(prcenter.de) The climatic change and the associated partial extreme weather conditions lead to more flight accidents. Christian Scherbel reports of the residents of Munich flight safety consultation Aerosecure. Thus the portion of the accidents caused by weather conditions trebled itself in the last two decades more than. Were weather-conditioned four per cent of the main causes of accident in the period between 1986 and 1995 only about, then this number in the decade had risen 1996 to 2005 to 13,0 per cent.
The largest threat lies according to aero ECU RH statistics with small view and Scherwinden during takeoff and landing as well as on freezing up of the bearing areas. Afterwards follow turbulences, thunderbolt and thunderstorms. In view of at present quite frequent summer thunderstorms Aerosecure of the question followed, which effects a thunderstorm can have on the flight. “During the flight an airplane behaves similarly as a car as Faraday's cage so mentioned”, explains Scherbel. “The metallic outer hull of the airplane prevents that lightning penetrates into the inside, although with a thunderbolt amperages by up to 200,000 ampere and tensions are reached by several Megavolt.” The Canadian transportation authority TC in Ottawa sees therefore in the most spectacular phenomenon of a thunderstorm - lightning - only a small danger for the air traffic. “As many more dangerous TC classifies the danger that the pilot by lightning briefly or electrical devices could go blind be damaged”, so to Scherbel further. Accidents by lightning strikes are however very rare.
For Timothy Miner of the Flight Safety of magazines rank among the largest weather dangers freezing up, strong hoist, gusts of wind, Scherwinde, turbulences, small Tornadoes and poor visibility. According to Miner thunderstorms at the goal airport can become likewise dangerous however, even if the landing only some minutes takes place after the tempest. An example of it is according to Scherbel the accident of a American airline machine on 1 June 1999, which landed after a heavy thunderstorm in Little skirt and among other things because of aquaplaning at the flooded Runway beyond the delimitations. 11 humans died thereby. Jack May of national the Weather service in Kansas town center classifies thunderstorms as a danger, which is dangerous for all pilots and all types of aircraft. Thunderstorms on en-route flights are critical not only for private pilots, but also for large passenger planes, which traditionally to larger heights fly. Machines like Boeing 747 fly to approximately 30,000 foot height (about 10,000 meters). According to Kelsey Curtiss of that Texas A&M University can amount to the height of thunderstorm over country however more than 55,000 foot and over the sea even 75,000 foot. Flying over is no longer possible in such cases, so the expert additional dangerously becomes the thing by the fact that particularly high Gewitterfronten store more energy and concomitantly more strongly and more violently fails.
Protection device in airplanes before thunderstorms
* Aluminum outer skin: Aluminum as a very good leader prevents the penetration of the energy of lightning into the cell and makes a drain possible into the atmosphere. With airplanes from GRP components materials at the outer skin particularly well leading fibers are inserted.
* Screen, grounding and overvoltage protection to the protection of cables, electric circuits and instruments. These preventive measures are decreased from the aviation authorities.
* Lightning conductor
* Doppler radar for the early discovery of Gewitterfronten: Measurement of direction and speed of moving objects.
* Use of extensive meteorological data and internal signalling system with particularly heavy thunderstorms, “Supercells so mentioned”.
* Meanwhile for example researchers of the Friedrich Schiller university Jena work on as one can prevent a developing of lightnings. They want to suck threatening thunderstorms off proper from the sky. With three trillion Watt a strong laser beam change it the characteristics of air. It becomes electrically conductive like a wire. If a thunderstorm approaches, the researchers want to make a connection to the cloud, by which lightnings are to unload themselves with the laser beam. A aufwändiges procedure, which appears at the moment not yet practicable.
Who wants to know, which types of aircraft are affected by weather dangers particularly, this can let investigate with Aerosecure (www.aerosecure.de). The residents of Munich operate a data base with safety profiles for over 300 international airlines. In it contained are among other things business philosophy, fleet and fleet evaluation (like age, maintenance, type analysis) as well as a accident statistics with cause analysis. Between four and eight sides comprehensive dossiers can be downloaded under www.aerosecure.de and cost between 6,80 and 9,80 euro.
