The "AUCS-Brik" consists of 3 elements: communication control block, information clicker of flight attendant, aircraft address block. The communication control block is an on-board digital computer (block B70-Bi-B on the frame), made on a single-processor scheme based on a serial processor of RISK 7000 class with possibility of rapid replacement (in stationary conditions) on a plug-compatible processor of a higher class and designed to automate the following tasks:
- control of apparatus components;
- organization and management of information exchange;
- transformation of information according to ARINC-618;
- interface between (while interacting with) the components of the apparatus inside the product with relative on-board systems and other electronic equipment;
By means of built-in modem MCHM is made:
- transformation of discrete signals into analog by the method of "Minimum frequency modulation" and back;
- interface with channel-forming equipment MV range.

The flight attendant information clicker is designed to enter data and display commercial information and provides:
- set and edit alphanumeric information;
- work in menu mode;
- exchange of information with communication control block (B70-Bi-B);
- indication of the information;
- enter formalized requests.

The aircraft address block is designed to store static data that does not change from flight to flight and issue this data to on-board systems.
