Chapter 42: The go-around

"That's right, isn't that kid Chen Yi yelling to implement it every day now?" Teacher Chang said, "You do it first." ”

After FAF, Diao Jie first pushed a decline rate of 850.

When it was close to 9 nautical miles, Xu Qing reported in advance.

"9 nautical miles, 4530!" Xu Qing, as PM, helped Diao Jie report the height. This 4530 is the standard altitude of 9 nautical miles, not the immediate altitude.

When it reaches 9 nautical miles, the altitude is 4610.

"4610, 80 feet tall!"

Diao Jie increased the decline rate to 1000, and the regular instructor immediately started and reduced it to 900.

"You didn't push the descent rate 0.2 nautical miles ahead just now, so it's a little bit high, and you don't need that big descent."

Sure enough, at 8 nautical miles, it was only 30 feet tall.

"Just hold it for a while and rub it back!"

Diao Jie followed the instructor's advice, maintained a decline rate of 900, and when it was close to 7 nautical miles, he switched back to 850, and when he reached 7 nautical miles, it was only 10 feet behind, which was basically on the standard.

The 6 nautical mile altitude is still in good agreement with the standard altitude indicated in the approach map. At 5.5 nautical miles, Diao Jie confirmed that the height limit could be met, and directly adjusted the height on the MCP board to 2300.

Maintain a baseline descent rate of more than 800 and fine-tune up and down to ensure that the descent profile of the aircraft is in perfect agreement with the profile given in the approach map.

When the altitude drops to 3000, Diao Jie adjusts the go-around altitude, and the go-around altitude can be adjusted before the 300-foot DDA.

The weather conditions given by Teacher Chang are very good for Xu Qing, and there are no critical weather conditions. Before the DDA, the runway was clearly visible.

"Runway visibility, left front!"

The channel of the VOR has an angle of 2 degrees to the runway, which is not very positive. This results in a visual view when the runway is not directly ahead.

This is not particularly uncommon, and even some blind landing courses will be biased.

"Let's do it." Teacher Chang reminded.

Teacher Chang has already said before, and the two of them are not surprised.

The two exchanged manipulation communications, and Xu Qing took over the manipulation and shouted: "Reset the guide!" ”

This reference point for the VOR approach is not the head of the runway, and the guidance cannot be followed, so the guidance should be reset and the guidance removed.

"Reset the guide...... Diao Jie snorted, and suddenly, without warning, turned to the regular teacher, and said: "Teacher, I don't know how to reset the guide!" ”

Xu Qing held back a smile on the side, and he didn't know how to reset the guide.

Only shouting, not doing! It's a shame that Teacher Chang finally let him be replaced, otherwise it would be Xu Qing who would be embarrassed.

Teacher Chang's face turned dark, and he said angrily: "Will you restart the computer?" ”

"Yes!" Diao Jie replied dumbfoundedly.

"Do you want to close it and then open it?"

Diao Jie's face was crowded, and he said incredulously: "Is it also closed first and then opened?" ”

"You try to sprinkle!"

As soon as Instructor Chang's words fell, Diao Jie quickly turned the guide off and then on, and the strange thing was that even if he opened it again later, the guide did not appear.

"Learned?" Teacher Chang smiled and patted Diao Jie's shoulder.

Diao Jie nodded happily, seeing that the atmosphere was so harmonious, Xu Qing was naturally a little relaxed.

When he was more than 100 feet above the runway, Xu Qing put almost all of his energy on the ground. At that moment, the simulator's set disappeared and became a white expanse.

Xu Qing's mind was stunned for a short time, and when he reacted to the need to return to flight, even if he pressed TO/GA on the accelerator, it would take time for the thrust to be added again. The plane sat down uncontrollably, and the landing gear slammed into the runway.

As the thrust gradually increased, and at the same time, Xu Qing's lever action made the plane that had been touched by the ground rise off the ground again.

The moment he left the ground, Diao Jie blurted out: "It's rising!" ”

When this sentence came out, the simulator's set froze again.

This was followed by a strong questioning voice from the teacher: "What did you say? ”

Teacher Chang, who was still pleasant just now, became murderous in the blink of an eye, and Diao Jie was stunned by this sudden change. Not to mention Diao Jie, Xu Qing is no better, he hasn't come out of the go-around action just now.

Taking advantage of this time, he carefully recalled the go-around action. The more I thought about it, the more I felt that what I was doing stinks.

Not to mention the slow reaction, I was stunned for more than a second, and if the action was fast enough, it was very likely that the plane would not have to be grounded.

In addition, the large thrust of the go-around makes the nose of the aircraft rise suddenly, and the attitude of the aircraft exceeds 20 degrees in a very short time, which is almost a complicated state. Fortunately, the back was suppressed, otherwise the nose of the plane would "fly" upwards again, and the speed would go down smoothly, so as not to make a stall, it would be even more embarrassing.

Xu Qing's mind was still thinking about his ugly go-around operation before, how could he have any extra IQ and think about what was wrong with the phrase "rising".

Diao Jie's scalp was numb from the aggressive questioning of the instructor, and he didn't understand what was wrong.

"That's it!" Instructor Chang's arm stretched out and stepped back: "The warning is out." ”

Just before Xu Qing and the others understood what Instructor Chang meant, the simulator was thawed, and Xu Qing hurriedly stabilized the plane.

When his gaze swept to the airspeedometer, his body tensed.

Because after Xu Qing stabilized the attitude of the plane, the airspeed began to rise rapidly, and when he noticed, the airspeed had reached 180 knots, and the limit speed of flap thirty was 175 knots!

Overdrive!

Xu Qing finally knew what Instructor Chang was annoyed about, after the go-around, he should first transfer the flaps from flap thirty to flap fifteen.

Diao Jie also discovered this problem, and in a panic received the flap fifteen, and a fine cold sweat slowly oozed from his head.

"The go-around configuration is wrong, the flaps are overspeeding, how long do you say it will stop?" Instructor Chang's voice came slowly: "The go-around is the last resort to ensure safety. However, when a short period of time from a small thrust to a large thrust and a large change in the attitude of the aircraft at the same time, it is necessary to react quickly and accurately. As soon as the thrust comes up, the airspeed will go up, and if you react a little slower, you will be overspeeding. I don't blame you for putting away the landing gear first, but only today, after all, our company has only been out once recently. However, you have to remember that the go-around of the simulator and the real flight are not in the same state of mind, and your simulator go-around is all messed up like this, and if you really want to go back on the flight, wouldn't that be a warning one after another? ”

Instructor Chang's excited words kept coming in Xu Qing's ears, and suddenly, Xu Qing's chair back was slapped hard by Instructor Chang, which frightened Xu Qing for a moment.

"Why didn't you stabilize the attitude of the plane when you returned to flight, don't you know that just two days ago, the company had a go-around boom incident, what happened to the captain and co-pilot of that flight, I don't know?"
