This Asian Region is Recognized as a Hazardous Area for Aircraft, Leading to Avoidance by Pilots

None of that. Indeed, to explain why planes do not fly over Tibet, there are three reasons, as the site specified Simple flying.

1. The Tibetan tray is very high at altitude

On average the Tibetan plateau amounts to almost 5000 meters. It is less than the more than 8000 meters of Everest and even less than the cruising altitude of an aircraft which is around 9000 and 12,000 meters above sea level.

However, in very rare cases, planes can undergo accidents related to cabin depressurization. It is when the air pressure is located on the plane falls suddenly and the oxygen levels become very low. Before takeoff, the guests and hostesses of the air show you how to remedy it thanks to the oxygen masks.

In such cases, the pilots can start a descent from the plane at a level where the air located outside the cabin is easily breathable. Usually, the average altitude where possible is nearly 3000 meters (around 10,000 feet). In fact, the relatively high altitude of the Tibetan plateau would prevent planes from being able to descend safely to counter the depressurization accident.

2. The aircraft fuel can freeze

This is obviously not inherent in Tibet. The more we rise in the heavens, the more the temperature drops. However, the very cold temperatures in the region increase the risk that the fuel starts to freeze in full flight.

Indeed, according to totalnergies, the fuel mainly used to feed the aircraft is kerosene called Jet A-1. The latter has a freezing point evaluated at -47 ° C. In the flight and cruising altitude, an airplane flies between 9000 and 12,000 meters above sea level. At this height, the air temperature is on average -56.5 ° C.

Of course, tanks are protected from external temperatures so that fuel cannot freeze. But zero risk does not exist and by plane an accident is very often fatal.

Because if the kerosene came to freeze, small balls would form, then obstructing the engine which could not be supplied with fuel, therefore causing the stop of the engine (s), in full flight 12 kilometers above sea level. We don't give you a drawing to explain that it is dangerous.

3. To avoid turbulence

This last reason is mainly the comfort of passengers. And it is true that a flight without turbulence is more pleasant than a trip where the cabin is constantly shaking. And by flying over mountains, where the air currents can be violent, turbulence can be just as much.

So inevitably, if planes risk flying over the highest mountain range in the world, turbulence would only be more important. In fact, for all these reasons, very few airlines risk flying over Tibet. You can realize it yourself by going to Flightradar And thus observe that the region is an area deserted by planes.
