Blue Sky 9433, we have a problem with the instrument, now we have to keep climbing, we can't maintain altitude, we want to keep climbing, we should have to break through 3300. "The instructor reported their situation to the tower. If they were to maintain a 4-degree attitude and 75N1, it would be a typical climb and would not be able to maintain the required altitude at all.

If you are unable to implement the control directive, you must notify the ATC in advance, otherwise it will cause conflicts, and it will be a lot of things.

Now they are very close to 3,300 meters, and they will definitely cross 3,300 meters after a little more climbing.

"Blue sky 9433, you can continue to go up to the altitude 5400 and correct the sea pressure 1012." The tower gives the Blue Sky 9433 a higher height.

"Corrected sea pressure 5400, 1012." Instructor Chang replied, "Can you confirm your current speed and altitude from the radar?" ”

The speed and altitude of the target aircraft can also be seen on the radar screen, and the instructor wants to corroborate the instrument data in the cockpit to make sure that the correct data source is more accurate.

After a while, the controller said: "Now it shows two hundred and thirty knots of airspeed, and the altitude is just over three thousand!" ”

Teacher Chang compared the data and confirmed that there was only a problem with the data on his side.

"Blue Sky 9433, your failure doesn't affect normal flight, right?" The tower controller asked.

"No, I'm ......" Instructor Chang only said half of it, and Xu Qing's exclamation suddenly sounded in his ears, and at the same time, he felt that the head of the machine was planted down like a swoop!

Instructor Chang reflexively grabbed the steering stick, now he has just taken off, and the altitude has not even exceeded three thousand, what is the difference between rushing down and looking for death?

"Xu Qing, how did you kid fly!" Teacher Chang shouted.

The airspeed is unreliable, but there is a problem with the instrument display system, and there is no problem with the control system, and the steering stick on Xu Qing's side does not shake the lever, why can't he control the plane?

How dangerous is it to lose altitude after takeoff, Xu Qing doesn't know?

However, the nose of the machine leaned too violently, and Instructor Chang did not hold it at once.

"Master, it's not me!" Xu Qing argued while helping Teacher Chang with the pole.

He didn't shirk responsibility, but found that there seemed to be something wrong with the plane! It's not a problem with the instrument display, it's a problem with the control system! Otherwise, why would the plane bow its head without warning?

"If it's not you, can the plane bow its head on its own?" The teacher was annoyed.

Xu Qing: "It seems to be a trim, just now the plane itself was playing the trim forward!" ”

"That's right, instructor! Just now the plane has been trimming forward, I see! The one sitting in the observer's seat at the back said what he had just seen.

It's normal to play the trim, and he really didn't notice the abnormality of the trim wheel at first, until the trim wheel continued to play the trim forward, which was very abnormal.

Hearing this, Teacher Chang's eyes flashed, and he realized that things seemed to be a little not simple!

It was the trim wheel that had stopped just now, and it was when Xu Qing and Instructor Chang took the rod together, wanting to restore the plane to climb state, the trim wheel, which had been quiet for just five or six seconds, once again lost their minds, and quickly moved forward to trim, and the speed of their rod could not match the speed of the trim and bowed their heads.

At this moment, Teacher Chang finally knew what the concept of "all the time" forward trimming was!

He didn't move forward to level the match, Xu Qing wouldn't go forward to match as long as his brain was normal, so who did such a crazy move?

The most important thing is that they are obviously carrying the rod, but the trim can actually play forward, and the reverse operation cannot stop the trim process.

The so-called reverse operation instructions are that when the pilot pushes the rod, the trim cannot be played backwards, and similarly, when the pilot has the rod, the trim cannot be played forward.

The reason for this is that the steering stick cuts off the electric door!

When the lever is pulled backwards, the driving stick cuts off the electric gate will cut off the head trim command,

When the lever is pushed forward, the drivestick cut-off gate cuts off the heads-up trim command.

Since the stabilizer is the auxiliary mechanism of the elevator, under normal circumstances, the movement of the stabilizer must cooperate with the elevator, so the stabilizer and the elevator will not be allowed to move in the opposite direction, which is the role of the steering stick to cut off the electric door.

Reverse operation is only allowed when the stabilizer trim override gate is placed in the override position, and this design is mainly designed to facilitate the failure of limited control and jamming.

In the checklist for limited maneuvering and jamming, there is a step to put the stabiliser trim override gate in the override position.

But they didn't touch the stabilizer trim override gate at all, so why could the trim wheel operate in reverse? What is the reason why the trim can bypass the steering stick and cut off the electric door!

Reverse operation is a philosophy that has been used by Boeing for decades, and any pilot who flies Boeing has incorporated it into his flesh and blood, almost as if it were the truth. However, the change at this moment has ruthlessly shattered the cognition of the regular teacher.

At the moment when the teacher was distracted, another one was added to the warnings!

“Terrain，Terrain，PULLUP，PULLUP！”

Terrain warning triggered!

Xu Qing and Teacher Chang's hairs all over their bodies stood up, a spirit, cold sweat began to seep out, their eyes moved out, and beads of sweat the size of beans slipped down their foreheads!

Today is indeed a good day, the sky is clear and there is no obstacle as far as the eye can see! Right in front of the two of them, a behemoth came to them!

That's a mountain!

......

Above the sky, there was already a thousand jun, and on the runway where Xu Qing took off just now, a plane from Lotto slowly came in.

The captain of Lotto yawned, steered the plane into the runway, rubbed his eyes, he didn't sleep well last night, and now his spirit is still a little sluggish.

The captain of the Lotto aligned the runway and looked down into the cockpit, he wanted to see if the plane's heading coincided with the direction of the runway, so as to determine whether the plane was really aligned with the runway.

Suddenly, the captain's eyes, which were still a little worried, widened suddenly, his brows furrowed, he pointed to a diamond-shaped pattern on the navigation display, and turned to the co-pilot next to him: "Is this plane descending?" I read that right! ”

The co-pilot followed the captain's point, and then looked at the display on his side: "Yes!" This plane is descending, but, looking at this position, isn't it the track of 234? It must have just left the port! Can you drop altitude just after takeoff? ”

"Could it be that there is a wind shear?" The co-pilot guessed.

It is very easy to lose altitude when encountering wind shear, otherwise it is really difficult to explain the situation of taking off and losing altitude.

"It shouldn't be possible! You see the windbags are wilted, there is almost no wind, the weather is so good today, where does the wind shear come from when the wind is calm! The captain bared his teeth: "Something's wrong, it's definitely wrong!" ”

"Tower, Lotto 7189......"
