cockpit.

Liang Dong turned around.

Looking at the bored Chen Bingbing, she said, "If you're really bored, why don't you connect to our wifi and play with your phone?"

Chen Bingbing was a little surprised, "Brother Liang, since when will there be a wifi signal on the plane? Doesn't it mean that electronic devices need to be turned off when the plane takes off?"

"Airplanes always have built-in wifi signals, otherwise how can we communicate with the ground in real time? It's just that the signal is relatively poor, and it must be in level flight to make the signal more stable." Liang Dong explained with a smile, "That is to say , the aircraft will automatically connect to the Internet above an altitude of 3000 meters, and will automatically shut down the network below that altitude."

"This is because when the altitude is lower than 3000 meters, the crew is most frequently in contact with the ground. If other electronic devices are connected to the network at this time, it will interfere with the connection between the crew and the ground."

"Oh." Chen Bingbing suddenly realized.

Then he asked, "Then when you have nothing to do, do you also play with your mobile phones?"

Liang Dong quickly denied, "How can you? The cockpit is full of monitoring equipment. If you don't want to lose your job, you'd better behave yourself."

Chen Bingbing clicked her tongue, "You guys are so strict, so I'd better not play, so as not to cause trouble to you guys."

"You're not a pilot. It's okay for you to play with your mobile phone. And you haven't watched the news. China Eastern Airlines has launched cabin wifi service as early as January 1th. Passengers taking China Eastern flights can also connect to wifi on the plane. , surfing the Internet.”

Starting from January 2018, 1.

If passengers choose to take China Eastern Airlines' dual-aisle wide-body aircraft (including Airbus A330/350 series, Boeing 777 and 787 series), they can use the air-ground interconnection function and experience surfing the Internet at an altitude of meters.

China Eastern Airlines’ air-ground interconnection function is currently in the free testing phase.

Only 10 passengers per flight can enjoy this feature.

Paid services will also be launched in the future.

It's just that the price is relatively high.

However, this is a trend and other airlines are expected to launch this service one after another.

Because people nowadays are too dependent on electronic products.

This dependence is not only reflected in life, but also in work.

Especially for office workers who travel for a long time, the few hours they spend on airplanes are also precious to them.

But what many people don’t know is that passenger aircraft have actually had air-ground interconnection functions a few years ago, but this function is not open to passengers and is limited to the cockpit.

After listening to Liang Dong's explanation, Chen Bingbing shook her head and rejected Liang Dong's kindness.

Although she is not a pilot, she is not an ordinary traveler either.

He didn't want to cause trouble to Lu Qingzhou and Liang Dong because of himself.

"Forget it, I am not an ordinary passenger on a passenger plane now, but a comrade fighting alongside you, so I should abide by the rules and regulations that you should abide by unconditionally."

Liang Dong saw this and did not continue to persuade.

Chen Bingbing asked curiously, "In the future, when taking a plane, won't I need to turn off electronic devices?!"

"Of course." Liang Dong explained, "Aircraft takeoff and landing are the most dangerous times during the entire flight. It is most taboo for other signals to interfere with the connection between the crew and the ground. Therefore, electronic devices must be turned off or the flight mode must be adjusted at this time."

"As for the flight process, it is not as strict as before."

"You can turn it on and read novels, play stand-alone games, or watch cached movies."

Chen Bingbing listened to Liang Dong's science popularization with great interest.

The beautiful eyes blinked.

Ah!
Another useless and strange knowledge (posture) knowledge (position) has been added.

"Then why were the previous requirements so strict? Some flights couldn't even be turned on during the flight." Chen Bingbing asked again. "This" Liang Dong opened his mouth.

Farke seems to have touched a blind spot in his own knowledge.

I just want to show off so that I can be a teacher to others.

Ok.

This outfit is too much.

So Liang Dong scratched the back of his head and said with some embarrassment, "There seem to be several explanations for why the requirements were strict in the past, but I can't remember the specific explanations. Captain Qingzhou, why don't you give me some advice? Popularize science!”

Lu Qingzhou then turned his head.

He opened his mouth and explained, "There are indeed several theories. One theory is that the signal of electronic equipment is not allowed on the aircraft because the electronic equipment moves too fast on the aircraft and puts too much pressure on the ground base station, so it is prohibited. .”

Chen Bingbing looked surprised, "This is too ridiculous. What does the plane flying so high have to do with the ground base station?"

"Even high-speed trains and high-speed trains can reach speeds of three to four hundred kilometers per hour, and there is no ban on turning on mobile phones on high-speed trains and high-speed trains." Liang Dong also commented.

Lu Qingzhou explained with a smile, "This statement is not nonsense. The FCC (Federal Communications Commission) ban on the use of mobile devices on airplanes was promulgated in 1991. At that time, 2G networks were not yet used. , all used mobile phones the size of bricks. Mobile phones used analog communication networks, and there were few base stations at that time, so when mobile phones looked for signals on airplanes, it might really lead to excessive pressure on ground base stations."

"As a 'beacon of humanity', the Yankees, especially in the 90s, were in a state of dominance. Therefore, many industry rules set by the Americans have become common industry rules around the world."

"So although this ban has lagged behind the times, it has still been in place for ten or twenty years."

Lu Qingzhou paused and then continued, "Another theory is that electronic devices, especially mobile phones, will frantically search for signals when they are on the plane, which will consume a lot of mobile phone power and also damage the battery. It had a big impact.”

"So flight attendants will advise passengers to turn off their phones or put them into airplane mode when taking a flight."

"Of course, now it all depends on the personal wishes of the passengers. The flight attendants only have a reminder duty."

"The third theory is what Brother Liang just said. The aircraft will frequently contact the ground when taking off and landing. If the communication between the crew and the ground is interfered by other signals, it may threaten the flight safety of the aircraft, so when the aircraft Passengers are required to turn off electronic devices during takeoff and landing.”

Lu Qingzhou's long speech.

Chen Bingbing was stunned for a moment.

She looked at Lu Qingzhou with an exaggerated look and said, "Sometimes I really want to open your head and see what your brain looks like. Why do you know all the weird knowledge points? Just like the aviation encyclopedia." It’s like a whole book.”

Lu Qingzhou quickly waved his hand, "Stop praising me. If you praise me again, I will take it seriously."

"Teacher Qingzhou, do I have a little question to ask you?" Chen Bingbing asked again like a curious baby.

Lu Qingzhou, who likes to be a teacher, nodded.

The voice was calm and magnetic and said, "Bingbing Children's Shoes, just ask."

"I just went to the bathroom"

"Ahem. I'm an aviation teacher, not a biology teacher. I can't answer physiological problems, especially those of girls." Lu Qingzhou quickly waved his hand and refused.

"Pfft." Liang Dong, who was drinking water, couldn't hold it back and spurted it out.

Chen Bingbing's little face instantly turned as red as red cloth. She glared at Lu Qingzhou and said angrily, "I hate it. I wouldn't be stupid enough to ask a straight man about physical problems."

Lu Qingzhou:
To express being offended.
