Airplanes and Aviation Information

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

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

Why do pilots always wear the same type of sunglasses?

The pilot goggles model emerged in the early 1900s to meet a simple need of pilots. As the planes get higher suffering from headaches The pilots’ vision was also very limited due to the thick glasses covered with fur around the edges.

Afterwards, it was decided to develop ideal glasses for pilots. The result is a lightweight, covering most of the face. “pilot glasses” The models we mentioned were designed. This functional and lightweight design made the pilots very comfortable. Today, it continues to be used both as a fashion item and for its function.

Why are we asked to open the sunshades during takeoff and landing?

The basic principles of flight rules are often related to safety. When we look at the statistics, we can see that most plane accidents occur during landings and takeoffs. That’s why cabin crew are responsible for keeping the plane safe in case something goes wrong. seeing everywhere passengers should be evacuated accordingly.

In short, having the blinds open, hosts and stewardesses Understand the situation faster in times of danger It enables them to act accordingly.

Okay, we understand the sunshades, so why are the lights sometimes turned off during landing and takeoff?

Turning off the lights too in case of a possible accident One of the security 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 suddenly darkened cabin that occurs for any reason can cause problems that can even lead to blindness of passengers. “In addition, emergency lights can be seen more clearly in the dark.”

Let’s come to another question: How much risk would we be if we were caught in an earthquake on a plane?

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

However, this still does not mean that we are not at risk. If earthquakes cause volcanic activity and flight at a low cruising level We may get caught in turbulence. Additionally, 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 out of airplane wings?

“Wingtip vortices” Rotational 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 tiny water droplets that appear as white smoke.

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

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

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

Flight attendants who are 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 uses. Of course, when the importance of appearance in aviation is added, such a view emerges.

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

In a study carried out as a simulation; in which seat, which puppets sitting 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 you were from the cockpit, the better your chances of survival.

In addition, the result of this experiment was supported when accident reports of the last 35 years were examined. Towards the back of the plane, The intensity of the impact decreases and it feels less severe than the front ones. Of course, this may vary from accident to accident and plane to plane.

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

Black boxes are flight data recorders and are made from very durable materials. However, if airplanes were made from the materials of these black boxes, it would be impossible to fly them. much more costly it would be. Moreover, the wing stretching factor is also important; the aluminum used in aircraft has high flexibility.

In addition, 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 hitting the ground fast 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 among the Himalayan mountains. Besides being quite short with a length of 2000 meters, it is 2,235 meters above sea level. Well It does not allow mistakes.

Besides these, there are many other factors such as unpredictable winds. To overcome all these difficult conditions, Bhutanese Civil Aviation authorities are the only ones in the world who have the authority to land at Paro Habafield. consisting of 24 highly qualified pilots It limits it to a select group that undergoes rigorous training.
