Under certain
circumstances, as specified in AMC1 MET.TR.205(e)(3); otherwise, a resolution
of 100 ft is to be used.
(b) The explanations for the abbreviations can
be found in ICAO Doc 8400 ‘Procedures for Air Navigation Services — ICAO
Abbreviations and Codes (PANS-ABC)’.
EASA aviation regulations mandate specific ranges and resolutions for numerical data in local routine and special meteorological reports. These include runway direction, wind speed/direction, visibility, runway visual range, vertical visibility, cloud base height, air/dew-point temperature, and QNH/QFE. Standardized units and increments ensure consistent weather reporting for aviation safety.
