In the trend of globalization and the global village, airplanes have become the fastest, most convenient, and most common mode of long-distance transportation, with nearly 4 billion annual flight passengers. And during such flights, there are many little-known secrets. Here are seven surprising aviation facts for everyone.

1.The captain has absolute authority on the plane
The captain holds the highest management authority during the flight and can command everyone on board under both normal and emergency circumstances. If the captain determines that someone is posing a threat to aviation safety during the flight, they can arrest or detain the offender or suspect. The captain also has the right to deny boarding to anyone disrupting cabin order. When exercising public security management authority on the plane, the captain is exempt from civil, administrative, and criminal liability.
2.Pilots and co-pilots eat different meals
To reduce the risk of both the pilot and co-pilot being poisoned by food at the same time, the meals prepared for them on the plane are different. If one of them gets sick from the in-flight meal, at least the other pilot can still operate the aircraft normally.

3.Flying can make you especially want to cry
A U.S. survey found that 41% of men have cried while watching a movie on a plane, and 55% feel they are especially prone to crying while flying. There’s actually a reason for this—stress during travel, lower cabin air pressure, and slight oxygen deprivation can all affect mood. So next time you get teary-eyed during an in-flight movie, don’t feel embarrassed.
4.The air on a plane is as dry as a desert
Your skin and throat tend to get very dry on a plane because the humidity of the pressurized cabin air is kept below 20%, which is about the same as the average humidity in the Sahara Desert in Africa. Your body loses about 220 grams of water per hour on a plane,ifyou’re on a 12-hour long-haul flight, you could lose over two liters of water. So be sure to drink water regularly.

5.You lose a third of your taste in the sky
It always feels like airplane food doesn’t taste good, and there’s actually a reason. Your ability to perceive sweet and salty flavors decreases by nearly a third at an altitude of 11,000 meters, and the relatively low air pressure and humidity in the cabin also affect the nasal mucosa responsible for smell. So next time, don’t blame the airline chefs.
6.Dimming the cabin lights during takeoff and landing has nothing to do with atmosphere
Dimming the lights is to help passengers adjust to a darker environment. Since 80% of plane crashes happen within five minutes before or after takeoff and landing, if an accident occurs and the cabin lights suddenly go out, passengers can quickly adapt and follow the flight attendants’ instructions to evacuate in the dark.

7.The sky is more crowded than we think
According to real-time flight tracking website FlightAware, atany given moment, there are on average9,728planes and1millions2of people flying in the air—only slightly fewer than the total population of Estonia, an Eastern European country. Can you imagine? While you’re reading this article, half of Taiwan’s population is in the sky.
