"It's time to push out and drive!" Xu Qing said to Zhang Qijun.

Zhang Qijun just nodded, at this time, the maintenance hung up the trailer, removed the wheel gear, and contacted the cockpit: "Captain, the trailer is hanged, and the brakes can be released." ”

Zhang Qijun released the stop brake on his foot, and replied to the machine service: "The brake is loose, you can push!" ”

"Great!" The maintenance gave a gesture to the tow driver, and the trailer started and began to push the plane back.

This is followed by alternating bleed air starting, which uses the power supplied by engine No. 1 and the addition of air to start engine No. 2.

The first sentence in FCOM's engine alternate-bleed air starting program is not to complete the alternating bleed air start during the roll-out period, and to wait until it is pushed in place before starting the alternating bleed air start. Therefore, Zhang Qijun and the maintenance did not mention the matter of starting the engine during the launch.

During the rollout, Xu Qing put the iPAd in the chapter of FCOM's engine alternate bleed air starting, although he was already familiar with the alternating bleed air starting procedure, but it was also a good choice to put the program aside for reference. There is no stipulation that the cross-infusion induced air start must be completed by memory.

In contrast, from beginning to end, Zhang Qijun has not looked at the program of engine cross-induced air starting, and the captain is really different.

The plane was pushed into place, and the maintenance noticed: "Captain, pushed in place, please set the brakes!" ”

"Brake!" Zhang Qijun set the stop brake and contacted the maintenance again: "Then start the second shot!" ”

"You can start a second shot!"

Since the No. 1 engine will supply the charge air to the No. 2 starter for a while, it is necessary to add some throttle to make the pipe pressure greater than 30 PSI. Once the aero engine increases the throttle, the air flow that is sprayed is quite strong, it is easy to blow the wind, if the person is close, there is no danger, so the procedure of cross-drawn air start clearly states that no one behind the engine should be ensured before starting.

Zhang Qijun knew this very well, and said to the maintenance before starting: "There is no one behind the engine!" ”

"No, don't worry, it's all withdrawn just now!" The maintenance also knew the procedure, and Zhang Qijun had already kept people away from the engine before he could say it.

"Okay, then I'll start the second shot."

After Zhang Qijun communicated with the maintenance, he gave Xu Qing a look. Xu Qing understood and began to do the action of infusion and induction.

Open the engine bleed valve, close the APU bleed valve, close the component valve, and isolate the flap in the automatic position. This isolation valve is the passage that supplies the charge air of engine 1 to engine 2 and must not be closed.

The APU bleed air valve has just been closed when the ground air source starts, and the other configurations are the configuration of the normal engine starting program, that is, the APU bleed air valve is open in the normal program, that is, the APU bleed air valve is used as the engine starting through the APU bleed air gate. However, now that the APU is unusable, it is natural that the APU bleed gas gate will be closed.

After the starting configuration was completed, Zhang Qijun nodded, he had been watching Xu Qing's movements, for fear that there would be a problem with the starting configuration. However, Xu Qing started the starting configuration, and he was still handy without the slightest delay.

Looking at the starting configuration, there is no problem, Zhang Qijun said: "I have stepped on the accelerator, you look at the pipeline pressure." ”

Xu Qing nodded, and as Zhang Qijun began to add the thrust of the No. 1 engine, the pressure of the pipeline began to increase slowly. Xu Qing saw the scale clearly, and waited until the pointer of the pipe pressure exceeded the thirty scale, and then said: "Brother, it's over thirty!" ”

Zhang Qijun raised his head to check the pressure of the pipeline, and after confirming that it was correct, he kept the throttle lever pushed forward and commanded: "The second ground position!" ”

Xu Qing put the starting valve of the No. 2 engine on the ground, which is no different from the normal starting procedure.

Xu Qing and Zhang Qijun have been paying attention to the data parameters of the engine starting stage, and at the same time paying attention to the changes in the pressure of the lower pipeline from time to time.

As the N2 reached 25%, Zhang Qijun lifted the starting handle of the No. 2 engine, and Xu Qing shouted: "Fuel flow, EGT, oil pressure rise!" ”

Fuel flow, EGT, and oil pressure are all data that need to be paid attention to during engine starting, and any abnormality in any one of these data may cause engine starting failure.

