On the business jet apron near the head of Runway 23 at Jianchuan Airport, a handsome white-painted Gulfstream business jet has completed all preparations before takeoff and is waiting for the approaching take-off time.
Since every flight of a business jet requires approval, the take-off time is fixed and cannot be advanced. There is no way, the boss came too early, so I can only wait.
In the cockpit, two pilots slumped in their seats in boredom. Normally, they should have chatted about anything under the sun, but the cockpit door was open, and it would be bad if they chatted too much and were heard by the boss behind them.
Business jet pilots have a relatively easy life, with an estimated workload of only a hundred hours a year. Compared to airline pilots who often work nearly a thousand hours, they are not very healthy.
Unlike airline pilots who are paid hourly, business jet pilots have a fixed salary. If business jet pilots are also paid hourly, they will earn nothing after flying more than 100 hours a year. Therefore, business jet pilots are basically paid on a buyout basis, and they only make so much money a year, regardless of how much they fly.
In terms of cost-effectiveness alone, business jets are quite high and are a very good place for pilots who like to spend their days lazing around.
Just when the two pilots were getting bored, a voice suddenly came from the clearance frequency: "N254DC, transfer to 121.55, frequency test."
Because every flight of a business jet requires special approval, there is definitely no regular flight number, so the call sign is usually replaced by the aircraft number.
The pilots looked at each other in bewilderment, but the co-pilot on the right seat still complied with the clearance control's request and switched the frequency to 121.55: "Clear, N254DC!"
"N254DC, which signal do you want to hear?" Soon the controller's voice came from the headset.
"Five!"
"Okay, now you can switch back to the release frequency 121.7."
The co-pilot did not turn back immediately, but asked in a slightly surprised tone: "Excuse me, why are you suddenly doing a frequency test now?"
Generally speaking, frequency testing is done in the morning when the frequency is reopened, but what time is it now? Do we still need to open a new frequency?
Large airports like Jianchuan have various frequencies for approach, tower, ground, apron, release, on-site command, etc. However, in the early morning, there are few flights, and it would be a waste if all these frequencies were running as usual.
Normally, the approach frequency is fixed, but the tower frequency is sometimes combined with the clearance frequency, and the ground and apron frequencies are combined to properly allocate resources.
Starting from 6 a.m., as the number of flights increases, the closed frequencies will be reopened one after another. When they are reopened, the controller will randomly select a crew to conduct a frequency test.
It is indeed rare to see frequency testing in broad daylight.
The crew in the business jet is also bored. This is not something the pilots should be concerned about. If the airport wants to test the frequency, it can test it. Do they have to report to the crew?
However, the airport did not hide it and said directly: "This is the airport's backup frequency, which will be activated soon. N254DC will switch back to 121.7 for long-term use."
"121.7, N254DC!" The co-pilot did not ask any more questions. After switching back to the frequency, he reported: "Clear, 121.7, I'll hold with you."
"N254DC, hold the frequency!" The release frequency continued: "All aircraft on the frequency are prohibited from using the 121.55 frequency in the next hour. I repeat, it is prohibited to use the 121.55 frequency in the next hour!"
The same words appeared not only on the release frequency, but also on the apron, ground and tower frequencies. This was not directed at a certain crew, but a broadcast-style shouting to all aircraft.
"121.55?" The co-pilot was a little confused: "What's wrong with this frequency? It seems like something has happened."
The captain also showed a thoughtful expression: "Some crews chat in 121.55. It seems that the airport will temporarily use 121.55 alone. It's a bit strange."
Sometimes when flying, you can hear familiar voices on the radio, but it's okay to chat for a few words on the controlled frequency, but if you chat too much, it will annoy people and you may even be sued by the control unit. Emergency frequencies are usually not crowded, but occupying them doesn't seem to be a good idea.
Therefore, smart pilots will agree on some chat frequencies. For example, airlines have their own agreed frequencies, and airports also have corresponding frequencies, such as the backup frequency 121.55 of Jianchuan Airport.
