Joining Sichuan Airlines starts with rescuing the captain of a powerful country

Chapter 23 Complete the queuing procedure before landing, the airport runway is close at hand

As the city with the first economic ranking in Bulk Province.

Meiyou Airport should be considered the only pain point in Suzhou.

From ancient times to the present.

The idea that there is heaven above and Suzhou and Hangzhou below has long been deeply rooted in the hearts of the people.

But the grand Suzhou doesn’t even have an airport.

but it does not matter.

Meiyou Airport is unreliable.

Hongqiao Airport is also wide.

Flight 3u8874's turn to the left was not a temporary change of direction and was preparing to land at another airport.

It's just flying 'five sides'.

Again.

Taking off and landing are the most dangerous and tedious processes in the entire flight.

When the plane lands, it does not aim directly at the runway and land directly.

Because most military and civilian airports around the world only have one runway.

Domestic words.

Shanghai Pudong Airport has the most runways, with five.

The capital Daxing International Airport has four runways.

As for a few airports such as Capital International Airport and Shancheng Jiangbei International Airport, they only have three runways.

Generally, provincial capital cities and particularly developed first-tier cities will build dual-runway airports, such as Yangcheng, Pengcheng, Jiangcheng, Xingcheng, Chang'an, Rongcheng, etc.

However, there are also many airports in provincial capital cities and second-tier cities with only one runway, such as Qianyang, Jincheng, Jinyang, etc.

Airports in so many provincial capitals and second-tier cities have only one runway.

Not to mention other smaller airports.

But even if Pudong Airport has five runways, it cannot handle the takeoffs and landings of so many flights at the same time.

To know.

The average daily flight takeoffs and landings at Pudong International Airport are around 2000.

In other words.

On average, 2000 flights land or take off at Pudong Airport every day.

Only 5 runways.

Can it accommodate the takeoffs and landings of so many flights at the same time? !

Obviously not.

What should I do if so many planes arrive at the airport at the same time and are waiting to land? !

First come first served? !
  Obviously not.

If it were really first come first served, wouldn't it be a mess? !
  Therefore, in order to ensure the safety of all aircraft and avoid flight accidents such as collisions, all aircraft must be lined up to take off/land in an orderly manner.

But airplanes cannot park directly on the road like cars.

The current level of human science and technology is not yet capable of suspending an aircraft weighing dozens of tons in mid-air.

So how to avoid a tragic collision between high-speed aircraft in the air? !

The answer is simple.

Fly 'three-sided' or 'five-sided'.

What are 'three sides' and 'five sides'? !

'Three-sided' and 'five-sided' flying is an important course for training pilots. To put it bluntly, it means flying a rectangular route (three-dimensional) around the airport, which is called a take-off and landing route in terminology.

This way they can take off and land in an orderly manner without bumping into each other.

'Three sides' means that when the aircraft is in the air, whether it is landing or leaving the airport, it must draw a complete rectangle in the air to avoid collision with other aircraft.

So you need to turn left, turn left, and turn left again (or turn right, turn right, and turn right again).

The second left turn flight phase is the 'three sides'.

At this time, the aircraft is just in the downwind stage, so it is called the leeward side.

As for the 'fifth side', it means one side (the departure side), the second side (the crosswind side), the third side (the leeward side), the fourth side (the baseline side), and the fifth side (the final approach).

After the final flight, we have almost circled the airport.

The passenger plane continued to decrease in altitude while flying the final leg. By the time it finished flying the last leg, the aircraft was only a few hundred meters high and could visually see the airport runway.

At this time, you can land directly.

When a passenger aircraft is flying three or five directions, it needs to constantly contact the approach controller and constantly adjust the aircraft's altitude and flight attitude according to the approach controller's instructions.

Even the airspeed is strictly controlled by the approach controller. In other words, at this time, the approach controller is the god of all passenger aircraft taking off and landing.

Whatever he said was what he said, and there was no room for bargaining.

Flight 3u8874 is currently turning to the left, which means that it has already started waiting in line and is preparing to land.

It’s just that the queues for airplanes are different from those for cars.

It's just that we need to keep circling around the airport.

soon.

The approach controller once again conveyed a new instruction, "Sichuan Airlines 8874, maintain altitude 900."

Liang Dong immediately repeated, "Hold at altitude 900, Sichuan Airlines 8874."

"8874, turn left to heading 070, you can approach with 04R blind landing." The approach controller's voice sounded again.

This means that flight 3u8874 has completed one side of its 'three sides'.

"Turn left to route 070, you can make a 04R blind landing approach, Sichuan Airlines 8874." Liang Dong was still the emotionless repeater.

Lu Qingzhou gently turned the operating lever.

Then he glanced at the instrument panel and then said, "Our speed is still a bit fast. Let go of the flaps and open the spoilers to reduce the airspeed. Remember to remind me to put the spoilers back to the armed mode before landing." .”

"Understood." Liang Dong spoke while moving his hands slowly.

He is indeed an experienced co-pilot who has been flying for four or five years.

Both technology and experience are worthy of trust.

"Sichuan Airlines 8874, maintain speed 180, 8 nautical miles to the final side."

"Keep the speed at 180, 8 nautical miles to the final side, 8874 received."

Another round of dialogue is completed.

Lu Qingzhou immediately took response actions according to the instructions of the approach controller.

Flying a commercial airliner is neither difficult nor easy.

Why do you say that? !

Because if nothing else, just identifying so many complicated instruments is enough to give people a headache.

In addition, you need a big heart to be able to face all crises calmly and calmly.

Excellent physical fitness and strong learning ability
  Therefore, the above conditions are enough to keep most people out.

But even so.

Flying a plane is not as difficult as imagined
  Because modern technology has become very advanced, artificial intelligence has long been applied to the passenger aircraft itself.

Therefore, civil aviation aircraft are in autopilot mode most of the time during flight.

Even when landing, the pilot can choose the ILS (Invisible Landing) system to assist the landing.

But no matter how advanced artificial intelligence is, how can it be as reliable as humans themselves? !

So whether it is autonomous driving mode or ILS (blind landing) system.

They can only play a supporting role.

The only thing we can truly rely on is human beings themselves.

After all, a passenger plane is related to the life safety of dozens, hundreds, or even hundreds of people. Is it possible for this industry to entrust all the lives of so many people to artificial intelligence? !
  This highlights the importance of pilots.

otherwise.

Why do pilots get so much salary? !
  "Sichuan Airlines 8874, turn left to heading 140, maintain altitude 500." The approach controller's voice rang through the communication channel again.

Liang Dong's emotionless repeater repeated again, "Turn left to heading 140, maintain altitude 500, Sichuan Airlines 8874."

Lu Qingzhou gently pushed the operating lever again, while simultaneously raising the right wing and pressing down the left wing.

The nose of this Airbus A319 passenger plane once again completed its turn.

This time.

The nose of the passenger plane has been completely pointed at Hongqiao Airport in the distance.

This also means.

Flight 3u8874 has completed the 'three sides'.

The queuing procedure before landing has been completed.

Hongqiao International Airport runway.

It's also very close.
