This document provides the minimum operational@ Safety and Performance Requirements (SPR) and Interoperability Requirements (INTEROP) for the implementation of the Automatic Dependent Surveillance-Broadcast Airport Surface Surveillance Application (ADS-B-APT). The ADS-B-APT application aims at enhancing aerodrome operations by adding ADS-B surveillance to a non-surveilled aerodrome and providing the controller with an appropriate graphical display to view the surveillance data. This document is intended to support the approval of all elements of the CNS/ATM system relating to the ADS-B-APT application.
