"Okay, Comrade Captain, I made a note of it, you continue." When Zhou Hai heard the words of the captain of China Southern Airlines, his spirits perked up, and he quickly wrote down the basic performance parameters, and in his mind, he had a basic understanding and concept of the behemoth under him.

The metal giant bird under him embodies countless cutting-edge aviation technologies and the crystallization of the wisdom of geniuses.

"The cockpit uses a flat liquid crystal display system, a total of 5 LCD displays, which display fuel data, inertial guidance and GPS positioning guidance data, altitude, airspeed, horizon, equipped with a wire-by-wire flight control system, that is, fly-by-wire control, while leaving a hydraulic control system as a backup."

The captain of China Southern Airlines knew that the situation was urgent and did not delay, and immediately explained the detailed data and information about the cockpit: "The landing gear switch is located directly in front of you, next to it there is the cabin management system, the electronic power assist system is located in the middle, the brake is in the left hand, the flaperon system is controlled by the flight computer, the electronic engine management system and the automatic flight indication system are located on the right side of the two LCD displays, which contain the flight information management system. ”

In the cockpit with the wind howling, Zhou Hai listened quietly, absorbed the detailed data and information about the Boeing 777-200 model explained by the captain of China Southern Airlines, and gradually mastered this metal giant bird weighing more than 200 tons.

Zhou Hai had long known about fly-by-wire control systems, and he had memorized the principles and infrastructure, but this was the first time he had really come into contact with fly-by-wire systems, not from books.

Zhou Hai did not take it lightly, but was much more cautious.

Because, there were hundreds of passengers on the entire plane, including himself.

The captain of China Southern Airlines continued: "If the fly-by-wire control fails, all flight control surfaces can be hydraulically driven, the flight computer control screen is located in the middle, the 777-200 has two generators, a generator of an auxiliary power unit and an auxiliary power system, and the two engines are Pratt & Whitney P4000, even if one of them fails......"

"Drop!"

At this moment, a sharp and rapid prompt sounded, interrupting the communication between the two, the electronic engine management system flashed a dazzling red light, and the second LCD screen on the left side of the front came out with a warning that the right engine had a fire accident.

The fire was detected by the flight computer at the first time, and the fire extinguishing device successfully extinguished the fire, but the right engine had stopped and was no longer running.

Due to the fire and shutdown of the right engine, the power output was terminated, resulting in the power of the whole aircraft being reduced by half, and the fuselage was immediately unbalanced, and the center of gravity shifted to the right side, which in turn affected the smooth flight attitude.

The change in flight attitude affects the flaperon system due to the influence of air flow and the shift of the center of gravity, which in turn affects the flaperon system, making the autopilot ineffective.

Signal sensors and feedback sensors throughout the cabin then collect data and transmit it to the central processing unit of the flight computer.

"Drop!" The autopilot flight system sounded again, and the central screen was emitted with a message indicating that the autopilot had failed.

The engine on the right side failed, the autopilot failed, and the whole process happened almost instantaneously, making it difficult to react.

“……”

Seeing this, Zhou Hai fell silent, and after a short period of stunned, the whole person did not dare to delay, and quickly held the control plate and cut into the manual operation state.

Press the control button of the right engine to manually shut off and cut off the oil supply, while pushing up the throttle valve to increase the oil supply to the left engine and pulling the lever to the left.

Streams of high-quality aviation fuel flow to the combustion chamber along the fuel supply channel like a torrent, and the Pratt & Whitney P4000 high-bypass ratio aviation turbofan engine on the left wing enters a full-load working state, and the turbine intake air temperature rises to 1,300 degrees Celsius, bursting out of surging and terrifying power.

Under the full load of the left engine, the fuselage is tilted to the right laterally, with an inclination of about 4 degrees, and can only stop tilting, and does not return to horizontal flight, and the flight altitude gradually decreases at a speed of three meters per second.

A single P4000 turbofan engine can burst out a high thrust of 25 tons when running at full power, but even so, it will not help.

Suddenly, more than 300 passengers on the entire flight fell into a panic again, and the screams were incessant, resounding throughout the cabin.

In the radio communication channel, the tower controller, who had already heard the sound of a rapid siren, shouted anxiously: "Flight CZ8954, what happened?!" ”

"The engine on the right side caught fire and failed, it was extinguished by a fire extinguisher, and the autopilot failed, so I switched to manual driving."

Zhou Haiyu frowned, held the control panel in his right hand, observed the airborne avionics system with both eyes, and reported to the tower of Shicheng Airport: "The right side of the fuselage is tilted 4 degrees, with a descending altitude of 3 meters per second, our plane is likely to be unable to reach Shicheng Airport, if the situation deteriorates further, our plane will start a forced landing nearby, please give the permission to make a forced landing immediately." ”

“……”

Hearing Zhou Hai's words, the captain of China Southern Airlines, who had not finished speaking, opened his mouth as if he had been struck by lightning, and fell silent.

The same is true of the airport tower, where there is no sound.

The whole flight was already in trouble, and now there is a problem with the right side of the engine.

Despair!

A sense of despair shrouded the hearts of everyone in the Shicheng Airport Tower, giving birth to a feeling of powerlessness.

Forced landing, the meaning behind this aviation term, is second only to plane crashes and deaths.

Whether it is life or death is completely predestined by heaven.

And, where will the forced landing be located?

The route from Harbin to Shicheng is a continuous urban agglomeration with a densely populated area with a population density of up to 200 people per square kilometer.

The whole route, there is almost no place for Boeing 777 to make a forced landing, the distance between Shicheng Airport and the flight is more than 200 kilometers, the capital airport can not let you make a forced landing, Tiancheng International Airport is even more so, the only airport that can meet the Boeing 777 landing standards and the nearest airport is only Shicheng Airport.

"Flight CZ8954, the highest operational command center in the Central Theater here, allows your plane to make a forced landing in an emergency." At this moment, a slightly low but powerful middle-aged male voice entered the special communication channel on board, as if it was the truth, and gave Zhou Hai the permission and permission to make an emergency landing.

Zhou Hai held the control panel tightly, trying to stabilize the flight state of the fuselage, and when he heard this, he breathed a sigh of relief in his heart, and immediately responded: "Yes, I received it, and I am trying to fly to Shicheng Airport." ”

"Call flight CZ8954, three of our planes are ordered to escort you throughout the journey." Immediately afterwards, another voice sounded on the radio: "Brother, you are good, come on, you haven't lost the face of our Air Force." ”

"I received it, thank you very much."

"Buzz!"

In the blue sky, three silver-gray Bayi painted J-10 fighters cut through the sky like eagles, waiting for about three kilometers away from the flight, out of the supersonic flight state, low altitude and keep a safe distance from the whole flight, two on the left and one on the right, maintain order, and escort the flight.
