Chapter 54 There is something wrong with this plane
Blue Sky Air Base Building Quality Center.
Teacher Wang Qiang, who had been looking for the quality center supervisor Wu Yong yesterday but to no avail, came again today. This time, his luck was not so bad, Wu Yong was in the office. Moreover, when Wang Qiang asked for the QAR historical data of machine number 1566, Wu Yong did not refuse. After all, this kind of data was not something that needed to be kept secret.
However, after Wang Qiang saw the QAR data of flight 1566, he had a fierce argument with Wu Yong.
"This aircraft started to have a large number of high pitch rate warnings after it was received, and later began to have a large number of high ground speed warnings. There must be something wrong here."
Wang Qiang reviewed all the warnings generated by aircraft 1566 since it was received. The aircraft had not been in service for a long time, so there were not too many QAR warnings, and it did not take long to read them all.
After looking at all of them, Wang Qiang was shocked to find that the frequency of the two warnings for the aircraft's pitch-up rate and lift-off speed was abnormally high, and there was a clear distribution of the early pitch-up rate and the later lift-off speed.
Relying on his intuition gained from years of flying, Wang Qiang felt that there must be something strange going on.
However, Wu Yong disagreed: "Are QAR warnings issued by people? What does it have to do with airplanes? If there is a problem, it is the pilot's fault."
"No, these warnings are not focused on one person or one group of people. It's possible that a small group of people don't have the right skills, but if so many people have problems, then there's something to discuss. Either there's a problem with the QAR calculation method, or there's a problem with the aircraft." Wang Qiang shouted, "No matter which one it is, it has to be solved."
Wu Yong sneered: "The QAR calculation method has been used for many years without any problems. As for the aircraft, what do you expect from the new aircraft? What if there are so many pilots who are not capable?"
With the development of civil aviation, the reliability of aircraft equipment is getting higher and higher. The consensus that talent is the main cause of problems has long been recognized by the industry. Compared with machines and mature algorithms, Wu Yong is more willing to believe that it is a technical problem of the pilots.
However, Wang Qiang's perspective was different from Wu Yong's. He said excitedly, "The pitch rate was high in the early stage, and the lift-off speed was high in the later stage. This is obviously because the pilot found that the aircraft still had a high pitch rate warning after being controlled at the normal pitch rate when flying 1566. After that, in order to reduce the high pitch rate warning, he began to deliberately slow down his pitch action. However, arbitrarily changing one's control habits can easily lead to inaccurate control problems, so that the timing of the pitch is too late to trigger the high lift-off speed warning."
I have to say that Wang Qiang is worthy of being an experienced pilot. He was able to roughly restore the problem based solely on the distribution of QAR data.
Wu Yong frowned: "What do you mean?"
"I mean that the crew's operation of plane 1566 does not match the actual change of the elevator. The actual change of the elevator is greater than the crew's operation." Wang Qiang said earnestly: "The transmission device or sensor centering device of this plane may have a congenital problem. It is best to let the maintenance staff check it out."
Wu Yong curled his lips and said, "Don't maintenance personnel do regular inspections? They didn't find any problems."
"That means the inspection was not thorough enough. For example, give 1566 a thorough inspection."
Upon hearing this, Wu Yong immediately became excited and refused on the spot: "You are crazy. Do you know how much a major inspection costs? Moreover, 1566 is scheduled to have a major inspection in five years. If you mess around like this, the aircraft maintenance plan will be completely messed up ."
“We can’t just ignore the problem, can we?” Wang Qiang argued.
Wu Yong didn't care: "It's not certain whether the problem exists or not."
Wang Qiang said anxiously: "Why don't you believe it? There must be something wrong with this plane."
"Where's the evidence?" Wu Yong was also a little annoyed by Wang Qiang: "You said there was something wrong with 1566, then you should provide evidence. Do you think it is tenable based on the QAR data?"
Wu Yong and Wang Qiang exchanged glances and comments, and the conversation gradually became more intense, even a bit like a quarrel. The other employees of the quality center did not understand why the two of them were arguing.
"Wu Yong, if there is a problem with the transmission device or the centering device of this aircraft, it will cause big problems later. We can't lose the big picture because of the small one."
"What about the money? The cost of the aircraft inspection, the cost of parking, and the loss of capacity reduction." Wu Yong's tone became colder: "Wang Qiang, why do you think there must be something wrong with 1566? What if you are wrong?"
Wang Qiang was anxious and angry: "I was wrong, and Xu Cang can't be wrong either!"
Wu Yong's eyelids jumped: "Who are you talking about?"
At the same time, in the Feibiao office, the flight training manager was really annoyed by Jin Fuli beside him and couldn't help but complain: "Captain Jin, you have been talking about being tired since yesterday."
Jin Fuli, who was leaning against the flight training manager's desk, was extremely thick-skinned. He snorted without blushing or beating his heart, "Why didn't you just agree to help me arrange the simulator earlier?"
The flight training manager had no choice but to smile bitterly: "Then you can't ask me to train an Airbus simulator for a Boeing pilot! This is a weird request that no other airline will agree to. It's not that I didn't do it on purpose, Captain Jin!"
"Does the regulation say that Boeing pilots can't fly Airbus simulators?" Jin Fuli raised his chin and said, "Is there such a rule? If there is, let me see it."
"I..." The flight training manager was about to curse, but he held it back. He still patiently explained to Jin Fuli: "Even if there is no law prohibiting this, if I arrange it, the Finance Department will not approve this expenditure, and they will cause trouble for me. Captain Jin, you can't push me into the fire pit. Besides, you arranged the Airbus simulator for a Boeing co-pilot, what on earth do you want to do?"
"Why do you care what I do?" Jin Fuli snorted , and then squeezed out a sentence from between his teeth: "Last time, didn't you ask me to bring the simulator to maintain experience? If you can help me, I will bring the simulator, how about it?"
Due to the recent sharp drop in the number of flights, many pilots are unable to maintain their experience, so they need to fly simulators to maintain their experience. However, it is very troublesome to use such simulators to maintain experience, but there are not many instructors in Blue Sky Airlines who can use simulators, which worries the flight training manager.
The flight training manager's eyes turned, this was a very constructive suggestion.
"Well, you will take care of the simulator that will keep the experience for two hours. There will be ten people in total. Once you have completed the tasks for these ten people, you can use the extra time as you wish. It is your right to decide who will fly the simulator." The flight training manager's mind was still quick: "Is this okay?"
