The 12 professional subjects cover a wide range of areas, including flight performance, structure, design and configuration, Electrical system, propulsion unit, flight control system, ground control station, communication and data link, Airborne human computer interaction, general respect, continued airworthiness and system safety. The compliance tests involving assessing main material performance, structural strength, flame resistance, Crash weakness, gas toxicity, environmental conditions of equipment and systems, software simulation, Datalinks, ground control station, overall system functionality, electromagnetic compatibility, flight performance and flight stability characteristics, etcetera. Throughout the validation process, we meticulously scrutinized every component, equipment and the entire aircraft for any potential defects, faults or interference. This scrutiny extended to both laboratory tests and flight tests. Over 1500 compliance TestFlight, along with more than 40,000 safe flight record, EHANG-two 16 has finally met all the requirement To complete the compliance review, the TC process has been conducted with scientific rigor and authoritative oversight.
