Although we often take planes, many people have limited knowledge about aircraft. There are certain aspects that people may not know, such as the difference between the seat belt tying methods in airplanes and cars, or why flight attendants place a hand behind their back during boarding. Today, we will explore some fascinating facts about flights.

1. Most airliner wings are located underneath the aircraft.

Have you ever wondered why the wings of most airliners are positioned beneath the aircraft? This design is primarily for safety reasons.

Placing the engines under the lower wing brings them closer to the ground, making maintenance easier. Additionally, in the event of an accidental landing, the wings can help absorb some of the impacts.

2. Cargo aircraft have overhead wings.

In contrast to passenger planes, many cargo planes have wings positioned on top of the fuselage, referred to as a "high wing" configuration.

This design facilitates easier loading of cargo onto the aircraft. It also allows for smoother landings on less specific or safe runways, prevents small debris from falling into the engines, and reduces air resistance during flight.

3. Most airplanes are white.

You may have noticed that the exteriors of many aircraft are white. The reason behind this choice is that white reflects sunlight effectively, preventing the fuselage from becoming excessively hot.

Furthermore, any damage to the white paint is easily visible, simplifying maintenance. Importantly, white paint is also the most cost-effective option compared to other colors.

4. Small triangles on airplane walls.

The small triangles you see on airplane walls serve as specific markings for flight attendants. These markings indicate the location of flashing indicators near windows.

They help flight attendants monitor the retraction of landing gear and the position of wings. If a pilot receives a signal indicating a problem, flight attendants can quickly locate the necessary window and address the issue.

5. Airplane seat belts are tied horizontally.

One common question that confuses people is why airplane seat belts are fastened horizontally, unlike car seat belts. The reason lies in the turbulence experienced during flights, which can cause shaking.

The horizontal seat belt design helps keep passengers securely in place. On the other hand, car seat belts use shoulder straps that require wider seat pitches, which is impractical for airplane designers. Moreover, car accidents generally involve higher impact forces than those experienced by airplanes, necessitating the use of shoulder-type seat belts.

6. Flight attendants place one hand behind their back during boarding.

Ever wondered why some flight attendants keep one hand behind their back during boarding?

They use a special device to count the number of passengers and ensure that everyone is on board. This interesting fact may be unfamiliar to many people.

7. Aircraft are protected from lightning strikes.

During severe weather conditions such as thunderstorms, it is common for aircraft to be struck by lightning.

However, under normal circumstances, airplanes remain unaffected. The reason behind this lies in the aluminum coating on the aircraft's exterior. Aluminum is a good conductor of electricity, effectively dissipating lightning strikes and protecting the aircraft.
