The channel was intercepted, and Xu Qing then pre-positioned the APP, that is, the glide track.

"Blue Sky 9564, 23L fairway!" Instructor Chang reported.

"Blue Sky 9564, continue approaching, maintain speed of 180 to 10 nautical miles on five sides!"

"Keep approaching, 180 to 10 nautical miles!"

It didn't take long for Xu Qing to see that the glide path began to automatic, and according to the SOP, he was ready to slow down and release the wheel.

As soon as the left hand put on the speed adjustment knob, the right hand of the regular instructor on the left was also raised at the same time.

"How...... What's wrong? Xu Qing found that the direction of Instructor Chang's right hand was also a speed knob.

Instructor Chang rolled his eyes and pressed down Xu Qing's left hand: "Uncle, you slow down now, what about the people behind?" Didn't they all keep you at 180 to ten knots, that sounded right? ”

"But doesn't SOP say that the glide path will be released when it moves?" Xu Qingshun replied.

"SOP told you to jump now, will you jump?" Instructor Chang had a stiff neck: "You put the wheels now, the flaps are 15, the speed has been reduced, the spacing is smaller, and the plane behind you has to slow down?" The airport is not opened by your family, so you have to take care of yourself? ”

"Let's establish a landing form before 1000 feet, a stable approach, and the height is enough, what's the hurry?"

Xu Qing didn't think of this layer, and when the simulator was modified, there was also a requirement to maintain the speed to a certain distance, so it was natural to think that it should be no problem to maintain the speed of 170 after the flap 15.

Although Teacher Chang brought up the matter seriously, he didn't pay much attention to it at the time. How much impact can the speed difference of more than 10 knots have? He didn't believe it, he slowed down, and the plane behind him couldn't fly.

Many things, you say 10,000 times, you may not have experienced them once, and they are unforgettable.

The so-called wonder of fate is wonderful. In the future, Xu Qing became a pair of people, and the first go-around after starting to sit normally was caused by the premature deceleration of the front plane and the slow disengagement action.

Of course, that's more than a year later, and I'll talk about that later.

After that, Xu Qing waited until the FAF, that is, the final approach positioning point, to release the wheel, flap 15. The glide path is also intercepted at this point, and the go-around altitude is adjusted after the glide path is intercepted, and the APP mode light is turned off at the same time.

The significance of the APP mode light off is that the pilot cannot exit the blind landing mode by pressing the APP mode button.

Here is an explanation that once the APP mode is pressed, after the blind landing is established, it is impossible to exit the blind landing mode by choosing other methods.

For example, after establishing a blind landing, for some reason you don't want to continue to descend.

In this case, the ALT HOLD method will not take effect.

Pressing V/S, LVL CHG, VNAV also does not interrupt the blind landing mode.

There are three ways to interrupt blind landing mode!

First, disconnect the autopilot and fly manually. This should be understood in the best of the three ways. There is one caveat here, though.

It's a good idea to turn off the guidance while disconnecting the autopilot.

Because disconnecting the autopilot restores the control of the aircraft, the guidance is naturally in blind landing mode, which will guide the pilot to continue to fly according to the glide path.

Some pilots are accustomed to being guided by it, and even if they quit automatic driving, they may habitually follow the guidance, and there is no difference between continuous automatic driving.

The second is to press the TO/GA, and the autopilot will switch to go-around mode.

The third is to switch the frequency, that is, to switch the blind drop frequency.

Therefore, some pilots are accustomed to adjusting the backup frequency of blind landing to 108.00, and no airport will use this frequency as the blind landing frequency.

When the pilot wants to abort the blind landing, he can quickly abort by switching to the standby frequency 108, which is quite convenient.

After the flap 30 units are green, the landing pattern is completed, and the landing checklist.

The starting valve is in continuous position, the speed brake is pre-positioned with a green light, the landing gear is lowered with three green lights, and the flap 30 is in place with a green light.

After intercepting the blind landing, the frequency is changed from the approach to the tower, which is the last frequency of the approach phase of the aircraft.

"Tower, blue sky 9564, 23L blind landing."

"Blue sky 9564, ground wind 230/02, runway 23L can land!"

"Runway 23L, you can land, blue sky 9564!"

"The landing command is there, the wind of 230, there is no crosswind, or you control the landing." Or as I said before, if I shout to take over the manipulation, you will immediately hand over the manipulation, you know? Instructor Chang instructed Xu Qing to disconnect the autopilot.

Xu Qing's heart was up and down, he thought that it would be good for Instructor Chang to let him manipulate until he was about to land, but he didn't expect Instructor Chang to let him manipulate the landing.

At this time, Xu Qing was a little bottomless.

It's a real flight, not a simulator that can be restarted at any time.

If you make a heavy landing, won't you get yourself in trouble?

Instructor Chang saw that Xu Qing had not disconnected the real autopilot for a long time, and saw through this kid's weakness at a glance: "You kid is grinding and chirping, where is the stunned energy when modifying?" Don't worry, I'll give you a cover, it's okay! ”

Teacher Chang has said everything about this, where can Xu Qing refuse, hehe smiled: "Teacher, help me take a look at it, I'm afraid my hands are shaking." ”

"Don't worry, if you shake the sky, I can press it down for you." Instructor Chang was really impatient, and the height was now 1,200 feet away from the airport elevation, and he flew a hammer when he was consuming.

"It's broken!" Instructor Chang was too lazy to wait for Xu Qing to break it, so he held the steering wheel with both hands and disconnected the automatic driving himself. Holding the steering wheel with both hands, this is to prevent abrupt deflection after the automatic driving is disconnected.

After confirming that there was no abnormality and that Xu Qing also kept the plane under control, Instructor Chang gradually let go of the control and let Xu Qing control it himself.

On the five sides, there is almost only a headwind, no crosswind, and no turbulence, which is an excellent opportunity for Xu Qing to practice.

"1000 feet, steady approach!"

Instructor Chang turned on all the lights and checked the landing form again, and after everything was normal, he could concentrate on Xu Qing's manipulation.

Under such meteorological conditions, the difficulty of maneuvering on the five sides is very small, and Xu Qing only used a small amount of maneuvering to maintain the stability of the aircraft.

The key is to decide below the altitude, and the low-altitude treatment is the difficulty.

"500 feet!"

"100 to decide!"

Xu Qing's hand holding the steering wheel couldn't help but tighten, and even oozed a little sweat.

"Decisive, the runway is ahead."

"Straight ahead, not right front, why are you going to the right, don't deviate, if you deviate any more, you will fall on the grass." Teacher Chang's letting go is surprisingly large, even if Xu Qing deviates, he just reminded him, he didn't get started, he wanted Xu Qing to understand and correct it himself!

Xu Qing couldn't see it, he knew that too rough correction in this low-altitude situation might trigger the warning, so he was restrained, which led to more and more deviations.
