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
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.
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.
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'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!
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
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
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.
@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.
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.
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).
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).
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.
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.
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.
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.
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.
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
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.
Don't talk about things you're not sure about. The plane's logo lights and nav lights should ALWAYS be on, no matter the time of day. The beacon lights should be on whenever the plane is moving, OR when the engines are running. The strobe lights have to be on when you enter a runway, until you land again and exit that runway.
Swing and a miss! The air actually moves at a higher speed *UNDER* the wings than it does *OVER* them. The wings are curved on the top and flat underneath. The spoilers on racing cars, however, are the other way around. They're curved underneath and flat on the top, so the lift they create is pointed down, increasing downforce and thus improving grip, which is what you want in a racing car trying not to lose grip in that tight bend at barely more than 70 mph. In a plane, however, which is meant to fly, this is not the case. You want to get airbourne. With that wing shape, the air pressure underneath the wings creates a wedge of dense air that lifts the plane off the runway.
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
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.
1. We didn't invent winglets. We learned it from the birds 2. You are right. The only reason we board from the left side is because of the maritime tradition where the port is on the left side of the ship
i learnt a lot of new things but the facts that wowed me was that witched have pointed noses and they can go at a super sonic speed (faster than speed of sound)

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