Many familiar pilots chatted in 121.55 when they met at Jianchuan Airport. Jianchuan Airport must have known about it, but they didn't care. It was only at special times that they specifically reminded the crew not to call 121.55, which was quite humane.
While the co-pilot was still wondering what was going on, his eyes suddenly narrowed. The nose of the plane was facing runway 23, and it was very close. He clearly saw that the runway lighting system, which was originally at normal brightness, suddenly became brighter, and was extremely conspicuous even under the sun.
"No, what does the airport want to do? The brightness is so bright that it's blinding." The co-pilot muttered.
The higher the light brightness, the better. If it is too bright, it will affect the pilot's judgment of the relative position of the aircraft, which is extremely disadvantageous. In the case outside, the light is obviously adjusted to the highest brightness, but this kind of operation is only possible in low visibility conditions. How can this be done in broad daylight with no clouds?
"It's so strange, it's really so strange." If the captain still couldn't find anything unusual, then his work was in vain. He showed a hint of excitement and urged the co-pilot: "Use the second unit to dial the tower frequency and listen to see if there is really an accident."
The co-pilot was also very curious and hurried to check the tower frequency. However, suddenly, the two seemed to notice something and turned around to see Qin Xin standing at the entrance of the cockpit. The expressions on their faces froze.
Qin Xin asked coldly, "What happened?"
…
At this moment, the crew car carrying Luo Yong, Yu Fengtian and others has successfully passed the security check. The airport has greeted the security checkpoint and the clearance was very smooth.
After passing the security check, the crew car took Luo Yong and others all the way to the bottom of the tower. The area near the tower is a restricted area, and the crew car cannot drive in, so it can only stop nearby to let everyone get off.
The airport sent someone over to greet Luo Yong as soon as he saw him coming over: "Mr. Luo, you're here quickly. Thank you for the trouble."
"No, no, Director Liu is worried about our own business ." The person who came to pick them up was the director of the control tower, whom Luo Yong knew. Sometimes, airlines would socialize with airport groups to improve their relationship. Luo Yong still knew some people in the airport, but his personal relationship was not very good.
Director Liu glanced at Yu Fengtian, Li Rongcheng, and Ye Xian who were following behind him, and said, "There are quite a few people."
"This is our company's vice president of maintenance, and the two people behind him are Boeing staff. As you know, we wet-leased this aircraft from Muhua, so we don't know much about it. To be honest, we don't even know whether we can help." Luo Yong said worriedly.
Director Liu expressed his understanding of this point. Even for giant companies like the three major airlines, the number of Boeing 747s is not large, far less than the 737 fleet.
The fewer the number, the less experience you have. When it comes to airplanes, you can’t just study the manual and understand everything. It’s all based on the experience gained from running a large number of flights.
"It's okay. We'll do our best." Director Liu said as he walked with Luo Yong, "According to the crew report just now, in addition to the captain and co-pilot on duty who were in a coma, there were also three passengers injured in the cabin. The situation does not seem to be serious."
"That's good, that's good!" No matter what, people are always the most important. As long as they are fine, many issues can be discussed. But once something happens to a person, even if the plane is fine, it is a big deal.
Everyone followed Director Liu and took the ladder to the dispatch room on the top of the tower. During the time, Director Liu was a little surprised: "We just received a message from the Qianzhou District Dispatching Office. The crew asked us to open a separate communication frequency and turn all the runway lights to the brightest. Mr. Luo, do you know why?"
To be honest, it is understandable that a separate communication frequency was opened. It may be that the crew has too much work and does not want to waste time on communication. However, it is strange to adjust the runway lights to the brightest level. The highest level of brightness is extremely dazzling even in the daytime, which is not conducive to the pilot's landing.
Luo Yong thought for a moment but couldn't figure out what Xu Cang wanted to do. It was indeed very strange to turn the lights to the brightest.
When everyone got to the dispatch room, they could see most of Jianchuan Airport through the glass, and the brightened runway lights were extremely dazzling, even from a long distance away.
Luo Yong couldn't help but frown: "It's too bright. Can I see the runway clearly when I land?"
As he spoke, Luo Yong looked at Director Liu in confusion: "Are you sure that the unit requires the highest level of brightness? Did you hear me correctly?"
