Chapter 135: Worry

After all, like aircraft navigation, its navigation, communication, and identification system is mainly to ensure flight safety, and to ensure voice and data communication between the sky, air-to-air, air-to-ground, ground-to-air, and air-to-sea, and it can independently complete radio navigation, landing, and air formation.

In fact, there is a unified framework for communication, navigation, and identification systems:

HF (High Frequency Communication), VHF (Very High Frequency Communication) and ACARS, etc., let's understand together, the air-to-ground transmission of aircraft is mainly divided into two parts: radio communication and data transmission, and radio communication is mainly divided into high-frequency communication and VHF communication.

HIGH-FREQUENCY COMMUNICATION (HF HIGH FREQUENCY COMMUNICATION), high-frequency communication can provide a long range of communication, including communication between aircraft and aircraft, and communication between aircraft and the ground. The system, which has a frequency range of between 2 MHz and 29.999 MHz (data taken from the Boeing 737 aircraft), uses signal reflection from the Earth's surface and the ionosphere to communicate. The distance of communication can vary depending on altitude, frequency, and time of day.

VHF VERY HIGH FREQUENCY COMMUNICATION, VHF COMMUNICATION PROVIDES A COMMUNICATION WITHIN VISUAL DISTANCE. VHF communications can provide voice and data communications between the crew and the ground and other aircraft. The radio band of the system is 118 MHz to 136.99 MHz. (Data taken from Boeing 737 aircraft)

THE SEL CAL SELECTIVE CALLING SYSTEM IS BASED ON THE AIRLINE'S WIRELESS NETWORK AND IS CONNECTED TO THE HIGH-FREQUENCY AND VHF SYSTEMS ON THE AIRCRAFT TO PROVIDE GROUND-TO-AIRCRAFT COMMUNICATION. Each aircraft has a different four-character code, each letter represents a single audio, and the base station calls each aircraft through a different tone. When the aircraft receives this code, the cockpit light display informs the crew.

The data transmission part is divided into aircraft communication addressing and reporting system and satellite communication, and the satellite communication system is based on the ground and satellite for the air-to-ground transmission of data and voice. Satellite communications can transmit higher quality data and voice recordings than high-frequency and VHF communication systems. It can offer three communication channels: Aero-H Classic, SwiftBroadband (SBB), and ACARS.

ACARS AIR COMMUNICATION ADDRESSING AND REPORTING SYSTEM, WHICH IS A DATALINK COMMUNICATION SYSTEM FOR MANAGING FLIGHT DATA AND MAINTENANCE DATA. It allows the crew to transmit data and information to the ground on demand or at regular intervals. The data that can be transferred includes crew identity, take-off and landing information, engine performance, flight status, and maintenance information.

Of course, in Fu Qiutong's mind at this time, these technical problems are actually a trivial matter, she only needs to arrive at the meeting place with the governor Feng Jitong before the floating car crashes, only then can Du Jin really live, and some problems in the colonial military government that may cause war turmoil can also be solved, so at this time she has only one requirement for the navigation system, that is, not controlled by others, stable and fast to arrive at the assembly point, As for all the other external factors, Fu Qiutong is not to consider, after all, she is a manager, not an employee.................................................................................

"How's it going? His condition suddenly deteriorated? ”

When he came to the makeshift medical room, Fu Qiutong immediately asked the leader of the trauma team, eager to know the risks that Du Jin might face at this time, and the team leader looked at Du Jin, who was injected with a tranquilizer and slowly relieved his emotions, and did not hesitate to answer immediately:

"Minister Fu, Mr. Du is because of a certain memory of the previous period after waking up, or some people's mood fluctuations, the situation just now, his body surface damage has been healed, those inexplicable bone contusions are caused by strong external force squeezing, we can only do simple docking, but the real danger is the situation of his internal organs, if we do not use the Class I treatment repair cabin for treatment, then we can really buy Mr. Du very little time."

