Why Lights at Plane Wings Are Different


Do you notice every little detail about your
surroundings right away? If yes, then you didn’t miss the fact that
all planes have a green light on the end of one wing, and a red one on the other. Why do they have different colors? Well let’s find out! These high-intensity red and green lights,
together with a white light located on the tail, are the plane’s navigation lights. The red light is always on the left wingtip,
and the green one is always on the right. These navigation lights are on at all times. Their main purpose is to signal a plane’s
precise position to all other aircraft in the sky. Let’s say, a helicopter’s pilot sees red and
white lights in front of them at night. This lets them know there’s a plane passing
from right to left. Green and white means the plane is flying
from left to right. Seeing both red and green is a warning sign
that a plane is moving toward the helicopter. And spotting only white light means a plane
is going the same way as the helicopter, or pointing away. All these light combinations help pilots to
avoid any chance of collision with another aircraft Apart from navigation lights, planes have
red rotating beacon lights installed on the upper and lower fuselage. When the red blinking light is on, it’s a
warning for the ground crew and other planes that the engines are about to start, and it’s
dangerous to come near. But pilots keep them on even after take-off
because they increase a plane’s visibility in the sky. And just like a car, a plane has headlights
that help the pilot see the runway during landing and take off. Taxi lights are located on the nose, and they
illuminate the runway. Landing lights are under the wings near the
fuselage. They’re used for the same purpose, but give
the pilot a bit wider angle of view for making turns. During take-off, landing lights are switched
off when a plane reaches 10,000 ft altitude. When descending, pilots turn them on again
at the same altitude. But what lights do you see when you notice
a plane high in the sky? These are the white strobe lights fitted at
the wingtips. They’re super bright, and pulsate to make
a plane visible from miles away. Ok, now all those blinking lights make perfect
sense. But a plane has a lot of other not-so-obvious
things that have some hidden purpose and spark questions, even for the most experienced travelers. For example… Why are there white spiral marks on airplane
engines? These spirals come in different sizes and
shapes, depending on the plane, and protect the ground crew. You might think that deafening noises are
enough to warn them that the pilots have started the engines and it’s not safe to approach
the area. But they wear hearing protection. Also, if there are several planes on the ground
it gets really hard to tell which one is about to take off by simply relying on your ears. Seeing the hypnotizing swirl on jet engines
prompts the ground staff to stay away. Why are there holes in airplane windows? Take a closer look at any window on a plane
– it consists of 3 panes, and the middle one has this tiny hole. When a plane is up in the sky, there’s a huge
difference between the pressure inside and outside the cabin. The outer pane bears the most pressure, and
the hole in the middle one helps regulate the pressure difference to make sure passengers
don’t experience a lack of oxygen. And since there’s also a big difference in
temperature inside and outside, the hole keeps the windows from fogging up. Why are there hooks on the wings? Some of the emergency exits on a plane are
over the wings. This means that passengers will have to step
on the wings to get to an escape slide. But if it’s an emergency landing on water,
the wing surface will be slippery, and this is when those yellow hooks come in handy. Crew members secure one end of a rope in the
door frame, and the other one gets attached to the wing through the hook. Another rope is secured in the second hole. Passengers can hold on to these ropes while
making their way to the inflatable slide. Is it possible to get extra space on a plane? Yes, but only if you’re lucky enough to
take an aisle seat. There’s a magic button near the hinge under
the armrest closest to the aisle that will make your trip instantly much more comfortable. After pressing it, you can freely move that
armrest up, making it parallel to the back of your seat. However, the main purpose of this button is
to allow you quick and easy escape in case of emergency. Did you know about this secret feature? Let me know in the comments! Why are the lights dimmed during take-off
and landing? When a plane takes off or lands at night or
dusk, the cabin crew wants your eyes to get adjusted to the darkness. Usually, it takes up to 30 minutes to fully
adjust to a dark setting. So, dimming the lights in the cabin works
to shorten that period. In case of any emergency or sudden evacuation,
your vision will already be adjusted, and the illuminated pathways will be more visible. However, dimming the lights happens in the
daytime as well to conserve some engine power. Why do planes leave white trails in the sky? These white trails look a lot like smoke,
but in reality, they’re mostly water and carbon dioxide, which are released into the atmosphere
when the engine burns fuel. The cold air at high altitudes condenses,
and possibly freezes, the hot exhaust, creating those white “tails”. Basically, it works the same as when you can
see your breath on a chilly day. Can a plane door open mid-flight? If, for some reason, this question worries
you when your plane is about to take off, then let me put your fears to rest – it’s
impossible. The force of the cabin pressure won’t allow
it. If someone tried, they’d have to overcome
more than 24,000 lbs of pressure. To give you an idea, that’s the weight of
20 polar bears or 6 cars. (You wanna weigh a polar bear! Be my guest!) In addition to the pressure force, there are
lock bolts located deep inside the structure of the airplane that hold the door together. Is it safe to fly in lightning? Generally, yes, because standard commercial
airplanes are designed to withstand lightning strikes. Their lightning protection systems serve to
prevent electrical build-up. However, statistics say that lightning still
hits every commercial plane once a year. But in most cases, this leaves a plane with
only minor damage, like a scorch mark on its surface. Why are seats and windows not lined up on
some planes? Actually, all commercial airplanes are designed
with seats and windows perfectly aligned. But when a specific airline buys a plane,
it’s up to them to decide how many seats it’ll have. Quite often, airlines choose to add extra
seats because more seats mean more people, and more people mean snacks – no, more money. And that’s how you end up in a cramped space
without the possibility to fully enjoy the sky views. What’s the safest seat on an airplane? Most airlines insist that there is no safest
seat. But the statistics of airplane crashes supports
the idea that it’s at the back. Passengers near the tail of a plane were about
40% more likely to survive a crash than those in the front. If you want an even more specific answer,
then it’s the middle seats in the rear section. Why do flight attendants touch the overhead
compartment so often? You might think they just check if it’s
tightly closed. But nope. They use a hidden handrail for balance! It’s located at the bottom of the overhead
compartment. Next time you’re making your way to the
bathroom, tuck your fingers into it for a steadier walk down the aisle instead of grabbing
the seats of other passengers. Thank you. Where do flight attendants nap on a plane? Many airliners have secret, windowless bedrooms
for the cabin crew that include from 6 to 10 bunks. Their location may vary depending on the plane,
but they’re usually right above first class, behind the cockpit. To get there, the crew uses stairs hidden
behind a door near the cocktip. But on some planes, a special hatch that looks
like a typical overhead bin allows the cabin crew to enter the rest area. Depending on the airliner, some pilots have
their own private overhead area to rest. Finally, how to they twist those big rubber
bands so much in order to spin the propellers? Well that’s a highly guarded secret that
even we can’t reveal. That’s a joke. Hey, if you learned something new today, then

