A-4) In Item 7, the presentation of the Amendment indicated item b) occurring before item a), as shown below, rather than the traditional presentation whereby a) normally precedes b). The rationale for this was unclear and could bestow undue priority on the use of registration markings as the radiotelephony callsign for each flight. The meeting confirmed its strong preference for ‘flight number callsigns’ and agreed that in the Asia/Pacific implementation, use of the designator for the aircraft operating agency followed by the flight number would take precedence.

The comment is accepted and items 7 a) and b) will be reordered in the published amendment.