When N2 reaches 56%, the engine starter automatically jumps to the closed position as promised, the starter is disengaged, the pipe pressure begins to drop, and the engine starter valve is closed. By the time the red line on the EGT indicator disappears, the EGT temperature begins to drop and stabilize, marking the completion of engine number two.

Zhang Qijun saw that the No. 2 engine was in a stable state, and began to retract the thrust rod of the No. 1 engine, and received the position of the slow train all the way, so that the two engines had started normally.

"Double steady, flap five, do the move!" After Zhang Qijun closed the throttle of the No. 1 engine, he began to instruct Xu Qing to do the action program before taxiing.

Placing the flap to flap five is the first one, and then the engine-driven generator is turned on. Although Zhang Qijun and Xu Qing are very skilled in operation, they are a little burdensome after all, and there is still a kind of relief after all the operation, and for a while I forgot that the generator driven by the No. 2 engine had a history of failure.

The generator driven by engine 1 was connected before, but now it only needs to be connected to the generator driven by engine 2. Xu Qing forgot the history of the failure of the No. 2 generator, and connected the No. 2 generator as if nothing happened, but he didn't notice it at the time, and only realized it after connecting the No. 2 engine.

"I'll go, I'm fine." After Xu Qing reacted, he realized that the No. 2 generator had been connected, and then Xu Qing's hand was still hovering over the No. 2 generator electric door for a while, and after waiting for two seconds, after confirming that the No. 2 generator was connected, Xu Qing and Zhang Qijun, who also reacted, breathed a sigh of relief without a trace in their hearts.

Without this worry, Xu Qing was a lot happier when he started the procedure, and Zhang Qijun finally said to the maintenance with confidence: "The double engine is normal, look at the gesture and slide out goodbye." ”

"The second generator is fine." This maintenance should have been said by the one who just came up.

Zhang Qijun: "It's okay, no problem. ”

"Okay, then I see your gestures."

Xu Qing could even hear the sound of the maintenance pulling out the headphones, but when the program achieved the continuous position of the engine starting the electric door, it was the crisp and subtle sound of the electric door jumping open. Xu Qing chuckled in his heart, and looked up directly at the indicator light of the generator driven by the No. 2 engine.

At this time, the light of the switch bus bar is not on, but the source disconnect light and the generator disconnect bus bar light are on, and after two seconds, the system signal board and the main warning light are on.

Generator No. 2 jumped away again! However, this time, because there is a No. 1 generator, there will be no power outage. It's just that the worst fears have happened.

What are you afraid of, what are you afraid of!

"This ...... Shall I just pick it up again? Xu Qing turned his inquiring gaze to Zhang Qijun.

Zhang Qijun didn't speak, and directly connected the electric door of the No. 2 generator. I tried it once and it still didn't respond, that is, the electricity was not connected.

"Don't mess with me!" Zhang Qijun muttered, tried again, but it still didn't work. Zhang Qijun didn't give up, tried the third time, and this time he picked it up.

Although it was connected, Xu Qing and Zhang Qijun looked at me, I looked at you, and fell into silence for a while. Xu Qing's pre-taxi procedure had been completed, but the two of them had not done the pre-taxi checklist because the two of them were already thinking about whether to go or not.

That's right, the two of them were really thinking about whether to go.

Xu Qing just habitually glanced at the captain and asked the captain for his opinion, which was the normal reaction of the co-pilot, but Zhang Qijun looked at Xu Qing for a long time.

"Brother, don't keep looking at me, this can't be on me." Xu Qing was very uncomfortable being stared at for a long time, as if it was his own reason.

Regarding Xu Qing's self-whitewashing, Zhang Qijun didn't say a word, he sniffed, retracted his gaze, and contacted him for release: "Release, Xingfei 8342, there are some problems with the plane on my side, let's deal with it on the spot first." ”

There is a problem with the generator driven by the engine, which needs to be called to the maintenance to deal with it, and it will not be able to go for a while. After the launch, you can't slide for a long time, so you need to talk to the control.

"Xingfei 8342, now that the apron frequency is on, you should contact the apron 121.85 first and explain the situation to the apron." Releases didn't care about it, but pushed the matter to the ramp control.

Xu Qing and the others were not surprised, the operation on the apron such as launching and driving should have been the jurisdiction of the apron control, and when they were allowed to launch the car, they were also surprised, when the release control was in charge of the launch of the car.

