Aeronautical Message Handling System - WOW. ATS Message Handling System (AMHS) also known as Aeronautical Message Handling System is a standard for aeronautical ground- ground communications (e. NOTAM, Flight Plans or Meteorological Data) based on X.

It has been defined by the ICAO. ICAO Doc 9. 88. 0 Part II[1] defines two fundamental levels of service within the ATSMHS; Basic ATSMHS andthe Extended ATSMHS. Additionally, ICAO Doc 9. Part II, section 3. Extended ATSMHS. The Basic ATSMHS performs an operational role similar to the Aeronautical Fixed Telecommunication Network 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 inter- operate, 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 OSI model). 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. Interoperability.
In order to ensure unobstructed communication between the ANSPs, the European Air Navigation Planning Group (EANPG) of ICAO has defined 5. EUR AMHS Manual (V5. Appendix D, AMHS Conformance Tests), ASIA/PAC AMHS Manual (Annex B, AMHS Conformance and Compatibility Test, V2. ANSPs. Those tests are conducted using a test engine (AMHS Conformance Test Tool) and verify the conformance to the AMHS standard, which is defined in ICAO Doc 9. AN/4. 66: Manual on Detailed Technical Specifications for the Aeronautical Telecommunication Network (ATN) using ISO/OSI Standards and Protocols, Part II, First Edition - 2. In the context of Single European Sky (SES) initiative and the European regulation EC5.
EUROCONTROL developed a specification[3] to complement the regulation. The use of the specifications facilitates the demonstration of conformity to the essential requirements and regulatory provisions.
Implementations. In order to facilitate the transition from legacy protocols to this new standard EUROCONTROL launched a project called ECG (European or EATM Communications Gateway) to develop a gateway between AFTN and AMHS. The ECG was developed by the French manufacturer THALES and the German manufacturer COMSOFT.
Meanwhile, nearly all AMHS systems in Europe are derived from the ECG (see table below). Similar solutions are offered by Avitech Gmb.
H (Germany), Intelcan (Canada), TELEFONICA (Spain), IDS (Italy), Copperchase Ltd (UK),Radiocom (USA) working together with Skysoft Servicios S. A. (Argentina) and FREQUENTIS (Austria). The first AMHS system was implemented by Avitech Gmb. H (Germany) as a pioneer solution and went into operational use in 1.
German Military (Bundeswehr) and the first AMHS connection in Europe is in operational use since February 2. ANSPs of Germany and Spain.
Second in Europe were Bosnia and Herzegovina with Austria in 2. The first operational AMHS connection in the Middle East was established in 2.
United Arab Emirates (Abu Dhabi) and Oman. In the meantime Abu Dhabi has evolved as a nucleus for the introduction of AMHS in the Middle East, resulting in a coherent AMHS network of operational connection between UAE, Jordan, Egypt, Saudi Arabia, Oman and Qatar. Since 2. 01. 0 Jordan, Egypt and Saudi Arabia form the first operational AMHS triangle. In 2. 01. 2 the South American countries Peru and Colombia joined the circle of AMHS users while Asia has operated AMHS links between Hong Kong and Macao since 2. Singapore and India since 2. Interregional AMHS connections for improved traffic between ICAO regions could be established between the UK and the US in 2. UK and Singapore in the beginning of 2.
By end 2. 01. 1, ANSPs worldwide have replaced 1. AFTN connections by an AMHS link.
The up- to- date worldwide implementation status of AMHS is recorded in the ICAO COM Charts which are available from the AMC (ATS Messaging Management Centre) operated by EUROCONTROL. AMHS usage around the world.
