Star Travel Flight 6233 was taxiing on taxiway F. Captain Li Zhiming looked around and saw that there were no other planes around. At this time, the taxiing route instructed by ground control was a long straight line, which was not stressful. Therefore, Captain Li Zhiming had some energy.

Tell Xu Xian something else.

"After takeoff, the company should contact us to verify the communication system. At that time, we can just say a few words by the way." Captain Li Zhiming said.

Xu Xian was surprised that he had not received this notice: "The dispatcher didn't tell me about this!"

"I told you." Captain Li Zhiming said: "If we are selected, we should be more formal and polite when speaking. It seems that there will be leaders visiting at the time. Don't be too casual."

The dispatcher did not name the specific leader, but it was quite rare to remind Li Zhiming so solemnly. Therefore, Li Zhiming felt it was necessary to communicate with the co-pilot in advance, so as to avoid the possibility of choosing them and Xu Xian not paying attention to what he said.

"What kind of leader? You have to communicate with the crew in advance. If you are so careful, you must be of a very high level." Xu Xian said with a smile: "I heard some captains say that it seems to be mainly to facilitate the contact between the crew and the company's operation control, and

Added automatic calling function.”

There are actually no barriers to communication between the crew and the control side. The usual VHF communication is with the control side. In the past, when satellite phones were not yet popular, when you encountered some special situations and wanted to contact the company headquarters, you still needed to go through

Control as a conveyance, this process is quite troublesome.

However, with the development of the times, it is quite common for aircraft to be equipped with satellite phones. The bureau has even issued regulations on the airworthiness of satellite phones. That is, when there is no satellite phone or the satellite phone cannot function normally,

Neither should be given a release.

Therefore, there is actually no big problem in communication between the crew and the company.

It's just that the crew contacts the control through VHF and the company through satellite phone or ACARS. There is no way to unite the three parties.

Normally, this problem is not obvious. Because there is no urgency or necessity, most of the time the crew has no need to communicate with the company.

But in an emergency, especially when the airline needs to provide technical support, this sense of fragmentation can be quite jarring.

Pilots need to switch back and forth between VHF and SAT transmitters. Frequent switching of transmitters will greatly increase the workload of the crew in emergencies. After all, in abnormal situations, sometimes the crew does not even have time to press the call button.

, not to mention switching the transmitter accurately.

Therefore, the technical department of Star Travel Airlines developed this emergency communication system. Its three-way calling and automatic calling functions can significantly reduce the communication pressure on the crew in emergencies. It is a pretty good design.

However, Xu Xian thought that if it really came to that kind of emergency situation, even if smooth communication among three parties and automatic speaking could be implemented, the crew might not even have room to talk.

Of course, Xu Xian is not denying the role of this system, but making it so formal makes him feel a little troublesome. Especially when leaders get involved in certain things, it will have a lot more formalism.

"There is an option to automatically send calls on the dialing page of the CDU satellite phone. We will test it when the time comes." Li Zhiming said: "You can take a look first to save yourself from not finding it later."

"Huh? Is it still the satellite phone option on the menu page?" Xu Xian glanced outside and saw that the F1 intersection was still some distance away from the plane. There were no planes around to intervene, so there would be no conflict. So, he

Prepare to follow Captain Li Zhiming's request to see how to operate the CDU.

You can choose to enter FMC, ACARS, ACMS and SAT systems on the menu page of CDU. Of course, the functions of different models and versions of CDU will have some differences. SAT is the satellite phone system.

However, when you want to make a satellite phone call, you cannot dial the number like a normal phone call. You need to add the international prefix, international code and area code, which will be very troublesome to remember. Therefore, the crew usually only dials the company numbers stored in it.

.

"Is it under the AOC option?" Xu Xian asked.

"Yeah! Click on it and take a look. It seems that the CDU has been updated, but I haven't seen it either." Li Zhiming glanced at the CDU screen on the passenger side: "It should be the AUTO option."

Originally, there was no automatic speaking function option. This was an additional function option added to the CDU after the technical department of Star Travel Airlines contacted Boeing for a small-scale modification. It is estimated that except for the technical department of Star Travel Airlines and Boeing, they came to participate in the modification.

Only the technicians knew about this new function, and basically all the pilots did not know about it. This time the emergency communication system was to be tested, so the dispatcher made it clear to the captain Li Zhiming about the new function.

"AUTO? Wait a moment." The AOC option records the contact numbers of the operation control centers of all aviation subsidiaries of the entire group, not just Star Travel Airlines.

The main aviation business of Wen Group is Chimelong Airlines, as well as Star Travel Airlines, Chimelong Business, and a cargo airline and a general aviation company. Each airline has its own operation control center, and each operation control center has more than

There was a contact information, which caused Xu Xian to turn two pages before seeing the AUTO option in the last option.

"When do you press this?" Xu Xian found the automatic speaking function option and asked Li Zhiming.

Li Zhiming: "The company seems to have to contact the control first, communicate with the control, and confirm that the channel will not be occupied before starting the test. At that time, someone will tell us how to operate.

If it is not an emergency and is just for testing, you must find a time when the channel is not busy. This will depend on the results of the communication between the company and the control side.

"Wait, okay." Xu Xian remembered the operation method clearly anyway, so he simply switched the page back to the flight segment page and prepared for takeoff.

"Xingyu 6233, contact tower 133.3." At this time, they were almost at the F1 crossing, and the ground control asked Xu Xian and the others to change the frequency.

"Tower 133.3, goodbye!"

"Tower, Xingyou 6233, in front of F1."

"Star Travel 6233, can enter runway 21 via F1, corrected sea pressure 1011." The tower control gave permission to enter the runway, and at the same time commanded the aircraft on the final line: "Kunlong 9478, minimum speed, release!"