Hearing the second half of her subordinates' words, Fu Qiutong instinctively worried in her heart, the data transmitted by the probe she left in the temporary barracks was not only widely transmitted to the office area where the governor was located, but also a backup data was transmitted back to the information receiving terminal of the floating car, although the timeliness would be worse, but she knew very well that although the people in the photo were equipped with the equipment of the Ganymede ground emergency support force, these people were definitely not soldiers who came to support, but wild wolves who got up to "ask for their lives", The blinding method left by Fu Qiutong at that time was very effective in blocking the pursuit of the unknown forces, but it also made Fu Qiutong worried:

"I'm afraid these people are heading towards Du Jin, and the parasite that was stripped from the face of the previous Unity Sect killer and contained, I'm afraid we have no room for negotiation with that group of people before, if we are found then................ Forget it, now is not the time to worry about this. ”

Fu Qiutong just hesitated and hesitated for a moment, then forcibly suppressed the worry in her heart, she nodded to the leader of the trauma team, and then slowed down to Du Jin's side, Du Jin's consciousness had almost recovered at this time, but his ability to control his body did not have a corresponding recovery, of course, this is also a matter of course, if it were not for the help of drugs and instruments, the injuries on his body would not allow him to wake up at all, let alone hope to regain control of his body, so even if Du Jin couldn't turn his neck, But he still saw Fu Qiutong's face from the corner of his eye.

"I'm in the Blood Seal World right now? This should be the official of the colonial government I saved before, uh, I don't know if the upgraded handheld terminal she wanted to give me before was lost, after such a long delay, "Xiao Ai" will definitely be very lonely by then....................."

Du Jin knew that he had re-crossed into the world of blood seals the moment he saw Fu Qiutong, after all, this female official had a very modest attitude towards herself, which made Du Jin have a preconceived impression of her:

"It's okay, as long as I can travel back, with the medical technology here, I should have no problem saving this life, and the time difference between the two worlds can also give me some ways to think about how to face the infection in this world next, according to the situation when I came back from the "Blood Moon Dimension", the unknown flesh and blood membrane covering my body may have a great connection with me, and it may even be directly integrated into my body, I don't know what benefits this change will bring me, If the size of the items I can carry is increased, I can also get some weapons, which can at least provide a little help to protect Si Qing and my parents. ”

Looking at Du Jin's eyes that were clear for a moment and then thoughtful, Fu Qiutong was just happy in her heart, but she could intuitively feel that Du Jin knew herself at this moment, which provided a great help for him to calm his emotions, after all, no one would really relax in front of strangers, and it would be much better to be an acquaintance at this time.

"Comrade Du Jin, don't worry, now that you are safe, the killer has been controlled by us, now I will take you to a safe place, you don't have to be nervous or worry about anything, the most important thing now is to let Comrade Du Jin your emotions and mentality, we can prepare the next step of treatment for you, okay?"

Du Jin didn't refuse, of course, he didn't have any reason to be anxious, after all, his life was still hanging in the sickle of death and the pen of Hades at the moment, he didn't want to get anything from this, the only thing he wanted to do was to quietly leave and return to the world when the god of death and Hades quarreled about the ownership of his posthumous life.................................. So Du Jin took the initiative to blink his eyes very cooperatively, and seeing Du Jin's quick and positive reaction, Fu Qiutong also showed a smile on his face.

Her concern about Du Jin's life and death, in addition to Du Jin's possible value to the entire military government, on the other hand, is her gratitude to Du Jin for saving herself and her guards, she has always been a person who knows how to repay her kindness, as for other emotions, Fu Qiutong did not have them at this time, After all, Du Jin is not a male god who descended from the sky to make the female creatures around him have a positive value of 1008.6 to increase his favor, and Fu Qiutong has his own family and family, and his loyalty to love is second only to his responsibility for his work, and the medical team on the side is also relieved to see that his chief and the patient have a friendly and harmonious exchange.

After a short silence, Du Jin thought of Li Mengyan's comfort, with his visit before being attacked, Li Mengyan's place of residence was not too far from him, although judging from the results, Li Mengyan may have been summoned by Governor Feng Jitong, or had other arrangements to leave the residence in advance, but he couldn't judge whether the killer's ability could leave any lasting impact, what unnecessary impact it would have on Li Mengyan, and at worst, if the killer used his ability to start a large-scale spiritual erosion nearby, Li Mengyan just went home, although this possibility is very small, but Du Jin also has to consider the risk of its appearance.

In the present world, the people Du Jin cares about, the first thing is his parents and Si Qing, as his comrade-in-arms and friend in the blood seal world, Li Mengyan may be compared with these people, the status in Du Jin's heart is a little different, but just pay attention to the blood seal world, Li Mengyan is definitely the person Du Jin is most worried about at this time, at least until Du Jin's body is not completely cured and can return to the present world, this worry has always appeared in Du Jin's mind, and it cannot be dispersed, of course, "Xiao Ai" who has exceeded the scope of human safety It is not included in Du Jin's concern for his safety.
