Took off from Orlando International to Atlanta. See how flaps aid lift at various speeds at takeoff and landing. Also see the use of spoilers in the landing process.
flaps increase the wing surface area. so they provide more lift at slower speeds. they lower the flaps for takeoff otherwise they'll end up not lifting off before they run out of runway because the plane can't reach lift off speed fast enough on a 12,000 foot strip. for landing the flaps settings are adjustable for different speeds. the flaps on the top are speed brakes (spoilers) which aid in slowing for descent. the flaps are lowered all the way down when the plane is on final approach just before touchdown at 175-180 mph. if the flaps weren't lowered they'd be landing at a dangerously high speed in excess of 220-260 mph and may not be able to stop before overrunning the runway
"flaps increase the wing surface area..." Not entirely correct. If that were true they would simply extend them straight back but if you notice on landings the flaps drop down considerably. It's not that they increase the surface area of the wing, but rather they change the profile of the wing giving it a
@@tchevrier yeah. You are correct, it doesn’t increase surface area but increases the wing camber thereby increasing the angle of attack in which the lift will increase
that is called a flaperon - Boeing invented those as a way to maneuver the aircraft more easily during takeoff and landing - it has two purposes controling the roll of the aircraft (as an aileron) and the speed and lift of an aircraft (as a flap)
The middle one moving fast is the Ailerons which control the movement and banking/turning of the aircraft, the slowmoving ones that gradually point down are the flaps which increase drag of the aircraft.
Only flaw I saw was after landing, it is a general practice to make NO changes to flaps (retract) up until clear of the runway. The unlikely, but possible mistake of putting landing gear up has happened on many occasions - more so in general aviation - nonetheless all my training focused on after landing checklists - with flaps up - after clearing runway.
Informative video - thanks for sharing. Had the same issues with focussing due to artifacts on the glass (in my case it was ice crystals), What was the aircraft type ? Defintely a 2 engined one but seemed a bit large for a 737.
+greysponge66 If your camera has a manual focus option, use that and set it to infinity. This will make the camera ignore window artifacts and not try to focus on them. On most consumer cameras such setting may be deep inside the camera menu, it might take some time to find it so you may want to search for the feature in advance. The airplane is a B767.
They are actually just fairings that cover the mechanisms that move the flaps. The hydraulics are used on the PDU (Power Drive Unit) that drives rotary actuators thru long torque tubes to both wings for each mechanism. You can see one of the green actuators under the spoilers, bottom right corner. 4:45
I find it a bit odd.. are they really tuning flaps immediately after plane has got airborne there? Isn't that a bit late? (I know flaps on before takeoff and off when flying)
***** Thank you, good explanation indeed. However I was puzzled about the FLAP adjustment sound immediately after plane had lifted off from ground. That seemed odd to me, as it seemed that they were increasing the flaps there.
+lxthomas except that the air beneath the wing travels faster, not slower, than the air above. That results in the oft-0=discussed wing-tip vortices (aka "wake turbulence) when the two airstreams come back together at the trailing edge. Back to flaps: flaps add camber (curvature) to the wing to cause the above, which, in turn, adds lift. A low flap setting upon takeoff is intended to optimize lift vs. drag until airspeed is adequate for lift. Flaps are set fuller on landing where both lift and drag are important. The drag on approach allows a higher power setting on jet engines without causing an increase in speed. The higher power setting is important because jet engines are slower to "spool up" on lower power settings. Hope that helps
+lxthomas the flaps on the rear and the slats in the front are designed to help a jet fly at lower speeds during takeoffs and slowing down for the final approach so they don't touchdown coming in too fast otherwise the jets weight (whatever remaining fuel, luggage, cargo, and with the weight of all passengers) combined will cause the jet to over run the runway on touchdown even with both engines on full throttle reverse
what the hell is that pilot nearsighted and he forgot his glasses or something.... That was more of falling onto the runway than a landing.... soaring soaring soaring over the runway......... PLOP... ok landing gear didn't break.... landed... all's good... everyone out..
I'm no aircraft expert but I think you were focused on the "safety ailerons" or something cause flaps wouldn't move that fast I would think. I think those were "safety ailerons" just so when taking off, the plane wouldn't slap the ground with it's wings so it has those for slow rates
I'm focused on the flaps. At about 1:40 you can hear the motor as the pilot begins to retract them. What you do see from time to time quickly moving up and down on takeoff is the inboard aileron. Thanks for watching
The "thing" between the inboard and outboard flaps is called a flaperon, it acts as a flap and as aileron. It's used for stability especially at low speeds :)
No information, no descriptions, no voice track or graphics, no banana. If you don't know how flight surfaces work, you won't get the video, and if you do, you don't need it.
Why is the Captain messing with the Flaps during Take Off and Landing its standard to olny do this wenn the plane is at 3,000 ft or during Taxi NEVER on a Transitioning Phase
Airplane Fan 1998 the plane I fly we retract the 10 degrees of flaps that we used for take off at 300-500ft to the get the best rate of climb, nothing wrong with retracting flaps while climbing so long and the climb is established and there is a positive rate of climb

