1. INTRODUCTION

1.1 At ACP WG-M/16, Action 16-06 was agreed, to task Jean-Marc Vacher (France) with the consolidation of a draft Edition 2 for Doc 9880 Part II (AMHS), taking into account the various Amendment Proposals submitted with regards to this part of the Manual.

1.2 This paper aims at defining a completion process, within WG-M, to ensure that all relevant work items are taken into account while preparing this Draft Edition 2.

3. DISCUSSION

3.1 Amendment Proposals

3.1.1 Several Amendment Proposals for Doc 9880 Part II have been submitted to WG-M, as listed in the table below:

Table 1 – list of APs already addressed by WG-M

3.1.2 It is proposed to include the changes proposed in these APs in the draft Edition 2. The last item will be taken into account depending on the level of progress of WG-M regarding this detailed topic.

3.2 Changes needed as a follow-up to publication of Edition 1 of Doc 9880/AN-466 Part II

3.2.1 It appears that the Document 9880 AN/466 Part II version which is officially published by ICAO includes some editorial and paragraph numbering differences with the “advance Edition (unedited)” upon which the EUR AMHS Manual is primarily based. A detailed review has been performed, resulting in:

• A comprehensive identification of differences between the “advance Edition (unedited)” and the published Edition 1, which is provided for information as Appendix A to this paper. This information could be useful for ICAO Regions and States, for example when references are made in regional documents or manuals to Doc 9880. This identification includes an analysis of the impact for each difference;
• The observation that a relatively small number of mistakes were performed while editing the document. Most of these mistakes are considered editorial (for example, incorrect or missing update of cross-references internal to the document), however some changes also modified the meaning of the previous text. In such cases it is important that the initial meaning of the material should be restored, not to alter in an uncontrolled manner practices related to AMHS, which is currently in operation or being deployed on a worldwide basis.
• The table below provides the details of the changes which need to be performed to correct these mistakes.

Table 2 – list of changes needed following publication of Edition 1

3.2.2 It is proposed to include the changes proposed in Table 2 in the draft Edition 2.

3.3 Additional amendment proposals

3.3.1 While performing the detailed review mentioned above, a small number of required changes were identified, which were already needed in the advance Edition of Part IIB (unedited), for the following reasons:

• obsolete material (e.g. references to ATN Systems Management);
• material which was already incorrect in the advance edition.

1. The corresponding proposed changes are listed in Table 3, they are proposed for inclusion in Draft Edition 2.

4. ACTION BY THE MEETING

4.1 The working group is invited to:

• comment the proposed approach,
• confirm that the proposed work should be performed in preparation for the draft Edition 2 of Doc 9880/AN-466 Part II,
• define a process with the Secretariat to ensure that the published Edition 2 is aligned on the change proposals above.
