AMHS Web Terminal
AMHS WEB terminal – is a software application designed to handle the exchange of ATS (Air Traffic Services) messages via the Aeronautical Message Handling System (AMHS) network. The application operates on the with ICAO SARPs X.400 protocol, allows end users to connect to AMHS to send and receive ATS related messages. The application is developed taking into account the needs of ATS operators.
The terminal can also be used to send and receive free text messages, including attachments. The application is self-explanatory as built on the same principles as e-mail is operating, and therefore does not require special training of personnel to work with the AMHS WEB terminal.
The application provides a user-friendly HMI that includes convenient dialog forms and coloured tooltips popups. As the AMHS WEB terminal is developed on WEB technologies, it allows usage regardless of the operational system types in multi-user mode.
The application was developed in accordance with all spectrum of requirements of the ICAO Doc 9705 “Manual of technical provisions for the aeronautical telecommunication network (ATN), ICAO Doc 9880 PART III “Manual of detailed technical specification for the aeronautical telecommunication network (ATN) and European AMHS Target Profile as a complete solution for creating, sending and receiving ATS messages.

AMHS WEB terminal architecture and availability
The application has been developed using cutting edge technology in both software and hardware.The server part of AMHS WEB is capable of operating on Linux and Windows OS, as well as on hardware platforms from various manufacturers, which allows easy system integration into the customer’s infrastructure.
The client application runs on all popular Internet browsers, which allows to use the terminal from almost any device: PC, laptop, tablet and even a smartphone.
If the server is connected to the Internet, users can work with the AMHS WEB terminal from any physical location while having access to the Internet.
The AMHS WEB server application requires communication with the AMHS message repository using the P3 / P7 protocol over TCP / IP networks. It also requires a TCP / IP connection to connect clients.
