AeM Series, 07. Outcomes of the 2021 Global Survey on Gender Equality in Aeronautical Meteorology
The 2021 global survey on gender equality in aeronautical meteorology was conducted by the Standing Committee on Services for Aviation (SC-AVI) between June and August 2021. The objective of the survey was to collate information on respondents’ experience regarding gender equality and empowerment of women in the aeronautical meteorology domain, particularly at the national level. The survey also sought to obtain additional insight on the policies, action plans and/or guidelines pertaining to gender equality in aeronautical meteorology that may exist in the workplace.
The most salient in ...
