"Captain, what did you say?" The co-pilot had long been distracted by the arc on the windshield, and he didn't hear clearly for a while, so he stretched his neck in a daze and listened to the stern words.

Yan Zhen didn't answer, and hurriedly pressed the launch button: "Area control, blue sky 834X, how many do you listen to me now?" ”

"Listen to a few" is a technical term in civil aviation, which is a standard for judging the quality of radio signals. It is represented by a number from one to five. If you can hear the other person's voice clearly and loudly, that is, the signal quality is very good, it means that the radio signal quality is five. The signal quality is almost four, and then three.

Generally speaking, a radio signal quality below three indicates that the signal quality is not good.

In real flights, not only the pilot will measure the quality of the radio signal, but also the control will also measure the quality of the radio signal. Whoever wants to test the quality of a radio signal asks "How many signals do you listen to me?" in the frequency. ”

Depending on the quality of the signal, the listener will respond to any number from one to five, which is a general process of radio signal inspection.

Ask others how many signals they listen to, one function must be to check the quality of the radio signal, and the other is to check the gesture of radio failure.

Radio communication in civil aviation is disciplined, not just say what you want to say, which will appear very unprofessional. For example, when verifying that the radio is failing......

The chance of a radio failure is small, but not impossible. There are usually three types of radio signals, transmitter failure, receiver failure, or both.

The transmitter failure is what the pilot says, and the controller can't hear it, but the controller can hear the instructions given by the controller.

The receiver malfunction is the opposite, the pilot speaks, the controller can hear, but the controller speaks, the pilot cannot hear.

Both the transmitter and receiver are faulty, which is the so-called two-way loss of contact, and no one can hear anyone.

In general, how are radio failures discovered? The most common is that no one speaks for a long time on the radio frequency. If it is on some routes with few planes, or in the early hours of the morning or in the middle of the night, it is normal, but if it was very lively in the radio frequency some time ago, and it didn't take long for it to be completely silent, wouldn't it be strange?

Just now, the radio frequencies were still as lively as the vegetable market, and the opportunities to see the stitches were very few, why is it so quiet now, it's really weird.

If the pilot can't hear the radio frequencies for a long time, he will ask, "How many signals do you listen to me?" ”

At this time, the controller will answer that the signal is several, and the pilot does not really want to determine the radio signal, but just let the controller make a sound and let him hear it.

The reason why I beat around the bush is because I want to be more subtle, and I can't just say: "Control, can you hear me?" Speak up to you? ”

Believe it or not, the control will report it to you on the spot.

Yan Zhen couldn't hear the sound in the radio frequency for a long time, and he was suspicious, so he wanted to verify it, so he asked the control to listen to the signal, and looked forward to the control reply.

But after waiting for a while, there was no response from the radio frequency. Yan Zhen didn't give up, and tried to call a few times, but in the end, he didn't care about it, and asked directly: "Control, can you hear it?" ”

It's just like this, I asked a few questions in a row, and I was stunned that there was no squeak on the control side. Not only that, but even if there is no sound from the control, there is no sound from other aircraft, which is very strange.

"Captain, I'll try!" The co-pilot saw that the captain Yan Zhen shouted for a long time without an echo, and his heart tightened, so he was ready to try the transmitter from his side.

The VHF antenna used by the captain and co-pilot is not one, and it is not possible to use his transmitter.

"Control, Blue Sky 834X, how many do you listen to my signal...... Control, can you hear me? The more the co-pilot shouted, the more anxious he became, he really didn't want to blame the radio failure.

If the radio fails, he has to hang an emergency code, and he doesn't want to get involved in it.

The co-pilot shouted urgently, and suddenly the headphones sounded intermittently, like an electric microphone, a vague sound, like the sound of control, and like the sound of other aircraft, the background noise was too loud, and the co-pilot and Yan Zhen couldn't hear it clearly.

Even if you don't hear what it is, at least some response is a good thing. A hint of joy flashed in the co-pilot's eyes, and he shouted urgently.

At this moment, a dazzling light burst out outside the cockpit, as if a flashbang exploded in front of the windshield, and the entire cockpit was wrapped in shining light, Yan Zhen and the co-pilot even lost their eyesight in an instant, commonly known as "bright blind"!

Lightning! It's lightning! The light of lightning is so dazzling!

