ASM Support Systems facilitate the exchange of ASM data between ASM Support Systems used by different stakeholders.
This information exchange supports the optimisation of ASM operations from the beginning of the airspace planning cycle. Furthermore, users from one state could reserve airspace structures managed by another state using their national ASM Support System. The traceability of the requirements specified in this specification document to information exchange requirements, defined in Annex 12 of the ASM Handbook, can be found in Annex B of this document. These information exchange requirements have been used in the identification for the service interfaces defined in this specification document.
