Guide to the provision of meteorological service for international helicopter operations

This publication was deemed obsolete by the Commission for Aeronautical Meteorology at its sixteenth session (CAeM-16) (24–27 July 2018) and has therefore been discontinued. This publication, which was developed jointly with ICAO, gives detailed guidance on what meteorological service should be provided for helicopter operations. It includes information on the operational requirements for observations, reports and forecasts for helicopter operations and gives examples of such support over high seas and mountainous terrain from WMO Members.
