| Abstract: | RA system provides accurate measurement of absolute altitude （height above terrain）. In this paper, firstly, the working mechanics of RA of B757 is introduced. Secondly, the typical ab- normal working status of other systems caused by RA faults and the failure elimination procedure is analyzed. Lastly, the key points of maintenance of RA system are given and some maintenance suggestions are presented. |
