ED Decision 2019/008/R
IN-FLIGHT WEATHER APPLICATIONS
āReliable sourcesā of data used by in-flight weather (IFW) applications are the organisations evaluated by the operator as being able to provide an appropriate level of data assurance in terms of accuracy and integrity. It is recommended that the following aspects be considered during that evaluation:
(a) The organisation should have a quality assurance system in place that covers the data source selection, acquisition/import, processing, validity period check, and the distribution phase;
(b) Any meteorological product provided by the organisation that is within the scope of meteorological information included in the flight documentation as defined in MET.TR.215(e) (Annex V (Definitions of terms used in Annexes II to XIII) to Commission Implementing Regulation (EU) 2016/1377) should originate only from authoritative sources or certified providers and should not be transformed or altered, except for the purpose of packaging the data in the correct format. The organisationās process should provide assurance that the integrity of those products is preserved in the data for use by the IFW application.
