Standard Guide for Testing Detect and Avoid Systems for Unmanned Aircraft Systems

Importancia y uso:

5.1 In this guide, test methodologies and data collection metrics for demonstrating adequate design and performance characteristics of DAA systems in accordance with Specification F3442/F3442M are outlined. DAA systems are essential for BVLOS flight operations for UAS as they enable the UAS to sense (detect) potential flight hazards, notify the PIC or autopilot (alert), and command the system to react such that it is not affected by the detected hazard (avoid).

5.2 This guide is designed to align with the development of requirements for DAA system performance in Specification F3442/F3442M. As Specification F3442/F3442M is revised, this guide will be updated to reflect the most current set of “shall” statements for which the users of this guide are responsible. Maintenance of this relationship enables users of Specification F3442/F3442M to connect system performance requirements to applicable guides clearly as described in this guide.

5.3 This guide exists to guide applicants toward a standardized methodology for validating their DAA system’s component functions and overall RRs. In this guide, a minimum set of procedures and considerations are defined for demonstrating that the applicant’s DAA system meets or exceeds the requirements of Specification F3442/F3442M. A standardized process for documenting the validation efforts is provided. Standardized reporting procedures ease the communication processes between applicants and the relevant regulator or authority and provide a common basis for documenting experimental results. In Section 13, considerations and report structure are provided while material in the appendixes give brief example reports for communicating compliance with Sections 8 – 12.

5.4 Users of this guide may seek to validate a single platform for a specific-use case and operational environment or a range of platforms that fall within a bounded use case and operational environment. This guide has been developed with the intent of being agnostic to either case.

5.5 Use of Tests and Modelling—In this guide, the use of physical testing and statistical modelling throughout are referenced. For any DAA system, several flight tests may need to occur to validate the models used for fast-time simulations, as described in Section 7. Within Section 8, a framework is referenced for verifying that the models used in simulation accurately represent the flight test efforts. As the cost of flight testing is normally a major concern for DAA system designers, applicants should follow the prescribed methods developed by industry experts. Once models of the various components of the DAA system are verified, then an applicant can determine performance metrics such as loss of well clear risk ratio LR and RR through numerous simulations and flight tests.
