Local time on May 5 18:30 (Beijing time on May 5 23:30) , a Russian boat plane that flies to Maermansike from Moscow (because SSJ-100) breaks out breakdown to fold return, in Xieliemeijiewo the on fire when airport crash-land, two children include to share 41 people to die inside in on machine 78 people.
According to message of Russia satellite news service, at present the black box of the plane already was found, accident reason still is in in deciding. Russia TV station released plane pilot Dennis Xiefuduojimofu (Denis Evdokimov) allegation. He expresses, after the plane is hit by lightning in sky, radio news report has had short time to interrupt, below the in ground dispatcher help after restoring, set course lets plane crash, landing gear of the plane when descending ruptures, engine on fire. Xiefuduojimofu still confirms, the plane is the on fire after descending, is not before of the report in flying. Must be fully loaded with fuel crash at that time, this may be the cause that causes a plane to produce bounce and on fire in land.

Although final findings report has not come out, but we as before can from this the first paragraph a few short sentences win the bid red part analysis gives a lot of businesses, today, boat knows to crash from the Russian ship that this says for a few respects incident:
Why to put oil with respect to crash?
"Must be fully loaded with fuel crash at that time, this may be the cause that causes a plane to produce bounce and on fire in land. This may be the cause that causes a plane to produce bounce and on fire in land..
Yesterday, after news event is given out,
We notice comment area has so a word:
Combinative pilot says " full oily crash is accident reason likely very " , why doesn't Russian boat put oil first again crash? Is oily language put in be still being written down is the popular science last month for nothing?
" the oil that 10 thousand meters of headroom put, where to go to? "
Two case that must descend cited inside the article: Oil is put in Dong Hang sky 39 tons, plain boat circles several hours in sky, after consuming fuel, descend again. The purpose is to reduce the touchdown of the plane weight. So why doesn't incident of this crash of second Russia boat put oil? Because SSJ-100 did not provide the opening that put oil,the reason is.
Go up century 50 time end at the beginning of 60 time, FAA regulation, if the greatest takeoff weight of the plane is the as greatest as its,land the rate between weight is more than 105 ％ , criterion this plane can provide the system that put oil. Do not deserve to have conversely. 60 time mix the century on during 70 time, change considering what cost reachs engine, FAA cancelled 105 ％ principle: Fly 15 minutes in, if can satisfy FAR 25.119 (land climb) with FAR 25.121 (into close climb) climb requirement, won't provide the system that put oil. Clearly, SSJ-100 does not provide the opening that put oil.

