providing device is only indirectly communicatively coupled to the avionics device through the storage medium of the intermediate device while operating in the device mode and the avionics mode.
