AIS-450 Heading Synchro Output | ARINC 429 Heading to Single Channel ARINC 407

Product Description

The AIS-450 Heading Synchro Output is a digital-to-synchro-based converter that receives angular data (heading) on two ARINC 429 inputs and converts it to one ARINC 407 synchro output (3-wire). The two ARINC 429 inputs are high speed (H/S) and accept only angular ARINC 429 labels for Heading, Pitch, and Roll (ARINC Labels 314, 320, 324, and 325). The ARINC 429 outputs are high speed (H/S) and pass through only the valid angular ARINC 429 labels received on the inputs.

The AIS-450 single channel has one ARINC 407 output that is configured as a 3-wire synchro. The output is mapped to the True or Magnetic Heading ARINC 429 label (314 or 320) depending on the state of the Heading Select Discrete Input. A High/Open state maps the output to Magnetic Heading, and a Low/Ground state maps the output to True Heading. The Synchro Validity Discrete Output indicates whether the ARINC 407 output is valid. The ARINC 429 Input 1 takes priority over the ARINC 429 Input 2.