Obviously they have kept enough distance, how can it seem that lightning is close at hand?

"Don't ......" Yan Zhen was puzzled in his heart, and a whistling sound that seemed to puncture the eardrum suddenly erupted from the earphones. Yan Zhen and the co-pilot were like electric shocks, they couldn't stand the sound of such a high pitch, like a thousand steel needles drilling into their heads, and their temples were about to bulge. As if avoiding the plague god, the two threw off their headphones and picked up their ears in unison.

"What's wrong with this radio, if my eardrum is broken, who will I talk to!" The co-pilot plucked out his ears, but his mouth kept complaining.

The whistling voice just now was extremely high-pitched, sharp to the sky, sharper than all the female voices he had ever seen in his life, and I am afraid that only the sound of fingernails scraping the blackboard could be compared.

Just hearing this sound, goosebumps all over his body rose, which was an uncomfortable feeling from his soul genes.

"What's wrong with the radio?" Yan Zhen is also picking out his ears, even if it has slowed down until now, his ears are still crispy and numb, and at this moment there is still the buzzing of small bees in his braincase.

The co-pilot responded: "Isn't this a radio bomb!" ”

"Captain, I'll try calling them again." The co-pilot picked up the headphones again, listened to them in his ear, and after making sure there was no whistling, he put them back on.

"Control, Blue Sky 834X, can you hear me?" The co-pilot continued his calling path. It's just that after the whistling sound just now, there is now a constant background noise in the headphones.

Although the noise was also very strong just now, I could barely distinguish some voices, but now there is no sound at all, just some background noise, and there is no useful information at all.

The co-pilot shouted for a long time, but there was still no answer, so he stopped shouting and turned his head to look at the captain Yan Zhen: "Captain, let's ......"

Yan Zhen didn't speak, but made a silent gesture, sniffed inexplicably, and frowned: "Did you smell any strange smell?" ”

"What?" The co-pilot was stunned, Yan Zhen's rhythm changed too fast, and his brain really didn't keep up.

Yan Zhen sniffed a few more times, and his brows tightened: "Strange smell?" Don't you hear it? ”

"Strange smell?" This time, the co-pilot understood it, and sniffed twice with Yan Zhen's appearance, and a trace of confusion gradually appeared on his face: "It's a strange smell...... This is...... The smell of ozone? ”

During a thunderstorm, some of the oxygen is ionized into ozone, which is a gas with a special odor. Now they seem to be very close to the thunderstorm clouds, and it makes sense that there is some ozone nearby. If you pass through an area with ozone, the engine bleed air will inhale the ozone together, and the air conditioning system will be filled with ozone, which will be dispersed throughout the cabin, and it is not unreasonable to smell some strange smells.

The reason why the co-pilot had this idea was that he had encountered it several times before when he was on a flight during a thunderstorm. It's natural to think of ozone.

However, when you look closely, the smell you smell now seems to be different from the ozone smell you smelled before.

Ozone is a special gas with a fishy smell, and its odor characteristics are still relatively obvious and easy to distinguish. It's just that the smell doesn't seem to look like a fishy smell! Why does it feel a little burnt?

Burnt taste! The co-pilot's brain exploded, and he was reluctant to say what he thought. Smelling burnt on a plane is not a good sign!

Yan Zhen saw that the co-pilot's face was not good-looking, and said bluntly: "Isn't it a bit like burnt paste?" ”

I'll go! The co-pilot's taboo idea was directly broken by the captain, so he had to nod stubbornly: "It's a bit like!" Captain, did you say someone was smoking in the toilet! ”

The co-pilot is still a little self-defeating.

"Are you kidding? How many people can take lighters through security now? Besides, didn't I just ask the cabin crew to check the toilet? How can there be people in the toilet now? "Yan Zhen cut the railway.

With the current strength of civil aviation security check, the probability of being able to pass the security check with a lighter is basically equal to zero, and the lighter is the focus of the security check project, and it is difficult to pass the customs in confusion.

In addition, just now he expected that there would be violent turbulence, and deliberately asked the cabin crew to quickly patrol the cabin, which specifically explained that for a period of time, he would wait for the bumpy area before opening the toilet.

It's uncertain whether there will be time to patrol the cabin, but there will definitely be time to make sure the toilet is empty. Either reason is enough to rule out the possibility that someone smokes in the toilet.