"Okay, minimum speed, Kunlong 9478."

"Xingyu 6233 is fast!" the tower control also urged.

Xu Xian replied: "Okay!"

At the same time, Xu Xian turned on all the lights, turned on the terrain display on his side, and adjusted the transponder to the TA/RA position, giving the cabin a signal to take off immediately.

"The runway is safe, you can enter runway 21, and the takeoff thrust is 92.1." Before entering the runway, the crew must confirm that there are no other aircraft or vehicles, people, obstacles, etc. on the runway.

When the plane aligned with the runway, Xu Xian reported: "Xingyu 6233, get ready."

"Xingyu 6233, surface wind 040/01, runway 21, ready for takeoff." The takeoff permission was issued.

"Runway 21, ready for takeoff, Star Travel 6233."

Hearing the reminder of wind direction and speed, Li Zhiming muttered: "There's still a bit of a tailwind."

"Yeah, I guess we have to change runways soon." When Xu Xian started timing, he followed Li Zhiming's words and said: "The takeoff instructions are there, and the takeoff configuration is good."

At the last moment before takeoff, Xu Xian also confirmed whether the takeoff configuration was correct to avoid a takeoff configuration warning.

Li Zhiming: "No problem, let's go..."

...

Yunnan Tower Control Room.

The control tower of Dianyun Airport is located in the middle of the airport. Except for a small number of areas blocked by some terminal buildings, which are blind spots, most of the airport areas can be seen at a glance.

The tower controller who had just returned from his shift was drinking coffee to refresh himself and enjoying the final peace before the departure rush hour.

The colleague who got off work did not leave immediately. Instead, he stretched his muscles a little behind the control tower. After sitting for most of the night, he felt that his back was sore.

"What did you say about the training at the new airport?" My colleague relaxed his muscles and asked the tower control leisurely.

The tower controller glanced at the workbench and yawned: "Stop, the airport has stopped, how can we continue?"

"Oh, Dianyun is not a big city to begin with. We have to build a giant airport with three runways, and we are not afraid of choking ourselves to death." A colleague mocked, obviously very disapproving of Dianyun's behavior of building a second airport, at least for Dianyun.

Considerable doubts have been expressed about the size of the new airport.

"Isn't it just stuck in the throat now, unable to swallow or spit out?" The tower controller really believed it: "It is said that three runways will be built. The two parallel runways are both 4200 meters. We will use the 03/

The runway numbers are 21 and 04/22, plus a slightly shorter runway of 10/28, which seems to be 3400 meters. The airport land is more than double the current airport. I really didn’t know that our Dianyun is so rich.

.”

After nearly twenty years, the perennial winds on the Yunnan side have changed somewhat, so when designing the airport runway, an additional runway 10/28 with an angle of nearly 90 degrees was added.

A 3,400-meter runway is considered a good length in ordinary airports, but it can only be considered the smallest runway in Kunyang Airport, the new airport in Yunnan.

This alone reflects the wealth of Dianyun. However, the scale and expected throughput of the new airport Kunyang Airport seem to be too large to match the size of Dianyun City.

"Have you seen the design drawings of the new airport? Are the taxiing routes and procedures complicated?" a colleague asked.

This is not because of his enthusiasm for work, but purely out of curiosity. He applied for a temporary stay at the old airport and will not be transferred to the new airport in a short time.

"No! The taxiing route of the new airport is based on the old airport, so you will be familiar with it quickly. The procedures continue to be the same. The two airports are very close, and the direction of entry and departure has not changed significantly." Tower control said.

"That's good!" The colleague smiled and said: "You can just explore the way for me. If I decide to go to the new airport, you can give me some extra lessons."

"What's there to do?" the control tower said with a smile: "By the way, our airport really doesn't care about the fate of our airport control? The morning rush hour is getting earlier and earlier."

In the past, the morning rush hour at Dianyun Airport was around 7:30 in the morning, but later it was mentioned at 7:00, and now there is a tendency to continue to the earlier peak.

"All the good times have been taken up. If you want to increase flights, you can only move them as early as possible or as late as possible. Don't you think that not only the morning peak is getting earlier, but the evening peak is also getting later?"

I don’t earn as much as flying, but I still wake up early and work hard at night. Who can stand this?” a colleague complained.

"When we move to a new airport and there are more and more international flights, there will be many more early morning flights than now. It will be a headache then." Tower control complained.

Many international flights not only land at two or three o'clock, but also take off at two or three o'clock. When the new airport is moved, the number of international flights will definitely be expanded. By then, the control system will be really big.

"I'll let you worry about it first. I'm retiring at the old airport." My colleague laughed and said, "But do you think the new airport will be confused? How long has it been shut down?"

"I'll go, no way! I bought a house near the new airport. If the new airport is destroyed, then I will be in trouble." The tower controller almost cried.

The location of the new airport is in the wilderness. Without the blessing of the airport, the housing prices there would be almost free. However, with the announcement of the new airport, housing prices in many areas near the airport have increased a lot. The tower controller feels that the house

It will continue to rise in the future, plus it is convenient to work at the new airport, so even though the house price has more than doubled than before, I still bought a house with a loan.

However, if the new airport fails, then the house he bought will be ruined in his hands. Thinking of this, the control tower's heart froze.

"Probably not." The colleague originally made a joke, but he didn't expect it to hit his friend's nerves. He felt a little embarrassed and comforted him: "The site has been selected and construction has started, so let's put it down."

You’re out, how could you give up halfway? Don’t worry! Forget it, stop thinking about it, there’s a plane about to land, just keep an eye on it.”

"Then you mess with my mentality while I'm working?" the tower control complained.
