ATIS System
In principle, the ATIS system is designed to import data, mainly weather data, from local or remote data sources, and then transmit this information via radio or telephone to users performing aviation operations.
The system includes a device for automatically generating messages containing weather data from various data sources, such as AFTN, local or remote sensor packages, manual observations, and the national weather network. The generated messages can then be modified or supplemented by system users. Users can also create new messages to provide information about airport conditions or other phenomena.
The system features dual redundant functionality. This configuration uses two PCs installed on separate buses as “Server – A” and “Server – B,” which act as “hot standby” servers. This “Hot Switch” between the computers (PCs) ensures the continuity of information in the event of a failure, without compromising availability or data loss. The choice of which server is designated as the “hot” server or the “cold” server is made within the application. If an error occurs on “Server – A” PC (e.g., freezing, power failure, or displaying the wrong program), then “Server – B” PC will automatically become the “hot” server, and vice versa.
The dual audio subsystem consists of an industrial PC and an audio amplifier. It reads audio files from the ATIS servers and generates analog audio output data, which is fed into the amplifier and sent to the ATIS radio receiver.
ATIS Workstations will typically be used for viewing and editing messages.
Considering the above explanations, the dual redundant ATIS (Volmet) system is depicted in the Figure. Each system installation may differ in terms of the version or installed functionalities.In case of interest, please contact us.
