This document specifies the minimum performance expected from e-reporting solutions for UAS and focuses on the e-reporting function meant to provide surveillance information generated by a UAS, i.e. either from the unmanned aircraft (UA) itself or its remote pilot station (RPS), at destination of other UAS and U-space services, these latter being also known as UAS Traffic Management (UTM) services in different regions of the world. Compliance with this standard is recommended as one means of assuring that the equipment will perform its intended function(s) satisfactorily under all conditions normally encountered in routine aeronautical operation. It is designed to ensure that equipment (either the unmanned aircraft system or a sub-set of hardware and /or software components implementing the function) compliant to it, will be able to demonstrate safety and suitability for operational use.
