Chapter 29 Tire Blowout
On the tower, a large group of people were staring at the radar screen, another group of people were leaning in front of the window with bated breath, and some were observing Feiyu 6321 with telescopes.
"Not high enough!"
"No, they can't land."
"Ruined!"
From the tower's angle, it is actually impossible to see the relative height of the plane above the ground, but combined with the data from the radar, we can roughly see the situation of Feiyu 6321.
Even a semi-layman like Qin Xin could understand it, so how could the tower controller not understand it? At first, the tower control room was gloomy. But just like Qin Xin's reaction, when Feiyu 6321 encountered an updraft and was strangely lifted, the tower control room suddenly became a little popular.
However, the most exciting and amazing operation at the leveling altitude could not be seen by the controllers due to the angle, so naturally there was no such shocking feeling as Qin Xin saw with his own eyes.
The antelope hangs its horns, leaving no trace! This move alone is enough to become a textbook operation.
However, all the attention of these tower controllers was attracted by the moment when the plane touched down. The plane's air-ground logic sensor was installed on the main landing gear. As long as the main landing gear was compressed, the plane's air-ground logic was switched and displayed on the radar.
"It's landed! Hahaha, it's landed!" The controller in charge of Feiyu 6321 had been sitting in front of the radar screen. When he saw the air-to-ground logic transition of Feiyu 6321, he almost jumped up and immediately shouted to his colleagues who were observing visually at the window: "It's landed, right? It's landed, right?"
The colleague holding the telescope by the window grinned to his ears and laughed loudly: "It fell down, it fell down! No…"
The cheerful atmosphere in the control room suddenly shrank with a cold shout. The controller pushed the crowd aside and rushed to the window. He observed the situation on the runway with his naked eyes and found that Feiyu 6321 was still on the runway. He couldn't help asking, "What's wrong? What's wrong?"
"When the plane touched down, there seemed to be unusual smoke rising." My colleague was actually not sure in his heart.
"Doesn't it often happen that smoke appears when the wheels of an airplane touch down?" the controller inevitably asked.
The wheels of the aircraft's landing gear do not rotate by themselves, so at the moment of touchdown, the tires will first rub against the ground, and then the friction will drive the wheels to rotate. The friction at the moment of touchdown will easily produce a large amount of white smoke, which is not a rare scene, and even the controller should know it.
My colleague touched his head. He knew that the landing gear wheels of an airplane would often produce smoke when it touched the ground, but this time it felt a little different from before, but he couldn't tell what the difference was exactly.
However, another colleague soon discovered something unusual: "No! Why didn't the plane slow down?"
"What did you say? " The controller's scalp suddenly felt numb. Could something really have gone wrong?
In the cockpit, the captain had just manually pulled up the speed brake handle and was still cursing: "What was that sound just now? Did the tire blow out?"
Why is happiness too much and then comes sorrow? The captain finally knows!
Just now, a muffled sound was suddenly heard in the cockpit when the plane touched down, and then the taxiing direction after landing began to become unstable. Fortunately, Xu Cang's correction was very timely, which prevented the danger of running off the runway.
However, the captain soon discovered that the aircraft did not seem to be slowing down. At first, the captain thought that the automatic brake did not work because of the hydraulic system problem caused by the double engine flameout. But in fact, even if the engine-driven pump of the AB system cannot be used, the hydraulic pressure generated by the electric pump can theoretically make up for the remaining required hydraulic pressure.
Of course, nothing is absolute, and theories are never the golden rule. For example, when the hydraulic consumption is extremely high, the electric pump may not be enough and the hydraulic pressure may be low. In such extreme cases, the automatic brake may not work if the pressure is not stable.
But if the automatic brake does not work, its arm release light should light up, but the automatic brake arm release light did not light up from beginning to end.
Obviously, Xu Cang also found the problem. He naturally heard the muffled sound after the grounding. Although there was no abnormal indicator light, he roughly figured out what was going on.
The automatic brakes could not cope with the current situation, so they switched to manual brakes. Without any pause, Xu Cang directly stepped on the automatic brakes, and as the automatic brake release pre-position light came on, the plane switched to manual brakes.
From the time the plane touched down to now, it has hardly slowed down, and too much runway has been wasted. The remaining runway cannot be wasted at will.
The current Jianchuan Airport's runway is not as exaggerated as the ones in later generations that are over 4,000 meters long, but it is just 3,200 meters, which is definitely the standard for a branch airport runway in later generations.
In just a blink of an eye, the plane had already used more than half of the runway. Xu Cang no longer hesitated and stepped on the brake pedal. It is taboo to use the brake pedal when braking an airplane, especially at high speeds. Not only will it accumulate a large amount of heat in a short period of time, making the brake pads overwhelmed, but the braking effect will also be quite poor.
Therefore, if you want to stop the car as quickly as possible, press the button as hard as possible and don’t let go!
At the same time, in addition to the captain pulling up the speed brake, Xu Cang also pushed the steering wheel to the bottom to increase the friction of the main landing gear wheels. As for the engine reverse thrust, since both engines were turned off, it made no difference whether it was pulled up or not.
"Stop!" In Xu Cang's field of vision, the business jet apron next to the end of the runway was already very clear. He could even see a business jet on the apron leaning against a passenger elevator with two people standing on it.
But he could feel that after the initial rapid speed decay, the braking effect began to become worse and worse. This was because the brake pads were overheating, and there was even a risk of the brake pads melting.
Right in front of Feiyu 6321, Qin Xin watched the plane rushing towards her. Although strictly speaking, they were not on the plane's taxiing path, the large amount of smoke rising from the landing gear of the plane always gave people a terrifying feeling of a tsunami, as if the plane was about to explode in the next moment.
Her secretary was afraid and whispered, "Miss, why don't we go down and walk a little further away?"
"It's okay!" Qin Xin didn't have the slightest thought of leaving. Her beautiful phoenix eyes were fixed on the plane that was getting closer and closer. Suddenly, a hint of joy appeared on her face: "It seems that the plane can stop."
