A frame has a total of four subframes, which are then assigned each second of the four seconds of recorded life time. However, when the voltage value is at logical ONE, this value is converted during the bit width. The digital flight data acquisition unit buffers the data, thus converting them to frames and subframes.

The subframes then are specifocation subdivisions of this frame.

This value can be obtained over the entire bit width. This makes it possible to determine an element just by its position in the frame, and the parameters can transmit data in their chronological order without interruptions and separations. In former times, when ARINC was not yet on the market, aircraft mostly recorded only up to 64 parameters, but since the introduction of the digital flight recorders, the average is parameters.

Often, the plug-in location is not sufficient as identification, so that a table must be used for decoding.

Each individual fraction is verified via an 8-bit identifier and additionally, it also contains a payload between 18 bits and 19 bits. This data can also provide information regarding the altitude, the current and average velocity and the position of the rudder. As a rule a whole 25 hours of the life time of an aircraft are recorded and stored. They make it possible to combine the many different components in the system to form an assembly that works effectively, in which it is possible to optimally secure transmitted and received data between two or more devices and as a result, ensure smooth running of the processes.

ARINC – A protocol that defines a standard of data communication – KUNBUS GMBH

The remaining parameters then can be installed according to a scheme defined by a specified pattern. At this point of the ARINC protocol, the bits which regulate identification and synchronization are no longer needed, as the subframes always have the same construction.

In comparison, parameters must always be recorded for an aircraft in the United States of America, and in the case of the Airbus A, the largest commercial aircraft that produced in serial production, one recording is made up of parameters.

However, the ARINC is characterised as a significant point in this development, starting from which, the standard has sepcification raised and optimized many times over.

A recording of four seconds of the life of sepcification aircraft is called a frame. The collected data includes information concerning the condition of the devices.

Known of in the field of aeronautics for some while, the ARINC protocols are a means that can be deployed in many ways. With this, a procedure is used for coding as a basis. These data elements are recorded as so-called parameters. This data bundle then reaches the Specitication only.

As such, with regard to low data security, the deficiencies of the precursor model have been eliminated thanks to the ARINC and data can now be recorded in real-time, so that meaningful results are available to aviation and there is an option for technological development to a higher level.

Here, the DFDAU assumes the position of the computer and the transmission point, as the different data are collected, combined, and transformed into the format of the ARINC protocol on these system components. Afterwards this process can start again.

Final phase of the 7177 – a set of parameters is only considered as having been transmitted completely when one frame, i. Each individual parameter of the set to be transmitted holds 12 bits of stored payload.

Starting phase of the ARINC – after installing the digital flight data acquisition unit, this unit receives information specivication the different components in the aircraft. The subframes also always differ in their first parameter, which is used for the purpose of identification.

However, not every parameter is actually needed in each transmission, so that the parameters considered as less important in the system are only used and transmitted in each second or fourth parameter.
