Why You Board the Plane from the Left
소스 코드
- 게시일 2020. 01. 19.
- When you hear “airplane” you think of a “big, white, a rounded nose, relatively small tires, two oddly angled wings with their tips curling up, normally late taking off. Oh, and you always get on board through the left side!” But have you ever wondered why is it always the left side?
And, why are do the wings have curved tips? Or, why is the entire wing tilted upward instead of being perfectly parallel with the ground? Most airliners have nicely rounded noses, but there are jets with pointy ones - so what decides it? Let’s see!

SUMMARY:
-Wings angled backward help planes be as fast as they are.
-Wingtip vortices lead to slower speeds, more fuel consumption, higher CO2 emission, and safety issues.
-Upward angle is crucial for the airplane's stability. That stability is at risk when a jet comes across some obstacle, like a bump from turbulence, that can make it roll to either side.
-If you tilt the wing too much, the lift will get weaker or disappear altogether! Then the plane will stall in the air and eventually fall. If the wings are tilted down, the lift decreases.
-The tilt serves several purposes: to soften the landing and absorb the touchdown shock, to level the plane and prevent it from pitching forward, and to let the gear fit properly in the gear well.
-If you made airplane wheels bigger, it would add extra load, and aircraft would waste more fuel carrying them.
-Thanks to huge pressure inside them (as well as the material they're made of), airplane tires don't burst under the immense weight of a landing aircraft.
-The lighting scheme helps pilots figure out the direction of oncoming planes in the dark and avoid a collision. The green and red lights on commercial aircraft must be on from sunset to sunrise.
- The faster a plane is, the sharper its nose will be since they need to cut through the air without meeting too much resistance. That's why almost all supersonic aircraft have pointy noses.
-The right side is used for fueling the plane and loading and unloading baggage and cargo. If passengers were also entering aircraft from the right side, it would mess up the whole process and probably lead to accidents.
-Some airlines do use both for boarding and deplaning. But if people board an aircraft through a jetway, using both doors won't work. Jetways only reach the front left entrance.
-Some airports are just too busy and don't have enough gates. It's either using buses and mobile stairs or waiting for hours for an available gate.

I thought we were talking about why planes board passengers on the left, not the design and physics behind every single aspect on a commercial aircraft
I agree
Imagine this clown working in a sandwich bar? You'd get the low down on all the equipment and 5 hours later ' hello what would you like today?' 😂😂😂

