The standard also describes the Centralized Fault Display System. ARINC is a family of standards covering "data loading", commonly used for transferring software and data to or from avionics devices. It provides a standard approach for quality management of Test Procedure Generation within the commercial air transport industry. It is installed on the Boeing

ARINC is a multipart specification that defines an Ethernet data network for aircraft installations. These extensions to IEEE With its much higher data rates than older databus protocols ARINC is an attractive protocol for both new and retrofit aircraft systems. What is Space Shuttle? Two commonly used databuses were used on the Space Shuttle. The Multiplex Interface Adapter MIA databus is a command response protocol that uses bit words plus sync and parity.
Both protocols have a terminal address in the command word, but other bits are used differently. Words on the MIA databus are 24 bits long and have 5. There are no status words in the MIA protocol. The discretes control the timing, direction, and number of words on the serial databus.
The serial databus is bi-directional, but the discretes are always driven by the bus controller the PGSC and received by the remote terminal. The speed of the MDM bus is 1 megabits per second. Words have 16 bits, and messages can have up to 32 words. ARINC catalogs and compares many of the older avionics databus standards.
Protocols for the transmission of digital data were originally defined as part of the standardization of individual equipment characteristics. ARINC defines a system and then classifies these protocols according to their message, electrical, logical, and timing related elements.
Though there are some references to ARINC , the document was never approved so no equipment was developed using this protocol. ARINC is equivalent to the slow speed 64 words per second version of ARINC is an equipment characteristic for a Digital Air Data System DADS that provides essential air-data information for displays, autopilots, and other flight controls and instrumentation on commercial and transport type aircraft. ARINC defines a digital databus to distribute information to displays and other systems.
These protocols are very similar to MIL-STD except that their transmitted waveforms are controlled to look more like sine waves than a trapezoid. The reason is that there are fewer high frequency components in a rounded waveform, and therefore it reduces the possibility of electromagnetic interference to sensitive aircraft systems.
