The plane does not have satellitic phone, AOC passes ACARS connection, AOC lasts through supervisory system monitoring.
Set is initial feedback, the plane encounters extreme weather when Macao be born, preliminary judgement is wind shear, 0-100 of wind direction change, a landing gear when be born is damaged, may inspiratory engine, plane answer flies, invalidation of communication navigation system, single shot invalidation.
Aircrew is used reserve navigation system, aircrew announces Mayday, fall fully Shenzhen, shenzhen first time opens an examination wheel case, at 11: Shenzhen of 58 safe be born.
The plane starts lash-up to withdraw on track, release slide, total security withdraws aircrew, passenger end, the passenger already arrived await machine building. At present incident is being investigated, detailed circumstance awaits a cable.

On August 26, capital aviation JD5158,
By empty guest A320 hold fly, register date B-6958,
Executive Kunming - Hangzhou airliner,
At 14: 54 from Kunming long water airport takes off.
According to the passenger's description,
After taking off probably after 20 minutes,
Hear the sound with the very flurried pilot in broadcast suddenly to cry,
"Engine room is applied press aerobic face guard to play piece " ,
Empty elder sister reminds everybody to take veil...
The passenger feels 45 degrees of horn drop plane head over heels downward at that time,
Have strong weightlessness feeling.
What is wind shear --
Wind shear is a kind of meteor, wind vector (wind direction, wind speed) in sky the level is mixed (or) the change on vertical distance.
The shear that wind shear can divide the horizontal shear that is horizontal wind, perpendicular shear of horizontal wind, perpendicular wind by wind direction. The existence of perpendicular wind shear will be right flight of building of bridge, high level, aviation cause destroy.
The wind shear that happens in low altitude is a plane take off and land a of level important and critical factor, be called by people " aeriform killer " . Accordingly, how to answer the obligatory course that shear of low altitude wind is every air man.
Caused the United States as a result of serious wind shear 1985 Dalasi - Foss airport prang 137 people die. From now on, wind shear is regarded as an international task begins to consider. Coping with wind shear to get best idea at present is escape it. Because certain blast shear is the function place of existing plane,cannot defy. The air man that has wind shear grooms and flight operating sequence is installed, in the airport installation wind shear is explored and call the police system, and airborne wind shear is explored, give an alarm, evasive system, it is the main avenue that be reduced at present and avoids wind shear harm. After 1985, all American planes installed wind shear detector. Canada is acting 1990 begin to install.
Aviation safety does not have bagatelle, hope recent flight accident can raise the vigilance of each airline, wish everybody goes out travel is restful!
