ISO 23629-12:2022 UAS トラフィック管理 (UTM) — Part 12: UTM サービス プロバイダーの要件 | ページ 6

3.1

constituent

tangible objects such as hardware and intangible objects such as software upon which the provision of UTM services (3.9) depends

Note 1 to entry: The definition is adapted from Reference [4].

3.2

designated operational coverage

DOC

geographic volume of airspace within which an UTM service (3.9) is available in compliance with designation by competent authorities if applicable, with sufficient performance including availability, continuity, integrity and timeliness and, if applicable, with sufficient radio signal quality and protection from other users of the electromagnetic spectrum

Note 1 to entry: The definition is adapted from Reference [5].

3.3

in-time system-wide safety assurance

ISSA

safety net utilising system-wide information to provide alerting and to trigger mitigation strategies in time to address emerging risks

Note 1 to entry: It is part of proactive safety management.

Note 2 to entry: The definition is adapted from Reference [6].

3.4

operation support service

web-based tools and information provided by a service provider (SP) to an UAS operator or its staff, to support safe and efficient planning and execution of a flight mission, as well as post-flight activities

Note 1 to entry: Operation support services cover a time span much wider than UTM services (3.9) . Although they support UAS operations, they are neither traffic management nor air navigation services.

3.5

safety-critical UTM service

UTM service (3.9) providing functions that, if lost or degraded, or as a result of incorrect or inadvertent operation, could result in catastrophic consequences

[SOURCE:ISO 14620-1:2018, 3.1.17, modified — The term has been changed from"safety critical function";"function" has been changed to"UTM service providing functions";"or critical" has been removed before"consequences". See Reference [7].]

3.6

safety-related UTM service

UTM service (3.9) providing functions that have the potential to contribute to the violation of or achievement of a safety goal, but whose loss of degradation would not in itself produce catastrophic consequences

[SOURCE:ISO 26262-1:2018, 3.1.17, modified — The term has been changed from"safety-related function";"function" has been changed to"UTM service providing functions";"but whose loss of degradation would not in itself produce catastrophic consequences" has been added at the end. See Reference [8].]

3.7

UAS traffic management

UTM

set of traffic management and air navigation services (ANS) aiming at safe, secure and efficient integration of multiple manned and unmanned aircraft flying inside the respective DOC (3.2) of each service

Note 1 to entry: The definition is adapted from Reference [9] and harmonised with the one in Reference [10].

Note 2 to entry: In accordance with Reference [10], UTM services (3.9) initiate when the UAS operator files a request for clearance to enter airspace and terminates when the UA reaches the parking position, the primary propulsion systems are switched off and the operational plan is closed.

[SOURCE:ISO 23629-7:2021, 3.11, modified — Notes 1 and 2 to entry have been added.]

3.8

UTM actor

role played by an UTM user (3.12) or UTM SP (3.10) or provider of operation support (3.4) that interacts with the UTM subject (3.11)

Note 1 to entry: An actor models a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data), but which is external to the subject.

Note 2 to entry: The definition is adapted from ISO/IEC 19501 ^[11].

3.9

UTM service

result of at least one activity necessarily performed at the interface between the UTM SP) (3.10) or operation support (3.4) provider and the UTM user (3.12) , which consist in the provisions of digital data and information

Note 1 to entry: The definition is adapted from ISO/IEC 19501 ^[11].

Note 2 to entry: To provide the service, the SP uses facilities, trained and qualified staff, organizational procedures as well as systems and devices executing one or more functions.

3.10

UTM service provider

UTM SP

organization playing the role of an UTM actor (3.8) which provides, normally in exchange of a fee, digital data and information to UTM users (3.12) , which may choose to take advantage from the offered service

Note 1 to entry: The definition is adapted from ISO/IEC 19501 ^[11].

3.11

UTM subject

information technology (IT) entity (including subsystem, component, or even class) representing a software system residing on a physical system or platform, supporting the exchange of digital data and information among several UTM users (3.12) and several UTM SPs (3.10) or operation support SPs (3.4) , and to which a set of use cases applies in the UTM (3.7) context

Note 1 to entry: The definition is adapted from ISO/IEC 19501 ^[11].

Note 2 to entry: Utilisation of at least one UTM subject is a necessary technical enabler for any UTM service (3.9) , but it is not a service in itself.

3.12

UTM user

organization or system, which uses digital data and information offered by an UTM SP (3.10) to fulfil their mission that is neither an UTM SP nor an operations support SPs (3.4)

Note 1 to entry: The definition is adapted from ISO/IEC 19501 ^[11].

Note 2 to entry: The UTM user is an UTM actor (3.8) .

Note 3 to entry: In addition to UAS operators, a non-exhaustive list of UTM users includes public authorities and civil aviation authorities, law enforcement agencies (for safety, security and privacy), search and rescue, fire brigades and other emergency services, providers of ATM/ANS to manned aviation, operators of aerodromes, vertiports or other facilities supporting take-off/launch or landing/recovery of UAS, UAS manufacturers and owners, insurance companies, ISO certifying bodies and qualified entities, training organizations, general public.
