Cost reduction system and method for flight data recording
First Claim
1. A system for recording aircraft parameter data, the system comprising:
- a voluntary data acquisition unit for acquiring voluntary parameters describing the aircraft and forming a voluntary data stream comprising the parameters describing the aircraft;
a mandatory data acquisition unit in communication therewith for receiving the voluntary data stream and combining the voluntary data stream with the mandatory parameters into a single merged data stream; and
a flight data recorder in communication with the mandatory acquisition unit, wherein the flight data recorder is for storing the merged data stream;
wherein merging the voluntary data stream with the mandatory data comprises interlacing the mandatory parameters with the voluntary data stream such that the mandatory parameters have predetermined locations within the merged data stream, and wherein merging the voluntary data stream with the mandatory data stream does not require the re-certification of the flight data recorder.

Abstract
A method and system for acquiring aircraft parameters that includes sampling an aircraft parameter during a first sampling period, recording the full value of the aircraft parameter sampled during the first sampling period, then sampling the aircraft parameter during a fixed number of subsequent consecutive sampling periods, and recording the change between the value of the aircraft parameter sampled in the subsequent sampling periods and the value of the aircraft parameter sampled in the prior sampling period. A method and system for constructing a data stream that includes merging a voluntary data stream and the mandatory parameters and storing the merged data stream in a flight data recorder while maintaining the certification of the flight data recorder.

7. A method for constructing a data stream, comprising:
-
receiving a voluntary data stream from a voluntary data acquisition unit, wherein the voluntary data stream comprises voluntary parameters describing the aircraft; receiving a mandatory data stream, wherein the mandatory data stream comprises mandatory parameters describing the aircraft and required to be recorded by at least one government mandate, and wherein the voluntary parameters are not required to be recorded by the at least one government mandate; merging the voluntary data stream and the mandatory data, wherein the merging comprises interlacing the mandatory parameters with the voluntary data stream such that the mandatory parameters have predetermined locations within the merged data stream; storing the merged data stream in a flight data recorder; wherein the merged data stream maintains the certification of the flight data recorder. - View Dependent Claims (8, 9, 10)