So some of reader wanted to ask: Since sky is medium the system that put oil is not OK, why not boat of plain of follow the lead of uses up some of fuel to descend again more in sky, circled two rounds only however?
Our couple leaves this question on one hand for:
Can be struck by lightning make really plane out of control?
"After the plane is hit by lightning in sky, radio news report has had short time to interrupt, below the in ground dispatcher help after restoring, set course allows aircraft force "
Above all, stabilize soldier's morale, do not fear: The thunder of modern plane defends the system is done very well, be being hit to make the plane causes casualty by thunder last time still was 1967. Be being hit to make the plane causes casualty by thunder last time still was 1967..
Now civil aviaton plane not so be afraid of be struck by lightning, when weather is actually bad, we fly to basically have with thunder every time " intimate contact " . Did not feel? That was opposite! The thunder and lightning that has rigor because of modern plane defends technology, basically form by 3 parts:
1. complete machine guides a design. Design crust into Faraday namely basket, this is to thunder have screen effect -- whole thunder electric current is met the exterior glide from the plane, and the airframe of won't penetrable plane, cause loss to internal system;
2. fuel system produces report to emerge to prevent thunder to hit scintilla adds the fire prevention of outfit to spend a design.
3. has the special design that prevent thunder on all boat cable systems, prevent thunder to cause interior to produce report to emerge local high tension.
Military plan puts brush, civil aviaton plane to it similar, deploy 4~6 in plane wing tailing edge commonly (the graph is " aviation knowledge " of Wang Yanan chief editor unlawfully posses young other people oh)
According to Russian intermediary report, organic team member calls a plane be struck by lightning of the experience after Ceng Zaiqi flies, this may be the reason that the wiring on the plane malfunctions. Be struck by lightning still brings about malfunction of plane automation system, during land plane for two times dash against runway.
The thunder that appears in nicety with the above-listed defends technology, if say the important fittings that is hit to cause by thunder is not quite good,use, possibility has, but very low very low, the reason with real wreck even via attestation of the ability after final investigation. But the word says again, no matter because,be thunder, if the system is out of order, boat report is very bad. Because be in attitude information (be like height, speed, pitch angle... ) below offerred abnormal case, the plane circles in an airspace is very dangerous, must choose to descend as soon as possible, this also may be why air man did not choose to continue the reason that circles in sky.
What is on fire reason after all?
"The plane produces bounce for many times when trying to land, this damaged likely airframe gasoline tank, cause on fire of machine back ministry. Pilot says, unit staff is operating the plane drops any troubles were not encountered in the process, "Rate is not high, very normal. We are basises of flight manual act. " however, right now weight exceeded this plane to descend far requirement, because its gasoline tank is full almost, the greatest takeoff weight of SSJ-100-95B plane is 45.88 tons, because these 45 tons of right-and-left weight want security,descending on track is extremely difficult. Xiefuduojimofu says, he and his deputy drove to descend according to the program an overweight plane, the likelihood is to land the jolt in the process causes plane on fire. The likelihood is to land the jolt in the process causes plane on fire..
At present the on fire reason of this plane had be notted confirm. According to Russian federal investigation committee Moscow investigates the preliminary judgement of total bureau, fire cause is wiring malfunctions bring about electrical wiring short circuit.
Airport monitoring
In addition, distress landing of the ability after two bounce that driven pursues medium is successful, although the plane descends weight is ambitious descend at safety weight, from video we also can see, condition of plane ground connection is extremely unfavorable. From inside the graph we can guess reason of its on fire:
1
The success just descends after bouncing twice,
Plane fragment hits leakage gasoline tank.
2
After landing gear ruptures
Hit the gasoline tank of abdomen of two side wing, machine,
Make its are poured out of.

Combine above at 2 o'clock, the main reason of plane on fire begins from fuel. But aviation kerosene is very difficult commonly be ignited by bright fire. A kind of situation is very only special, it is fuel splash when local pulverization, the vapour of pulverization can be ignited quickly by bright fire. When bump, these two conditions all are accorded with, bump make fuel system burst, the fuel that splash comes out is local vaporization is very fast. Bump have high temperature and bright fire, the meeting is flashy be ignited, fuel is in plane rear centrally, of the fuel on fire that sheds backward namely, we can see absolutely of Russian boat accident in video.
Take the person of baggage, you are really selfish.
A spokesman says Russia board of inquiry, incident already caused 41 people death, include 2 children. Move those who pursue OK and clear to see the passenger that is carrying boot. A lot of passengers take baggage to grab, bring about a plane to withdraw by incur loss through delay.
An airport official shows: "A lot of passenger block up urgent withdraw, because although have,be indicated, they still are grabbed from rack of the top of head take baggage. " in addition, russia international article sends telecommunications company also the word of faceless message personage weighs cite, because partial passenger insists to want to take portable baggage first, bring about a plane to withdraw to be delayed.
Can say this 41 numbers of this accident, cannot take off implication with these people, boat knows to appeal everybody here, help a person one life, get the better of make a surname of 7 class float. Although do not give scattered help,go up, also did not block a means of livilihood of others please.
Plane crash and on fire, how should be you done? Benridi requesting an audience is pushed 2 times send. Urgent when withdrawing, taking baggage to flee for one's life as good as commits murder at " " , benridi requesting an audience is pushed 3 times send.

Small make up mix midday " circle " when the friend outside has a meal, have this second event a little, the friend says fancily, whether can do later " one key lock is dead " rack function, when withdrawing once need is urgent urgently, everybody also is fastened " remember with concern " wear that " family property " . You say, how?