"I'm sure I heard it right. I also found it strange, so I asked you."
At this moment, a control seat next to Director Liu said, "Director, the communication has been transferred!"
"Hmm?" Director Liu was stunned: "Give me the microphone!"
Everyone realized that 9811 had connected to the airport frequency and immediately surrounded the control seat. The signal point of 9811 could be seen on the radar screen. It was less than 30 nautical miles away from the airport and had entered the approach area and would land soon.
"Blue Sky 9811, now under radar guidance, blind landing on No. 23, can we fly heading 030 now?" Director Liu said quickly.
There was silence on 9811 for a long time. Just when everyone was getting impatient, a woman's voice answered: "No, we apply for a procedure-based approach to pick up SXS-1Y."
Director Liu was stunned. He remembered that the information he got was that the current operator of the plane was Xu Cang, so he should be a man. Why did the answer say it was a woman?
However, he didn't pay much attention to it. It might be that Xu Cang was too busy and asked the flight attendant to help with the communication. It was not that uncommon. However, he didn't quite understand why they had to land according to the standard approach procedure. Obviously, the radar guidance should be faster.
Considering that it might involve flight issues, Director Liu did not give an immediate answer, but looked at Luo Yong.
Luo Yong grabbed the microphone and said, "The SXS-1Y approach requires a long final approach, which takes too long. We need to land quickly. Follow the previous instruction and fly heading 030. The radar will intercept the blind landing."
However, this time the answer came much faster, and it was the same woman's voice: "No, we can only fly a standard instrument procedure."
Luo Yong was already furious, and he couldn't figure out what Xu Cang was up to, so he yelled, "You want to have more fun in the sky? Don't let a flight attendant talk to me. Where's Xu Cang? Give me a reason, why do you fly the standard approach procedure?"
After another silence, the other party spoke again: "Mr. Luo, I am Xia Shuyue from the Second Crew Squadron. My brother said that he can't see now and can't follow the instructions to accurately control the plane. He can only fly according to the standard approach procedure."
As soon as these words came out, everyone was in an uproar. Luo Yong was shaking all over, and a layer of cold sweat oozed out of his back. He and Director Liu looked at each other in bewilderment. They hadn't said before that even Xu Cang's health was in trouble!
Obviously, Director Liu was also hearing this news for the first time, and a trace of panic appeared on his face. How could the pilot land the plane if he couldn't see?
"What's going on? Where's Xu Cang? Let him talk to me!" Luo Yong was so angry that he raised his voice unconsciously.
"Mr. Luo, my brother had bleeding in his eyes when he was relieving stress." Xia Shuyue continued, "Also, his ears are bleeding, so his hearing is very poor. Sometimes he needs me to repeat it to him. If possible, can you please make it brief, otherwise I may not remember it."
"This..." Luo Yong's hands could hardly hold the microphone. He supported himself on the stage with one hand, trying to steady himself and stay calm in the face of such shocking information.
A blind and half-deaf person trying to land a giant passenger plane, is that a joke?
Yu Fengtian, who was standing outside, almost collapsed to the ground when he heard the news that Xu Cang could not see or hear anything. This was basically a death sentence for the plane. If the plane crashed and it was finally found that the source of everything was the defect of the S2 switch, then he would not just have to hand in his resignation.
It was Ye Xian who showed a look of surprise, while Li Rongcheng had a blank expression on his face, and no one knew what he was thinking about.
As if he had grasped a glimmer of hope, Luo Yong quickly said, "Xu Cang, tell the flight attendant to switch to automatic driving. Is she okay?"
Now the frequency became completely quiet, so strange that it made people feel a little scary.
Suddenly, a cold voice rang out on the frequency: "You want me to hand over the entire plane to a flight attendant who knows nothing? Do you trust her, or do you trust the 747's automatic landing function?"
In fact, Xu Cang had considered letting Xia Shuyue control the plane instead of him, after all, the autopilot could still be used. However, after thinking it over, Xu Cang rejected this idea. Not to mention whether Xia Shuyue could understand his command, he hadn't even made the approach preparations yet. If he wanted to approach automatically, he not only needed to adjust the MCP board, but also set the localizer, decision altitude, navigation frequency, etc. He didn't have time to do any of these.
