The ARINC 429 unit of transmission is a fixed-length 32-bit frame, which the standard refers to as a 'word'. The bits within an ARINC 429 word are serially identified from Bit Number 1 to Bit Number 32 [4] or simply Bit 1 to Bit 32. The fields and data structures of the ARINC 429 word are defined in terms of this numbering.
The ARINC 615 standard covers "data loading" over ARINC 429. ARINC 615A is a standard that covers a "data loading" protocol which can be used over various bus types such as Ethernet, CAN, and ARINC 664. ARINC 618 is a standard that covers a data transmission protocol called "Character Oriented Protocol". ARINC 619 is a standard that covers a ...
ARINC 429 operates in such a way that its single transmitter communicates in a point-to-point connection, thus requiring a significant amount of wiring which amounts to added weight. Another standard, ARINC 629 , introduced by Boeing for the 777 provided increased data speeds of up to 2 Mbit/s and allowing a maximum of 120 data terminals.
Most civilian aircraft use one of 3 serial buses: the Commercial Standard Digital Bus (CSDB), [1] ARINC 429, or AS-15531. The Commercial Standard Digital Bus is a two-wire asynchronous broadcast data transmission bus. Data is transmitted over an interconnecting cable by devices that comply with Electronic Industries Association (EIA) RS-422A.
The resolver position is sent to the converter which outputs the control signal to drive the CDI. For digital units, the desired position of the needle is transmitted via a serial ARINC 429 signal from the radio or GPS unit, allowing the CDI design to be independent of the receiver and by multiple receiver types.
