 Expert: the terrain of the incident is complex, and the possibility of female students directly falling to the ground is low

At present, the search and rescue work is still continuing. It is worth mentioning that the Tianmen Mountain in Zhangjiajie, where the incident happened, has always been a challenging place for wing mounted flight. Only two professional athletes, Sheng Guangqiang and Zhang Shupeng, have completed the flight here in China. The surging news reporter immediately contacted Sheng Guangqiang and asked the professional to interpret and judge the emergency situation.

Wing flight is very dangerous.

The scene is cloudy and foggy with complex terrain

Tianmen Mountain Scenic Area in Zhangjiajie is a very good venue for competitions. There have been many large-scale competitions of wing flight. There are cliffs with an altitude of more than 1000 meters and vertical cliff bodies with an altitude of 200-300 meters, which meet the needs of low-altitude wing parachute jumping. If the vertical distance does not meet this requirement, you cant fly. The unpowered wing flight always glides downward.

Sheng Guangqiang completed two flights in Tianmen Mountain of Zhangjiajie in 2015. In his opinion, the geomorphic environment here has created good competition conditions for wing outfit flight and attracted many competitions and professional athletes. Of course, as a resort for wing outfit flight, it doesnt mean that it is not difficult.

On the contrary, Sheng Guangqiang told reporters, there are many mountains and complex terrain here. In addition, there are many clouds and fogs in the mountains, which will affect the visibility.

In addition, the wind force on the day of flight is also an important factor to be considered, said Sheng Guangqiang: for our wing mounted flight, it is necessary to monitor the weather closely, and the weather without wind is the best. If the wind force is large, the flight speed will become faster, and it may lead to rollover in flight, which is very dangerous.

It sounds that Tianmen Mountain in Zhangjiajie is not easy to fly. If you come here for the first time, you are not familiar with this site, and you are not fully prepared, the difficulty will be greatly increased.

Wing flight belongs to one of the extreme sports.

The wind had little impact on the day of the incident

Back to the current issue of pilot lost contact, public information shows that the 24-year-old female pilot took off from a helicopter with a flight height of about 2500 meters at 11:00 a.m. on May 12. In this regard, Sheng Guangqiang pointed out that this is actually a high-altitude wing parachute.

Wing mounted flight is divided into high altitude wing mounted parachute and low altitude wing mounted parachute. The former generally takes off at an altitude of more than 2000 meters to more than 4000 meters, which is much less difficult than the latter. Low altitude wing mounted parachute is closer to the ground, has shorter landing time and later parachute opening time. The test for the pilot is relatively large and there is a greater possibility of accidents. For example, rope suddenly occurs during parachute opening The wind.

As a matter of fact, there are special training centers in Europe and the United States for skydiving. The trainees will get the corresponding certificates after passing the training. However, the low-altitude wing diving belongs to the category of high difficulty extreme sports, and has not been widely promoted, nor has the public training and related qualification certification. According to the usual practice, the high-altitude pilots usually have to go through hundreds of high-altitude training before they can try low-altitude diving As far as I know, only I and Xu Kai, Zhang Shupeng and Yang Sheng are currently engaged in low-altitude wing flight in China, Sheng said

Sheng Guangqiang is a well-known figure in the field of wing flight in China.

The data shows that the pilots who lost contact with the wing are experienced in flight and have a high take-off distance. Why did they deviate from the route and even lose contact during flight? Sheng Guangqiang said that he had not seen the flight video and could not give the most accurate judgment, but he also stressed that although he took off from a height of more than 2000 meters, it is still unknown whether the actual clearance height is that high.

After all, there are many mountains below. They are not familiar with the terrain, so they may be dangerous. If the wind is strong, there may be vortices among many mountains, which will also cause instability and accidents in flight.

For this reason, the reporter checked the weather on May 12, and the weather broadcast showed that the day was a breeze with little wind impact, but it was cloudy, which may mean that the visibility of the pilot in flight may be disturbed.

But only from the current information, its still hard for you to figure out the real cause of the accident. At present, everyone is more concerned about whether the pilot is still alive? When can it be found?

Wing mounted flight data

Generally, two parachutes are provided, with low possibility of falling directly to the ground

According to local villagers, on the day of the incident, a parachute was opened to fall. On this issue, Sheng Guangqiang gave a professional analysis: for high-altitude wing parachute jumping, in fact, the pilot took two parachutes (only one parachute in low altitude). In addition to the main parachute, there is another parachute. This parachute will open automatically about 300 meters from the ground, which is set in advance u3002u201d

In short, there is almost no direct landing of the lost contact because the parachute cannot be opened normally. Does this mean that the lost contact should be safe when landing? Sheng confirmed, if there were no other impact, the pilot should have been alive.

However, after five days of searching, the pilot has not been found. The current situation is becoming more and more serious. Even if the pilot is still alive when landing, how long can she last without food? The search and rescue team is still racing against time.

It must be mentioned that in addition to the complex terrain, continuous rainfall and low visibility in the mountain, the pilot who lost contact did not take his mobile phone and GPS with him, which also made search and rescue difficult,

If youre in a regular parachute center or base, you can choose not to take it when its safe and secure, but if youre in a strange place or a place where you havent skipped, you should take these contact tools with you, said Sheng

As time goes on, everyone is worried about the lost pilot. As a senior professional wing mounted pilot, Sheng Guangqiang prays: I hope the search and rescue team can find her as soon as possible, and I hope she can be safe.