If any of these links went wrong, the plane would be doomed. Xu Cang couldn't see it now, so he couldn't verify whether Xia Shuyue was right or not. The risk was too great, so great that Xu Cang had already considered it impossible.
Moreover, another reason Xu Cang opposed letting Xia Shuyue come was the poor automatic landing function of the Boeing 747. If Xia Shuyue came to approach, she would definitely land automatically, but as far as Xu Cang knew, the automatic landing of the 747-400 was not perfect yet, and it would take many versions to be relatively reliable. How could Xu Cang pin his hopes on an unreliable automatic landing function?
Luo Yong shouted, "Then how are you going to land? How can you land if you can't see? Not to mention leveling off, you can't even guide the plane over the runway!"
After waiting for a while on the frequency, Xu Cang replied: "So, I need to fly according to the standard approach procedure. I will use vertical navigation to guide the aircraft to the runway."
"No!" This shout came from Director Liu. He took Luo Yong's microphone and said, "Xu Cang, are you talking about RNP APCH? But the PBN operation is still in the testing state. The regional navigation routes on the route have not been fully released, let alone the RNP1 part of the approach phase. Xu Cang, our airport does not have RNP procedures. If you want to fly using vertical navigation, it cannot guarantee safety."
"It's okay!" Director Liu's voice was so loud that Xu Cang could understand it without Xia Shuyue's retelling: "Even if there is no RNP procedure, the FMC will calculate and simulate a descent profile during the final approach, and we will fly according to that."
"But that has not been verified." Director Liu obviously knows some cutting-edge PBN technology: "The descent profile calculated according to B-VNAV does not match the blind landing glide path, and is greatly affected by temperature, and there are terrain risks."
"It's okay, it's safe!" Xu Cang's attitude was extremely firm.
Of course he knew it was safe, because Boeing verified this technology for a full decade and only promoted it to the world after confirming it was absolutely safe. This is the RNP APCH commonly used in later generations and the more advanced quasi-precision RNP AR technology.
However, this technology is still in the testing stage around the world. Two years ago, Europe first tried to use basic area navigation technology, and China has only tested PBN technology on a few routes.
For example, the point P554 given by Qianzhou Control just now was located by PBN technology.
Traditional routes are based on navigation stations, and because of the necessity of navigation stations, the airspace utilization of routes will be greatly restricted. However, PBN technology uses the WGS84 coordinate system as a navigation method, and defines a waypoint by longitude and latitude, so it is not restricted by navigation stations.
In this way, the utilization rate of airspace will be greatly improved. Of course, in this era, few people can understand this technology, and it is rare for Director Liu to know a little about it.
"This..." Seeing Xu Cang's extremely firm attitude, Director Liu didn't know what to say, so he could only look at Luo Yong and ask for his opinion.
Luo Yong gritted his teeth as he took the phone: "Xu Cang, even if you can guide the plane over the runway , how can you level it? This approach method cannot be connected to an automatic landing."
Automatic landing can only be continued with the blind landing approach, so the final leveling action cannot be completed.
"I don't plan to use automatic landing either." After waiting for a while, Xu Cang's attitude became even more unshakable: "Just use vertical navigation to guide the plane to the air above the runway. As long as it is guided there, I can land. That's it!"
"Damn it!" Luo Yong put his hands into his hair. He felt a splitting headache. This kid Xu Cang was as smelly and hard as a stone in a toilet.
However, Li Rongcheng at the back had a gleam in his eyes. He didn't expect that Xu Cang was so familiar with PBN, an extremely cutting-edge navigation technology. This was quite rare.
…
At this moment, in the cockpit, Xu Cang threw away his headphones, let out a long breath and confirmed with Xia Shuyue again: "Do you remember the airspeed, altitude and heading I taught you just now? Do you know where it is?"
"Yes, I know. The airspeed indicator is on the left, the altimeter is on the right, and the heading indicator is at the bottom. It's like a compass. Remember it." Xia Shuyue nodded.