It's a strategy many channels use to get more views. When they want to talk about various aspects of a subject, they choose the most interesting aspect and use it for the title. It'll get more views that way instead of, this video for example, being titled "Why are planes designed the way they are?" Nothing wrong with it in my opinion as long as it isn't a "how to" video or if they go completely off topic.
FYI. Southwest in the US boards and deplanes through both front and rear port side doors in select airports while using both a jetway as well as stairs. No buses are used to transport passengers to the terminal.
Winglets don’t remove wingtip vortices, it only minimizes the amount produced.
Navigation lights (red and green lights on wingtip) doesn’t flash, strobes (white) and beacons (red) (anti-collision lights) do.
Xavier Thomas Thank you. Someone else who actually knows something
some older planes and helicopters have flashing nav lights (uh-1h or dc-6).
Delta's old 727-200's had red and green flashing wingtip lights instead of strobes. I think they were the only airline that did
Xavier Thomas I think that winglets help minimize turbulence.
@@justplanes295 not winglets reduce drag which in return saves fuel
The content you produce is truly amazing! Thank you very much for sharing, plz continue uploading!
Winglets also highly used for being more fuel efficient (just thought to explain this as the video seemed to make it look like it is a small thing)
I'd wondered about the wingtips. Now I know! I've been on an aircraft that flew into one of these "mini-tornadoes". Let's just say several people screamed their lungs out as we dropped. Of course, I wasn't one of them......
Boarding from just the front left also allows the stewards to check each passenger as they board. We are visually "scanned" to determine possible threats. They can't block the obnoxious guy you end up next to who wants to show you 200 pictures of his kids playing baseball, but otherwise, they're just doing their job to best keep everyone as safe as possible and the flight boringly uneventful.
Thank you for the video!
In the winter at Palma Spain, easyJet can use the Jetway, airbridge for front loading, and rear steps as well. Just open 2 check-in desks next to each other. It can also speed up boarding.
2:54 “aircwaft wings” 😂😂😂😂😂
okay...I thought I was the only one!
2:52 "Air kwaft wings are an engineering marvel."
You heard it too?
4:04 butter landing lol 😂😂
The upward angle of the wings is called dihedral. You see this on often on low and mid wing configurations. Conversely you'll see anhedral on many high wing planes such as dedicated cargo jets such as the C-5 Galaxy.
One of the reasons that we load on the left probably reaches back to medieval times when knights would carry swords. Because most people are right handed the sword would be carried on the left. When mounting a horse with a sword on the left you have to swing the free leg (the leg opposite the sword) over the back of the horse to sit in the saddle. This tradition is carried on today with horse riding. Most still climb on a horse from the left. this is why we board ships and planes on that side.
I have been wondering since I was younger, thanks!
Some smaller airports don't use jetways but rather just rolling stairs. I know when I flew to Jackson Hole, WY, this was the case. I think the other reason is for safety and passenger comfort. It's less noisy when you board through a jetway (plus if it's raining or snowing or windy outside this makes boarding and waiting in line easier to deal with).
Great video..very informative. Thanks

Mr. F2P thank you
I’ve always wondered that 😂 thank you for answering!👀
Immortal Doggo google doesn’t give you straight anwsers.
Immortal Doggo when I googled it it just had websites
@7:30 some gates specially for widebodies at Amsterdam Schiphol Airport has 2 jetbridges that can be used. The fwd is common as we know and the rear one goes over the wings to the back.
Nice informative video. Thank you Bright side!!!
Really the only airliner with a pointed nose doesn’t fly anymore. That plane is Concorde, and when it flew it was one of the fastest planes carrying passengers
it wasnt one of the fastest planes carrying passengers, it was the fastest
Because they were supersonic, as this video explained.
TLDR: Supersonic = pointed noses. Subsonic = rounder noses.
Interesting fact; the nose is where the radar dish is located.
Your comment is worded to where people who dont know much may think because it had a pointed nose it was the fastest commercial aircraft....the nose was pointed, and the aircrafts' profile was long and narrow, because of its speed and such a nose was required to pierce through the air not only to reduce drag but also friction which created extremely high temperatures at supersonic speed. The nose of any aircraft is designed to displace as much air as possible so less air impacts the airframe. The space shuttle, which reached hypersonic speeds had a blunt rounded nose to move as much air out of the way as possible to accomplish exactly that. Reduce the drag, reduce the friction and high temperatures. Theres no point putting a long nose on a big aircraft because it wont do its job. Just as a big blunt nose works against a long sleek aircraft profile
@@daviddou1408 No!... *it wasn't, it was* .....Because paul cowen is mentioning of one particular model. He is not mentioning the number of planes, that the particular model has. That is immaterial. You have to understand the context. Paul cowen's language is correct
Answers: it’s tradition, and they have to use the other side for guiding and the other for boarding.
Some great trivia material in here! 🙏👌👌
Wonderful video good information well done keep it up
"Airliners have blunt noses..."
Concorde: Am I a joke to you?
Very informative for this aviation enthusiast.
Concorde = supersonic (famously)...
Maybe you guys should’ve titled this “Want to learn some random facts about planes?”
then majority wouldn't have clicked the video.
This is so amazing.. you answer the questions I didn't have !!

