  • Publication number: 20180341794
    Abstract: Disclosed is a method of radio frequency identification communication (RFID) between an avionics system and an RFID reader. The method includes connecting to a wireless RFID tag in the avionics system with the RFID reader while proximate to but not touching the RFID tag. The RFID reader receives, via wireless communication from the RFID tag, system data at the RFID reader comprising one or more of prognostic data and diagnostic health data associated with the avionics system. The RFID reader then displays, on a graphic user interface, the system data such that the system data is user-selectable for identification of one or more avionics system errors. The RFID reader synchronizes, via a communications interface on the RFID reader, the system data with a maintenance server.
