Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents.

Introduction

The implementation and operation of uncrewed aircraft system (UAS) traffic management (UTM) systems are progressing in many countries with the rapid development and penetration of UAS technology and usage. The International Civil Aviation Organization (ICAO) has published the fourth edition of its UTM guidance^[11^], which describes the principal guidelines and services for UTM implementation in each country, as well as gaps and issues related to UTM implementation.

ISO/TC 20/SC 16 has also been working on the definition of UTM based on UAS operations as defined in ISO 21384-3:2023^[1^]. It has developed standards such as ISO 23629-5:2023^[2^], ISO 23629-12:2022^[4^] and ISO 23629-9:2023^[5^], and other standards have been developed to clarify the composition of services and functions of the overall UTM system configuration.

The purpose of this document is to survey the current implementation status and requirements of UTM in different countries, classify possible services and functions not defined in existing standards, and identify the quality, safety and security requirements for each service or function.

Based on the different implementations of these UTMs in different countries and by different private UTM providers, this document identifies the classification of the services, stakeholders involved, functions encompassed and data handled, and examines the quality, safety and security requirements for these data to determine how much quality, safety and security each service requires, and security requirements for each service.

1 Scope

This document comprehensively examines information grounded in International Standards applicable to uncrewed aircraft system (UAS) traffic management (UTM) systems and the operational frameworks for UTM systems across various countries. It systematically catalogues the current entities involved in UTM systems, including the actors, services, functions and data. Additionally, it delineates the safety, security and quality specifications for these services, focusing on data management and referring, where appropriate, to standards developed by other standard development organizations (SDOs).