Mr. F2P - Mostly Aviation small compared to the size of the plane. ✈️
ahem.... *relatively small*
They just don't need the 3 chassis
You clearly missed the word "relatively"
It's clear you don't understand what "relatively" means🤦♂️

I love how the first 5 minutes had nothing to do with why you board from the left.
The answer we were all waiting for is that the bulk of early aircraft were military - in WW1 - and many of of the early military pilots were drawn from the cavalry. We all know that you mount a horse from the left because for thousands of years you would have a sword hanging on your left side, so physically couldn't mount from the right; the pilots therefore found the left side the obvious one for boarding. Regarding ships, for thousands of years these were steered by a large paddle hanging over one side of the stern - these were called steer-boards in whatever language. As the majority of people are right-handed it was necessary to hang the board so the right arm could hold it - the right or steerboard side, latterly Starboard. When docking, to avoid damage to the steer board the other side - the left - was habitually placed nearer the land and so was referred to as the port side (after the Roman harbour called Portus which led to the generic term "Port" for any harbour in western languages).
Can you please make a video on white holes??
I always get on the airplane on the left side because that’s where the door is.
tntkop right😭😭
I get in from the right because I just jump up there (I’m being sarcastic)
4:18 back in middle of the economy section. He sure knows who his viewers are
At 8:06, the graphic shows planes parked with the jet bridge on the "wrong" (starboard) side, for no purpose.
Awesome👏✊👍 Bright side.
love you guys brightside
2 also who loves bright side 👇🏽👇🏽👇🏽👇🏽👇🏽👇🏽👇🏽👇🏽👇🏽❤️❤️❤️❤️
Who else came here becuse they are going to travel soon and are really excited
No one? Mayybe its only me
Ahaa now I know. Thanks 👍
Also, I think that there is another reason for tilting back. It could be that since there are more tires at the back, the load of the entire plane gets distributed evenly among them, rather than having 1 wheel take all of the load. Airlines would have to put a giant wheel on the front to hold the weight of the entire plane.
Umm ships use both sides actually, it just depends where they’re docking
This many people are watching before bed
Faith Quilter fell asleep yet? 🤦🏻♂️😂😂😂
me right now
I'm going to the airport in 8 days and its 10:40pm
Everyone technically does this. I'm watching this before bed although bed time isn't for well, over 24 hours.
What !! You are right man .

Good background music 👌
Tqu so much u r an inspiration to me 😊
First off, there is a 5 mile distance rule between planes, and second, planes must be 1,000 feet apart vertically.
Tru bro, but what he explained is correct, except the scenario would be when planes are queued up for take off, having winglets help clear the runway of any vortex faster. Saving take off time for next plane in queue.
A plane crashed in NYC just after 9/11/2001 because of this phenomenon...
Bright Side: when you do a 9 minute video over one simple question.
An I like it
Its interesting!
Cool,i often tell these videos to my classmate they are also fans of Bright Side😊
Except in special circumstances, no passengers are allowed to board until aircraft servicing is complete. Back in the ‘70s I drove a catering truck at JFK and we often loaded from the left side, depending on th aircraft type and galley being serviced (First or Economy). Aircraft catering is labor intense and fast-paced. You can’t have passengers in the way while it’s happening.
Title: Why get on from the left
Me:because that’s where the door is ;w;
睡眠 不足 シ They’re on both sides. Not funny
L:
@@rascallygoose4926 r/woooosh
Zach Aoi I don’t care. This ain’t reddit. Also, jokes are meant to be funny.
5:41 the title of the video.
It is kind of funny that right the bit about single door boarding using a jet bridge, you have a video clip of a dual door jet bridge :-) That is at 7:55 in case anyone missed it. There are over wing jet bridges too. Amsterdam has those.
Albany International Airport in NY has jetways that allow airplanes to board and deboard from both the front and back of the plane. So some Airports now have jetways that allow for boarding from the back and front of the airplane. So your video has that info sort of right.
More like “how aircraft fly ?”
... and he actually got it wrong
@@Kyrelel so if you know that he is wrong can you tell me the correct answer
Don’t know how this video has 25 likes with 15 views but it does

