Why Do Planes Avoid Flying Over Tibet?

If you look at the flight paths of planer journey around the human race , you may note a few oddities . One is that they do n’t appear to trip in straight paths to their address ( the answer to this one isfairly obvious ) and , if you really go into detail , that very few planes seem to fly over Tibet .

If you recognize anything about the Tibetan terrain , it ’s that it contains a raft of mountains and elevated tableland . While this might not seem like a job for planes – which can simply fly mellow than the pile – they are the rationality why aircraft lean to avoid fly over the region .

One job with fly over Tibet is that the mountain run lead in a lot of turbulence .

" In its most bare mother wit , turbulence is a commotion in the air , and is not unlike the movement of wave and ocean currents . If there are no obstacles in the way of an incoming wave it will ' menstruate ' nicely , but if it hits a ocean bulwark , say , it will break up and you’re able to see the break to the undulation , " Darren Ansell , Space and Aerospace Engineering Lead , University of Central Lancashire , explained in a small-arm forThe Conversation .

" As air hang over man - made structures and natural terrain such as mountains , the air flowing is disrupted and causes the air above and around it to become troubled . So if you take off or body politic from an airport closely to a heap range of a function or very hilly terrain you are more likely to experience this kind of upheaval during and shortly after take - off . "

While it is potential to pilot over Tibet , the mountain ranges can lead to a rocky ride . Another problem is safety . Planes take flight far higher than the average5,000 - meter(16,400 - pes ) elevation in the area . But should the cabin depressurize ( a rare event ) , pilots may necessitate to descend to around ( 3,000 meters)10,000 feetwhere the airwave is breathable , before look toland in a nearby airfield . This is a second of a job when descending to that height would simply doss you into a mountain scope .

For these reasons , as well as a lack of areas where an pinch landing place could be carried out , planes that are not landing in the area ’s airports tend to avert vaporize over Tibet .
