Interoperability requirements specifying the needed transfer of data between transmitting aircraft and ground domains is provided in section 4 (INTEROP). This INTEROP specification is presented at a link-neutral (i.e. MASPS) level. Annex H provides traceability of Section 4 to specific 1090MHz Extended Squitter interoperability requirements. It was developed jointly with EUROCAE.
