Almost every time we drive “I wonder why this is so?” On the planes where we encountered things that we questioned, the pilots Why do you always wear the same type of sunglasses? We can even think.

Or flight attendants Why do you always keep your hands tied behind your back? You’ve probably thought about it and wondered about it before. Let’s look at the answers to all these confusing questions.

Why do pilots always wear the same type of sunglasses?

The aviator model emerged in the early 20th century to meet a simple need of pilots. As the planes get higher headache The pilots’ vision was also very limited due to the thick glasses covered with fur around the edges.

Then it was decided to develop ideal glasses for pilots. The result is a lightweight product that covers most of the face. “pilot glasses” The models we mentioned are designed. This functional and lightweight design made the pilots very comfortable. Today it is still used as a fashion item and for its function.

Why are we asked to open the umbrellas during take-off and landing?

The basic principles of flight rules often have to do with safety. If we look at the statistics, we see that most aircraft accidents occur during landing and take-off. Therefore, the cabin crew is responsible for keeping the aircraft safe in case something goes wrong. see everywhere passengers should be evacuated accordingly.

In short, open the hatches, hosts and flight attendants Understand the situation faster in times of danger It allows them to act accordingly.

Okay, we understand the umbrellas, so why are the lights sometimes turned off during landing and take-off?

Also turn off the lights in the event of a possible accident One of the safety measures taken for British pilot Patrick Smith explains this situation as follows:

“The lights were turned off and passengers’ eyes were blinded. getting used to the dark is provided. A sudden cabin darkening that occurs for any reason can cause problems that can even lead to passenger blindness. “In addition, emergency lights are more visible in the dark.”

Let’s move on to another question: how much risk do we face if we are hit by an earthquake on an airplane?

The energy released during an earthquake spreads through waves called seismic waves. As these waves move through the air, gradually lose their density, that is, they lose much of their power when they reach a typical cruising altitude.

However, this still does not mean that we are not at risk. When earthquakes cause volcanic activity and flight at a low sailing level We may find ourselves in turbulence. In addition, if airport runways are damaged due to liquefaction in a major earthquake, we may face great danger during landing.

What are those white steam-like waves coming from airplane wings?

“Wingtip swirls” Rotating air movements at the tips of the wings cause the pressure in the air to decrease. When the pressure decreases, the air temperature also decreases. If the amount of water vapor in the air is sufficient, this cooling causes the water vapor to condense and form small water droplets that appear as white smoke.

However, in some cases this white smoke can also come from the engines. Caused by the combustion of aircraft engines exhaust gases condense and creates white smoke.

Why do flight attendants always keep their hands behind their backs as if they are hiding something?

Stewardesses; guaranteeing the safety of the flight, In addition to their duties as assisting passengers and making announcements, they have another job: counting.

Flight attendants responsible for counting boarding passengers usually place their hands behind their backs to accurately count passengers, which range from 100 to 600. a manual click counter applications. Of course, if the importance of appearance in aviation is added, such a view emerges.

Which seat should we sit in to suffer the least damage from a crashing plane?

In a study conducted as a simulation; on which chair, which one dolls in position take less damage It was checked and it turned out that the middle seats at the back of the plane were safer! The further away you were from the cockpit, the better your chances of survival.

Moreover, the result of this experiment was supported when accident reports from the past 35 years were examined. To the back of the plane, The intensity of the impact decreases and it feels less severe than the front one. This can of course vary from accident to accident and from aircraft to aircraft.

Since black boxes are often the only thing left intact after a plane crash, why aren’t airplanes made from the material of black boxes?

Black boxes are flight data recorders and are made of very durable materials. However, if airplanes were made from the materials of these black boxes, it would be impossible to fly them. Much more expensive it would be. In addition, the stretch factor of the wings is also important; the aluminum used in aircraft has high flexibility.

Moreover, titanium, the material of the black box, would also increase the loss of life because it could fly from such a height. A hard plane that hits the ground quickly It would be very difficult to get rid of it.

Bonus: there is one airport where only 24 pilots are allowed to land! Why?

Paro Airport in Bhutan is located between the Himalayan mountains. Besides being quite short at 2,000 meters in length, it is 2,235 meters above sea level. Good It does not allow errors.

In addition, there are many other factors, such as unpredictable wind. To cope with all these difficult circumstances, Bhutanese civil aviation authorities are the only ones in the world with the authority to land at Paro Habafield. consisting of 24 highly qualified pilots It limits it to a select group that undergoes rigorous training.
