If you want to reduce the load, you need to contact the maintenance to reopen the cargo hold, and the whole process will take about 20 minutes, which is just the right time to make a manifest for stowage.

After waiting for about a quarter of an hour, the person who delivered the manifest came in a pickup truck. Xu Qing beckoned to the man, signaling him to come to the right, and after waiting for someone to come, Xu Qing opened the side window, yes, the side windows on both sides of the Boeing 737 can be opened, and then Xu Qing leaned out half of his body and put the headphones down.

The person who delivered the manifest was also an old fritter, so he didn't need Xu Qing, he clamped the manifest on the headset buckle, and then Xu Qing pulled the headset up.

After pulling a lot of goods down, Xu Qing compared the data of the new manifest and calculated that he could take off in a normal form.

After waiting for the cargo door to close, Xu Qing reported the release: "Blue 9271, parking stand 120, ready!" ”

"Blue 9271, contact apron 121.6, goodbye!" The release allows the transfer frequency to the apron, and there is no flow control.

Xu Qing transferred the frequency to the apron frequency, and at the same time contacted the apron: "Hello apron, blue 9271, parking stand 120, ready." ”

"Blue 9271, you can push out and drive, head south!" The apron gives the launch of the start-up instruction.

"Blue 9271, our APU has some problems and needs to start the second engine on the spot first!" In Xu Qingming's case, this special starting procedure needs to be communicated with the apron in advance, otherwise it may affect the ramp deployment, and the airport will be held responsible.

"Blue 9271, you can drive on the spot, you can push the newspaper!" Apron Road.

"Drive where you are, push away the newspaper!" Xu Qing replied.

At this time, it is necessary for the captain to communicate with the maintenance, and it should be noted that radio communication is not the same as the maintenance communication. Generally speaking, only the captain can communicate with the maintenance, and the button to talk to the maintenance is not the same, which is under the radio communication button.

Before communicating with the maintenance, you need to do the pre-start procedure, that is, turn on the anti-collision light, open the fuel pump electric door, and turn on and off the central oil pump according to the situation.

This is mainly to prevent too little fuel, which fluctuates during strenuous exercise, especially during takeoff, causing the low fuel lamp to shine intermittently.

The flashing of this low oil level lamp may cause the main warning light to turn on.

Think about it, during the tense stage of take-off and running or the initial climb of take-off, the main alert suddenly turns on, and the heart attack can be scared.

In addition, it is necessary to turn off the A hydraulic system, which is to remove the front wheel hydraulics, otherwise it is inconvenient to push out.

Turning on the anti-collision light is also a signal to the maintenance, and the maintenance is to see the anti-collision light to remove the wheel block and hang the trailer.

"Captain, make sure you stop and brake?" The sound of aircraft maintenance rang out in the cockpit.

"The brakes are on, and the air source car is called?" Often the instructor and the maintenance of the machine.

Normally, you need to release the brakes before pushing away, but this time you need to drive in place first, so you can't let go of the brakes.

"The air source car is ready, and you can start the second engine!" Maintenance Road.

Instructor Chang looked at the pressure of the pipeline, confirmed that the gas had been supplied, and asked Xu Qing to set the starting configuration.

This time, the starting configuration is not much different from the normal one, that is, the double component is closed, and the isolation valve is automatic. The isolation valve is automatic, which is to conduct the air supply from the second engine to the first engine after that for starting. The only difference in the configuration is the closing of the APU bleed gate.

"Good configuration, second shot ground position!" Xu Qing turned the starting gate to the ground position, which is no different from the normal starting procedure.

The No. 2 engine starts stably through the ground air source, and starts the alternate bleed air after the second engine is stabilized.

"The second engine is operating normally, and the air source car can be withdrawn." Often the instructor and the maintenance of the machine.

You can use the second bleed air to start a start, the ground air source car does not need it, and you also need to add the throttle of the second engine for a while, you need to ensure that there is no one behind the engine, otherwise it is easy to be blown away by the engine tail jet.

"The air source car is withdrawn, please release the brakes in the cockpit, and the trailer is hanged!" Maintenance Road.

After the second start is good, it can be launched, and the cross-infusion induced air start cannot be carried out during the launch period, and it is necessary to wait until the push is in place to start a launch.

"Blue 9271, the second engine starts in situ, apply for launch, start one shot!" Xu Qing reported to the apron, and the apron had also asked them to report when they could launch it.

"Blue 9271, you can push it out, start it!" The apron immediately gave permission to launch the car.

At the moment when the apron agreed to launch, Chang Instructor contacted the maintenance: "The brakes are loose, you can push, and the head is facing south!" ”

"Roll out received, head south!"

The plane is slowly pushed out of the parking stand, and after it has come to a complete stop, the instructor sets the stop brake.

"The plane is pushed into place, please set the stop brake in the cockpit!" Maintenance Road.

"Brake and start!"

"The ground equipment and ground personnel have been moved out of the way, and they can start a shot!" The maintenance also knows the procedure of alternate bleed air, and the rear of the engine in the cockpit has been cleaned in advance.

"Confirm the configuration, the engine bleed air valve opens, the APU bleed electric valve closes, the dual-component electric gate closes, and the isolation valve valve is automatic!" Xu Qing confirmed the configuration again, it was the first time he had done this alternating infusion induced air start, and he was still quite cautious.

Instructor Chang naturally knew whether the starting configuration was right or not, but Xu Qingxin was cautious and slow, and it was not an emergency, so there was no need to race against time.

"I'm starting to get on the gas!" Instructor Chang said a sentence and began to gradually increase the second throttle, so as to increase the gas supply and achieve sufficient pipeline pressure.

XU QING HAS BEEN PAYING ATTENTION TO THE PIPELINE PRESSURE INDICATOR, AND WHEN THE PIPELINE PRESSURE REACHES 30 PEI, HE IMMEDIATELY SAYS: "PIPELINE PRESSURE 30PSI!" ”

Teacher Chang continued: "As soon as the electric door is activated, the ground position!" ”

Xu Qing shifted the starting valve of the first engine to the ground position, and during this period, the thrust of the second engine must be kept still to maintain sufficient air supply.

The starting data of the first shot is normal, and it is not until the EGT red line disappears and the first shot is stable.

After the first shot is stabilized, the second shot is retracted to the slow train.

"The engine starts normally, watch the gestures slide out, goodbye!" After the instructor said goodbye to the maintenance, the maintenance could pull out the headphones and leave.

"Let's apply to slide out first, it's raining outside!" Teacher Chang said.

Normally, the engine starts well to do the pre-coasting procedure, and then the pre-taxiing checklist. After Xu Qing did the pre-taxiing procedures, Instructor Chang saw that it was raining heavily outside and wanted to leave early, so that the maintenance could go back. Otherwise, if the plane does not slide out, the maintenance will have to wait on the side.

"Blue 9271, apply to slide out!" Xu Qing applied to slide out with the apron.

"Blue 9271, wait in place first, there is a carry!" The apron did not agree to Xu Qing's application to slide out.
