The tibletan plateau has an average elevation of 4,500 m or about 14,800 feet. It is considered to be the highest plateau in the world hence the nickname the roof of the world. It has a total area of over 2,500,000 km². The Mount Everest can be found on the southern part of this vast plateau.
Barely any plane flies over this plateau. The area is literally five times larger than France.
Over the period of the Second World War over 594 planes got lost in the mountains never to be seen again making the loss rate of planes flying over the region as high as 50%. (A clearly unacceptable loss rate for any of aviation company).
One of the main reasons why international airlines do not fly over the plateau is that despite being able to fly over the region at altitudes over 30,000 feet, airlines protocol states that during cabin depressurisation and engine failure,the plane must descend at 10,000 feet which is not possible since the average elevation is 14,000 feet.
If you would like to try a local flights in the region the two local airports in the region are Lhasa gonggar and Xining Caojiabao.
The flights are as follow:
Lhasa Gonggar to Kathmandu
Xinning Caojiabao to Taipei, Tokyo and Kuala Lampur.
