Ex. XIII

ARINC has provided standards for avionics equipment.

ARINC 429 is a specification, which defines how avionics equipment should communicate with each other.

ARINC 429 has been installed on most commercial transport aircraft.

Some aircraft are using alternate systems in an attempt to reduce the weight of wire needed.

The unidirectional ARINC 429 system provides high reliability at the cost of wire weight and limited data rates.

Military aircraft generally use a high-speed, bi-directional protocol MIL-STD-1553.

ARINC 429 also provides for transmission and acknowledgment of maintenance data and alphanumeric messages.
