ISO 21384-3:2026 Uncrewed Aircraft Systems - Operational Procedures

Basic Standard Profile

Full Title: Uncrewed Aircraft Systems - Operational Procedures

Edition: 1st edition, published 2026

Standard Positioning: Core document under the ISO 21384 UAS standard series, laying down unified best practices for global commercial drone operation management

ISO 21384-3:2026 – Uncrewed Aircraft Systems - Operational Procedures is an international standard developed by the International Organization for Standardization (ISO) to establish best practices for the safe and secure operation of commercial uncrewed aircraft systems (UAS). This document targets all commercial UAS operators, regardless of vehicle size, type, mission, or geographic location. It sets requirements for UAS operational procedures, encompassing external safety-critical services such as command and control (C2) links, risk management, personnel qualification, and maintenance. ISO 21384-3:2026 ensures compliance with global safety benchmarks and promotes harmonized UAS operations across various industries and jurisdictions.

Core Covered Topics

Safety and Security Requirements

The standard defines comprehensive requirements for safety management systems (SMS) and information security management systems (ISMS), covering all operational categories: open, specific, and certified. These include adopting safety policies, ongoing risk management, and robust security measures for UAS operations and supporting services.

C2 Link & External Services

Provision for the command and control (C2) link is emphasized as a safety-critical element, including requirements for C2 communications service providers (C2CSP). This ensures reliable connectivity between the remote pilot and the uncrewed aircraft.

Personnel and Roles

The standard outlines duties for key personnel such as the remote pilot in command (RPIC), compliance monitoring officer (COMO), safety officer (SAFO), fleet manager (FM), and visual observers (VO). Personnel must be sufficiently trained and qualified according to their responsibilities.

Flight and Operational Procedures

ISO 21384-3 specifies the framework for pre-flight planning, flight operations, emergency and contingency procedures, documentation, and logging. It also covers multiple aircraft operations, autonomous flights, and operational limitations.

Airspace and Regulatory Compliance

Operators are required to comply with airspace regulations, ensure aircraft identification and registration, and observe operational limits above certain flight levels.

Maintenance and Configuration

Essential guidelines are given for maintaining UAS hardware and software, managing updates, and documenting configuration changes.

Conflict Management

Operational procedures to prevent collisions and ensure separation in shared airspace are outlined, supporting safe integration of UAS in varied environments.

Primary Application Scenarios

Aerial Surveying and Mapping

Consistent operational procedures ensure high safety and legal compliance for geospatial data collection.

Logistics and Delivery

Guidelines for C2 link reliability, personnel training, and airspace rules help enable safe drone-based parcel delivery and supply chain operations.

Agriculture and Inspection

Operators conducting aerial spraying or infrastructure inspection can minimize risks and achieve regulatory alignment by adhering to this standard.

Public Safety and Emergency Response

Clear roles and procedures support safe use of UAS in search and rescue or disaster assessment scenarios.

Media and Filmmaking

ISO 21384-3 offers a robust structure for commercial drone video and photography missions, ensuring safety in populated and sensitive locations.

Organizations deploying UAS commercially can use ISO 21384-3:2026 to establish or audit operational protocols, mitigate risks, and demonstrate compliance to regulators, clients, and insurance providers.

Reference Standards

ISO 21384-4: Uncrewed Aircraft Systems - Vocabulary, establishes definitions and terminology to support UAS standardization.

ISO 23629-12: UAS Traffic Management (UTM) - Part 12: Requirements for UTM Service Providers, provides requirements for entities managing UAS traffic integration with other airspace users.

ISO 23665: Uncrewed Aircraft Systems - Training for Personnel Involved in UAS Operations, defines training and qualification requirements for UAS operators and supporting staff.

Closing Summary

By implementing ISO 21384-3:2026 alongside these related standards, organizations can achieve comprehensive, internationally recognized control over all aspects of UAS operations, supporting both safety-critical and commercial objectives.
