Introduction
To manage rapid growth of the unmanned aircraft system (UAS) operations, governments and
organizations have made efforts to develop UAS traffic management (UTM), such as UTM concept of
operations developed in USA, U-space concept of operations developed in Single European Sky ATM
Research (SESAR) and a common framework of UTM proposed by ICAO. According to these concepts and
perspectives, UTM service provider (USP) plays a core role in the UTM ecosystem. Hence, it is significant
to define the interfaces between USP and the users so that elements of exchanging information between
them for the implementation of UTM services can be clarified.
This document aims to help the sharing of information and interoperability between USP and the
users of UTM services and build a common cognition across states, regulators, industries and other
UTM stakeholders. It is in conformity with the structure of the ISO 23629 series, while making relevant
materials as references such as the documents of the American Society of Testing Materials (ASTM)
and operational concepts proposed by governments and organizations. This document only defines
the information exchanged in the interface under the structure in ISO 23629-5 and the requirement in
ISO 23629-12, while the protocol and data model used to realize the interface is not included.

5 Overview
5.1 UTM users
In light of the descriptions in ISO 23629-5 and ISO 23629-12, UTM users can be sorted into five main
categories: the operators, the aviation and airspace authority, the security and enforcement authority,
the public and the air traffic service provider (ATSP).
a) Operator. Encompassing both the UAS operator and the vertiport operator. The UAS operator
is defined as the person, organization or enterprise engaged in or offering to engage in a UAS
operation. The vertiport operator is defined as the person, organization or enterprise engaged in or
offering to engage in vertiport operations.
NOTE 1 The UAS operator and the vertiport operator can be different legal entities.
NOTE 2 See ISO 21384-4.
NOTE 3 Typically, three different information technology (IT) entities are under managerial control of
the UAS operator:
— the UA which, during the flight, can exchange digital data;
— the station of the remote pilot, which is also active and exchanges data with USP during the flight;
— the working position of the fleet manager, which can be always active and which exchanges data with
USP mainly in the flight preparation phase.
b) Aviation and airspace authority. The airspace regulatory body and the aviation authority exercising
oversight of all aviation activities, including operations of manned and unmanned aircraft,
related services, including air navigation services and air traffic management/services, as well as
aerodromes and vertiports.
NOTE 4 The oversight authority for civil activities is usually named the civil aviation administration
(CAA) and its tasks are mainly based on Annex 19 to the Chicago Convention.
NOTE 5 Based on Articles 1 and 2 of the Chicago Convention, states have sovereignty on the airspace
above their territory, including territorial waters. The organization of the airspace and its management
requires coordination between the CAA and corresponding military authorities.
NOTE 6 Involved public authorities can also include geozone managers, who can issue flight
authorisations, such as managers of critical infrastructures or municipalities.
c) Security and enforcement authority. The bodies responsible for national security and responding to
security incidents, as well as the law enforcement agencies (e.g. police) conducting investigations,
enforcing regulations and issuing sanctions, including in response to local complaints.
NOTE 7 The tasks of such authorities can include counter-UAS measures to neutralize unlawful UA.
d) Public. The public bodies obtaining UTM services, including people, organizations and enterprises.
e) ATSP. The organization responsible for providing air traffic services (ATS) in a designated volume
of coverage, within which the majority of air traffic constitutes manned aircraft.
5.2 Information exchange
Information exchanged between USP and the five main groups of UTM users includes, but is not limited
to, the following, some of which may be optional in practice:
a) Information for strategic service.
Traffic information for flight identification, tracking, de-confliction to ensure operation safety, including
UATI, MATI and AGI.
Supplemental information to support operation safety, including CGI, WI, PDI, EMI, CCI, NCI, AI and FPI.
b) Information for agent service.
USP provides agent service for RA from public and RR to the applicant.
USP provides agent service for OPA from operator and OPR to the applicant.
c) Information for guidance service.
USP provides tactical conflict alleviating actions to the operator, including OGI.
d) Information for support service.
USP provides support services to assist the operator in the operation plan, including traffic
accommodation capacity analysis, risk prediction analysis and emergency procedure plans.
Figure 1 shows the information exchange flows in the digital ecosystem in which UTM services are
actors. Dashed arrows depict interconnections between USP and the five different users defined in this
document. Solid arrows stand for other connections across the users. However, these connections are
out of the scope of this document; the presentation is only for the integrity of the ecosystem.
