ARINC 818 Protocol Technology
ARINC 818 builds upon the FC-AV protocol, which, like the newer standard, is an adaptation of fibre channel. While FC-AV is meant to support a wide range of industries, avionics vendors recognized the need for a unified standard specific to aeronautics applications. As a result, the ARINC Digital Video Committee was formed to define a standard that could be used in both military and commercial settings. A unidirectional adaptation of FC-AV was favored for its data-rate options, data integrity, and most importantly, its flexibility.
Officially released in 2007, ARINC 818 is a point-to-point, 8b/10b encoded serial protocol that has gained widespread industry support. By eliminating the need to create proprietary video systems in cockpits, ARINC 818 has reduced aviation design costs. What’s more, ARINC 818 has eliminated many of the complexities of FC-AV, such as the need for link initialization or flow control.
Some additional benefits of ARINC 818 include:
- Support for complex video implementations
- Multiplexing multiple video streams on one link
- The transmission of one stream over dual link
- Four defined timing classes
- Connects processors to a variety of display types
- Eliminates the need for handshaking
- Routing capabilities
- Error detection via ADVB packet and image CRC
These benefits make ARINC 818 a robust protocol, along with its reliable error detection capabilities that remain crucial in aerospace and military applications.
ARINC 818 Interface Applications
As today’s standard video transmission protocol for military and commercial aircraft, ARINC 818 serves as an interface solution for a wide range of use cases. Popular commercial cockpit suites including the Thales TopDeck and Rockwell Collins ProLine Fusion system leverage ARINC 818, which has accelerated the growth of the ARINC 818 protocol. Additionally, high-resolution sensor systems have begun utilizing ARINC 818, as its high-bandwidth capabilities are ideal for these applications.
Some of the most common ARINC 818 applications include:
- Primary flight displays
- Cockpit recorders
- Mapping systems
- Mission processors
- Video concentrators
- Enhanced vision systems
- Helmet-mounted displays
- Radar
- Cockpit simulators
- Infrared sensors
A protocol update known as ARINC 818-2 was released in 2013 and included an array of new features and capabilities. Notable new capabilities include methods to implement a return communication path on a single coaxial cable and support for compression and encryption. These enhancements have enabled new types of applications such as IR sensors, HUDs, enhanced vision systems and high-resolution cameras.
