Summary of Defect:

In February 2000, ATNP/3 tasked WG3 to align the ASN.1 description of both D-ATIS and D-METAR reports in Doc 9705 with D-ATIS and D-METAR templates produced by OPLINKP and amendment 72 to ICAO Annex 3 produced by METLINKSG.

ATNP/3 Report Section 2.4.1: "The meeting was informed of some inconsistencies observed between range/resolution of some meteorological parameters contained in the Manuel of Technical Provisions for the Aeronautical Telecommunication Network (ATN) (Doc 9705) - Second Edition and some other ICAO documents. It was decided that a PDR should be immediately raised within the CCB to ascertain the problem, particularly with respect to backward compatibility, and to propose a solution which might be, in the short term, the issuance of a corrigendum to the document."

Assigned SME:                    	Sub-Volume II SME

Proposed SARPs amendment: 

Notes should be added in edition 2 and edition 3 to reference the applicable edition of Anex 3.

1/ In Edition 2: Add to section 2.4.4.2.1 (V1 D-ATIS ASN.1) the following note:

Note.- The structure, range and resolution of some meteorological parameters in this section are not fully in line with provisions of Annex 3 (up to and including Amendment 72). Those will be aligned in the next edition (3rd) of the document scheduled for publication in 2001.
