The simple answer is that it's an established standard, sort of like an ISA-standard or PCI-standard is for personal computers. There are various ARINC standards...for various things...


Tons of other stuff on the ARINC site as well...

Arinc 429 (Arinc = Aircraft Radio INCorporated, a governing body concerned with the standardization of avionics) is a standard databus for data exchange between the various instruments/avionics/LRU's onboard an aircraft. Arinc 429 has a limited transfer speed of 100 kbit/s and there can only be one transmitter, and a maximum of 20 receivers.

There's also an advanced version, Arinc 629 (used on modern airliners like the 777 or 330/340). Arinc 629 has a maximum speed of up to 2Mbit per second and allows bidirectional data transfer for all connected stations.

Best regards,
