INVESTIGATION ON THE LIGHT ENVIRONMENT OF CHINA'S ACTIVE WIDE-BODY AIRCRAFT (PP13, 309-318)

Currently, the typical models of China's existing wide-body aircraft include the Boeing b777- 300ER, A330-300, and Boeing787-9, with varied degrees of differences in the light environment in each model. In this paper, investigations on the influencing factors of cabin internal comfortability have been carried out based on the abovementioned three types of cabin lighting configurations for wide-body airliners. The task performed during the investigation is to measure indicators, such as cabin illuminance, luminance, colour temperature, colour rendering properties, etc. Through comparisons and analysis on three models of aircraft based on obtained statistics, the thesis illustrates and affirms merits of Boeing787-9 in terms of lighting environment conditions. Meanwhile, defects of lighting environment of China's existing wide-body aircraft still exists. The thesis will make out series suggestions on measures to upgrade lighting environment conditions of existing wide-body airliners to achieve its goals of providing a more comfortable light environment for passengers.
