L-1011 Avionics Bending: SFENA HSI Power Up and ARINC 429 Test - Part 3

Not all HSIs have ADF data integrated right into the instrument. In most cases the HSI is paired up with RDDMI to give ADF/VOR and DME information. However, the SFENA HSI has pointers for two ADF channels which I think is a really neat feature of this particular instrument. The video below shows ARINC 429 words being sent on the slow 12Kb/sec bus with the ADF1 relative bearing data of 45ยบ nose right:



The ARINC 429 labels used in the example above are:
  • Label 162 - ADF Bearing Data (BNR)
