Testing Methods of Checking the Correctness of Information Processing in the Avionic systems Integrated Along the Digital Databus MIL-1553B

The paper presents results of research that was carried out in the Air Force Institute of Technology (ITWL) with respect to test whether information in the avionic systems integrated along the digital databus MIL-1553B is processed correctly. The general part of the study deals with basic properties of the MIL-1553B databus and typical methods that are used to protect it from possible damages. In addition, standards procedures applicable to check correctness of data processing to the standard MIL-STD-1553B are also outlined. The second part goes into details related to methods that are used in the ITWL to test the MIL-1553B databus on the stages when startup and validation of an integrated avionic system are carried out, in particular those that were applied for upgrading of aircrafts operated by the Air Forces of the Republic of Poland.
