One of the issues that traditionally tends to arouse a greater fear during the flight is the emergence of turbulence on the way and that these might be, in most of the cases, without prior notice. Therefore, in these lines we will focus on knowing the phenomenon of turbulence and its causes, with the aim that this us serve as a soothing element for the future. To who not has happened on a route that does not have to be a long distance, as, for example, cheap flights to London, you have experienced turbulence? Turbulence consist of the air movement, which usually manifests itself in an unexpected manner and that many times, when the sky is clear, is imperceptible to the human eye. These unexpected movements of air may occur as a result of various factors, related to the weather conditions: atmospheric pressure, Jet engines passing a short distance from the present situation of the aircraft, the existence of masses and fronts of hot or cold air, as well as the emergence of storms or the existence of mountainous foothills. Generally, it is more common to find turbulence when the plane is flying at high altitude, so it is less likely to suffer this type of contingency in flights to Ibiza that on flights to Paris, for example.
There are several problems arising from the turbulence in mid-flight. The most important of them is that this atmospheric phenomenon has become the leading cause of injuries among passengers and crew members, especially when the turbulence occur while passengers moving around the cabin of the appliance. In addition, some of the handicaps of this air movement are that, normally, turbulence are most noticeable in the cabin than in the cockpit where pilots, are sometimes impossible to predict and occur when there are no clouds. Some statistics related to the turbulence: between 1981 and 1997, the big airlines suffered 342 cases of turbulence, which killed 3 passengers (two of them traveled without belt) and injured Bass a total of 80 people, of which 73 were not wearing seat belt fastened.
