Chapter 678: The 50-kilometer airport is open to you
The Qinghai-Tibet Plateau has complex terrain and complex weather conditions. Many years ago, it was considered a restricted flight zone. This was partly due to the limited performance of the aircraft at that time, and partly due to the complex and changeable weather conditions in this airspace.
Civil aviation aircraft flying on plateau routes are equipped with two captains, which is rare in other domestic routes. The plateau combat capability has always been one of the key combat capabilities of our military. Take the Air Force as an example, these two
The number of plateau training activities increased significantly in 2018.
Reliable sources say that after the future reform of the army, all mobile combat units must have all-region combat capabilities and all services and arms. In the past, the troops were divided into first-line, second-line, and third-line troops according to A, B, and C, and were divided into fully trained troops and semi-trained troops according to the training intensity.
, divided into field troops and garrison troops according to combat tasks.
Nowadays, these complex classifications and gradings have been blurred. In the future, there will only be two types of troops, the border and coastal defense troops and the mobile combat troops. There will no longer be distinctions such as A, B, C, first line, second line and third line, full training and half training.
Any force must have the ability to carry out combat missions in any region.
The Air Force is certainly no exception.
Li Zhan has a lot of experience in plateau flying. When he was in the old army, he almost always flew on the plateau. Later, when he worked in Beiku, he flew many plateau reconnaissance training missions. So he was quite confident.
But man’s calculations are not as good as God’s calculations. Previous weather forecasts showed that the meteorological conditions in the plateau area were good, with more clouds at mid- and high-altitudes but stable activity. Based on the data, the meteorological station judged that cumulonimbus clouds would not form. However, in just two or three hours, the weather in the plateau area drastically changed.
bad.
The regional meteorological observatory is not surprised by this, because it happens often, so they have plans. The problem is that they have no plan for the situation of Black Ribbon No. 01 at this moment.
Who could have imagined that the power system of No. 01 Black Ribbon would go out of control?
Chen Ming reminded Li Zhan in a deep voice, "Dongyao, the weather conditions in the airspace ahead have deteriorated. Cumulonimbus clouds of more than 30 kilometers are forming. You will be violently bumped, and thunderstorms are very likely to appear in the clouds. You must consider
Measures have been taken.”
Li Zhan pondered. At this time, the plane's airspeed was still supersonic, reaching 1,988 kilometers per hour. This airspeed was quite terrifying, more than twice the maximum airspeed of a civil aircraft. At this airspeed, it was slightly more than 1,000 kilometers per hour.
A small pitch angle or side angle will cause a huge overload, and the aircraft may fall apart.
Under normal circumstances, at such a high supersonic airspeed, pilots choose to fly levelly. After closing the distance, they then reduce the airspeed to subsonic. In this way, there is quite a lot of room for movement. When facing the enemy,
As for the fighter plane, it has enough kinetic energy and can completely control the fighter plane.
Li Zhan asked, "Do you have any suggestions for disposal?"
Chen Ming turned his head and glanced at Yi Xiaoyi. Yi Xiaoyi shook his head anxiously and ashamedly. Chen Ming replied, "No, it's over."
Hearing this, Li Zhan said decisively, "We have to adopt the only plan. I calculated that if Hai continues to fly forward for more than 300 kilometers, I can return to the approach distance when the fuel is exhausted."
"Approach distance?" Chen Ming's heart sank.
Li Zhan nodded subconsciously, even though they couldn't see it, he said, "Yes, I can only estimate this accuracy. I will keep flying forward and turn slowly. The turning radius is estimated to be 120 kilometers.
Please do some more calculations and give me a more accurate figure."
Everyone's eyes were on Bao Guanhua. At this time, only Bao Guanhua had the determination to issue this order.
Bao Guanhua stood up slowly and said in a deep voice, "It's not that Li Zhan doesn't have confidence. It can be said that he doesn't have any emotions now. What he gave is simply the data he can calculate. Just follow what he said, just go back to
Everything is easy to say in the second test flight airspace.”
He picked up the microphone and spoke directly to Li Zhan, "Dong Yao, my request to you is to return to the second test flight airspace and be prepared to abandon the plane and parachute at any time. The ground will give you more accurate data as soon as possible."
"Dongyao understands!"
The technicians immediately divided into two parts. One part continued to look for solutions, and the other part immediately calculated the most appropriate flight distance based on the flight data of No. 01 Black Ribbon so that the aircraft could run out of fuel at the right location and land on the runway.
.
