Pilot Driving Rules No. 1: All driving actions in the cockpit are under the control and guidance of the captain!
Article 5: The captain takes the lead in controlling and handling emergency situations!
Article 17: When the pilot and co-pilot have conflicting operations, they must unconditionally obey the captain’s judgment!
The second revised rule of the Pilot Driving Code: If there is a conflict between the pilot and co-pilot in the operation, the opinion of the pilot who has flown more hours on the same flight and the same type of aircraft in the past three years should prevail!
Bei Haiyang used this line and hit Captain Pang Lide's seven inches directly!
Most of the flying hours that made the old man proud were in the first half of his life. The second half of his life became intermittent due to teaching. Especially on this flight, the 939 model, his flying hours in the past three years totaled only a few hundred.
For several hours, most of them flew with Bei Haiyang.
Bei Haiyang is different. Since he was promoted to first officer, he has been fixed on this route and this model of aircraft; his more than 2,000 hours of flying experience are all on this!
That’s why I dared to confidently request to control the plane!
Pang Lide resisted the urge to punch, he couldn't imagine that the co-pilot, who was usually tired, had such courage to challenge!
Staring at him straightly, he finally choked out a sentence, "I reserve my opinion, but I recognize the ruling of the Second Amendment Rules!"
Bei Haiyang did not say thank you, the occasion was wrong, and the other party may not accept it, so let the facts speak for themselves!
"Beijing Enterprises Beijing Enterprises, this is Dragon Air 4607, requesting to enter approach control in advance! Requesting to lower the altitude to 18,000 feet in advance! Requiring clearance in front of the channel! Choose Donghai Airport as the emergency landing airport!"
Beijing Enterprises Center, "Are you sure you choose Donghai Airport? Shizhuang Airport is closer, and Tianjin Airport..."
Bei Haiyang, "It's too close! Our stabilizer is stuck and it's difficult to maneuver. We need a long enough distance to descend! Moreover, Donghai Airport has the longest runway!"
Beijing Control Center, "Understood! Dragonair 4607, descending altitude 18,000 feet, approach channel 124.3, clear ahead!"
After completely letting go, Bei Haiyang felt no pressure at all. His adrenaline levels were running high now. This was his plane, he was the captain, and he was in control!
The nose of the aircraft has been tilting downward due to the stuck stabilizer. What Bei Haiyang has to do is to use the tail elevator to balance this downward tilt, so that the tilt angle is within the normal range, instead of plunging headlong!
Normally, there is no need to exert such effort at all. He only needs to push the control stick lightly, and the plane will lower the height according to his wishes; but now he is pulling hard, which is completely opposite to the normal operation habit, and it must be reasonable.
Controlling the angle of descent is why Pang Lide was unwilling to make an emergency landing like this.
Because as long as one control is not good, the plane will be completely out of control, especially when the speed of the plane will drop to less than 200 miles before landing. No one knows what kind of impact the stabilizer will have at low altitude and low speed?
It’s really physical work! Fortunately, I have been exercising all this time.
Pang Lide began to prepare the descent checklist and implemented it one by one. This was originally Bei Haiyang's job, but now the captain's position has been changed!
"Donghai Tower, this is Dragon Air 4607. It is confirmed that it has landed abnormally. We need the longest runway and clear space in front!"
Donghai Tower, "Received, clear runway 02, and handle the critical situation!"
Bei Haiyang, "Dragon Airlines 4607 called the tower, I want to lower the altitude, please change the shape! Make sure the aircraft is within my control range!"
If the worst happens, they don't want to harm the ground!
Ordinary people may not understand the meaning of this sentence. In fact, they are afraid of crashing into a densely populated area!
The best way is to pass over the sea, but there is no sea route on this route, so they asked air traffic control to guide them to avoid the city!
Such a requirement means that they may fly a circuitous route rather than a straight line! This will add extra pressure to the pilot, but they must do it!
...Donghai Airport, police beeps!
Dozens of rescue vehicles swarmed out and headed for Runway 02, which had begun to be cleared. The runway is 4,500 meters long and is the longest of the five runways at Donghai Airport.
The most feared thing about an abnormal landing is a collision and fire, so most of these vehicles are firetrucks and ambulances, which stay in sections. The largest number of them are concentrated in the second half of the runway, which is where the plane may finally stop.
The braking distance of 939 after landing is within 1000 meters, which is related to many aspects, such as weather conditions, landing point, load capacity, etc.; the 4500-meter runway 02 can fully meet the landing of 939. The only problem is that flight 4607
Where will you land after aligning with the runway?
Under normal circumstances, after entering the landing procedure and correcting the ILS signal, experienced pilots will touch the ground about 300 meters from the top of the runway, and the front-to-back error will not exceed 1,200 meters. In this case, most of the runways will not be used.
But if, like the situation of Flight 4607, the aircraft cannot be accurately controlled to land a few hundred meters above the runway, and the stabilizer is stuck causing the nose of the aircraft to tilt down, the pilot cannot allow this to happen, otherwise he will
Not surrender, but shoot!
The pilot can only raise the nose of the plane! Landing with the nose of the plane raised may sound incredible, but this is the specific situation of 4607. What matters is the pilot's control ability, which is found in the downward tilt of the stabilizer and his own upward movement.
A suitable angle...
This process is very short. If you hesitate for a moment, you will overrun the runway and have to go around. Therefore, the landing speed of 4607 must be controlled slightly larger than the normal range to ensure a go-around after failure. This leads to a series of operational problems.
This is the danger that Pang Lide said!
It won't work if it drops too hard, it will be photographed; it won't work if it drops too softly. For an airplane, it only takes about ten seconds to reach more than 4,000 meters!
When the pilot cannot fully control the joystick and the stabilizer gets stuck during the descent, this is the key to the emergency landing.
In the tower, Air Traffic Control Director Xing Zhanbo frowned and his eyes were focused; Donghai Airport has maintained a safety record for a long time, and he did not want the record to be broken in his own hands, but this was not something he could decide.
Elder Zhou, who was on duty next to him, was also very nervous. "The stabilizer is stuck. Such a failure is rare for aircraft like the 939! Why don't they deal with it in the air? There is still time and enough fuel to circle a few more times."
It's always good to try a few times, so why rush and crash land in such a hurry?
Pressing the joystick forward is for landing. Pulling the joystick backward is the first time I have seen this..."
Xing Zhanbo shook his head, "Don't doubt the pilot's choice. There must be a reason for them to do what they do! They are more professional in operating the aircraft, and their control angle is different from ours!"
He paused and said in confusion: "That's very strange! Shouldn't Lao Pang be in charge of communication? How dare he completely let go of such a big thing and let the novices go down? This is not his character!"
