AIS-450 Synchro Converter 1A3C-2 The 21-50-339 is an externallyThe AIS 450 is a digital to synchro converter that receives angular dataheading, pitch, and rollvia two high speed ARINC 429 inputs and converts it into three SELSYN synchro outputs (3 wire). The inputs accept only angular ARINC 429 labels (314, 320, 324, and 325) and pass through valid data to the outputs. The first synchro output is mapped to either True or Magnetic Heading (ARINC 429 labels 314 or 320) based on the state of the Heading Select