Yi Xiaoyi is personally responsible for the second part. He has basically determined that he cannot find a solution in a short period of time. The only hope now is the "almost impossible" emergency landing plan proposed by Li Zhan. There are many plans for this plan, and they are all
He is a great guy in science. He is very good at the triangular relationship between speed, drag, glide rate and distance, etc.
Within a few minutes, Yi Xiaoyi got the first calculation result. After quickly studying the map, he immediately reported to Bao Guanhua: "Director! A third-rate airport is more suitable! I suggest requisitioning their runway immediately!"
Bao Guanhua just glanced at Yi Xiaoyi and immediately picked up the phone and called the military air force duty office directly. After quickly reporting the situation and request, the military air force duty office directly contacted the third-rate airport.
The leader on duty said in a serious tone: "You should immediately stop all entry and exit activities, clear all runways and prepare for emergency rescue!"
Before the third-rate airport could reply in time, the leader on duty hung up the phone and made another call, "Civil Aviation Area Control Center? Our Military Region Air Force Duty Room! I order you to move all aircraft in the controlled airspace away for ten minutes."
Complete the airspace cleanup within 12 days!”
He also hung up the phone without waiting for a reply.
Civil aviation has gone crazy.
The first is the third-rate airport. The airport control center immediately stopped all departing flights and pulled them back to their parking bays. Then it urgently stopped the flights that were entering the port and those preparing to arrive at the final position, and asked them to immediately divert to all but the west side.
Go to alternate airports hundreds of kilometers away in three directions.
A large passenger plane that had entered the landing procedure was an international flight operated by a foreign airline, and most of them were foreigners. The crew hesitated after receiving the tower's instructions. After the tower gave another stern order, the captain quickly changed to the go-around procedure.
.
The large passenger plane with its landing gear only more than 100 meters above the ground suddenly pulled up and climbed, which puzzled the more than 200 passengers in the cabin. The flight attendant's explanation did not satisfy them, but it could not change the diversion to hundreds of kilometers.
The fact of going to an airport outside.
Passengers may find it puzzling that there was no problem with the plane and there was no error in the landing procedure, so why did it have to initiate a go-around at such a critical moment?
This is a global execution issue. No matter what your situation is, unless you encounter an emergency, as long as you have not landed, you must unconditionally leave the designated airspace as quickly as possible. In such an emergency, the command and control personnel do not have time.
To consider the situation of each aircraft in detail, the fastest and most effective way is to use one size fits all!
There is only one purpose - to complete the troops' orders in the shortest possible time!
You must not discount it, if there is any problem, your license will be revoked!
On the civil air traffic control radar screen, dozens of civil aircraft, small planes, and helicopters within the designated airspace are all turning to fly east, north, and south, choosing the shortest route to leave the controlled airspace as quickly as possible.
This kind of large-scale emergency mobilization is a great test of the ability of air traffic control personnel. Otherwise, most of the relevant personnel in the army will be lost during the war. These people can be directly recruited to serve as the air force's air control force. That's right.
The effective supplement of troops is like the crew of a shipping company.
In the third-rate airport, all the flight schedule screens turned red in an instant. Those arriving, departing, already delayed, and scheduled to take off on time, all stopped. In the red information on the screen, the last column
The two words in it made the passengers scared - to be determined.
Passengers who fly all year round know that once a word like this appears, it usually means that delay insurance has come into play, if you have purchased delay insurance.
All announcements in the airport are broadcasting: "Dear passengers, due to air traffic control, all flight activities at this site are suspended. We deeply apologize for the inconvenience caused to you!"
Some sensitive travelers suspected another earthquake, but they didn't feel any tremors!
Soon, all the ground service desks of every airline were surrounded by water, and the departure hall was first in chaos.
At this time, an airport control leader who had been transferred from the Air Force took decisive measures to solve the chaotic problem. He asked the announcer to urgently broadcast a new notice: "Dear passengers, because the Air Force needs to use this airspace for training, there are no flight activities at this site.
Temporarily suspended, the return to normal time is to be determined. We deeply apologize for the inconvenience caused to you!"
"Oh, the troops are training, just wait, wait, stop making noise." This was to advise my colleagues.
"This is air force flight training. If I had told you earlier, this airport is really bad if I didn't explain it clearly!" This is a complaint about the airport's inability to do things well.
"Hurry up with a hammer, An Yiha!" This is a way of scolding others.
Not long after, the airline ground service ladies who were trapped in the sea of people could finally breathe a sigh of relief and breathe much easier.
The order in the terminal quickly returned to calm. Everyone was waiting patiently. Some of them called their wives and said, "My wife, I met the Air Force for training. What, I can't see the Air Force planes."
