Processing planes at Domodedovo (22 photos)

Winter this year began sternly - first frost, and now fills up with snow.




Snow technique works around the clock. Creepy units with huge buckets and brushes sweep the snow off taxiways on the airfield and runways pour reagents.



If technical terms, the deaysing (or, in our opinion, icing aircraft) - a procedure for cleaning the airfoils from adhering snow and frost formed and coating them with a protective structure. If it simply - "watered plane dirtiest».



That is, if the process does not hold or carry out properly - you can see here in this wonderful documentaries. You can still remember the crash of the Yak-40, which killed Artyom Borovik. Try to explain popular. The wings and tail of the aircraft - particularly constructed surface, the shape of which is designed perfectly to provide flight (due to the pressure difference above and below the surface). If formed frost or snow sticks - form changes, aerodynamics and aircraft deteriorating "can not hold on to the air" - a tendency to stall. Simply put, the plane begins to fall. What other problems can happen - getting ice from the wings of the engine, or, for example, plastered with snow sensors that read speed, which result in incorrect / inconsistent information to pilots. All this is particularly critical during takeoff and climb, so the bulk of the related flight incidents connected with this phase of flight.



The procedure is performed, of course, not at the very ladder - there are few places the sea airfield equipment and people go. So first embarkation of passengers on board, and then begins taxiing to an open parking lot, where he will be held deaysing.



The protective coating has about 15 minutes, so the place chosen so that after treatment it was not necessary to steer away vzlёtki (e.g., if the terminal at the other end of the airfield).



As far as I understood from his observations, foreigners prefer to pour the entire plane as a whole, including the fuselage, and our mainly limited aerodynamic surfaces.



Deaysing - one of the most spectacular aviation procedures, especially when it comes to giant ship like this Boeing 777 Singapore Airlines.



Many (like me) will probably be surprised to learn that the liquids are actually two: the first under high pressure wash the snow and ice, and then a second protective coating is applied.



If the cleaning liquid is delicate pinkish hue, the protective - a clear turquoise color, which turns into a kind of white aircraft "cucumbers» S7.



Speaking of them. The second plane, an example of which we will look processing - Airbus A319 Siberian. Planting is completed, the ladder complex and begins taxiing to the open area.



Machine comes with a liquid, the operator sits in the cradle and turns the hose on a telescopic "leg».



Cleaning fluid.



Protective.



Then the car goes round the plane and starts processing on the other hand.





Processing is complete - you can fly!





The next "client" - 737 Transaero.



Another eye-opener for me was the fact that there are different categories of fluid and there are various proprietary formulations. Depending on weather conditions using different concentrations of compounds. In general deaysing spend even in the summer - if you pour cold full tanks of fuel, already can form frost. They also found that no harmful chemicals are not there - if a person accidentally gets, it's okay. Although it was to be poured with hot soapy water, pleasant too little.



To prevent damage to the road plane and send it instead flight to repair, moving parts of the machine equipped with special "mustache" - special sensors that stop traffic at the touch (who knows how the overall car in the subway - will understand what I mean). A little further on the photo you deliver diesel fuel.



The machine is called the «Elephant» - an elephant. If I understand correctly, one such is worth about $ 1 million. There are certainly more economical option - a technician sits in the cradle, takes the hose and watering the plane itself. But Domodedovo is not practiced.



All a pleasant flight!
