The environmental factors in survivable civil aircraft crash accidents have a significant impact on passenger evacuation. Based on the characteristics of typical survivable civil aircraft crash accident scenarios, this paper proposes an experimental method for passenger emergency evacuation that can simulate typical crash accident environments, and introduces simulation methods for aircraft body attitudes, environmental sound/light, cabin obstacles, visual environment of portholes, and high-precision measurement methods for the personnel evacuation trajectory. The impact of crash environment factors such as aircraft body tilt attitudes, accident sound/light environments, and aisle obstacles on the emergency evacuation of civil aircraft passengers is studied through volunteer experiments. The results indicate that the proposed experimental method for emergency evacuation considering the impact of crash environment and the simulation scheme for crash environment are feasible, and obtain effective experimental data; the aircraft body attitude change within a pitch angle of ± 5° has no significant impact on the total evacuation time and evacuation efficiency of multi-passenger evacuation, and the difference in the speed of passengers moving uphill and downhill in the aisle area increases with the increase of pitch angle; the sound and lighting environment of the crash accident have a certain impact on the emergency evacuation of passengers, and the accident background sound can reduce the total evacuation time, while emergency lighting increases the total evacuation time; obstacles in the cabin aisle overall increase the total evacuation time, with a shorter distance between the obstacles and the exit resulting in lower evacuation efficiency; compared to movable obstacles, fixed obstacles can lead to lower evacuation efficiency.
