Passengers' comfort experience during flights is important in choosing their flights. The focus of this study is passengers’ perceived comfort in different climbing angles during ascent. Twenty-six participants were invited to experience three inclination angles including 3°, 14° and 18° in a Boeing 737 cabin. The angle of 3° was used to simulate cruising stage and the other two were used to simulate different climbing angles. Participants experienced each setting for 20 min where the perceived comfort, their heart rate variability(HRV), and their body contact pressure values on the backrest and seat pan were recorded with questionnaires, HRV bands and pressure mats respectively. The results indicate a preference of 14° inclination angle resembling the cruising angle (3°) and having the slowest moving speed of the center of pressure (COP) on both the backrest and seat pan.

To study passenger contentment data and design for a better hygiene experience for a future aircraft: flying-v, researches and design were performed step by step. Firstly, to understand the overall situation of current flying experience, data were gathered from three co-creation sessions and a survey of 128 participants with experience of long-haul flights. Negative observations related mainly to physical discomfort and feelings of boredom. While social interaction was important for some passengers, it was generally superseded by the need for privacy. Relaxation was seen as important as well by the passengers. In-flight entertainment was frequently dissatisfactory, and eating was something passengers looked forward to and viewed as a type of entertainment. Some suggestions are made as to how these findings could be integrated into future aircraft design. Hygiene, a small part of the trip can also influence the experience of the entire trip. Co-creation sessions and online surveys were conducted again with a focus of hygiene/refreshing experience. The main complaints for current situation were: long queue, small space, low and small basin, nowhere to put personal belongings, unfriendly door, lighting condition and etc. Base on people's preference studied in the research, different conditions on seat, light, basin, storage,facility were build with VR technology for a experiments. 28 participants were involved and their contribution inspired the final design of a new hygiene space which is separated from toilet was created. Evaluation on this design involved 33 people was also done in VR environment. The data shows significant improvement on comfort and satisfactory.
