ARINC 573 is an avionics data bus standard developed by ARINC. It is mostly used with Flight Data Recorder that use 12bit words in continuous data stream encoded in Harvard biphase. [1] [2]

System bus single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent, and a control bus to determine its operation

A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and although popular in the 1970s and 1980s, more modern computers use a variety of separate buses adapted to more specific needs.

Aeronautical Radio, Incorporated (ARINC), established in 1929, was a major provider of transport communications and systems engineering solutions for eight industries: aviation, airports, defense, government, healthcare, networks, security, and transportation. ARINC had installed computer data networks in police cars and railroad cars and also maintains the standards for line-replaceable units.

Harvard biphase is a magnetic run length code for encoding magnetic tape. It is one of the formats employed in forming the digital bits of logic one and logic zero, along with non-return-to-zero (NRZ) and bipolar-return-to-zero (RZ) formats. Each bit in the Harvard biphase format undergoes change at its trailing edge and this transpires either from high to zero or zero to high independently of its value.

Avionics electronic systems used on aircraft, artificial satellites, and spacecraft

Avionics are the electronic systems used on aircraft, artificial satellites, and spacecraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. The term avionics is a portmanteau of the words aviation and electronics.

Neuro-linguistic programming (NLP) is an approach to communication, personal development, and psychotherapy created by Richard Bandler and John Grinder in California, United States in the 1970s. NLP's creators claim there is a connection between neurological processes (neuro-), language (linguistic) and behavioral patterns learned through experience (programming), and that these can be changed to achieve specific goals in life. Bandler and Grinder also claim that NLP methodology can "model" the skills of exceptional people, allowing anyone to acquire those skills. They claim as well that, often in a single session, NLP can treat problems such as phobias, depression, tic disorders, psychosomatic illnesses, near-sightedness, allergy, common cold, and learning disorders.

Minitab Statistics software

Minitab is a statistics package developed at the Pennsylvania State University by researchers Barbara F. Ryan, Thomas A. Ryan, Jr., and Brian L. Joiner in 1972. It began as a light version of OMNITAB 80, a statistical analysis program by NIST. Statistical analysis software such as Minitab automates calculations and the creation of graphs, allowing the user to focus more on the analysis of data and the interpretation of results. It is compatible with other Minitab, LLC software.

ACARS system for transmission of messages between aircraft and ground stations via radio or satellite

In aviation, ACARS is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite. The protocol was designed by ARINC and deployed in 1978, using the Telex format. More ACARS radio stations were added subsequently by SITA.

Avionics Full-Duplex Switched Ethernet (AFDX) is a data network, patented by international aircraft manufacturer Airbus, for safety-critical applications that utilizes dedicated bandwidth while providing deterministic quality of service (QoS). AFDX is a worldwide registered trademark by Airbus. The AFDX data network is based on Ethernet technology using commercial off-the-shelf (COTS) components. The AFDX data network is a specific implementation of ARINC Specification 664 Part 7, a profiled version of an IEEE 802.3 network per parts 1 & 2, which defines how commercial off-the-shelf networking components will be used for future generation Aircraft Data Networks (ADN). The six primary aspects of an AFDX data network include full duplex, redundancy, determinism, high speed performance, switched and profiled network.

ARINC 429, "Mark33 Digital Information Transfer System (DITS)," is also known as the Aeronautical Radio INC.

Gillham code

Gillham code is a zero-padded 12-bit binary code using a parallel nine- to eleven-wire interface, the Gillham interface, that is used to transmit uncorrected barometric altitude between an encoding altimeter or analog air data computer and a digital transponder. It is a modified form of a Gray code and is sometimes referred to simply as a "Gray code" in avionics literature.

Parkhead was a railway station in the east end of Glasgow. It was opened as Parkhead, by the North British Railway on 1 February 1871. It was renamed Parkhead North on 30 June 1952 by British Railways. This was to differentiate it from the nearby ex-Caledonian Railway Parkhead station on the former Glasgow Central Railway.

ARINC 424 or ARINC 424 Navigation System Data Base Standard is an international standard file format for aircraft navigation data maintained by Airlines Electronic Engineering Committee and published by Aeronautical Radio, Inc.. The ARINC 424 specifications are not a database, but a "standard for the preparation and transmission of data for assembly of airborne navigation system data bases".

ARINC 818: Avionics Digital Video Bus (ADVB) is a video interface and protocol standard developed for high bandwidth, low latency, uncompressed digital video transmission in avionics systems. The standard, which was released in January 2007, has been advanced by ARINC and the aerospace community to meet the stringent needs of high performance digital video. The specification was updated and ARINC 818-2 was released in December 2013, adding a number of new features, including link rates up to 32X fibre channel rates, channel-bonding, switching, field sequential color, bi-directional control, and data only links.

Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered to be a subset of information and communications technology (ICT). An information technology system is generally an information system, a communications system or, more specifically speaking, a computer system – including all hardware, software and peripheral equipment – operated by a limited group of users.

The ARINC 629 computer bus was introduced in May 1995 and is used on the Boeing 777, and Airbus aircraft. The ARINC 629 bus operates as a multiple-source, multiple-sink system; each terminal can transmit data to, and receive data from, every other terminal on the data bus. This allows much more freedom in the exchange of data between units in the avionics system. ARINC 629 has the ability to accommodate up to a total of 128 terminals on a data bus and supports a data rate of 2 Mbit/s.

ARINC 717 defines a digital flight data recorder, with its inputs and outputs. It replaces the older ARINC 573 characteristic, which was based on analog inputs. It allows for more data and real-time recording.