Actually they increased the surface area so that aircraft won’t stall that early it basically delay airflow separation
@@tchevrier yeah. You are correct, it doesn’t increase surface area but increases the wing camber thereby increasing the angle of attack in which the lift will increase
Who uses mph instead of kts in aviation

I think flaperoni sounds better
@@LeftLaneHog.308 I agree lol
That hmmm sound made by flaps while retracting feels great!
The middle one moving fast is the Ailerons which control the movement and banking/turning of the aircraft, the slowmoving ones that gradually point down are the flaps which increase drag of the aircraft.
..and the small ones that spring up on landing are he ground spoilers
10 year old video but still a gem/useful here in 2023. Plane fundamentals still the same 👍🏻
Thank you
I have often thought, looking out of the aircraft window, I do hope the pilot knows that these things are slapping about like this.
5:03 i love that sound
The sound is so sweet.I like it.
Humans were not born with wings but somehow they have master the skies 😀
Great video. Thanks for sharing.
Thanks for watching
What is the small flap that moves up and down freely called? What is its purpose? Thanks in advance.
As a kid I always thought the plane was falling apart when the wings did that... Know I now better!!
4 minute flight? should've just walked there
No he skipped the video
+fatpigsarefat oh
+Samuel Petrina yea driving woulda made more sense
You're kidding right?
348frank348 😂😂😂😁😁😁😁😂😂
Hydraulics are loud planes are full of good stuff.
Sounds like this bird needs some power steering fluid 😂
is this really hartsfield Jackson..??
what is the airplane model? Airbus?

To me, it looked like the flaps didn't start coming up until after they were clear.
Put the flaps more down and turns to air brake when landed
Hi very good information
a genius invention that is used in all of Boeing's modern wide body aircraft 767 - 777 - 787 also the 727
That is the coolest things,just fascinated on how things works
This man is phaltu
Try this video on "how aircraft fly!!" How does an Aircraft fly ? : Flight lift theory explained (The Aerodynamics of flight )
depends on weight and runway landing flaps varies from the usual 15 to the more harsh 35
The triple 7's flaps only go to 30 ;)
My apologies, it is a 767...
They are the spoilers, to aid quick slowing down of the plane by increasing more drags thereby halting the plane quikly.
Well explained
Never sit next to someone in an airplane who had lunch at Taco Bell.
Thank you bro

