Standing Committee on Services for Aviation (SC-AVI)


Jump to: Background | Governance | Purpose | Expertise | Membership | Duration and Modalities of Work | Outputs | Reports | Subsidiary Bodies | FileCloud Collaboration Platform


In 2020, through Resolution 1 (SERCOM-1), the Commission for Weather, Climate, Hydrological, Marine and Related Environmental Services and Applications (the 'Services Commission' or SERCOM) established, inter alia, a Standing Committee on Services for Aviation (SC-AVI) for the period 2020 to 2023.

In 2024, through Resolution 5.2/1 (SERCOM-3) [provisional resolution number], the Services Commission re-established SC-AVI for the period 2024 to 2027 with the terms of reference as given below. 


The SC-AVI is a subsidiary body of the Services Commission (SERCOM) and, accordingly, reports to SERCOM on a routine basis. Information on SERCOM is available here.

The SC-AVI itself comprises several subsidiary bodies in the form of expert teams (ETs), an advisory group (AG) and a task team (TT). Details on the nature, composition, activities and deliverables of the SC-AVI subsidiary bodies is available here.

The organizational chart for SC-AVI is as follows (click here open/enlarge in a new window):


The following sections provide information on the purpose, expertise, membership, duration, modalities of work and outputs of SC-AVI. In addition, access to the reports of SC-AVI is provided.

Any questions pertaining to SC-AVI, its parent or subsidiary bodies can be directed to the WMO Secretariat via email.

(a) To contribute to advancing the international standardization of meteorological services for international air navigation and to the provision of assistance to Members with aeronautical meteorological services to achieve compliance with those standards.

(b) To promote and facilitate the international sharing of implementation experience and good practice, the uptake and exchange of scientific and technological advancements, including pilot projects where appropriate, to meet evolving user requirements for high-quality, seamless, harmonized and cost-effective aeronautical meteorological information and services.

(c) To analyse the impacts of evolving technology, climate change and variability (including extreme weather and climate-related events), environmental sustainability targets, advances in scientific applications, and evolving international regulations on the provision of aeronautical meteorological services, and communicate these impacts to Members and aviation stakeholders concerned in a meaningful and proactive manner.

(d) To contribute to the long-term planning and development of enhanced aeronautical meteorological information and services in support of the future globally interoperable, harmonized air traffic management system.

(e) To promote the integration of meteorological information, i.e. observations, forecasts, warnings and alerts, into air traffic management systems and decision-making, including the transfer of new capabilities into operational and impact-based information services enabled by the science-for-services value cycle and projects such as an Aviation Research and Development Project (AvRDP).

(f) To sustain efficient and effective governance of aeronautical meteorological service provision by Members through the development and/or enhancement of guidance on appropriate cost recovery mechanisms for national and multinational services as well as advice on information and data exchange policies and good practices.

(g) To develop guidance, training material and other educational resources to assist Members in the implementation of the International Civil Aviation Organization (ICAO)/WMO requirements for quality management systems and compliance with the competency and qualification requirements of personnel providing meteorological service for international air navigation, with an emphasis on developing countries, least developed countries and small island developing States.

(h) To respond to Members’ aeronautical meteorology prioritized needs and support capacity development activities aiming to enhance the delivery of fit-for-purpose, high-quality, seamless, harmonized and cost-effective aeronautical meteorological services, particularly in developing countries, least developed countries and small island developing States.

(i) To enhance, through effective communication and outreach, global and regional collaboration and partnership in aeronautical meteorology amongst Members and their aeronautical service providers, aviation stakeholders and other partners, thereby helping to maintain an international community of practice.

(j) To provide advice, upon request, to the Infrastructure Commission (INFCOM) and its subsidiary bodies on the needs and requirements for enhanced observations, especially on the benefits of aircraft-based meteorological observations, including those derived through the WMO Aircraft Meteorological Data Relay programme, to improve services for aviation.


  1. The foregoing (a) to (j) will be addressed by the Standing Committee in close coordination, as and where necessary, with Members, RAs, technical commissions and/or the Research Board (and subsidiary bodies thereof) as well as ICAO and other partners.
  2. In the fulfilment of its mandate, the Standing Committee will remain cognisant of, as a minimum, the WMO Strategic Plan, the WMO Strategy for Service Delivery and its Implementation Plan (WMO-No. 1129) and the WMO Gender Action Plan.

  • Other technical experts may be invited, based on need, to serve as Observers on the Standing Committee, as determined by the Chair/co-vice-chairs of the Standing Committee in consultation with the president of SERCOM.


  1. To the extent practicable, the composition of SC-AVI should appropriately reflect regional and gender balance.
  2. Such other technical experts may include representatives of partner international organizations.

Until the next ordinary session of SERCOM that comes after an ordinary session of the World Meteorological Congress where, if required, the Standing Committee can be re-established at the discretion of SERCOM

Modalities of Work

  • Meetings
  • Conference calls
  • Correspondence including email exchanges and other appropriate online interactions

Reporting Requirements

When requested, the Standing Committee shall, through its Chair (or a co-Vice-Chair under authority delegated by the Chair), furnish the SERCOM Management Group with a progress report on the activities, outputs, priorities and risks of SC-AVI, including those that pertain to its subsidiary bodies as necessary, plus any matters that may require the advice or a decision of the SERCOM Management Group, including those that pertain to recommendations to be submitted to or arising from a SERCOM session.
