On behalf of the International Civil Aviation Organization (ICAO), we have developed and operate SADIS.
Secure Aviation Data Information Service, SADIS
Here you will find information relating to the Secure Aviation Data Information Service - SADIS. These webpages are intended to provide an overview of the service, and complement the SADIS and WAFS information provided by the International Civil Aviation Organization (ICAO) on the Meteorological Panel web pages:
What is the SADIS?
SADIS is provided on behalf of, and under the oversight of the International Civil Aviation Organization (ICAO).
Its purpose is to make available meteorological data for international air navigation as specified in ICAO Annex 3 - Meteorological Service for International Air Navigation; and as described in the Regional Air Navigation Plans for the ICAO European, African, Middle East, North Atlantic, and Asia Pacific regions.
SADIS FTP is a data library. In itself it does not process/visualise data. It makes data available for extraction, processing and/or visualisation by end user systems. The end user systems may be SADIS Workstations. A list of providers can be found here: http://www.metoffice.gov.uk/aviation/sadis/manufacturers-full or end users may develop bespoke systems in-house.
Data available via the SADIS
As a service that is overseen by ICAO and funded by SADIS user States, it is a fundamental principle that all data distributed via SADIS must be agreed by the formal ICAO groups responsible for SADIS. Specifically, SADIS is tasked to make available data as specified in ICAO Annex 3. When endorsed by the ICAO groups overseeing SADIS, data in addition to the requirements of ICAO Annex 3 may also be made available.
Currently the primary groups with oversight of the day to day operational matters are the Meteorological Operations Group (WG-MOG) and the Meteorological Information Exchange Group (WG-MIE). Both of these groups work under the authority of the Meteorological Panel (METP). In addition, the Meteorological Information and Service Development (WG-MISD) and Meteorological Requirements and Integration (WG-MRI) groups have a more strategic and forward looking role, including development of the SADIS.
The SADIS user guide, (part 1 and part 2), provides technical descriptions of the service, and includes details of the data provided. The SADIS user guide can be accessed from http://www.icao.int/airnavigation/METP/MOG/Pages/SADIS.aspx
Who can access SADIS?
As a service provided on behalf of, and under the oversight of ICAO, all users of SADIS must have the prior (and ongoing) approval of their State Meteorological Authority. More information with regard to obtaining access to SADIS is provided here http://www.metoffice.gov.uk/aviation/sadis/procure.
How much does SADIS cost?
The provision of SADIS is funded through cost recovery. With the exception of States that are defined by the United Nations as Least Developed Countries (LDC), all user States (that is, any State that has users accessing SADIS from within its borders), are required to contribute to the costs of the service. The costs payable by each State are calculated annually by ICAO through the SADIS Cost Recovery Administrative Group (SCRAG). The precise mechanism and responsibilities of parties, are described in the SADIS Agreement:
All reports relating to the calculations of amounts due from each contributing State are made available by ICAO at this link (http://www.icao.int/sustainability/Joint-Financing/Pages/SCRAG-Reports.aspx). The calculations are agreed in November, and are usually published in December of any given year. Invoices are issued in January of the following year. It should be noted that States are responsible for payment of SADIS invoices, not individual users.
With regards to hardware/software, individual SADIS users will be required to procure and fund the necessary computer workstations/servers and software; internet connections; and ongoing support and maintenance (including regular hardware replacement and software upgrades). A list of SADIS Workstation providers is available from this link: http://www.metoffice.gov.uk/aviation/sadis/manufacturers-full. It is recommended that at least three providers are approached for quotations. Users should be as specific as possible when obtaining quotes. Consider the number of server locations, the number of clients, and any future expansion. Resilience and redundancy suitable to operations should be considered, including the use of uninterruptible power supplies.
How do I report problems with the SADIS Service?
In the first instance, check to see if you have received any SADIS administrative messages (NOUK10). These are used to inform users of operational matters relating to the service.
Users can request that the SADIS administrative messages are also sent to email addresses.
The last ten SADIS administrative messages are provided on a dedicated web page:
If the problem you are experiencing is not identified in a SADIS administrative message, then contact the 24/7 Service Desk:
By phone from the UK:
0370 900 0100 or 01392 885680
By phone from outside the UK:
+44 1392 885680
Please also copy the SADIS Manager (email@example.com) in to any emails.
If more convenient, the SADIS problem and query form can be used. This is especially useful if the problem relates to missing data.
