Description
Assessment of ADS-B and Multilateration Surveillance to Support Air Traffic Services and Guidelines for Implementation
Automated Dependent Surveillance – Broadcast (ADS-B) and Multilateration (MLAT) are additional forms of electronic surveillance that may be used to support air traffic services in en-route and terminal area operations. ADS-B and MLAT may be introduced in areas that are either not served or are partially served by radar. Circular 326 contains the safety assessment carried out to conclude that ADS-B and MLAT may be used to provide a three (3) nautical mile separation minimum. Additionally, the document provides guidelines for the implementation of the minimum.