Taking 10,000 steps back, he can be regarded as an old smoker, and the smell of burnt paste and smoke can still be distinguished.

This is clearly not the smell of smoke, but the smell of burnt wires.

Once this thought came to mind, it lingered like a nightmare, and the more Yan Zhen and the co-pilot thought about it, the more they felt that it was possible, and the little hearts of the two of them beat faster and faster.

The worst thing is that there is no fire detection, the two of them can't figure out what is wrong, this kind of unclear situation is the most terrifying, no one knows what will happen in the next second.

"Captain, what shall we say?" The co-pilot couldn't make up his mind at this time, so he could only ask the captain's opinion. At this time, the role of the captain is reflected, and under normal times, the co-pilot can still take most of the time, and the role of the captain may not be fully reflected at this time. However, once there is any special situation, at this time, the backbone is the captain, and the captain is the Dinghai Shenpin, and it is the captain who makes the final decision.

"In any case, we have to wait until we pass through this cloud area, and now the top priority is to establish communication, otherwise there is nowhere to talk about even if we want to divert and land." Yan Zhen said.

Now there are thunderstorm clouds on the left and right of the plane, and the cumulus clouds below are extremely thick, and at first glance, the ice accumulation situation is very serious, and it is impossible to go down for the time being. Now, no matter what the situation is, you must first pass through this cumulus cloud area, wait for the weather to be affected, and then depending on the situation, you should make an alternate landing and an alternate landing, and continue to fly forward if you should continue to fly forward.

Therefore, the first problem is to establish communication, otherwise if you want to divert or something, you must communicate with the control. The whole airspace is not opened by your own home, so you can't go wherever you want. And if you really want to make an alternate landing, you also need to control to help contact, and the plane can't just choose an airport to approach it, which is too lawless.

Yan Zhen pinched his nose from time to time, and a thenar muscle rubbed back and forth on his chin, revealing a hint of anxiety. Radio failure doesn't make him so anxious, but it's different in the current environment, when radio communication is most needed.

"Try HF!" Yan Zhen said suddenly.

"High ...... High-frequency communications? The co-pilot's face fell, and his hands were spread: "Captain, I have never used high-frequency communication since I started flying!" ”

Now not only in China, but also in civil aviation all over the world are basically using VHF communication, and high-frequency communication will only be used in certain specific areas, such as transoceanic flights.

Yan Zhen and the co-pilot have never flown across the ocean, let alone the co-pilot, even Yan Zhen has never used high-frequency communication.

"It's like I've used it." Yan Zhen fiddled with the communication panel and changed the VHF button to HF, at this time the communication panel can tune the high-frequency frequency, but now there is another problem, Yan Zhen glared: "What about the high-frequency frequency?" ”

The co-pilot was stunned, this high-frequency communication has not been used for a long time, where does he remember!

"What's the matter with you, the inquiry when you turned to the first co-pilot didn't ask about the radio failure? Didn't ask how to use high frequencies? Yan Zhen did not hesitate to throw the big black cauldron to the co-pilot.

Good fellow, it's up to me!

The co-pilot said innocently: "Captain, then your inquiry to the captain is much stricter than ours, so why don't you ......?"

Yan Zhen was very displeased: "How long have I hired the captain, where do I still remember, I don't need it for a long time." How long have you been spinning a pair, didn't you still say that you haven't flown a few shifts when you flew together yesterday? How long has it been, and you've forgotten? Okay! ”

Yan Zhen's last sentence has already involved personal attacks!

The co-pilot was sprayed by Yan Zhen and almost doubted his life, although he was very cowardly, but the reason was that he didn't study hard, and he hated less when the book was used!

Yan Zhen couldn't count on the co-pilot, and in the end he had to rely on himself. He tried to recall, seemed to have a slight thread, and patted the co-pilot on the shoulder: "Go, go get the high-altitude map." ”

Yan Zhen thought for a while, and finally remembered something, he remembered that the high-frequency frequency seemed to be recorded on the high-altitude map, and each area had its own high-frequency frequency, which seemed to be presented in a table form.

"Blue Sky 834X, does the weather still affect you over there? Is it possible to turn right to head 250? "The control looks at the blue sky 834X has reached and maintained an altitude of 8100 meters. In order to avoid the weather, other aircraft applied for a heading, which happened to have some conflicts with the Blue Sky 834X. So the control tried to discuss with the blue sky 843X, if the blue sky 834X can turn around and give up an airspace, then other aircraft can also avoid dangerous weather.