Xu Cang let out a long sigh of relief. This was the limit of what Xia Shuyue could understand. Just now, Xu Cang spent a long time to make Xia Shuyue understand where the airspeed indicator, the altitude indicator, and the heading indicator were. Just reading these basic data consumed almost all of Xu Cang's energy. Luo Yong actually wanted him to teach Xia Shuyue how to approach again, which was ridiculous.
If it were so easy to learn, pilots wouldn't be so valuable!
The reason why Xia Shuyue had to read the airspeed, altitude and heading data was that even though the horizontal and vertical navigation could guide the aircraft to the runway and even automatically adjust the speed, the establishment of the landing configuration had to be done manually. Xu Cang could do this himself.
Although you can't see it, just lower the landing gear handle. There is a slot on the flap handle, so you can roughly know how many flaps there are by touching it.
Xu Cang needed to confirm the airspeed to establish the landing configuration, and verify the altitude and heading to verify that the aircraft was indeed flying according to the standard instrument approach procedure.
Suddenly, Xu Cang felt a strange feeling in his heart. After switching to the Jianchuan Airport frequency, the plane should be very close to the airport, probably only twenty or thirty nautical miles away.
I just talked to the controller and according to the speed of the plane, we should turn to the third right now.
According to Xu Cang's memory, the aircraft should have approached the airport from the direction of Xishan, with its heading exactly towards this airport. Then, at about twelve nautical miles away from this airport, it turned right and joined a right third leg, flew to the initial approach positioning point of SXS-1Y and joined the approach procedure.
It feels like we should turn right now.
"Shuyue, where are we flying now?" Xu Cang asked.
Xia Shuyue studied the navigation page for a long time and said uncertainly, "It seems to be heading towards a small green circle."
Xu Cang's heart skipped a beat. That small green circle was exactly the location of Jianchuan Airport, and he had typed it in himself. He asked anxiously, "Is the plane still following the red line now?"
The red line represents the effective route and approach procedure. As long as the aircraft is still on the red line, it means that there are no problems with the aircraft for the time being.
However, Xia Shuyue said, "Brother, it's gone! It just flew towards the small green circle."
Xu Cang's face changed drastically. He held the steering wheel tightly with his left hand without saying a word.
Xia Shuyue thought that her voice was too soft and Xu Cang’s hearing was damaged so he didn’t hear her, so she said louder, “Brother, we didn’t fly along the red line.”
"I heard it." Xu Cang took a deep breath, but Xia Shuyue beside him could hear that Xu Cang's breathing was slightly trembling. He patted Xia Shuyue and said, "Hurry up and contact the control department and ask them to locate us."
Xu Cang didn't understand why the plane didn't fly according to the procedure based on the horizontal navigation. He only knew that the plane had deviated from the procedure, so the RNP APCH that followed was all empty talk. He didn't even know where the plane was now.
Xu Cang can't expect Xia Shuyue to understand the contents on the navigation page.
Although she didn't understand what happened, seeing Xu Cang's serious expression, Xia Shuyue probably knew that the situation was not good, so she called the control. However, after calling several times, the other party did not respond.
"Brother, they didn't come back!?" Xia Shuyue was a little nervous.
Xu Cang was also a little panicked at this time. If the communication failed again, without the help from the ground, they would undoubtedly be in a worse situation. Xu Cang stretched out his right hand, fumbled on the communication panel for a long time, and switched the transmitter by feeling: "Try again."
Xia Shuyue nodded and called a few more times, but still no response.
Xia Shuyue was really panicking now: "Brother, there is no sound, what should I do?"
At this moment, even Xu Cang felt a trace of despair in his heart. Recalling it, perhaps when he was inputting the CDU just now, because he was worried about temporary blindness, he accelerated the input speed and did not connect the last point of the route with the starting approach positioning point of the approach procedure, which caused the disconnection and the aircraft deviated from the procedure.
Of course, the reason is no longer important; what matters is what to do now?
