Chapter 16 A different checklist

Erhai Airport is located in the northwest of Jianchuan City, next to Cangshan Mountain, pillowing Erhai Lake, and surrounded by mountains and rivers. It is really a place with excellent Feng Shui. However, the Feng Shui is too strong, and sometimes the rising earth energy is not a good thing.

The so-called Meng Chun month, the weather drops, the earth's atmosphere rises, the sky and the earth are harmonious, and the grass and trees sprout. As soon as spring comes, Erhai Airport enters the windy season. It may not be obvious in the weather report, but in actual flight, the turbulence is so strong

Even experienced senior captains are intimidated.

Erhai City has extremely rich tourism resources, but ground transportation means are extremely scarce, and the only reliable air transportation is due to harsh weather conditions that airlines that have opened routes have avoided it.

Erhai Airport was originally a military airport, but its militarized use gradually faded. The local government also thought about developing civil aviation, but they interviewed several airlines in the province, but no one was willing to go there.

Unless a suitable departure airport cannot be found, Feiyu Airlines will not choose Erhai Airport for dispatch. However, it is obvious that the name of Erhai Airport has a stopping effect. Even if Feiyu Flight 6321

No matter how unconfident the captain was about landing with a single engine, he finally chose to bite the bullet and give it a try instead of making an alternate landing at Erhai Airport.

The tower controller was naturally unaware of the captain's complex and tangled psychological activities, and subconsciously felt that returning to the landing site was the first choice.

"Feiyu 6321, do you need to circle to deal with it, or do you directly turn to three sides to join the approach?" the tower controller asked.

"We are now turning right above the ML to deal with the situation. We will apply to join the approach when we are ready." The captain replied. At this moment, there is no fire alarm on the No. 2 engine, N1 is also rotating, and there is no abnormal body vibration, which is consistent with the engine starting in the air.

conditions. No matter what, they can still try to restart the No. 2 engine since the No. 1 engine is running normally.

As expected, the tower controller agreed. Now, it happened to be an intermission period between approach and departure, and the deployment pressure was much lighter, basically giving Feiyu 6321 room to perform freely.

After completing the "Engine Failure or Shutdown" checklist, I took the time to do the "After Takeoff" checklist. At this time, the aircraft was already hovering at the ML point and you could try to start the No. 2 engine in the air.

When the first officer was rummaging through the corresponding checklist, he suddenly noticed that the oil quantity indicator of the No. 2 engine displayed on the lower DU was zero. He immediately looked at the captain in confusion: "Brother, the oil of the No. 2 engine is leaking?"

The captain was startled. Following the direction pointed by the co-pilot, he also noticed the problem of oil quantity, and his expression immediately changed.

Like common household car engines, aircraft engines also need lubricating oil, otherwise the engine cannot run. Among the various reasons that can cause engine stalling, there are many lubricating oil-related contents, such as high oil temperature, low oil pressure or

Oil filter bypass. In these checklists, if the situation cannot be controlled, the "Engine Failure or Shutdown" checklist will be forwarded without exception.

In other words, problems with the lubricating oil will directly cause the engine to stall. Although the No. 2 engine has been shut down, at least there is still the possibility of restarting. If there is a problem with the lubricating oil, it means that there is no chance of restarting.

.

Even if an engine without lubricating oil is restarted, it will eventually stall within a short period of time.

If the oil is leaking, should we restart it in the air? For a moment, the captain hesitated. If he couldn't restart, he would really have to land in a single-engine crosswind.

There is no bottom.

The co-pilot felt the captain's hesitation, and his eyes were full of confusion. The checklist turned to the page "Engine Starting in the Air" but he didn't know whether to read on.

The captain wiped his face and was about to ask the co-pilot not to do the "Engine Start in the Air" checklist, but directly to do the "Single Engine Landing" checklist.

At this time, Xu Cang's voice came from behind the two of them again: "When the N2 speed is less than 8%, it is normal for the oil volume to show zero. Don't you know this?"

The captain and co-pilot turned to look at Xu Cang in unison, especially when the captain suddenly asked: "How do you know?"

Seeing the captain and co-pilot looking at him, Xu Cang couldn't help but frowned instinctively, as if at this moment he had returned to the feeling of the future chief pilot.

"Ordinary people know that they have to look ahead when driving, but you think you don't have to when driving a plane?" Xu Cang said coldly.

The captain and co-pilot were both shocked. They immediately realized that they had forgotten to monitor the status of the aircraft due to their surprise. They were immediately ashamed and turned their heads back.

The lecturing tone and demeanor of the young man sitting behind him reminded the captain of the inspectors sent by the bureau during random inspections. They were exactly the same.

"Is he the authorized representative of Blue Sky Airlines?" The captain muttered in his mind: "But why don't I remember that Blue Sky Airlines has such a young authorized representative of the Authority?"

Appointed representatives of the bureau are scarce in any airline, and basically everyone knows it. But Xu Cang looked very arrogant. However, in the captain's opinion, this demeanor was stronger than that of some bureau people he knew.

a lot of.

Seeing that the two people present were all following his words, Xu Cang's face brightened a little, and he said leisurely: "This should be explained in the notes on Boeing's checklist, but you don't know about it?"

"Is there such a note? No!" The co-pilot flipped through the "Engine Air Start" checklist from beginning to end several times but found no relevant description.

"No?" This time it was Xu Cang's turn not to understand. This remark should be very common and it is impossible not to have it.

The co-pilot looked at the captain, obviously hoping to let the captain make the decision. However, looking at the captain's face, he was also full of tangles in his heart.

The reason why the unit is in such trouble lies in the purpose of engine protection. Sometimes the harm caused by a simple engine stall is controllable, and if the maintenance personnel can repair it, the loss is not as big as imagined.

However, if the engine is forcibly started without lubricating oil and there is no lubrication between the engine parts, this situation will cause extremely terrible damage to the engine. In severe cases, the engine may be scrapped.

If the captain believed Xu Cang, there was no basis in the checklist, which meant that he would be responsible for any subsequent problems. The captain felt that he was unable to handle the risk of scrapping an engine.

Just when the captain thought it was safe, Xu Cang, who pondered for a moment, suddenly asked: "Is there an English version of QRH? Take it out and take a look."
