ASIA/PAC the Guidance Document for AMHS Conformance Testing (AMHS Manual) Version 3.0 – September 2009 International Civil Aviation Organization. SP/1 International Civil Aviation Organization ATN/AMHS IMPLEMENTATION IN ASIA/PACIFIC REGION Sujan Kumar. Versions of Doc 9705 and EUROCONTROL AMHS Manual. Aeronautical Message Handling System - WOW. ATS Message Handling System (AMHS) also known as Aeronautical Message Handling System is a standard for aeronautical.

MUMBAI/INDIA, October 2009 On October 14th the first AMHS message could be exchanged between the Airports Authority of India (AAI) and the Civil Aviation Authority of Singapore (CAAS) in the course of conducting bilateral interoperability tests according to the ASIA/PAC AMHS Manual. Both participating administrations operate COMSOFTs mature messaging solution AIDA-NG with a track record of many successful trials and two operational AMHS links in Europe and the Middle East.

AIDA-NG handles AFTN as well as the AMHS networks in a closely integrated way and provides sophisticated means to manage the transition procedure from AFTN to AMHS safely.

Wow Fun Server Patch 4.3.4. ATS Message Handling System (AMHS) also known as Aeronautical Message Handling System is a standard for aeronautical ground-ground communications (e.g. For the transmission of, Flight Plans or Meteorological Data) based on profiles.

It has been defined by the. ICAO Doc 9880 Part II defines two fundamental levels of service within the ATSMHS; • Basic ATSMHS and • the Extended ATSMHS. Additionally, ICAO Doc 9880 (Part II, section 3.4) outlines different subsets of the Extended ATSMHS. The Basic ATSMHS performs an operational role similar to the with a few enhancements. The Extended ATSMHS provided enhanced features but includes the Basic level of service capability; in this way it is ensured that users with Extended Service capabilities can interoperate, at a basic level, with users having Basic Service capabilities and vice-versa. The ATSMHS is provided by a set of end systems, which collectively comprise the ATS Message Handling System. The systems co-operate to provide users (human or automated) with a data communication service.

The AMHS network is composed of interconnected ATS Message Servers that perform message switching at the application layer ( Layer 7 in the ). Direct users connect to ATS Message Servers by means of ATS Message User Agents. An ATS Message User Agent supporting the Extended level of service will use the Basic level of service to allow communication with users who only support the Basic ATSMHS.