Once the plane deviated from the procedure, Xu Cang didn't even dare to descend, because flying according to the procedure was protected by the terrain, and there would be no problem as long as he lowered the altitude step by step according to the height limit in the procedure.
But now it was out of procedure, and Xu Cang didn't know what was below. What if he randomly descended and crashed into the mountain? If he wanted to deviate from the procedure and descend, he needed permission from the controller, because the controller could see the impact of the terrain and would help the crew evaluate it. However, now he couldn't even contact the control, and he was really desperate.
Not to mention flying over the runway, he didn't even know where he was now!
"Am I really going to die here this time?" This thought appeared uncontrollably in Xu Cang's mind.
Even though she didn't understand the current situation, Xia Shuyue could feel Xu Cang's expression change. She couldn't help but ask, "Brother, what should we do?"
Xia Shuyue's voice was getting weaker and weaker. Xu Cang knew that his hearing was still declining and he would not be able to hear anything soon. By then, he would be doomed.
It's time to make a decision!
"If there is no procedure, then I will calculate one!" Xu Cang gritted his teeth. He had too much on his back, and he couldn't just die here so easily!
Relying on the airspeed, altitude and heading that Xia Shuyue could provide and the approach procedure diagram in his mind, Xu Cang was trying to figure out an approach procedure in this desperate situation!
Well, first he needs to know where he is!
"Keep flying forward!" Xu Cang said coldly.
Xia Shuyue was startled: "Where are you flying to?"
Xu Cang took a deep breath: "On that small circle, let's start from there!"
…
At this moment, in the control room of Jianchuan Airport, everyone gathered around the radar screen and watched the signal point 9811 fly along the SXS-1Y procedure. However, at the turning point of the right third leg, the aircraft did not turn right to the initial approach fix point, but kept flying forward on the heading.
"What's going on? Why didn't the plane fly according to the procedure?" Director Liu was stunned and patted the controller on the shoulder: "The crew just said to follow the SXS-1Y procedure, didn't I hear it correctly?"
"Director, the crew just said that they would approach according to SXS-1Y," the controller confirmed.
"Then why isn't he turning?" Director Liu pointed at the controller's microphone and said, "Call the crew and ask about the situation."
However, before the controller could speak, Xia Shuyue's voice rang out: "Tower, Blue Sky 9811!"
Director Liu quickly patted the controller on the shoulder and said, "Go back quickly and ask them if they have changed their intention to enter the airport."
The controller nodded and immediately asked into the microphone: "Blue Sky 9811, you have now deviated from SXS-1Y. Do you want to change the on-site procedures?"
Now everyone around listened attentively, but after waiting for a while, the crew did not respond at all, and continued to ask: "Tower, Blue Sky 9811, can you hear me?"
"Blue Sky 9811, I hear your signal five." The controller replied immediately.
However, it was Xia Shuyue's slightly nervous voice that responded to the controller: "Tower, please reply if you hear me. We want to confirm the location of the plane."
Three times the limit, everyone, including Li Rongcheng and Ye Xian in the back, looked very upset. Luo Yong was stunned for a long time, and then he said in disbelief: "They...the receiving antenna has a problem?"
The control side can hear the crew's voice, but the crew cannot hear the controller's response, which basically concludes that the aircraft's receiving equipment is malfunctioning.
In fact, it is also possible that there is a problem with the transmitter on the control side, but the probability is too small.
With the crew unable to see and almost unable to hear, and the aircraft's receiving antenna malfunctioning, that meant the crew received no help from the controller.
What's worse is that now that the aircraft has deviated from standard procedures, the autopilot will be unable to guide the aircraft to the predetermined position over the runway.
"They just asked us to report the location of their plane, which means..." Director Liu looked at Luo Yong with horror: "The crew doesn't know where they are now!? How could this be? The plane should have navigation instruments!"
Yu Fengtian's teeth were almost bleeding: "But the people who can understand the navigation instruments can't see them now!"
"No, no, no, no! This won't work. We can't see the plane visually and can't see the instruments. How can we land the plane? Are we flying blind? Luo Yong, Luo Yong! You better find a solution!" Director Liu almost collapsed. He had worked in the control tower for ten years and was about to be promoted to the Air Traffic Control Bureau. He couldn't allow a flight accident to happen during his tenure. Otherwise, his career would be over!