Silly woman, is that something we ordinary people can see? Do you understand that it is kept confidential? Don't ask blindly. Just wait. It doesn't matter if you change your ticket if you don't have time today.
Some went to the edge of the runway and stretched their necks to look into the outfield and into the sky, trying to see a new fighter aircraft that made people excited. A fact that must be admitted is that since the first flight of the fourth-generation aircraft, the people's pride has become stronger
Now, I have so much confidence that even when I walk hard, there is wind in my body.
The terminal building with 10,000 to 20,000 people suddenly returned to normal conditions.
Li Zhan did not know that in order to ensure that he would not be interfered by any possible unnatural factors in the air, the ground department had already made major moves. At the same time, in order to improve the success rate of the emergency landing, all the runways of the third-rate airport were temporarily requisitioned.
There is only one runway in Chengdu Loma Airport, so there is no other choice. The third-rate airport has two runways, so there is more space and more room. Even taxiing to the taxiway or even a parallel road is better than rushing out of the outfield. Third-rate airports have another advantage.
——After Li Zhan turned around, he had to pass through the third-rate airport before he could return to the main site. In other words, the third-rate airport was closer, even though it was only a dozen kilometers away.
Li Zhan plunged into the cumulonimbus cloud with a width of more than 100 kilometers in the plateau mountainous area at supersonic speed. Below is the plateau with an average altitude of more than 4,000 meters, and the highest peak is nearly 6,000 meters. In other words, after entering the mountain
Li Zhan was only two to three thousand meters high.
Such an altitude gives a normal aircraft a lot of room to maneuver, but for an aircraft whose power system fails and maintains an airspeed of 1,988 kilometers per hour, it is a nightmare.
The visibility dropped instantly, and Li Zhan had to turn on the radar to scan the front hemisphere in order to know the situation ahead and take avoidance measures in advance. When the aircraft malfunctioned, he could not put all his trust in the altimeter. He had to
Make accurate judgments based on comprehensive data from all aspects.
Not long after entering the mountain, Li Zhan clearly felt the fatigue of the turbulence. The airflow was very chaotic. The shaking of the aircraft flying at supersonic speed was more violent than that below the speed of sound. Even if it encountered a strong crosswind, the attitude of the entire aircraft would be destroyed, causing more serious consequences.
Li Zhan's right hand steadily opened the control stick in a small amount, and at the same time he pedaled the rudder carefully, applying force very carefully. He wanted to ensure that the aircraft's attitude was relatively stable while turning, so the control amplitude must be controlled to a very small amount.
Inside.
This is the reason why he needs to fly an extra 100 kilometers to complete the U-turn. In addition, he also has to consider the fuel situation, which makes him have to make a balance between the two factors, and this balance must be very accurate, otherwise there will be
If you run out of fuel but can't fly to the airport, or if you fly too far without running out of fuel, the emergency landing will fail in both cases.
Efforts on the ground are still continuing. Yi Xiaoyi's suggestion of temporarily requisitioning a third-rate airport has another purpose - Li Zhan has an additional airport not far away where he can choose to make an emergency landing.
Chen Ming drew inferences from one example and immediately contacted all airports and air force places within a radius of 50 kilometers, as long as they could take off and land fighter jets. Finally, the temporary requisition was quickly completed through the military area air force duty room.
At this time, Chen Ming felt a little more relieved. He called Li Zhan, "Dong Yao! We have temporarily requisitioned all the airports within 50 kilometers around this field, and the airports within a radius of 50 kilometers are open for you! You can choose any airport for emergency landing according to the specific situation.
!Remember, you have to return to the second test flight airspace to confirm the situation before making an emergency landing!"
Li Zhan understood Chen Ming's intention.
Because of the advanced real-time monitoring equipment, a lot of test flight data will be transmitted back to the ground in real time. Now there is no need to rely on the pilot to use his brain to record the data and feed it back to the technicians. Therefore, there is no need for the test pilot to keep the test flight in order to keep the aircraft.
Data is at your peril.
First, return to the second test flight airspace to confirm that if other failures occur, Li Zhan will have to abandon the plane and parachute. There is farmland there, and there will be no damage to people on the ground. This is the best option in the final plan.
The problem is that reality is often cruel.
After learning that there were more emergency landing airports to choose from, Li Zhan himself was slightly relieved. He had already memorized the terrain in the area and knew the locations of those airports. Of course, no matter from any aspect,
It seems that third-rate airports are the best choice.
However, it seemed that he had no chance to fly out of that large plateau cumulonimbus cloud so smoothly.
