Airline Employees Reveal 12 Things About Airplanes We Always Wondered But Never Knew

Let’s get familiarized with some surprising facts about air travel.12 Things About Airplanes We Always Wondered But Never Knew

1. Why do pilots fly around with the landing lights turned on?Why do pilots fly around with the landing lights turned on?
If you are a keen observer, you might have noticed that pilots keep the landing lights on for several minutes after takeoff and before landing. Landing lights are so bright that they also make great anti-collision lights. When an airplane is climbing or descending near airports, pilots turn them on so that other pilots can see the plane. Mind you, these lights can be seen from miles away, even in daytime.(Image: Thinkstock)

Why do aeroplanes have a green light on one wing and a red light on the other?

Well, please don’t confuse yourself with red and green traffic lights here. In case of an airplane, a red light is mounted on the left side of the craft and a green on the right side. These lights help each crew member determine the other craft’s direction in a situation where the paths of two aircrafts cross each other.

3. Why do airplanes extend wing flaps?

Why do airplanes extend wing flaps?

The reason is quite simple. The flaps increase the off-ground lifting capacity of the aircraft without requiring a corresponding increase in angle of attack. In layman’s terms, this means the airplane can fly at slower speeds than it could without its flaps. This plays a pivotal role in landing.
4. Why do airplanes have blinking lights on their wings?

Why do airplanes have blinking lights on their wings?

Known as strobe lights, these are bright, flashing lights on the wingtips that serve to augment the airplane’s visibility at night. They are visible from miles away, and are turned off when operating in proximity to other aircraft as they can cause temporary blindness. And owing to this reason, strobes lights are not used on the ground.

5. Why do airlines dim the cabin lights for take-off and …

Why do airlines dim the cabin lights for take-off and landing?

This is a precautionary measure that allows passengers’ eyes to adjust more quickly to darkness. This is especially important during emergency situations, for passengers to maintain situational awareness to expedite escape.

Why do airline safety procedures require you to avoid using the toilet during take-off and landing?

Most of us know that take-off and landing are the occasions for most aircraft accidents. According to Quora user Jim Gordan, “The airline wants you out of the toilet compartments to give you a better chance of surviving any accident.” He cited two reasons behind this:· Toilets are not fitted with seatbelts and have hard, sharp surfaces that could injure you during an accident.
· Toilets are an enclosed space that could be blocked or jammed closed during an accident, and could become a death-trap in case of fire.Don’t you think that it would be awful to die or get rescued with your pants down?

7. Why do airplanes use nautical miles instead of kilometers?

Why do airplanes use nautical miles instead of kilometers?

A nautical mile (symbol M, NM or nmi) is a unit of distance, set by international agreement as being exactly 1,852 meters (about 6,076 feet). Ships and airlines use this unit of measurement because their captain wants to know how many degrees of the Earth’s circumference he/she has traveled and this also helps him/her to work out their exact geographical location at a given time. Therefore, using nautical miles for length and knots (nautical mile per hour) makes common sense when navigating and traveling long distances.

8. Why are the tips of some airplane wings bent upward?

Why are the tips of some airplane wings bent upward?

The reason behind this is that they help stop air below the wing from ‘leaking’ to the lower pressure region above the wing without themselves presenting a tremendous obstacle to the forward movement of the wing, its sideways movement in the event of a sideslip maneuver or the rolling of the aircraft while flying through the air. Apart from this, winglets give 3-6% fuel savings when cruising.

Here’s why passengers are asked to switch off all electronic devices before takeoff and landing

Most of us keep hearing the announcement to switch off or put our electronic device on flight mode, before takeoff and landing. But have you ever tried to find out the scientific reason behind it?Well, there are lots of radios fetching sensitive information from ground-controls in the flying aeroplane. If hundreds of passengers start fiddling with their smartphones onboard, it can cause electromagnetic interference with the plane’s control signals, which may even result in a serious accident. But with the advancement in the modern-day technology, this ban may get slowly removed as Emirates already allows onboard use of mobiles.

10. Why some planes leave white trails?

Why some planes leave white trails?

These trails are actually called contrails (short form of “condensation trails”) and are formed when the water in jet exhaust mixes with wet cold air, condenses, and freezes into ice crystals.When the air is wet and cold enough the trails can stay around for a long time. But nowadays, it’s very rare to see an airplane with a smoke trail apart from the deliberate ones used at air shows.
11. What’s the idea behind rising window shades?

What’s the idea behind rising window shades?

We all know that window shades have to be remained open during takeoff or landing of an airplane. The idea with raising the window shades has two purposes:· Firstly, your eyes adjust to the same lighting conditions that exist outside the plane so that if the plane lost lighting inside and if there is a need to evacuate in a hurry, your eyes will already be adjusted to outside conditions.
· Secondly, if an accident occurs during takeoff or landing, there is more visual access to the outside to know what’s going on at all times.
12. Did you know why airplanes have headlights?

Did you know why airplanes have headlights?

Airplanes have several types of lights operating on them. They can be divided into to major categories:· The ones that help during Navigation
· The ones that help during landing/taxing”Headlights” refers to the landing/ taxing lights. As the name suggests, taxi lights are used to illuminate the runway while taxing that helps the pilots identify the gate, runway, identify hazards and obstacles on the runway etc. It is situated just near the nose landing gear. On the other hand, landing lights are used to illuminate before the plane lands.Both these lights are extremely bright and therefore used only until the plane arrives at the gate and are turned off. Mind you! It could cause potential retinal damage to the ground staff on prolonged exposure).