corisco tupi
thanks for the info and the type of aircraft. Much appreciated
greysponge66 757
tks Simon
767 for sure
whats the name of those that keeps moving, those smaller pieces
Flaps
Ohhj..now I have better understanding...the function of the wing and the flap mechanically.
What is the small flap that moves up and down between the main flaps? If any one knows..
Its the fin the fin that turn you left and right
You hear that winning sound that is the landing gear and flap
That was one heck of a bumpy landing.
No, it's good enough for a landing
I said good, not butter Ok?
And How Spoiler Works.?
always wonder if the section in the middle just floats up and down ?
those help the airplanes to tilt and turn
Flaperon
you can say what you want...Flying is the fu***ng best on this planet :)
Thanks I play extrem landings
How many aeronautic engineers are watching 👇👍This
Looks like Orlando
If you like this video, you will love my channel so don't forget to subscribe. Thx
amazing
Yes the flaps makes the airplane take off shorter than without flaps but at less speed
Can someone tell me what those pontoons under the wings honestly really do
They hold the hydraulics that move the flaps
They are actually just fairings that cover the mechanisms that move the flaps. The hydraulics are used on the PDU (Power Drive Unit) that drives rotary actuators thru long torque tubes to both wings for each mechanism. You can see one of the green actuators under the spoilers, bottom right corner. 4:45
awesome ..
Thanks and i will be a pilot when i grow up and look like a bumpy landing and alittle annoying on that sound on that flaps and at Airline?
I see the ailleron been deployed here to lower the plane.
Why is there no winglets at the end of these wings?
Because they did not provide any
Not all planes have them
4:14 - did the plane land or was it shot down?
that is how planes land. no way to avoid that jerk when a huge object moving at hundreds of kmph touches ground
Mike Mac it was shot down by tomahawks
What model aircraft is that?
I think an airbus a320-200 because of how the wing looks
Dermot Hopkins it's a boeing 767
Dat *Flaperon*
What s the name of this aircraft ?
757
Good
The landing gears were crying???
No, the flaps were.
why does that flap in the middle keep moving up and down?
Those are the ailerons which control movement and banking
fatpigsarefat really? i thought ailerons would be placed more towards the wingtip and much much bigger, given the size of the plane....
Chris W They are. There's an inboard one (closer to the cabin) and the outboard one (near the tip of the wing)
fatpigsarefat ohhhh
It's called as *flaperon* ;)
Great
Looks very similar.
Lovely jobly

Actually the air over the upper surface of the wing travels faster creating a lower pressure than beneath the wing :)

The airlines safety video DURING TAKE OFF they should of done it during push back
I saw nothing BUT HE GOT A WINDOW SEAT!!!
I think no changes occur in flaps during takeoff
Falps area need to increase downside during landing
Why post this without any application of what is happening with flaps
Can't see a thing with the camera shake.
It's me or all the terrain in 1:30 is flooded?
It's flooded
you can see the flaperon , the same part that was recovered from mh370
Yes, a flaperon from MH-370, but that was a 777, and this is a 767.
767?
A380
boeing 767?
Yes
+Kevin Hartono yes
yep but don't be confused the 727 have very similar wings.
Asterope 727s wing spans are shorter than the 767s.
Doesnt even look close to 727 wings but it looks like a boeing 777
I never did like the sound of the flaps extending
I could tell this was a Delta flight based on that rough landing. Jeez
They even announce it was a delta flight who u trying to fool
steemdup It's a 767... they tend to have kind of noisy "clunky" landings due to the placement of the landing gear.
LOL, you mean because it's on the bottom of the plane? :))
Rough landing? The camera shakes more from the roughness of the runway than from the initial contact.
Its not the airline its the pilot you people think its alwayse the airline but check your flight name before flying
thats a hard landing
That’s what I said. No grace.
@@flori480 Agree.
this flight was just 5 mins?way wht!
humans technology is insane
Hire somebody to hold the camera still.
buy a ticket and go up to take it by yourself

Haaa.............Haa...............Ha..................lol.
Next time use manual focus, Autofocus likes to focus on droplets on the window
Good point
the shaking makes me dizzy to watch
No video commentary or explanation
Whatever happens....beautifully noisy plane, great hard landing and noise was excellent!

Flap 3 landing, its at 30 degree ,, that means its not table top runway ..
Coughing first few seconds of the video? Hard pass.

Put your pipes away we don't want to see where the fuel comes out when you have to dump it.

For what purpose?
0:04 ahahah
why are u using electronics during takeoff and landing
Good mechanism but terrible landing
Haha, always compare the delta landings with the famous US Airways landings on UA-cam 😂
Use brain dear it’s just showing how it’s work when takeoff nd landing about wings lol

find a way to hold your camera steady
No claps at landing means high IQ passengers.
