Analysis of Cockpit Voice Recorder compression reliability for airplane on demand blackbox data transmission

The black box records all the important information that takes place on a flying plane. The black box is a tool used on airplanes to store all activities during flight. The black box has a Flight Data Recorder (FDR) and a Cockpit Voice Recorder. FDR and CVR function to record and record the existing in the aircraft. The black box has recordings of information that occurs during the flight. Data generated FDR and CVR have a very large size is very difficult to transmit in real time. For that in this research make system that can divide data and compress data. The sound data in the conversion becomes binary by analog digital converter. The results of the data in binary form will be parsed into multiple partitions. Then the data partition into the compression process of data directly processed to obtain an efficient data size. The results of analysts seen from the size of data and time. In the conversion process becomes binary and parsing data takes about 223.4587466 seconds for 50 partitions. For time / partition takes about 4.46053 seconds. For compression takes 39614.72399 seconds for 50 partitions while for time / partition takes 792.2944798 seconds.
