Patent attributes
An in-flight entertainment and communications (IFEC) system configured to stream vehicle operational parameters from avionics systems connected thereto. An avionics interface defines a node of an avionics bus, and the avionics systems are connectible to the avionics interface over the avionics bus to transmit aircraft operational parameters thereto as a raw stream of chronologically sequenced data elements. A data processor is connected to the avionics interface and a network interface, and is receptive to the aircraft operational parameters from the avionics interface. The data processor applies a variable filter that selectively passes a filtered data stream of aircraft operational parameters derived from the raw stream to a data storage device. The variable filter is defined by one or more filter parameters dynamically adjustable in response to changing conditions derived from the aircraft operational parameters. The filtered data stream is transmitted to the remote monitoring station.
