SATELLITE DISTRIBUTION SYSTEM OPERATIONS GROUP (SADISOPSG)

TWELFTH MEETING

Bangkok, Thailand, 4 to 6 June 2007

IATA STATISTICS OF AOP AERODROMES IN SUG ANNEX 1

(Presented by the International Civil Aviation Organization)

1.  INTRODUCTION

1.1  The SADIS User Guide Annex 1 list all aerodromes for which OPMET data are required to be distributed. It contains requirements for AOP aerodromes as well as for Non-AOP aerodromes.

1.2  It was agreed that all aerodromes listed in an AOP table of the ICAO regions are automatically inserted in SUG Annex 1. This implies also that the State concerned is requested to provide OPMET data for that aerodrome. Some States indicated that for some AOP aerodromes no OPMET data is issued.

1.3  All users do expect that as a minimum all available OPMET data for AOP aerodromes will be distributed on SADIS. It is recognised that, for small general aviation aerodromes, a State may decide not to issue OPMET data, as indicated in the regional ANP.

2.  Discussion

2.1  The following table gives a brief overview about the current number of available OPMET data on SADIS. This statistic is based on information about AOP tables dated September 2006, SUG Annex 1 dated September 2006 and an IATA monitoring of the SADIS broadcast dated April, 03rd 2006. It might be that due to changes in one of the mentioned tables during the last month, some numbers have changed.

2.2  The above table shows that 1045 (-22) (80,8%, +1,6%) AOP aerodromes do provide OPMET data as requested. All other AOP aerodromes do not meet the users requirements (19,2%.). 92 (+-17) (7,1%, +1,0%) AOP aerodromes do not provide all OPMET data while 112 (8,7%) do not distribute any data. For 45 (-6) (3,5%, +0,1%) AOP aerodromes it is indicated that no OPMET data will be issued. Detailed information related to the availability of OPMET information on the SADIS broadcast is provided in the appendix as follows:

a)  Table 1, all AOP aerodromes are listed for which no OPMET data could be found;

b)  Table 2, all AOP aerodromes are listed for which only SA could be found;

c)  Table 3, all AOP aerodromes are listed for which only FC and FT could be found;

d)  Table 4, all AOP aerodromes are listed for which only FC could be found; and

e)  Table 5, all AOP aerodromes are listed for which only FT could be found.

2.3  IATA is requesting some efforts by the group to improve the availability of OPMET data for AOP aerodromes in the near future. The group may wish to formulate the following conclusion.

3.  ACTION BY THE SADISOPSG

3.1  The SADISOPSG is invited to:

a)  note the information presented in this paper; and

b)  decide on the draft conclusion proposed for the group’s consideration.
