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.
[11]
The International Civil Aviation Organization (ICAO) has published the fourth edition of its UTM guidance ,
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
[1] [2] [4]
ISO 21384-3:2023 . It has developed standards such as ISO 23629-5:2023 , ISO 23629-12:2022 and
[5]
ISO 23629-9:2023 , 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.

4 Functional requirements of UTM systems
4.1 General
This clause classifies the functional requirements of UTMs based on the concepts, design, and regulations
of UA operational management as defined by international organizations such as ICAO and ISO, as well as
regional and national standards and regulations.
This document considers:
[11] [1] [2] [4] [5]
— ICAO UTM Framework , ISO 21384-3 , ISO 23629-5 , ISO 23629-12 and ISO 23629-9 ;
[13] [14][15]
— several international, regional and national standard documents such as JARUS , ASTM and
[16][17] [19]
EUROCAE [18] ;
[20]to[33] [20]
— regional and national concept of operation documents , including GUTMA’s position paper ,
[21] [22]
SESAR U-space ConOps and FAA UTM ConOps ;
[34]to[40]
— regional and national regulations ;
[41]
— practical implementations such as InterUSS .
This clause organizes the functional requirements of the UTM system described in these documents,
emphasizing the classification of actors, activities, services, functions as an information system, and data
models. In particular, the analysis and classification focus on the correlation between actors and activities
and how services function as information systems concerning the data model.
4.2 Actors on UTM systems
The actors in UTM differ according to the perspective of each document: ICAO has a perspective closer
[4]
to aviation authorities and air traffic control, ISO 23629-12 has a perspective centred on UTM service
[5]
providers, and ISO 23629-9 defines the six actors in the framework of the parts of the UTM system that
contribute to the exchange of data. Table 1 lists 30 digitally coupled actors to the UTM system, derived from
[21]
national documents, mainly SESAR U-space ConOps .
Table 2 shows the results of the actor activities inferred and extracted from each document. Ten actor
activities are tied to how the actors use the UTM system.
The 32 actors noted in Table 1 are classified using the 10 activities shown in Table 2, and similarities are
summarized into 10 actors in Table 3. A table of relationships between the 10 summarized actors and the 10
activities is also presented in Table 4.

personnel, organizations and products, and enforcement activities.
2 Airspace AC A state function delegated by a country or region to establish UAS
coordinator airspace geozones, including facilitation, restrictions, and
determination of UTM services, in coordination with relevant
authorities and entities. The AC sometimes functions as the CAA or
another State authority (e.g. civil-military committee for airspace
management).

4.3 Services on UTM systems
The classification of services is based on:
— the relationship between the provider and receiver of the information presented by the service;
— when it is addressed to the operational process of the uncrewed aircraft (before, during or after
operation).
[11] [4]
ICAO defines 12 primary services in the ICAO UTM Framework . ISO 23629-12:2022 defines three main
types of services: safety-critical UTM services, safety-related UTM services and operation-support services.

Table 5 shows the 30 UTM services given in ISO 23629-12:2022 , Annexes A, B and C.

On the other hand, ISO 23629-5:2023 , SESAR U-space ConOps and other documents propose additional
services. Table 6 describes additional UTM services proposed by other standards and documents.
[2]
ISO 23629-5 provides six main functional categories of the UTM functional structure and SESAR U-space
[21] [11]
ConOps presents eight main types of services. The ICAO UTM Framework defines 12 services and
presents them as UTM operational management functionality requirements. From these functional and
service classifications, Table 7 presents the UTM services listed in Tables 5 and 6 into nine medium categories,
[2] [11]
and Table 8 presents the correspondence table between ISO 23629-5 , ICAO UTM Framework , SESAR
[21]
U-space ConOps and the nine UTM services defined in this document. Table 8 shows the correspondence
between the medium categories.

management DOC at tactical level (after take-off), based on real time critical
service information provided by other UTM services, such as CMS,
NIS and TRS.

formation and distributing this information to authorized
UTM users, including operators of aerodromes, vertiports
or other facilities supporting take-off/launch or landing/
recovery of UAS, or other UTM SPs, for the purpose of
maintaining safe mutual distances.
10 Traffic information TIS Providing the UAS operator with information on other Safety-
service known or observed crewed or uncrewed air traffic that critical
are potentially in proximity to the position or intended
route of the UA flight to alert and help the UAS remote
crew to avoid a collision.
