Overview
ISO 5491:2023 - "Vertiports - Infrastructure and equipment for vertical take-off and landing (VTOL) of electrically powered cargo unmanned aircraft systems (UAS)" specifies requirements for constructing type A (micro) vertiports used for electrically powered cargo UAS. The standard addresses both physical vertiport hardware and its connection to a Vertiport Information System (VIS), focusing on safety, sensing, communication and information exchange for automated, non‑visual logistics operations.
Key topics and technical requirements
- Scope and applicability
- Applies to micro vertiports as defined in ISO 5015-2 and intended mainly for logistics-based, automatic navigation (non‑visual flight).
- Vertiport design (manufacturer responsibilities)
- Functional requirements: obstacle detection, environmental monitoring (wind speed/direction, rainfall, temperature), GNSS signal strength measurement (recommendation for high‑accuracy methods such as RTK), bearing load and weathering resistance marking.
- Visibility and safety: lighting for visibility/night use, audible/visual approach announcements, fixed installation and impact mitigation.
- Communications: transmission of sensor parameters and static/dynamic information to the VIS; initial static information provisioning split between manufacturer-set and operator-set fields (e.g., fixed ID vs. IP/VIS settings).
- Operations: take‑off/landing permissibility decisions based on sensor data, surface preparation per external system (ES) directions.
- Optional/encouraged capability: battery charging/discharging or battery swapping support.
- Vertiport Information System (VIS) / Service provider responsibilities
- VIS acts as central manager of dynamic and static data, intermediating between vertiport and external systems (UTM, logistics platforms).
- Requirements for VIS design, communication, safety assurance, logging and user interfaces follow from the standard’s architecture.
- Safety, quality control and documentation
- System reliability, logs, instruction manuals and quality control processes are required to support safe vertiport operation.
Applications and users
- Primary applications
- Micro vertiports for last‑mile cargo delivery, automated logistics hubs, on‑demand small‑cargo VTOL operations.
- Who uses ISO 5491:2023
- Vertiport manufacturers and integrators
- Vertiport operators and VIS service providers
- UAS/UTM service providers, logistics companies and urban planners
- Regulators and certification bodies defining infrastructure requirements for cargo UAS
- Practical benefits include standardizing sensor and communication interfaces, improving safety for automated VTOL cargo operations, and enabling interoperability with UTM and external systems.