Luo Yong's face was ashen. How could he think of a solution? What solution could he have?
Director Liu saw Luo Yong was helpless and became furious. He grabbed Luo Yong by the collar and shouted in a low voice: "In one month, I will be transferred to the Air Traffic Control Bureau. If your company did this before I was transferred, and I am ruined, you will not have a good life!"
Luo Yong's face suddenly changed. Seeing Director Liu's expression as if he wanted to eat him alive, he knew that Director Liu was not joking. If Flight 9811 really crashed today, as the director of the tower dispatch room, it would definitely be a big stain on his career, not to mention being responsible. It would be wishful thinking for him to want to join the Air Traffic Control Bureau again.
Luo Yong knew that Director Liu had been waiting for ten years to be transferred to the Air Traffic Control Bureau, and now his dream was shattered. All Blue Sky Airlines planes departing from Jianchuan Airport would be in great trouble!
"Director Liu, you can't do this. We don't want this to happen." Luo Yong quickly explained.
"What about me?" Director Liu roared, "I can't care about that. You have to take responsibility for what happened in your company! If this plane is smashed, if there are any delays or flow control in the future, your Blue Sky Airlines will be the last one!"
Director Liu's roar almost filled the entire control room, and what he said was clearly a personal revenge, which was extremely inappropriate. But the controllers in the control room all lowered their heads and pretended not to hear it.
After waiting for ten whole years, to be disappointed in one day, anyone would go crazy!
Luo Yong's face instantly lost color. There is no airline that is unwilling to maintain a good relationship with the director of the airport tower dispatch room. Even companies like the three major airlines will send various gifts to the dispatch room during holidays and invite guests to dinner from time to time, just to maintain the relationship with the dispatch room.
As a result, Blue Sky Airlines failed to maintain a good relationship and directly offended the person in charge of the dispatch room. In the foreseeable future, Blue Sky Airlines will have difficulty in operating at Jianchuan Airport.
"Change to 121.5 and continue calling!" Director Liu had already made the harsh statement and was too lazy to argue any more, so he asked the controller to try calling the 9811 crew on the emergency frequency.
However, before the controller could speak, the 121.5 emergency frequency could be heard the deep and cold voice of Xu Cang: "Blue Sky 9811 communication failed and now blindly sending information! This aircraft is expected to land at Jianchuan Airport in ten minutes. Due to vision and hearing problems of the operators on board, and the navigation equipment cannot be used, all aircraft on Jianchuan Airport A taxiway, all departure paths, and runways are requested to leave as soon as possible! I repeat, due to vision and hearing problems of the operators on board, and the navigation equipment cannot be used, the landing accuracy cannot be guaranteed. All aircraft on Jianchuan Airport A taxiway, all departure paths and runways are requested to leave as soon as possible and stay away from the corresponding area."
As soon as this was said, the whole dispatch room was in an uproar. During the communication failure, if it was only a one-way failure, it was possible to try to send a blind message to inform the controller of the intention. The 121.5 emergency frequency is monitored by all aircraft and control units, and the blind transmission range is the widest on this frequency.
Xu Cang didn't have time to verify whether it was a two-way communication failure or a one-way communication failure. He just did everything he could.
Blind launches are not rare in themselves, but the content of the blind launches is terrifying. Director Liu muttered in a daze: "What does that mean? Is he prepared to crash?"
The runway and the taxiway adjacent to the runway must be cleared, which clearly shows that the crew no longer has the confidence to land on the runway. It means that all people and aircraft in the nearby area must be evacuated to avoid harming innocent people.
This is very bad news, and it seems that the crew is in a desperate situation.
Luo Yong and Yu Fengtian looked at each other, and both saw endless fear in each other's eyes. As long as this plane crashed, Blue Sky Airlines would also be finished.
There is no need to care about personal grudges now. Yu Fengtian hopes that Xu Cang can land the plane more than anyone else.
Director Liu let out a long sigh. He really wanted to curse and vent his anger, but he knew there were more important things to do.
