This makes it possible to determine an element just by its aricn in the frame, and the parameters can transmit data in their chronological order without interruptions and separations.

Each individual fraction is verified via an 8-bit specificaton and additionally, it also contains a payload between 18 bits and 19 bits. However, when the voltage value is at logical ONE, this value is converted during the bit width. Often, the plug-in location is not sufficient as identification, so that a table must be used for decoding. As such, with regard to low data security, the deficiencies of the precursor model have been eliminated thanks to the ARINC and data can 771 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.

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.

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.

ARINC Monitor Utility

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. A frame has a total specificatkon four subframes, which are then assigned each second of the four seconds of recorded life time. The subframes then are the subdivisions of this frame. The remaining parameters then can be installed according to a scheme defined by a specified pattern. With this, a procedure is used for coding as a basis.

The subframes also always differ in their first parameter, which is used for the purpose of identification. The collected data includes information concerning the condition spwcification the devices.

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

Known of in the field of aeronautics for some while, the ARINC protocols are a means that can be deployed in many ways. Starting phase of the ARINC – after installing the digital flight data acquisition unit, this unit receives information from the different components in the aircraft. Each individual parameter of the set to be transmitted holds 12 bits of stored payload.

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.

This value can be obtained over the entire bit width.

These data elements are recorded as so-called parameters. Final phase of the ARINC – a set of parameters is only considered as having been transmitted completely when one frame, i. As a rule a whole 25 hours of the life time of an aircraft are recorded and stored.

This data can also provide information regarding the altitude, the current and average velocity and the position of the rudder. A recording of four seconds of the life of an aircraft is called a frame. Afterwards this process can start again. The digital flight data acquisition unit buffers the data, thus converting them to frames and subframes.

This data bundle then reaches the DFDR only. 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.
