Abstract:  In the context of global warming, there has been a significant increase of heat wave events and their impact on air鄄 craft performance is becoming more pronounced. Based on observed data of airport meteorological stations, com鄄 munity earth system model version 2 (CESM2) and Boeing performance software (BPS), the trends of heat waves at Chinese airports during 1973-2022 are investigated. Furthermore, the influence of future heat wave events on max鄄 imum takeoff weight and takeoff distance of B737-800 aircraft are evaluated quantitatively. Results show that dur鄄 ing 1973-2022, the lower the latitude of plain airport is, the more obvious increase of the trend of hot days can be. Heat wave events appear more frequently after 1989, but there is no heat wave events at the high plateau airport during this period. The maximum takeoff weight of aircraft across the four airports would be all limited by the high temperature during the period of 2096-2100. The number of weight-restriction days increases obviously compared to the period of 2010-2014, with high plateau airport being the most severely impacted. When the aircraft are fully loaded at the plain airports, the takeoff distance increases with temperature rise and changes non-linearly, showing a stronger increase with higher temperature. The conclusion can provide an important reference for future renova鄄 tion or construction of airport runway as well as flight planning of airlines