Of course, if the blue sky 834X is inconvenient to change course, the control will not be forced, and it will only find another way.

"Blue Sky 834X, do you think it's convenient to turn right?" The control saw that the blue sky 834X did not respond, and asked again, and waited for a few seconds, but there was no answer at all.

At this time, the communication of other planes began to sound in the frequency again, and the radio frequency, which had just calmed down for a moment, returned to the lively and abnormal situation just now.

The control is tired of dealing with the applications of other aircraft, and the matter of the blue sky 834X is forgotten, and the default is that the blue sky 834X cannot turn course.

After disposing of the applications of other aircraft for a while, seeing that the blue sky 834X was about to reach the handover point, the control was ready to let the blue sky 834X turn the frequency in advance, which was the command: "Blue sky 834X, contact the area to adjust the control 133.25, goodbye." ”

Waited for a while, but there was no answer. At this time, the control didn't feel anything, after all, it was normal for the crew to occasionally not pay attention, and now the radio frequency was very busy, and it was not a big deal for the crew to miss it once. Or maybe the crew was concentrating on the flight and didn't notice the call on the radio frequency.

Not to mention that there is a mistake in the high-pressure environment of thunderstorms, even during normal flight, sometimes the crew chats too deeply and misses a piece of radio communication.

However, it's normal to not respond once, so what about two, three times? If there is no response on two or three occasions, it must be taken seriously.

That's right, the Blue Sky 834X was called three times and still didn't respond.

"Blue Sky 834X, please answer when you hear it, answer it when you hear it!" The control called several times in a row but still didn't answer, and at this time the control began to be a little anxious.

At this time, the control not only has to deal with the application of other aircraft to fly around, but also pays attention to the situation that the blue sky 834X does not respond, which is a huge pressure on the control.

I called several times, and the blue sky 834X still didn't respond, and at this time, the control faintly felt that something was wrong. However, fortunately, he can still see the blue sky 834X on the radar, and the blue sky 834X does not have an emergency code, which is the only place where the control is gratified. He doesn't want to have an emergency code in his jurisdiction.

It's not that he doesn't have the ability to deal with emergencies, it's that he doesn't want to! Let a sleeping dog lie.

"China Airlines 4789, apply for heading 120 due to weather conditions." At this time, another China Airlines plane applied for a roundabout.

The controller immediately replied: "Heading 120 agreed." ”

Immediately afterwards, the control changed the conversation and broadcast a report: "Now the whole channel is silent for a minute, except for emergencies, don't call!" ”

Now there are many people in the radio frequency, and the blue sky 834X crew did not hear their own call in the noisy communication, so they simply let the radio be silent for a short time, if they can't call, they have to change their ways.

"Blue Sky 834X, please answer when you hear it, Blue Sky 834X, please answer when you hear it!" The controller called twice in a row, but there was still no answer.

The control heart was beating wildly, and he immediately changed to the emergency frequency and called: "Blue Sky 834X, District Control 121.5 called, please answer when you hear it." ”

The frequency of 121.5 is the international emergency frequency, and all aircraft will listen to this frequency under normal circumstances. Normally, if an aircraft cannot be called, the control will try to call again through the emergency frequency.

But it backfired, even in the emergency frequency, it still can't shout blue sky 834X!

It's really a bit panicked at this time, what is this? I can't call it, and I don't have an emergency code, what is the situation now, he is really black-eyed.

This feeling of not knowing anything is the most uncomfortable!

"Could it be that the thunderstorm affected the radio communication signal?" The control is beating the drum in his heart, but he also has some guesses. Thunderstorms do affect the quality of radio communication, but now communication equipment is not what it used to be, and it is not just a thunderstorm that can isolate radio signals.

Unless...... Unless it's lightning that breaks the antenna on the plane!

Now the blue sky834X has not hung the emergency code of radio failure, it is very likely that the crew is still trying to get in touch with other means, if you wait for a while, all means have been tried or can not establish communication, then the only way to hang the emergency code is to go.

Although there is some speculation, he can't wait for the blue sky 834X to hang the emergency code of the radio failure before taking action, he must try again. Now the normal communication methods have been tried, and I can only try some partial methods.

