A preliminary study on passengers' thermal responses when boarding a flight in winter

An experimental research was conducted to study passengers' responses to the thermal environment when boarded aircraft cabins. The results show that passengers adapted to the thermal environment by behavioral and psychological paths. Before entering into the cabin, the Sick symptom, thermal sensation and thermal discomfort was obviously higher at walking state than waiting state. Subjects' thermal comfort were achieved by using personal air outlet (PAO) and adjusting clothes. And after enter the aircraft 10 min -15 min, the difference of subjective responses between different pre-states became small, because of actively adaption.
