| Aug 3, 2021 at 6:34 | comment | added | Craig | The two are actually quite different. ARINC429 is 32 bit standard while 1553 is 20 bit, encoding the 1 or 0 is bipolar return to zero vs Manchester II bi-phase, simplex vs time division multiplexing, 1553 needs a bus controller, bit rates are wildly different... could go on... | |

| Jul 11, 2017 at 18:14 | comment | added | selectstriker2 | The avionics I have worked (all civilian) with use ARINC 429 because that is what is predominately used on the aircraft. Hopefully someone might have some historical insight into the original aircraft that used Mil 1553 vs ARINC 429. I've also seen RS-232/422/485 used as the electrical standard | |
| Jul 11, 2017 at 17:44 | comment | added | mongo | My understanding (from integrating electronics into aircraft platforms) is that 1553 is used in civilian avionics devices. | |