The control found the location of the Blue Sky 834X from the radar, and found an aircraft in the closest place to the Blue Sky 834X and the closest altitude, which was the Xingfei 5777 that had a conflict with the Blue Sky 834X before.

"Xingfei 5777, you can help me tell the blue sky 834X, just say that the control is calling him." The regulator commanded.

Take 10,000 steps back, if the thunderstorm really affects the quality of communication, and the control is not connected with the blue sky 834X, then it is more feasible to let other aircraft convey it on behalf of you at this time.

Xingfei 5777 paused, and then said: "Blue Sky 834X, the control is calling you, please answer when you hear it." ”

In a word, I was stunned that I didn't even make a splash, and the blue sky 834X was like a pool of stagnant water, and there was no reaction at all.

"Blue Sky 834X, the control is calling you, please answer when you hear it!" Xingfei 5777 tried again.

In the end, Xingfei 5777 had to give up: "It seems that you can't shout!" ”

"China Airlines 4785, Dongfang 6584, Longyue 9888, you can help shout!" I don't care about the control at this time, and I talked to all the planes near the blue sky 834X, and asked them to try to shout the blue sky 834X.

All of a sudden, the radio frequency was full of voices calling blue sky 834X, and the control was also a dead horse as a live horse doctor, but the result was very realistic, but it couldn't be shouted.

Just when the frequency was shouting hotly, a weak voice interjected: "Control, just now I seemed to hear Blue Sky 834X calling you." ”

As soon as this voice came out, the voices of the calls one after another Blue Sky 834X immediately quieted down, and the control was even more energetic: "When?" What did you say? ”

"Just a few minutes ago, he seemed to be calling you, too, several times! The voice was too vague, to be honest, I wasn't quite sure if it was Blue Sky 834X, and I didn't hear his call sign very clearly. However, there is a high probability that it is Blue Sky 834X. The crew said.

"And after that? Did you hear it afterward? The regulator said anxiously.

At this time, the crew was more certain: "I didn't hear it later, so I shouted for a while, and then it was gone!" ”

"Oh, thank you then!" The controller thanked the crew for the information. From this point of view, the call heard by that crew should be Blue Sky 834X.

If the information provided by the unit just now is not wrong, the control has already had some calculations in his mind at this time.

Blue Sky 834X has been calling themselves, indicating that the crew may have found a communication problem, and the reason why they try to call themselves is that they can't hear the sound on the radio, so they suspect that the radio is invalid.

Since the sound of the radio cannot be heard for a long time, it means that the receiver of the blue sky 834X is very likely to have a problem.

At the same time, just now Blue Sky 834X has been trying to contact himself, but he didn't hear it here, and other planes didn't hear it, only one plane vaguely heard it, and then there was no news. It shows that there are also some problems with the transmitter of the blue sky 834X.

If there is a problem with the receiver, there is a high probability that the transmitter will also have a problem, and this is not the most difficult two-way communication failure?

When I think about this, I feel that my head is as big as a fight! After thinking about it for a while, the controller decided to report the matter to another talk!

......

At this time, in the cockpit, Yan Zhen turned on the map light and carefully looked for the location of the high-frequency frequency.

Sure enough, he remembered it well, the high-frequency frequency was on the high-altitude map, he carefully identified it, and suddenly asked, "What time is it?" ”

"Huh? What time is it? Oooh! Quarter past five! The co-pilot replied.

"Okay, let's try these two. One works 24 hours a day, and the other works from 8 a.m. to 8 p.m. Yan Zhen pointed out the high-frequency frequency on the high-altitude map to the co-pilot, and after the co-pilot understood, he directly threw the high-altitude map to the co-pilot.

The plane has been in a state of turbulence, he should pay attention to the state of the plane, a little to get close to the high-altitude map to find the high-frequency frequency, the high-altitude map on the symbols and numbers are dense, in the case of shaking, look at it for a little longer and feel dizzy.

Since I found the high-frequency frequency, I simply handed it over to the co-pilot to do it and rested a little by myself.

High frequencies are used in the same way as VHF, but the frequency format is different. Almost all VHF frequencies start with one, such as 121.5, 133.55, and so on. And the high-frequency frequency does not have this statement, just now Yan Zhen took a cursory glance, and the high frequency in this area seems to start with six.

