AOM focuses on designing a well-organized airspace structure that supports various types of air activities, different traffic volumes, and varying service levels and regulations, all aimed at improving the efficiency and safety of air travel. It is a vital part of Air Traffic Management (ATM) that involves the dynamic and integrated management of both air traffic and airspace. AOM ensures the safe, economical, and efficient flow of air traffic by providing necessary facilities and seamless services in coordination with all involved parties, including both airborne and ground-based operations.

        The main objective of AOM is to optimize the use of available airspace by dynamically sharing time and, when needed, separating airspace among different categories of users based on short-term needs. This process, known as Airspace Management (ASM), involves selecting and implementing airspace options to meet the needs of airspace users. The ultimate goal is to make the most efficient use of airspace based on actual needs and to avoid permanent airspace segregation whenever possible.

      ▶ Communication, Cooperation, and Coordination: These are critical elements for implementing FUA, ensuring that all parties collaborate effectively to manage airspace.

      ▶ National, High-Level Civil/Military Coordination: This is essential for a consistent and collaborative national airspace planning process.

         ASM is a method used to choose and implement airspace options to satisfy the needs of the Air Traffic Management (ATM) community. It is a planning activity aimed at maximizing the use of available airspace through dynamic time-sharing and sometimes segregating airspace among different categories of users based on short-term requirements.

         The main goal of ASM is to ensure the most efficient use of the airspace according to actual needs and, if possible, to avoid permanent airspace segregation. When it becomes necessary to separate different types of traffic by organizing the airspace (for instance, aircraft conducting military exercises), the size, shape, and time regulations of these areas are designed to minimize the impact on overall operations.

        The Regional Sub-Office AOM/ASM team collaborates closely with ICAO APAC Regional Office, and,where necessary, supports Headquarters' staff for all air navigation matters, and particularly withrespect to the implementation of Airspace Management in accordance with the Global Air NavigationPlan, the Asia/Pacific Seamless ANS Plan, the Aviation System Block Upgrades (ASBUs) framework andother related plans and policies, achieving results such as:

•         Participate in the definition of the Regional Sub-Office work programme in the fields of Airspace Management.
•          Identify challenges faced by States and propose action list to support the States.
•          Planning, organizing and managing assigned resources to ensure that they are being used efficiently to meet ICAO Strategic Objectives in a timely and efficient manner in accordance with agreed performance objectives.
•        Contribute to the APAC Regional Office’s policy development related to Airspace Management, by coordination with the ATM Section of the Regional Office.
•         Assess the implementation status of airspace management in APAC States.
•         Support States in the development and implementation of airspace management.
•         Organize seminars/workshops to promote international practices on airspace management implementation and airspace simulation.
•         Organize other activities aimed at achieving the most efficient use of airspace, or addressing specific implementation challenges.