Now listening to the release control, it should be that they took off relatively early, the ramp frequency has not yet opened, and the release control is only a temporary part-time role of apron control. Now that the ramp control has reopened, it is natural that the areas of responsibility will be clearly delineated.

"Apron 121.85, Xingfei 8342." Xu Qing replied.

Xu Qing adjusted the frequency to 121.85 and contacted the apron control: "Hello apron, Xingfei 8342, I'm with you for a long time." ”

"Xingfei 8342, what's the problem with your plane?" Obviously, at the time of the release control, Xu Qing's situation was told to the apron control at the time of handover.

At this time, it was Zhang Qijun who spoke: "There are some problems with the electrical system on our side, and we need to consult the maintenance first before making a decision." ”

Zhang Qijun and Xu Qing are most worried about whether their position will have an impact on other planes that launch and taxi, and if so, then they will have a limited time to deal with the problem.

"Does where we are now make a difference?" Xu Qing asked.

Zhang Qijun and Xu Qing both waited with bated breath for the answer to the apron control, if it didn't affect them, they would have enough time to make decisions, otherwise they would have been chased with a whip, and it would be really uncomfortable.

The apron control side was silent for two seconds, probably assessing, and after waiting for a while, he replied: "Your position has no effect, just report it to me after you are done." ”

Xu Qing: "Okay. ”

Just now, the maintenance had already pulled out the headphones and left, and at this time, he was not far from Xu Qing's side, looking at the direction of the plane. It's been a long time since I've been activating, so why haven't I made a sliding gesture yet? Although the sun has only been up for a long time, it is not a problem to be basking like this all the time.

It's okay to talk about moving normally just now, what the hell is the ink. Didn't they just say that the generator was fine? So what's the reason to wait?

He didn't know what Xingfei Airlines' salary calculation for ground taxiing was, but then again, no matter how he calculated, the plane didn't move now, which meant that the taxiing had not started, and no matter how much he grinded, there would be no penny.

The sign of the beginning of the taxiing of the plane is that the aircraft begins to move by its own power, note that it is its own power, so it is pushed away by the trailer Although the plane moves, it is still not considered an airplane taxiing. So, the maintenance did not understand what the crew was waiting for. In the early morning, hurry up and send the plane away, and you can rest for a while!

Understand! Well?

The maintenance suddenly frowned, pushed the colleague next to him, and pointed in the direction of the plane: "What kind of gesture is that?" ”

The colleague next to him was a little impatient, and looked in the direction pointed by the maintenance officer, and saw that in the cockpit, the co-pilot had been waving desperately, and his gestures were chaotic.

"Is this a gliding gesture? No way! The two crew members looked at each other, and they really couldn't understand what the co-pilot wanted to express.

One of the mechanics was not very confident and said: "This co-pilot is a rookie, isn't it?" Can't even make a glide gesture? ”

"Rookie, you're big, this is a two-person crew, can the newcomer fly with the captain? Do you have a brain? The colleague scoffed.

"What does that mean by that?" The machine maintenance spread his hands, and the dead pig was not afraid of boiling water.

emmm.....

The colleague was silent for a long time, but he still couldn't answer, Xu Qing's gesture was indeed beyond the scope of their knowledge.

To be honest, they have thought about the past and asked closely, but if the co-pilot is not wrong, but it is just a gesture that they have not seen or don't know, then wouldn't it seem that they were very unprofessional in the past? That's a shame!

Therefore, the two aircraft operations are also a little entangled.

In the cockpit, the green tendons on Xu Qing's head were about to burst out. They can't understand the gesture of beckoning them to come over so obviously? Is it hard to understand?

Looking from the side window, the two aircraft attendants were still talking to each other over there, and I didn't know what they were muttering, so they couldn't be chatting.

Even Zhang Qijun on the left couldn't stand it, and said irritably: "Two blind people can't make it? ”

How can a mechanic be blind? It's just that the maintenance and Xu Qing's brain circuits are not on the same channel at all. The maintenance was wondering if Xu Qing's gesture was a rare gesture. And Xu Qing is the most direct and simple gesture to wave to them and let them come over.

It's complicated to think about machine maintenance.

Xu Qing saw that the aircraft maintenance was stunned and did not move, so he simply opened the side window and shouted at the top of his voice: "Come here." ”

Because he was too hard, Xu Qing finished shouting, only to feel dizzy and swollen, and his skull hurt badly.
