Airbus has delivered Tibet Airlines' first A319 to be assembled in China.
The aircraft, which rolled out of the Airbus Tianjin assembly line last week, can carry 128 passengers in a two-class configuration. It is powered by CFM International CFM56-5B engines.
It will operate out of Lhasa Gonggar airport, one of the highest in the world at 12,000ft (3,660m), and be deployed on services to Shenzhen via Chengdu, says Airbus.
It is certified for high altitude operations and is capable of Required Navigation Performance - Authorisation Required (RNP-AR) procedures, which allows it to fly along a predefined route using on-board navigation systems and the GPS-based Global Navigation Satellite System.
Tibet Airlines selected Airbus subsidiary Quovadis for its RNP-AR operations.
Airbus has delivered 105 A320-family aircraft to 11 operators since the Tianjin facility, its first final assembly line outside Europe, began operations in 2008.
Beijing-based flag carrier Air China has a 31% stake in Tibet Airlines, while government-linked investment companies from the province own the rest of the carrier.
