Dmitry, the author of the channel “the Pilot” on “Yandex. Zen” working in civil aviation. On his page he talks about the cases that happened to him during the flight, shares the facts about the work and answer questions, which certainly excited every passenger aircraft.
We AdMe.ru read the posts by Dmitry and with his permission I want to share some of them with you.
1. As the pilot goes to the toilet, if you want to steer the plane?
For almost the entire flight (except takeoff and landing) airplane control is in automatic mode, and the pilot can go to the bathroom. However, for assistance, please call the stewardess. She needs to go into the cabin and make the company the second pilot. According to safety regulations, it is impossible to leave one person near him always needs to be someone.
2. Is it possible to change seats on the plane?
Yes, but only when it does not compromise the safety of the flight:
- fragile girl is not allowed to sit by the window near the emergency exit, because in an emergency it is unlikely to be able to open it;
- oxygen masks for children are not over each seat.
There is also the theory that the insurance company can deny you payment if you get injured, sitting out of place. But that’s not true.
3. Why threat a meeting of the aircraft and the birds?
When meeting with a 3-pound bird at 300 km/h the plane is struck in the equal to drop 100-pound barbells from 20-meter height. Such a force can penetrate the Windows and the fuselage. The engine of the plane, like a big vacuum cleaner, sucking up everything that is in front of him. If a bird gets in his range, it sucks in, further accelerating. Damaged the blades, and the engine fails.
Last year in Russia recorded more than 7,000 collisions of aircraft with birds. Usually affect only one engine, but in the case of the Airbus A321 of order out of both, so the commander of the ship decided to carry out an emergency landing in a cornfield.
4. Why during takeoff and landing, the armrests should be lowered?
Takeoff and landing — the most difficult phase of flight, and need to protect. The armrest is a good place to stand and, if it is omitted, in an emergency, the passenger will quickly leave his seat. But not all airlines this requirement is mandatory.
Also under heavy braking or severe turbulence armrest may fall and injure the passenger.
5. Why tomato juice tastes better on the plane than on the ground?
Because of the constant noise in the plane we have blunted receptors. Tomato juice contains large amounts of glutamic acid, the taste of which is stronger compared with others (sweet, bitter and sour). Because of this, at an altitude of 10 km the tomato juice is so delicious, more precisely, it is the same as before, but other drinks do not cause us such satisfaction. For the same reasons we don’t like plane food.
The remarkable fact is that tomato juice is only among the Russian-speaking population. European and American citizens only on the 3rd place after Apple and orange.
6. Why passengers are in the plane only on the left side?
The entrance is on the right side is used to service the airport loading Luggage and food. And in the left side of the landing and receiving of passengers. These rules apply in almost all airports in the world, to one algorithm that they can serve different types of aircraft.
Originally this standard was not, but after 1940 it was decided that the passengers will use only the entrance on the left side.
7. Why did all the pilots wore silk scarves?
During the development of the aircraft was not radar, and the pilot for detecting and tracking the enemy was actively turning his head. Because of this hard gate leather jacket strongly rubbed the skin, often to the blood. Scarf has solved this problem, but he also had to confront the powerful currents of the wind to be soft and easy, and these properties had only one material is silk. A white scarf was because originally the pilots cut them out of aircraft parachutes that color, and later in the manufacture of tradition did not break (but that’s just theory, the truth is no one knows).
8. Why before you could smoke on the plane, and now it is impossible?
Before you could smoke right in the airplane seat, but in 1986, in Soviet Union it was forbidden to do on flights lasting less than 3 hours. Although people still smoked in the toilet, and during long flights and in their places. Every year began to appear more and more complaints, especially from passengers with young children, so in 2002 Aeroflot has banned Smoking on all flights. It was followed by other airlines.
In the United States a similar rule was introduced in 1988 but it was effective immediately for all kinds of flights.
9. Can a flight attendant to land the plane, if the pilots lose consciousness?
In the flying school flight attendants no one learns to fly a plane. But with professional help and under certain conditions, it is likely that the stewardess will put the aircraft:
- if she can contact the Manager;
- if the weather will present no surprises (for example, in a crosswind hard landing even some pilots);
- if the person on the other end properly coordinate its actions.
Similarly, land can not only a stewardess and a passenger (but of course an inexperienced person to do very dangerous).
10. Why you should not applaud after landing?
Landing ends, not when the landing gear touches the runway, and only when it announces the aircraft commander. But he will not hear the applause, because the doors between the saloon and the cockpit armored, and almost never miss any sounds. All the popping I hear only flight attendants and passengers.
