Full title and description

STB BS ISO 5491-2023 — Vertiports — Infrastructure and equipment for vertical take-off and landing (VTOL) of electrically powered cargo unmanned aircraft systems (UAS). This standard specifies requirements for the design, layout and essential equipment of small (type A / micro) vertiports intended to support electrically powered cargo UAS operations.

Abstract

This document defines the requirements for constructing a vertiport intended for vertical take-off and landing (VTOL) operations by electrically powered cargo unmanned aircraft systems (UAS). It is written for type A (micro) vertiports as classified in ISO 5015‑2 and covers physical layout, essential infrastructure and interfaces needed to operate and integrate such vertiports safely into UAS operations and UTM contexts.

Scope

The standard applies to the planning and construction of small (type A / micro) vertiports supporting electrically powered cargo UAS VTOL operations. It addresses the physical site and layout, required infrastructure elements and interfaces to traffic management systems, and provides baseline safety and operational requirements so that vertiports can be interoperable and integrated into urban or dedicated logistics networks. It does not attempt to cover manned VTOL passenger vertiports or larger vertiport classes beyond the defined type A (micro) scope.

Key topics and requirements

• Applicability to vertiports of type A (micro) as defined in ISO 5015‑2.
• Site layout and physical dimensions for take‑off and landing surfaces, approach/clearance zones and obstacle considerations.
• Surface markings, lighting and visual aids appropriate for small VTOL operations and low‑visibility conditions.
• Electrical supply and charging infrastructure requirements for electrically powered UAS, including power provisioning and basic safety provisions for charging operations.
• Communications and UTM/UTM‑service interfaces to enable traffic information exchange and coordination with UAS traffic management systems.
• Access control, signage, operational zones and separation between flight operations, handling/maintenance areas and public access.
• Emergency procedures, firefighting access and safety resilience measures tailored for small unmanned cargo operations.
• Environmental and site‑integration considerations (noise, local zoning/land use interface and sustainability aspects).

Typical use and users

Primary users include vertiport designers and engineers, infrastructure owners and operators, urban planners integrating UAS logistics nodes, UAS system integrators and operators (cargo delivery services), regulatory and certification bodies, emergency planners and equipment suppliers (charging systems, lighting, communications). The standard is used to define minimum design and equipment baselines for small cargo vertiports and to ensure interoperability with UTM services.

Related standards

Normative and related references commonly linked to ISO 5491 include ISO 5015‑2 (classification of vertiport types), ISO 21384‑4 (UAS vocabulary), and parts of the ISO 23629 series on UAS traffic management (for UTM functional structure and UTM service provider requirements). National adoptions or cross‑references (e.g., BS ISO versions) and ICAO guidance on vertiport/vertiport‑like infrastructure may also be relevant for implementers.

FAQ

Q: What is this standard?

A: ISO 5491:2023 is an international standard that specifies requirements for the infrastructure and equipment of small (type A/micro) vertiports used by electrically powered cargo unmanned aircraft systems (UAS).

Q: What does it cover?

A: It covers planning and construction requirements for vertiports supporting VTOL cargo UAS operations, including site layout, landing/take‑off areas, markings and lighting, electrical charging infrastructure basics, communications/UTM interfaces, access control and emergency considerations.

Q: Who typically uses it?

A: Designers and operators of vertiports, UAS cargo operators, equipment suppliers (charging, lighting, communications), airport/airfield authorities adapting small vertiport infrastructure, regulators and urban planners.

Q: Is it current or superseded?

A: ISO 5491:2023 is the current published edition (June 2023). ISO has work registered to revise and expand the document (ISO/DIS 5491) as part of a subsequent edition/DIS cycle; implementers should monitor the ISO work programme for updates.

Q: Is it part of a series?

A: It sits within a broader suite of UAS‑related ISO standards and airport/aircraft infrastructure activities (for example, ISO 5015 series for vertiport classification and ISO 23629 series for UTM). Users typically apply ISO 5491 together with those related documents.
