Wilderness Challenge for Live Broadcast

Yes, at the southeast point of Mount Everest...about 7,500 meters!

Since they took off the plane this time to rescue Dr. Zhang, Yan Bin contacted the tent base of the rescue team early in the morning.

Nima, so tall!

The audience could not have imagined that Master Xu had to fly to such a high position for his first emergency rescue.

And judging from Yan Bin's hesitation in speaking, such a high level requires extremely high requirements for his pilot's control.

After all, flying over Mount Everest and hovering on Mount Everest to save lives is not a concept!

Anyone who has a little knowledge of aviation knows that the most difficult part of flying a helicopter is not how far and how high it flies, but the hovering and control!

Especially for hovering, a slight gust of wind will have an impact on the stability of the fuselage, and high mountains are most prone to gusts of wind.

7500 meters... If it's really this height, then it's fine!

When Chen Xu heard the coordinates, he immediately breathed a sigh of relief.

In this regard, the audience expressed their incomprehension. Why did Master Xu still say yes to such a high emergency position?

Could it be that Master Xu is shaking M?

The task is not difficult and uncomfortable?

Looking at the many suspicious barrages on the screen, he explained with a smile: This height is indeed a big resistance for our emergency rescue, but it may not be a bad thing for the victims.

People who have played mountaineering or skydiving should know that when the altitude exceeds 7,000 meters, it is called a death zone, because the oxygen content there is only about a quarter of that at sea level, even for professionally trained people. You also have to wear oxygen cylinders to survive.

Therefore, Dr. Zhang and his team members should have worn oxygen cylinders when the avalanche occurred. You must know that there are two main fatal factors for snowstorm outbreaks. One is low temperature frostbite, and the other is hypoxia asphyxiation.

Since they have oxygen cylinders for support, there should be no serious danger to their lives in a short period of time. However, it is almost impossible for human beings to survive for more than 48 hours in an extremely cold and oxygen-deficient area like the death zone. Therefore, Yan Bin , we have to speed up the time!

Okay! Team Chen!

Yan Bin answered very simply.

If,

It was called Team Chen before because of Li Qing's order, but now the phrase Team Chen is a true acknowledgment of Chen Xu's command status.

After all, several people don't know Chen Xu well, and at such a young age, it's normal to feel a little dissatisfied in their hearts.

But after this journey, I listened to his analysis.

Yan Bin and the three began to have a different impression of Chen Xu.

Although the fragmented knowledge of high altitude, oxygen content, oxygen cylinders, and snow disaster conditions is not difficult to remember, it is not easy to integrate and link them together to form crisis management conditions.

This not only requires a solid memory of outdoor knowledge of snow mountains, but also requires carefulness and the concept of survival in crisis.

The audience in the live broadcast room also understood a lot after listening to Chen Xu's explanation.

Some people also recalled that Master Xu was inhaling oxygen when he performed a live skydive on the Matterhorn in the Alps, and the altitude of the plane at that time was about 7,000 meters!

Time passed minute by minute.

The helicopter rose higher and higher.

And the four of them also started to take out four small bottles of oxygen tanks from the first aid equipment in the back in front of the audience, fastened them around their waists with the fixing belt of the safety suit, and then put the transparent breathing tube, inserted into the nostril.

The scene outside has long since turned into a snow-covered world.

The glacier of Mount Everest, like a proud sword, goes straight into the sky.

Occasionally, the audience can see that the mountain is already a vast green. Even such a huge mountain range still looks a little small in the picture.

Just because the current altitude is 7200 meters!

While Chen Xu was explaining to the audience, he still didn't forget to turn his head and look at the surrounding environment.

When he saw the clouds around the peak, he frowned slightly for a moment.

After thinking about it for five or six seconds, he turned his head and said to Yan Bin: Yan Bin, from now on, add 10% to the fuel you calculated and reserved!

this……

When Yan Bin heard this sentence, he suddenly became a little dazed.

As a professional pilot, especially when flying in high-altitude areas, you must always calculate the altitude, the weight of the vehicle, the weight of the personnel, and the degree of fuel consumption.

Only in this way can he estimate how many disaster-stricken people can be accommodated at that time, and successfully return to the voyage safely.

Yan Bin had already figured these things out.

But who would have imagined that now Chen Xu suddenly interrupted his plan, you know, 10% of the fuel volume is not a decimal, it can almost carry one more person affected by the disaster!

So, Chen Xu pointed to the clouds on the top of Mount Everest outside the window and said, Did you see those thin clouds floating to one side along the top of the mountain?

Cowin?

After Yan Bin glanced at it, he immediately let out a cry of surprise.

That's right, banner clouds are one of the symbols for judging the wind force in the upper part of the Mount Everest glacier. They are formed by convective cumulus clouds. You can judge the wind force in the upper part of the glacier according to their floating position and height.

Chen Xu explained: I know you should calculate the wind force of Cowin. The upward wind is small, and the downward wind is strong. Now it is basically on the same level as Mount Everest, which means that the wind force is about level 9.

That's right, I counted as level 9.

Yan Bin nodded while secretly admiring Chen Xu.

As a pilot, he was already sensitive to high-altitude weather, but he did not expect Chen Xu to be able to spot Cowin so quickly, and his calculations were so accurate.

But you ignored the direction!

Chen Xu shook his head slightly, Usually there is a strong westerly wind blowing on the upper part of Mount Everest, so the direction of the banner cloud should be in the east, but the banner cloud in front of us has begun to shift to the northeast, which means that there is a strong unstable airflow. Intervene in it!

If my guess is correct, within an hour, there may be heavy snowfall or extreme weather, so you have to plan early and reserve fuel to fight against extreme weather!

After Yan Bin heard this, his eyes blinked twice, obviously shocked.

And the two first aid soldiers behind him, Liu Yan and Sun Yue, couldn't help but think of what Team Leader Zheng Yuan said to them before he left: You should listen to Chen Xu in everything, this kid is extremely sensitive to changes in the weather outside. With insight, he was the first to discover the waterspout in Shenzhen City Bay last time.

Now it seems that Nima is right!

I didn't expect that China really has such a great outdoor survival and emergency expert!

Afterwards, Yan Bin kept comparing Cowin's dynamics, comparing it with the high-altitude weather changes recorded in the book, and calculated for four or five seconds before he realized, and hurriedly exclaimed: Team Chen! Thank you! I got it!
