Microwave Landing System (MLS) Multiple System Design Interoperability Interface Control Report.

摘要

This document standardizes the communications interface between two Microwave Landing Systems one each installed at opposite runway ends and which are each of a different design/manufacture. The interface requirements include the physical, data link control and application level requirements and are established to promote the interoperability of the systems. Functions specified include the establishment and termination of transmissions, and the structure, format, and encoding of messages and commands for transmission. The logical units and datapoints for all Microwave Landing System monitored parameters and status parameters are addressed. Additionally, a synchronization function is established to provide a timing reference to assure interference free transmission of the signals-in-space from each of the two MLSs. The operation, encoding and format of the synchronization function is provided.
