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

Chapter 261: Is the captain out of his mind? Why are three emergency codes with different meanings sent in succession?
cockpit.

Liang Dong's gloomy face finally gained a hint of expression.

It's confusion.

That's right.

Now Liang Dong looked at Lu Qingzhou with a confused and confused expression.

Big brother.

When did this happen?

What's the use of hanging the emergency code again?

And there are three emergency codes in a row.

The key is.

You actually emphasized that the order cannot be wrong.

What kind of crazy orders are these?
Is your old brain frozen?

Otherwise, why would you issue such a confusing order?
mentioned before.

Air traffic control on the ground uses transponder codes to identify each aircraft in the air.

The transponder code acts as a 'temporary identity card' for each aircraft.

The ground air traffic control department uses the aircraft's "temporary ID card" to distinguish each aircraft in the sky.

If the aircraft changes to an emergency code, ground air traffic control will know what danger the aircraft is encountering through the emergency code.

When an airplane is flying in the sky, it is almost always alone if it encounters danger.

We can only rely on guidance from the ground to get out of the crisis.

But what if even the communication system fails and effective communication is no longer possible?

You can only rely on the emergency code to call for help urgently.

There are 6 common aircraft emergency codes in the world, namely 1200, 1255, 1277, 2000, 7500, 7600 and 7700.

The meaning expressed by 1200 is 'visual flight without designated transponder', in other words, 'transponder failure'.

As for 1255 and 1277, they are relatively special codes. They mean "private plane" and have no other meanings.

2000 means that the administrator did not give a code, which means that the aircraft does not have its own 'identity document' during the flight. This emergency code is not common and is not often used.

7500 means that the aircraft encountered an emergency situation - illegal interference.

It refers to a plane being hijacked or the plane being in danger of being hijacked.

Ground air traffic control receives the '7500' emergency code issued by the aircraft and needs to respond quickly.

7600 is a communication failure, communication failure or radio disconnection.

Because there are many unexpected situations in the sky that may sometimes interfere with communications, if the aircraft cannot contact the ground air traffic control, it needs to send the '7600' emergency code to the ground air traffic control so that the air traffic control can respond.

7700 is the most frequently used emergency code and is also the most frequently used emergency code.

It means there was an emergency on the plane.

This emergency situation not only includes mechanical failure of the aircraft, but may also indicate sudden illness of someone on the aircraft, or other emergencies.

If a flight issues the '7700' emergency code, air traffic control will immediately distinguish the flight from other flights to facilitate the notification of relevant civil aviation units for emergency support.

Now Lu Qingzhou ordered Liang Dong, who was sitting in the co-pilot's seat, to send three emergency codes: 600, 7700, and 7500 in sequence.

This is completely contrary to common sense.

How can a plane send out three emergency codes in a row?

not to mention.

The meanings expressed by these three emergency codes are completely different from each other.

So Liang Dong had every reason to doubt whether the captain's head was frozen.

Because Lu Qingzhou's order cannot be said to be very rare, it should be unprecedented, and perhaps unprecedented.

It's completely inconsistent with the standard procedure for passenger aircraft to call for help.

but.

Lu Qingzhou seemed to have no intention of explaining.

He is still looking straight ahead, holding the control rod with one hand and pushing the throttle valve with the other hand. Firmly control the flight attitude of the aircraft.

Liang Dong saw this.

He shook his head helplessly.

Since the captain was not going to explain, he could only give unconditional orders.

The captain is the absolute authority on the aircraft.

And the more dangerous it is, the less you can question the captain's orders.

Even if the captain wants to lead everyone into the endless abyss, the second captain and first officer can only grit their teeth and obey.

Because resistance will only make an already bad situation worse.

The unity brought about by absolute obedience may have a glimmer of hope.

Liang Dong shivered and stretched out his hand, pressing the answering machine.

More than 10 seconds later.

Three emergency codes with completely different meanings followed the flow of radio waves, starting from flight 3u3, and sent them in all directions.

Rongcheng.

In the control hall.

A controller suddenly shouted, "Director, we have received another emergency code from 8633."

Gao Ge immediately turned his head.

Without waiting for him to ask.

The controller suddenly let out a soft sigh, with confusion written all over his face, "Huh?"

Gao Ge's heart suddenly skipped a beat.

He quickly walked over in three steps and then asked, "What's going on?"

"8633 actually sent two emergency codes in a row. No, it was three. 8633 issued three emergency codes in a short period of time." The controller said with a surprised look on his face.

When other people around heard this, they immediately cast doubtful glances.

"No, something's wrong." The controller thought there was a bug, so he right-clicked the mouse again and tried to refresh the screen.

Gao Ge's brows knitted into the character "Chuan".

See this.

He immediately stopped the controller and asked, "What emergency code did 8633 send? Is it 7700 again?"

Send three 7700 codes in a row.

Could it be that the crew of Flight 8633 could no longer hold on any longer, so they sent three 7700 calls in succession to the ground air traffic control for emergency help?

Although this situation is very rare, it does not happen.

Overseas, some flights encountered huge dangers. When they could not effectively contact the ground air traffic control, they would choose to send several emergency codes with the same meaning in succession, indicating that the situation they were encountering was very critical and needed immediate rescue.

But after hearing this, the controller immediately shook his head and said, "Yes and no."

Gao Ge couldn't help but scolded, "Yes, it means, no, it means no. How come you are still speaking so vaguely at this time?"

The controller was startled.

He quickly explained, "8633 hung three emergency codes with completely different meanings in a few seconds. First it hung 3, then 7600, and finally 7700."

Ok?
Gao Ge was confused.

Flight 8633 not only had three emergency codes in a row, but the meanings of the three emergency codes were completely different.

What kind of magic operation is this?
This is not how you play riddles!
What happened to the crew of flight 8633? Is it because of lack of oxygen in the brain?

Gao Ge hit his head hard.

He really wants to grow another head now, and then want to understand the purpose of sending three emergency codes 8633 in succession.

"Immediately report the latest situation to the General Administration, and then notify the Air Force and Sichuan Airlines. Don't be idle. Think about the purpose of sending three emergency codes 8633 in a row." Gao Ge said immediately.

It doesn't matter if you can't figure it out yourself.

Then mobilize everyone to think together.

What if someone’s brain waves match those of the flight crew of Flight 8633?
