- How to decode ARINC 429 data? - Aviation Stack Exchange
ARINC 429 is a defined standard that not only describes the packet structure (32 bits) but also the data formats for different labels depending on the equipment ID To know how to properly decode an ARINC 429 label you need to know the Equipment ID, which can then be used to look up the meaning of a specific label
- What is the difference between CAN and ARINC?
A Boeing 787 incorporates ARINC 664 for the main network with some subsystems on ARINC 429 and a number of sensors and cockpit controls on CAN (ARINC 825) Almost all the switches on the B787 overhead panel go through a couple CAN busses, eliminating dozens of wire runs There's also a significant difference in cost $\endgroup$ –
- aircraft design - Why are ARINC labels are transmitted LSB first . . .
ARINC 429 transceivers have been implemented with 32-bit shift registers Parallel access to that shift register is often octet-oriented As such, the bit order of the octet access is the bit order of the accessing device, which is usually LSB 0; and serial transmission is arranged such that the least significant bit of each octet is
- Does ARINC-664 (AFDX) supersedes both ARINC-429 and ARINC-629?
Wondering if ARINC-664 (and ARINC-629) have backwards combability with ARINC-429 I realize -664 uses Ethernet while -429 is implemented using a two-wire data bus However, wanted to see if any of the 32-bit ARINC-429 are "ported" upwards
- How are the BNR and BCD data formats identified in an ARINC-429 message?
The receiver has to be programmed It's important to remember that A429 is a unidirectional hard-wired bus with a single transmitter and multiple receivers Each connection is physically unique and the reason for all the pin-out diagrams and bus definitions in the ARINC Characteristics
- Inconsistent ARINC 717 Barker Codes - Aviation Stack Exchange
Devices in the aircraft use ARINC protocols as the way they communicate with each other, and to communicate with ground services There’s over 100 different ARINC standards and 717 establishes the data format for flight data recording
- arinc 429 - Why use different data bus for civil and military avionics . . .
The primary reason for moving away from ARINC-429 is that it is a single transmitter multiple receiver architecture This results in a large amount of physical wire That adds weight and requires maintenance A bus such as ARINC-664, which is based on Ethernet, can significantly reduce wire
- avionics - What is the encoding difference between ARINC 429 BNR and . . .
I think I have an understanding of the differences between the types of ARINC word formats, but would just like to get some input to see if my understanding is correct In the ARINC 429 specification, it is discussed that there are some differences in how messages are handled between the two formats Data Field
