Qamdo Bamda Airport
Changdu Bangda Airport (IATA: BPX, ICAO: ZUBD), also known as Qamdo Bamda Airport, is an airport serving Qamdo (Changdu), Tibet Autonomous Region, China.It is located in the village of Bamda (Bangda).It was surpassed by Daocheng Yading Airport, with an elevation of 4,411 m (14,472 ft), on 16 September 2013.[2] It has a very long runway, 4.5 km (2.8 mi), a necessary feature to accommodate the reduced engine and lift performance that affect aircraft at high altitude, requiring higher than normal takeoff speeds and therefore longer takeoff and landing runs.[1][3] Runway repairs took place in 2007 and 2013 after decay from the weather.
