Descent from an altitude of 10,000 meters [MTL] (Completed)

Chapter 27 Wind Shear

Chen Jiayu didn't expect that his opportunity would come so quickly.

When he flew back to Beijing from Shanghai, the flight originally planned to depart at 2 pm had been delayed to 8 pm, but his waiting at the airport was not counted as duty time, so he could still fly at night. When checking in before takeoff, he saw the weather forecast that there was a severe thunderstorm in Beijing, and he sighed inwardly - if it hadn't been for the fuel tank problem, he might have been sitting at home now if he had set off a few hours earlier. He could only hope that the weather would be better when he arrived in Beijing.

However, the opposite happened. After he entered the Beijing area, his heart sank again when he saw the weather. Thunderstorms, coupled with gusty winds, can be said to be the last situation any pilot wants to encounter. He glanced at the fuel gauge and saw that there was still about an hour and a half, which was not bad. He could try to land a few times. If it didn't work, he could make a backup landing in Tianjin or even Shenyang.

The sound in the channel was a bit noisy, and he heard dense instructions at the frequency when he entered the approach control area. Chen Jiayu was stunned for a moment. The control voice was very low, but the tone and tone sounded too familiar...

"Air China 1328, approaching Beijing, radar saw it. Blind landing on the right side of runway 17, maintain an altitude of 4,000 meters first." When he called himself, he realized that it was Fang Hao on the other side of the microphone, but his voice was too hoarse. It was so embarrassing that Chen Jiayu almost didn't recognize him.

He looked at the radar and said: "Keep 400, Air China 1328. Apply for heading... 350."

Fang Hao paused and asked him: "Air China 1328, are you planning to fly to the final direction? Now we are changing the direction of the runway. The aircraft approaching south around runway 17 are all pulled up because of the ground wind problem." When Chen Jiayu heard this, his heart was moved - wind shear refers to an instantaneous change in wind direction, which is the most dangerous condition for aircraft taking off and landing. Fortunately, the weather radars of modern civil aviation airliners are equipped with windshear warning, so if windshear is detected ahead during the approach, the pilot will choose to go around. But in this thunderstorm, coupled with wind shear, five or six planes went around at the same time, and the runway changed direction, the control may have been so busy that it was smoking.

Chen Jiayu answered briefly: "We are preparing for the five sides. Apply for heading 350, Air China 1328."

Fang Hao agreed: "Air China 1328, heading 350 agreed. Also, check the fuel level. I will guide you in the terminal area to delay for half an hour. Is there any problem?"

Chen Jiayu also knew the weather conditions, so he said: "It seems to be no problem at the moment." He did not mention the fuel level for an hour and a half. After all, he also wanted to leave early. Passengers would be unable to sit still after a five-hour delay. This is human nature. .

Fang Hao turned on the microphone, but seemed to hear him cough. It stopped for a second, and then turned it on again: "Air China 1328, received. Our radar...sees that the weather may pass in half an hour."

"Yeah, no problem." Chen Jiayu was very talkative this time.

After a while, Fang Hao asked on the channel: "Air China 1328... Please help me check the weather here, 20 nautical miles from your position between 10 and 11 o'clock." Flights in the sky rely on the tower's reports to understand the ground weather. Similarly, control at the tower sometimes needs to rely on weather instructions from aircraft in the sky to make decisions. Fang Hao could not fail to recognize him, but he was very polite and used the honorific title. But Chen Jiayu had to concentrate on monitoring the situation of the plane. Accidents were most likely to happen when the weather was bad, so he couldn't distract himself from thinking about it.
