JAKARTA – Airplane has some interesting facts that many people may not know about. This means of transport is often an option if you want to travel far.
In addition to accelerating the distance from one place to another, airplanes are often chosen because they are the safest means of transport compared to other types of transport.
For those who frequently use or wish to use this means of transportation, it is important to know a number of unique facts about airplanes in advance.
Reported by the Youtube channel iNews Variety Show, Saturday (09/24/2022), here is a series of interesting facts about airplanes that not many people know about.
1. Airplanes have horns
Just like other vehicles, it turns out that airplanes also have horns. However, the plane’s horn is not used by pilots to warn other planes while they are in flight or simply to scare away birds.
Aircraft horns are only heard when the aircraft is stationary on the ground, for example when a technician is checking something in the cockpit and wants to attract the attention of other crew members outside the aircraft.
2. Generally the plane is white
Perhaps the question has crossed, why are most of the planes white? If you look closely, almost all commercial airlines give the predominance of white color to the fleet they use.
It turns out that the white color on the plane has a purpose and purpose, one of which is that the white color on the plane is considered to be able to keep the fuselage cool, especially since the plane spends most of its time at the Sun .
The color white is also used to make it easier for the airline to detect damage to the aircraft surface in case of cracks or oil leaks that leave a trail of a darker color than the color of the fuselage.
In addition, white is also considered to be able to avoid airplanes from attacks by birds in the air
3. The temperature on the plane is very cold
When you get on a plane, you definitely feel that the temperature inside the plane is so cold, especially when the plane is already above an altitude of 914 meters.
There is a reason why the temperature of the plane is very cold, the goal is that passengers do not lack oxygen which can cause hypoxia, which is a disorder when the body’s tissues lack oxygen.
It turns out that cabins with hot temperatures and high air pressure can exacerbate this condition. For this reason, the temperature in the aircraft cabin is lower or lower than the ambient temperature.
4. The door cannot be opened while the aircraft is in flight
Due to the strong pressure in the cabin, it turns out that the aircraft door cannot be opened as easily as one imagines when the aircraft is on the ground.
To open the door of an airplane in flight, you need to be able to withstand the pressure of 11,000 kg.
Deep inside the aircraft structure is also a lock that keeps the door closed.
These are interesting facts about airplanes that are rarely known. It can be useful.
