US non-profit technical guidance organisation RTCA has released updates for UAS safety standards
DO-365C Change 1 and DO-366B relate to detect and avoid (DAA) systems and air-to-air (ATAR) traffic surveillance.
DO-365C Change 1 aims to enhance DAA standards for uncrewed aerial systems (UAS) operations in controlled and extended airspace, ensuring safer integration into the National Airspace System.
DO-366B introduces a new radar class with reduced delay times, customisable range requirements, and improved clutter management for improved air-to-air radar effectiveness.
