Full title and description

ISO 5286:2023 — Flight performance of civil small and light fixed-wing unmanned aircraft systems (UAS) — Test methods. This International Standard defines standardized test requirements and procedures for verifying declared flight performance characteristics of small and light fixed‑wing UAS to support consistent evaluation by manufacturers, test laboratories and authorities.

Abstract

This document specifies the test requirements and methods for verifying the specified flight performance items of civil fixed‑wing unmanned aircraft systems (UAS). It applies to civil small and light fixed‑wing UAS (maximum take‑off mass levels I through V as defined in ISO 21895) and provides guidance on test planning, instrumentation, test conditions, and data reporting needed to confirm performance claims.

Scope

ISO 5286:2023 is applicable to civil small and light fixed‑wing unmanned aircraft systems whose maximum take‑off mass (MTOM) falls within MTOM levels I–V as classified in ISO 21895. The standard covers the definition of flight performance items to be tested, requirements for test planning and instrumentation, test conditions and envelopes (mass/center‑of‑gravity), data acquisition and processing, and reporting of results to demonstrate conformity with declared performance. It is focused on fixed‑wing UAs and does not specify methods for rotary‑wing (multicopter) flight stability tests.

Key topics and requirements

• Definition of flight performance items to be verified (examples: take‑off and landing performance, climb rates, cruise and stall speeds, range/endurance as declared by the manufacturer).
• Test planning and documentation: test basis, objectives, environmental and operational acceptance criteria, instrumentation and calibration requirements.
• Test article preparation: conditions of mass and centre‑of‑gravity envelopes, payload configurations and pre‑test checks.
• Instrumentation, measurement accuracy and calibration traceability for speed, altitude, time, position and other measured parameters.
• Environmental conditions and allowed variation (wind, temperature, pressure) and procedures for documenting their effect on results.
• Data processing, analysis methods, uncertainty treatment and standardized reporting templates to support repeatable evaluation.
• Pass/fail or conformity criteria for declared performance claims and recommendations for test record retention.

Typical use and users

Primary users are UAS manufacturers, independent testing laboratories, conformity assessment bodies, certification and regulatory authorities, research institutions and developers validating flight performance. The standard is used when verifying manufacturer's declared performance for product specification sheets, supporting regulatory compliance dossiers, or for internal verification during design and production testing.

Related standards

Standards commonly referenced alongside ISO 5286:2023 include ISO 21895 (classification of UAS by maximum take‑off mass levels), the ISO 21384 series (general UAS specifications and components), and other ISO test or evaluation documents for UAS flight characteristics and stability. Regional regulatory guidance (for example, EASA and national aviation authorities) may be used together with ISO 5286 for operational and certification contexts.
