Abstract:In normal weather conditions, civil aircraft pilots perform visual operations(such as observation and interpretation of instruments, monitors, etc. ) in the cockpit in a relatively comfortable light environment, but in harsh weather conditions, the sudden appearance of strong glare sources in the cockpit will cause damage to the pilot’s visual, physiology and spatial orientation, limit the pilot’s response time, and directly threaten the flight safety. In the design of cloud and lightning simulation system in light environment simulation, aiming at the different simulation indicators of cloud and lightning, the cloud simulation and lightning simulation system are used to simulate cloud and lightning on the ground respectively, realizing the simulation of severe weather environment on the ground, such as thunderstorms, crossing the clouds etc. ,which can provide multi-function and reproducible optical verification conditions for the optical integration design, visual ergonomic design, verification test, human engineering research of the cockpit.