11. Why planes use headphones with 2 inputs?
Previously, there was disposable headphones when boarding, passengers are handed out reusable, and when you exit the plane they were taken. But some people took the device with him, so it was made 2 plug (for left and right ear). On the other hand, this was done for reliability: if fail one channel, it always was different, and without music no one remained.
Then began to use disposable earphones, but to change the connector, no one was going, as it is a long and laborious work. Although some aircraft now found the familiar entrance.
12. Why on the morning flight to fly better than in the evening?
This is for 3 reasons:
- According to statistics, the morning flights are delayed less than dining or evening. This is because the main stream of flight corresponds to the day. And the more people, the higher the probability of delay. The optimal departure time — 6-7 a.m., not later. Night of too few passengers, but flying at this time less comfortable for the body.
- Since most people prefer daytime flights, and the queue will be longer during the day.
- As a rule, the price of the ticket for the morning flight below.
13. Why in the cockpit is the axe?
The axe is in the back of the chair the captain of the ship and covered with a special material which does not pass current. It is designed for cutting holes or cutting the door in case of emergency. Most likely, you have seen special marks on the aircraft to strike with an ax, but did not pay attention to it.
14. How many minutes is enough oxygen in an oxygen mask?
Most people will assume that every passenger seat is a cylinder with oxygen, which, when the emergency situation will begin to enter the mask.
But it’s not. Oxygen is released by combustion of a special chemical mixture. This process is activated when the person is pulling the mask. On a normal passenger aircraft of its action will last for 12 to 20 minutes. This time the pilots is enough to reduce the ship to a “normal” height.
15. Why turn the lights out on takeoff and landing?
This is due to security measures. If you have an emergency and need to evacuate, quickly open the emergency hatches, but since the street is dark, our eyes after the bright light in the cabin can not see anything, and to leave the plane will be difficult.
But if the light is off, we have already pre-accustomed to the darkness, allowing to clearly see the silhouettes of the objects and to react quickly to different situations. This rule only applies for takeoff and landing because they are the most dangerous moments of the flight.
16. Why is aircraft forbidden to fly over the Himalayas?
The average height of the Himalayas is 6 km and the flight is 10 km away. in the event of an emergency such as depressurization of the cabin, the pilots will have 20 minutes (the duration of an oxygen mask) to decline to 3 km above sea level, so that people could breathe. But over the Himalayas, the aircraft will have nowhere to fall, so flights are prohibited due to safety requirements.
The second reason is the constant turbulence. Over the mountains are strong winds. To make the flights comfortable, all planes overfly their South Indian side (except for excursion ships — they fly over the mountains is possible, but special routes).
17. Why pilots can’t wear sunglasses and a beard?
Almost all sunglasses — polarized, that is, not missing any glare and reflections. But the fact that the light from LED monitors computer systems of the aircraft is visible only under certain angle. To see the readings on the screen, the pilot will need to twist the head. But the cabin is a single monitor, and about 20. And if a pilot is something you will not notice can be a tragedy.
If the glass is just tinted, not polarized, it does not interfere with viewing angle. But as flight safety is paramount, some airlines prohibit any glasses during flights.
And the beard of the pilot cannot be worn due to the fact that if he had to wear the oxygen mask will fit the face tightly, and it has the risk to pass out from oxygen starvation.
18. In some places most likely to survive a plane crash?
The researchers conducted the experiment. At each passenger seat they put on the dummy, have installed special sensors and video cameras, and simulated accident at a speed of 230 km/h Boeing 727 “fell” on the surface of the lake, drove a hundred meters and then broke into several pieces. The most dangerous place turned out to be the nose of the aircraft — seats of the business class. The main power of the impact came in the area, resulting fissure, separating the nose of the aircraft. And the minimum “damage” received the mannequins sitting in the tail. At the same accident in the life of the passengers in this part of the ship probably would have survived. But the blow could come at any part of the aircraft, so it is impossible to conclude, based only on this experiment.
But statistically, were taken and analyzed all crash of the passenger aircraft in which people survived. In the field of business-class survival rate was 50 %, in the Central part of the salon — 55 %, in the rear — 70 %. So do not worry much if the next time you will place the toilet at the end of the plane.
19. Whether to drop the plane due to turbulence?
Turbulence can be caused by the following factors:
- turbulence from the wings the next coming of the aircraft;
- the meeting of the different temperature streams of air masses;
- uneven heating of air near the ground.
Dangerous is turbulence in storm clouds, so pilots try to fly around their side. It can also happen in clear sky, this phenomenon is called “turbulence on a clear day”.
But in the history of aviation because of this shaking a plane crash. And then the role played by the human factor: the turbulence was caused by the front of the liner. So when the plane starts to shake, you need to buckle up and not panic — it is safe.
What other questions would you ask the pilot?