Than there will be no ship
Not funny
ur confusin it for subs?
@@user-rl8uk ight than don't read it
Here is the answer: THE DOOR IS ON THE LEFT
Um. No planes have doors on both sides.
Baffy. I mean yeah
Doors will open on the left.
It's because it's standardized to be done that way, the gates turn left, and the baggage and fuel compartments are on the right.
@@depdarcsoft7648 this guy said that plane's doors are on the left
Yes I did learned something about airport, airplanes and passengers
Question about boarding from the left ended at the end of this long video. Answer is uniformity just like where the steering wheel is located in our vehicles and is purely arbitrary some countries on the left, others on the right.
With all these other flight tests, done purely by experimentation, but rather than making a full size model, very small models with hundreds and thousands of wind tunnel tests. Some mathematical models were generated much later.
But who is designing the plane? The engineer or the guy that wrote the program? My old company was manufacturing strain gauges to measure stress. Engineers were trying many different configurations, guess work if you may to decrease the strain gauge readings, numerical proof.
Thermodynamics was about the same thing, could study all the equations, have some good ideas, but wasn't until you built and tested the prototype would get the correct answers. This takes time.
See young engineers tying to design electronics by computer simulation, will never replace years of experience and limited by the programmers experience. Ha, often made the comment, they wouldn't have enough sense to replace a burnt out light bulb if they didn't run a simulation program first.
Over 5,000 wind tunnel tests was conducted on the Airbus 380 and all the changes were done by guess work. Are you a good guesser? Arthur Emmons Raymond was a good guesser, maybe not with over 2,000 wind tunnel tests for the DC-3. Ha, a good guesser would be less than ten.
Right door for emergency
This is so cool.
6:14 Some aircraft are fueled on the left. 767s in particular.
Here’s an answer to a question I never asked ig? 🤷🏽♂️
Plus if all loading or best part of it, was done from the rear and seated, there could be a problem with balance, as I know of one jet and another aircraft that toppled down on its tail.
Thanks😄
reply to title: because there was no entrance on the right side :D
Yes there is.
did enyone heard that bright side sed aiycwaft that is so funny 😂😂😂😂😂😂🤣🤣🤣🤣🤣🤣
Yea
2:53
The other reason why wings are angled upwards is also to do with load under flight not just to help be more stable and be able to recover as you mentioned air pressure above the wing is greater than that below so during a flight a say for arguments sake the Wings are angled 20% during flight that will be lower as the wings and flex downwards in flight roughly speak that's my understanding of it but please correct me if I have it wrong lol
Nice, bright side
2:54 he say air cwaft wing
Heyyy I'm early where's my like :)
Very nice...
The reason for bording om port side, is due to the ships rudder is on starbord on old ships.
The maritime traditions where brought into flying.
The lights are the same color and you yield to the same side.
Later, when designing newer plains, it was natural to have maintenance happening on the opposite side the the boarding..
Aircuaft wingss 2:53
Bro you don’t know anything about planes, as an avgeek im scared for you
Very interesting
Good info. please show function of flaps, ailerons, rudder and speed brakes next time.
FALSE: the reason why planes land on there back wheel is so the aircraft can slow down way quicker if you don’t it is a really high chance you will over run the runway
Main load bearing wheels, and the center, the front is for steering and to balance
You're referring to aerobraking.
pilotguy707 yes indeed but it sometimes happens and the nose gear did not give way
pilotguy707 100%
In some big airports the bigger planes like the A380, 747 and 777 can be boarded by 2 jetways. Sometimes even 3 in case of the A380.
Earliest in Bright Side...my flight was canceled because of the volcanic eruption in Taal volcano Philippines last week
everything was correct in this video but they kinda got Angle of Attack wrong but oh well. good job keep making videos