The co-pilot switched his second VHF to high-frequency mode, and the VHF on the captain's side remained unchanged, still listening to the radio frequency just now, what if the communication suddenly resumed?

The co-pilot adjusted the high-frequency frequency, adjusted the transmitter, and began to call: "Blue Sky 834X call, can you hear it?" ”

Yan Zhen actually opened the second high-frequency receiving button, and if the second high-frequency responded, he could also hear it.

It's just that the co-pilot called for a long time, just like a mud cow entering the sea, without a sound.

"Change one, try another one!" Yan Zhen instructed the co-pilot to try another high-frequency frequency.

The co-pilot sighed and adjusted the frequency again against the high-altitude map. It was still the same call, both of them pricked up their ears and listened, but there was still no answer.

"What's going on! What's going on! You kid can't adjust the wrong frequency! Yan Zhen was about to go crazy, pointing to the high-altitude map and shouting: "Give it to me!" ”

The co-pilot was unwilling to return the aerial map to Yan Zhen, and he was very dissatisfied with Yan Zhen's suspicion that he had adjusted the wrong frequency. Even if he is not a top-notch co-pilot, he will not adjust the wrong frequency, he is numeracy-sensitive!

Yan Zhencai didn't care about the co-pilot's complaints, but compared the frequency with the high-altitude map and found that there was indeed no problem. He didn't give up, he turned another frequency back and gave it a try, and the result was still the same.

"No, what's going on now? Is our high-frequency antenna also broken? What kind of luck is this? Or are the people in the command room sleeping and not hearing? Yan Zhen irritably threw the aerial map onto the center console, and his mind was about to explode.

He wiped his face with both hands, calmed down a little, and adjusted his mentality. Half a minute later, Yan Zhen eased up a bit, licked his dry lips, tried to squeeze out a smile that was more ugly than crying, and said to the co-pilot: "It's okay, don't worry!" We're not there yet, VHF doesn't work, high frequency doesn't work, we still have satellite phones, we still have ACARS, as long as we contact the home, let the family communicate on behalf of the family. ”

A satellite phone is a satellite communication system based on a satellite communication system to transmit information, that is, a satellite relay intercom, which can fill the problem of no mobile phone signal at high altitude.

Nowadays, almost every plane is equipped with a satellite phone, and now the donkey has poor skills, so he can only use the satellite phone to contact the company's operation control department first, and then convey his intention to the control department through the operation control department. In other words, what instructions do the control departments pass on to themselves through the company's operation control department?

This kind of contact method using the company's operation control department as an intermediary is very troublesome, and its efficiency is not at all comparable to direct communication by radio. But now that I have no choice but to choose this stupid way.

The so-called ACARS communication is to send text information to the company's operation control department through the ACARS system, and communicate through text information.

Due to the word limit in ACARS's text communication, you can't type too many words at a time, and you can only enter letters, not Chinese characters, which undoubtedly adds to the difficulty. Not only is it inefficient, but it is also quite difficult, even more frustrating than the method of satellite phones, so this can only be used as a last resort.

During this period, Yan Zhen could always smell the smell of burning, which was a lingering haze for him. He wanted to establish a connection as soon as possible and then land as soon as possible.

Now that he was actually not far from his destination N City, if he could establish a communication, as long as the burnt smell did not worsen, or no obvious special circumstances were found, he still decided to continue flying to N City. Because in fact, the distance between flying to the alternate landing site and flying to the destination airport is not long, and the supporting facilities in N city are better.

"The satellite phone will be used, you look for the company's AOC number." Yan Zhen said to the co-pilot.

The way to dial the satellite phone of this aircraft is through the CDU dial, the company has long saved the AOC number input in the CDU, as long as the pilot calls it out, press the dial button, it is relatively easy to operate.

"Yes, yes!" The co-pilot knows how to call up the AOC number, so hurry up and operate the CDU.

Yan Zhen picked up a wet towel to wipe his face, a series of things just now made him a little tired, and he needed to wake up.

Just as Yan Zhen was wiping his face, he suddenly heard the co-pilot sigh softly, and he wiped his face while asking, "What's wrong?" ”

Suddenly, he felt that his arm was pushed, and when he put down the towel, he saw the co-pilot pointing at the CDU, and his face turned black.

"Captain, the CDU is automatically turned off!"