    Do not believe the "contrail" misinformation. True, there is a contrail effect but that only lasts for a few thousand yards. The horizon to horizon particulate that's sprayed is geo engineering

    One small oversight in this video: "Seeing both red and green is a warning sign that a plane is moving towards you." That is true but only if the green light is on your left with the red one on your right. If the colors are reversed (red on your left & green on your right) a plane is moving away from you.

    A couple hours ago I rode on a plane and I sat right next to the left wing and was confused why I saw blinking red lights and it also stopped once we got higher

    I've heard that in some countries Pilots use these lights to point the plane in the right direction for takeoffs.

    the reason why airplanes have diffrent lights is to let aircraft , know where exactly they are in the sky, and to let the aircraft know if the airplanes are coming from left to right and left to right

    basically if a helicopters pilot sees the red and white light in the sky , it lets them know ,there is plan coming from right to left.
    if the helicopters pilot sees the green and white light it in the sky it means the airplane is coming from left to right.

    Ships use the same light system for avoiding collisions. The green light is for the starboard side(right) and the red light is for the port(left) side. They both have an arc of visibility 112,5 degrees. The masthead light is 360 degree visible

    5:03 my whole life is a lie I always thought that the white trails only comes from military jet planes only kudos to our elders in Philippines who thought us that😂

    Why don't they install CCTV cameras in the cabin of a plane? I think being able to see everything that happens during a flight is helpful in case it comes down like the case with the Ethiopian Airlines plane in March this year.

    Okey, my guess before i watch the video is that there are different lights on airplane wings to know wich way the airplane is heading.
    Edit: That was an accurate guess!
    Btw, the triangle symbol over the middle seat makes it much easier for you to locate the wings. If im not wrong, thats the best lookout spot from a plane seat.

    so that even in total darkness you will know if a plane you see in the distance, is heading towards you, or away from you. this is the case with ships too.

    I see this all the time at night, before takeoff pilots turn on the wing headlamp to give more vision stability and giving me a chance to see the runway.

    An old coworker once told me that a friend of his who was a commercial aircraft mechanic took an old nosewheel light that he had just replaced and mounted it onto the front of his truck. One night whilst he was driving down a long stretch of highway he encountered an oncoming car that had its high beams on. He blinked his lights to let the other vehicle know that his high beams were on with no success. He tried a couple more times and again nothing. Finally, he had had enough and flipped the switch to turn on his new other light. The dark countryside wasn't so dark anymore and an " I showed him. " of triumph was no doubt being felt. That feeling of vindication was very much short-lived though as the other car turned on its other lights which were red and blue…

    What you didn't mention is that the red and green lights also show right of way. In the air, as well as on water, or on the road at a stop sign or intersection, a vehicle approaching from your right has the right of way. So you see a red light. If the vehicle is approaching from the left, you see a green light because now you have the right of way.

    Q : why do lights at plane wings have different colors?

    Me : oh come on, man. Rightists and Leftists need to have their own symbols.

    Like two cars converging at a four-way stop, the one on the other's right has the right of way. Same with planes. So, if a pilot sees a green light, he know he has the right of way. If he sees red, he must change course to let the other pass..

    I already know this planes are the ships of the sky’s and they did the right starboard red strobe and left port side green

    By those white trails you can also identify whether its an international or domestic flight from ground
