【国外标准】 Standard Specification for Performance for Weather Information Reports, Data Interfaces, and Weather Information Providers (WIPs)

1.1 In this specification, the standard of performance for weather information reports, analyses, and services performed by a weather information provider (WIP) in support of extensible traffic management (xTM) systems, unmanned aircraft systems (UAS) and vertical takeoff and landing (VTOL) systems operating from the surface to 5000 ft (1524 m) above ground level (AGL) are addressed.1.2 This specification does not define how to report a meteorological aerodrome report (METAR). This specification supports evolving international and the sovereign civil aviation authority (CAA) and air navigation service provider (ANSP) regulations.1.3 Relationship to International WIP Standards—One objective of this specification is to harmonize the standard across CAAs internationally to enable subject matter compatibility across standards developed by other standards development organizations (SDOs). The existence of multiple standards for the same subject matter can occur when a region’s regulator requires that a necessary standard be developed by a particular SDO. In these cases, ASTM International may seek to establish a cooperative arrangement with the applicable SDO to ensure consistency between the related standards.1.4 This specification provides an initial version to provide guidance to commercial aviation operations including, but not limited to, UAS and VTOL users, for weather measurements and analyses. Research and development activities will continue to inform and lead to modifications to this specification.1.5 This specification will not cover the standard of performance for weather forecasts.1.6 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
