Overview

ISO/TR 23267:2024 - Experiment results on test methods for detection and avoidance (DAA) systems for unmanned aircraft systems - is a Technical Report (first edition, April 2024) that documents experiments and test methods used to verify the safety and quality of onboard DAA systems for UAS. The report focuses on architectures using radar and optical sensors and provides modelling, equipment and flight test examples that demonstrate compliance with DAA performance requirements for non‑cooperative targets.

Key topics and technical requirements

Test scope
- Evaluation limited to onboard non‑cooperative DAA for UAS, including avoidance of manned aircraft and other UAS.
- Flight tests cover relative approach speeds up to 200 km/h (manned aircraft vs UAS) and 100 km/h (UAS vs UAS).
Three test applications
- Modelling and simulation: parameter setting and sensor modelling to evaluate collision‑avoidance performance. Example parameters include angle of intersection (360° at 15° intervals), route offsets, altitude gaps and number of targets. Evaluation items: radar detection, image recognition, avoidance and recovery.
- Equipment test: bench and ground verification of detection performance (radar, optical sensors) using high‑speed cameras, position measurement devices, anemometers and visibility meters.
- Flight test: in‑air verification following the 6‑step operational procedure of ISO 21384‑3 (some experiments merged steps), with hardware/software mapped by operational step (detection → recognition → manoeuvre → check → return → resume).
Performance evaluation items
- Radar detection accuracy, optical image recognition, autonomous manoeuvre execution (processing unit), and post‑manoeuvre recovery/check.
Documentation
- Detailed experiment results and setups are provided in Annexes A–E (modelling, equipment, and specific flight test scenarios).

Practical applications and users

Who benefits:

UAS manufacturers and system integrators validating onboard DAA systems (radar + optical).
Test laboratories and certification bodies developing test protocols for UAS safety cases.
Regulators and airspace managers assessing UAS operational safety in low‑altitude and urban environments.
Developers of sensor fusion and autonomy software seeking validated simulation and flight test patterns.

Typical uses:

Establishing verification programs for DAA capability.
Defining sensor and processing requirements to meet safety margins for obstacle and traffic avoidance.
Reproducing flight test scenarios (speeds, approach geometries, sensor suites) for compliance evidence.

Related standards

ISO 21384‑3 - referenced operational procedure (6‑step DAA workflow).
ISO 15964 - under development; expected to address standardization of DAA hardware/software components (sensors, computers, interfaces).

Keywords: ISO TR 23267:2024, detection and avoidance, DAA, unmanned aircraft systems, UAS DAA testing, modelling and simulation, flight test, radar and optical sensors, equipment test, ISO 21384-3.
