Overview - ISO/TR 23310:2025 (UAS UTM study)
ISO/TR 23310:2025 is a Technical Report that studies functional and performance requirements for UAS traffic management (UTM) systems. Published as the first edition in 2025, it surveys international standards, national/regional implementations and operational frameworks to classify the actors, services, functions and data that make up UTM. The document also identifies safety, security and quality specifications for UTM services, with a particular focus on data management and referencing relevant work from other standard development organizations (SDOs).
Key technical topics and requirements
- Functional requirements: classification of UTM actors, services and functions; how actors interact with UTM subjects (software/IT entities) and operation support services. (Clause 4)
- Performance requirements: comprehensive performance expectations for data model transactions and for UTM services (availability, timeliness, continuity, integrity). (Clause 5)
- Safety and security: definitions and distinctions between safety-critical and safety-related UTM services, and associated quality and functional safety considerations.
- Data management: data models, data transactions, and Quality of Service (QoS) concepts for information exchange among UTM service providers (USPs), UTM users and other actors.
- Terminology and scope: standardized definitions (e.g., UTM, UTM service, USP, designated operational coverage, UTM subject, ground/air risk, reliability, confidentiality, integrity, availability). (Clauses 2–3)
- Actor/activity mapping: a catalog of digitally coupled actors (derived from regional ConOps) and mapping of actor activities to UTM services and data flows.
Practical applications - who uses this standard
ISO/TR 23310:2025 is practical for:
- UTM service providers and platform developers - to design interoperable service architectures, data models and API behavior.
- UAS operators and fleet managers - to understand service expectations (availability, timeliness, data integrity) when integrating UTM services into mission planning and execution.
- Regulators and air navigation authorities - to inform national UTM operational frameworks and designate operational coverage requirements.
- System integrators, safety and security engineers - to define functional safety, information security (confidentiality, integrity, availability) and reliability targets for UTM components.
- Standards bodies and researchers - to identify gaps, harmonize terminology and align national implementations with international practice.