He turned around and pointed at his assistant: "Notify the release and apron departments to suspend the pushback of aircraft, and have the ground staff recall all the aircraft that are taxiing. Also, the airport fire department and emergency medical services, hurry up!"
After saying that, Director Liu glared at Luo Yong fiercely, his meaning was self-evident.
…
At the same time, on the Gulfstream business jet, Xu Cang's blind message was also received, and Qin Xin, who was standing at the cockpit door, listened to every word.
The two pilots present did not notice that Qin Xin's face was rapidly darkening, and they were still discussing the content of the blind transmission.
"Why is it that the crew has hearing and vision problems?" The captain was a little surprised: "Could it be that the airport uses the backup frequency exclusively for him?"
The co-pilot clicked his tongue and said, "Brother, this guy said the navigation equipment is not working. How can we land this plane? We can't see or hear anything, and the navigation equipment is not working. How can we do this?"
"What else are you doing?" The captain sneered, "They are dead. I don't know how they got into this situation!"
However, just as the captain finished speaking, there was a sudden noise from behind. The captain and the co-pilot, who were chatting animatedly, were startled to realize that Qin Xin was at the door.
When the captain turned around and looked at Qin Xin with a dry laugh, he saw that Qin Xin's pretty face was pale and her whole body exuded a chilling aura.
"Boss?" The captain instinctively felt that something was wrong with Qin Xin's condition.
"Can you find the flight crew information of Blue Sky Airlines?" Qin Xin asked in a low voice.
"Well..." The captain was a little nervous: "To check the flight schedule of an airline, you need employee privileges. I can't check it. However, I know someone at Blue Sky Airlines who can help me check it. Boss, what do you want to check?"
Qin Xin's voice became colder and colder: "Blue Sky 9811!"
…
Xu Cang's blind message was transmitted through the emergency frequency to almost all aircraft and control units in the country, and the information revealed in it made those who heard it extremely surprised. Someone actually landed without being seen, heard, or having any instruments. This was simply an impossible thing that exceeded human limits.
However, countless crews still began to inquire about Blue Sky 9811. Everyone, everyone was paying attention to this epic performance!
The dispatch room at Jianchuan Airport was filled with a solemn atmosphere. The landline phone on the duty desk had been ringing ever since Xu Cang sent the blind message, but Director Liu refused to let anyone answer it.
He knew who was calling and what they wanted to ask without even answering the phone.
Even if he answered the phone, if the plane crashed, he would still end up in the same situation. The only thing that could save him now was if 9811 could land safely.
But looking at Luo Yong and Yu Fengtian who were sweating profusely, Director Liu's last bit of fantasy was shattered.
No sight, no sound, no instrument!
Director Liu sighed. Without instrument navigation and visual reference, how could the plane fly to the final approach? Without program protection, the plane could not descend at all because it could crash into the mountain at any time! Even if it flew to the final approach and flew over the runway, it could not see the runway and could not hear the radio altimeter's report. How could the plane level out?
Director Liu was faced with a series of unsolvable problems, which repeatedly spoke like the devil's whispers about the inevitable outcome.
Li Rongcheng, who had been silent, looked solemn. He exhaled lightly, "Xu Cang, what would you do?"
"How and where are they going to fly?" Director Liu asked feebly. He didn't know who to ask. Now the crew didn't even know where they were. It was a dead end.
"They are flying to the airport!" Suddenly, a voice filled with excitement rang in everyone's ears. It came from Ye Xian, who had not spoken for a long time.
He licked his dry lips and stared at the radar screen: "They don't know where they are, so they have to locate themselves first, and the airport is their location!"
“But even if they fly to the airport, how will they fly afterwards, without any instrument support and visual reference!” Director Liu asked.
However, Ye Xian was trembling all over: "There is no instrument or visual, but he has airspeed and heading, so he can calculate a way!"
Ye Xian's eyes burst into an incomparably bright light, and the blood in his body seemed to be boiling. He could hardly hold back and let out a long roar: "Xu Cang, can you do it? Can you achieve this miracle that transcends human beings?"
