Because of the special advance of the instructor, the parking stand was next to the security checkpoint, and when I got under the plane, there were still about 70 minutes before the take-off time.

From the moment he got off the train, Xu Qingdu followed behind Instructor Chang, what Instructor Chang did, he did what he did, and it was still the safest way for beginners to draw gourds.

When he got under the plane, Xu Qing wore a reflective vest for the first time as usual.

The area where the airport is located is a restricted area, and people are not allowed to move around.

All activities at the airport, in addition to complete documents, must also wear reflective vests, and must be checked before each flight.

According to the regulations, the inspection of the aircraft starts with the left front fuselage, and then follows the plane to check around.

Instructor Chang explained to Xu Qing some key points of the inspection around the machine.

There is a detailed description of the circumambulation inspection in the SOP, and there is no problem in checking them one by one according to the listed items, but where there are key points, some of the more prone to problems need to be paid attention to.

First of all, the nose lightning strike point!

This is especially the case in the summer when thunderstorms are frequent, because lightning strikes involve penalties. Before the flight, it must be confirmed that there are no lightning strikes or that the lightning strikes have been dealt with, otherwise, it is easy to carry the blame for others.

Secondly, the inspection of the engine!

This mainly checks whether the engine blades are missing or damaged, and whether there are foreign objects in the engine cavity. After all, it's been more than one time that passengers have been thrown coins into the engine.

In addition, whether the body is damaged, whether the tire tooth marks have been smoothed, whether there is oil dripping, and whether the tail pry is worn.

Here is a special mention of the tail pry, not that the tail pry in the green zone indicates that the tail is not wiped. Sometimes, after wiping the tail of the aircraft, the tail skid will fall down under the action of gravity and return to the green zone. Therefore, it is not only necessary to see whether the tail skid is in the green zone, but also to see whether the tail skid is really worn.

Wiping the tail of the machine is a more serious incident, once the crew and maintenance are not found, the black pot on the back will be a big deal.

This time, the teacher asked that pair to only be responsible for filling in the book, and Xu Qing would complete everything else.

Once the circumnavigation inspection is complete, the cockpit is ready to be prepared.

For this kind of student who has not been in the class for a few days, the general instructor is reluctant to take it, because it is too troublesome. You need to supervise at all times, and if you accidentally turn the wrong switch or adjust the height wrong, it will be a big loss.

Therefore, it is extremely energy-consuming to take students, especially low-level students. Many instructors politely refuse when a student asks to sit down. It's also thanks to Teacher Chang to take Xu Qing as an apprentice, otherwise who has the patience?

Cockpit preparation Xu Qing has done it many times on the simulator, and he is quite proficient. But after all, it was replaced by a real machine, and I was careful to flip each switch, for fear that something would go wrong and something would go wrong. This is not a simulator, and there is no chance of doing it all over again.

Teacher Chang sat in the observer's seat, staring at Xu Qing's movements the whole time.

Even though Xu Qing had practiced countless times on the simulator, there was still a problem on the real machine.

The problem lies in the switch for the cooling of the device!

Device cooling does not turn off this option, only normal and standby bits. Generally speaking, the switches on and off the aircraft panels are downward, such as yaw damping, oil pump, windshield heating, hydraulics, etc.

Some rare three-phase switches, such as component switches, are available in automatic, off, and high-flow positions. For example, the isolation valve has three positions: open, closed, and automatic.

One or two electric valves are in the middle position when taking off, that is, the automatic position of the component electric valve and the automatic position of the isolation valve.

Rarely, there are APU bleed valves and APU valves, which are in the closed position after the engine has been started.

Because the power supply and charge air required for engine starting, the APU is normally provided. Once the engine is started, it can be powered by the engine's generator, as well as the engine bleed air.

The pre-coasting procedure after the engine has been started consists of two steps: closing the APU bleed air and the APU valve.

This is easier to understand, close up, open down.

However, the electric door cooled by the equipment is the normal position at the top and the backup position at the bottom, so most of the time the electric door is upward, which is very abrupt. Some people are not ready to accidentally get all the dates downward, and that is wrong.

Xu Qing didn't know if it was because he was nervous, or if he was just a handful, and he got the electric door of the equipment cooling to the spare position. Teacher Chang didn't keep quiet, just see if Xu Qing would check.

When the simulator was modified, he repeatedly emphasized that when the low number was low, the program would inevitably be negligent, and it was necessary to develop the habit of going back and checking. He wanted to see if Xu Qing remembered his words.

Although Xu Qing was nervous, he did not forget the previous teaching of Teacher Chang, except for the CDU who did not fight, after the rest was finished, he went through it from top to bottom.

This review was even more careful than the first time, because he knew that because he was sitting for the first time, he was excited and nervous, and his mind was a little empty, and it was really possible to miss something. Now calm down, and review carefully.

Instructor Chang nodded again and again in the back, even if Xu Qing didn't find the error of the equipment cooling later, he could accept it. After all, attitude is everything, and if you can remember what you say and have a good behavior habit, you won't have big problems in the future.

However, Instructor Chang still underestimated Xu Qing, and Xu Qing, who calmed down, carefully checked every electric door. There was a noticeable pause when it was the turn of the device to cool down.

As soon as the two signs of NORM and ALT went up, he was not illiterate, so he naturally knew what it meant, and of course he knew that normal should be in NORM. When it was time to modify the simulator, he would turn the electric gate to the NORM position without saying a word, but now he hesitated.

Could it be that I forgot something? That's why you just put the electric gate in the spare position?

Thinking about it, Xu Qing looked through the plane fault sheet of the release data again, confirmed that there was no problem with the cooling of the equipment, and then hesitantly put the electric door in the normal position.

Teacher Chang smiled secretly when he saw it in the back, and the panel was almost ready, so he sat in the left seat, and after a while, xu qing was going to hit the cdu, and he was going to star.

What Instructor Chang didn't expect was that Xu Qing hit the CDU very quickly, and there was no mistake, but he was a little hesitant when choosing the landing runway in X City.

City X Airport is operating on dual runways, 05L, 23R, and 05R, 23L.

At that time, the wind shown in the METAR newspaper was 220/03, so it must have been runway 23, and the key was 23L or 23R.

There is no problem with the approach procedure, 23L and 23R share the same approach, both enter from the NSH direction, and even the transition point is the same.

"Let's pick 23L!" Teacher Chang said directly to Xu Qing.

Every airport landing and take-off runway will have certain rules to follow, and it is not a blind guess.
