Question

What is the name of the device on an aircraft wing that lifts and decreases speed?

Answer 1

Flaps..and are located on the  trailing edge of each wing..Lift is achieved by the design of the wing. Air travels a greater distance over the top of the wing, than the air passing  below, this causes "lift" hence flight. To test this get a soup spoon turn on a water tap hold the spoon genitally between thumb and forefinger  at the end of the handle, move the spoons curved base gently towards the running tap till the water flows over it. you feel the spoon drawen  to the left or right depending on how you have offered the spoon to the running tap. Very good question.......

Answer 2

Flaps give more lift, but with that increased lift is increased induced drag. Which in turn slows the aircraft down.

These are fully extended for landing and also used at smaller angle settings for takeoff.

Answer 3

This depends on the intention of the  phrasing of the question.

If the question is meant to read "What is the name of the device on top of an aircraft wing that lifts or pops up and decreases the plane's speed then the answer is the spoilers or speedbrakes.

If the wording is meant to suggest "what is the name of the device on an aircraft wing that enhances lift and decreases speed" then the answer is flaps.

The wording is slightly ambiguous.

The slotted flaps on the trailing edge of a wing both increase lift and increase drag on a wing, decreasing speed. The flaps help a plane to fly at a slow speed without stalling and falling out of the sky. The added drag from the flaps help stop the plane from picking up too much speed as it descends from altitude. The flap settings for take-off are less steep than for landing so that the added drag does not consume too much engine power.

There are a number of types of flaps and large passenger jets use multiple slotted flaps and leading edge slats. When a large plane comes in to land you see the whole wing seem to come apart like a transformer, and this is to increase its surface area and modify its airflow, increasing lift.  The slots between the flaps on the back of the wing feed air over the top of the steeply angled flaps and prevent them "stalling".

Ailerons are the flaps at the outer section of the wing and they move in opposite directions to make the wing on one side of the plane temporarily generate less lift than the other, causing the plane to bank to its side so that it can turn.

Spoilers increase drag and decrease lift, "spoiling" the airflow and spoiling the lift over the wing. They can help a plane lose altitude quickly and are deployed after touchdown so that the wheel brakes can get plenty of traction and the still speedy plane won't float over the runway in ground effect.

Answer 4

Flaps NOT Ailerons

as said by someone

Answer 5

Speed brakes and spoilers.  

And spoilers do not advance from the leading edge.

Answer 6

Here we go again with the BS artists on this topic.   Pat S had one of the right answers AND SOMEONE GAVE HIM A THUMBS DOWN!!    What is with you wannabes?  I understand someone wanting to be a pilot,  but for those of you who want to go to flight school, you'd best get out of this habit of BSing when you don't know the answer......that's the quickest road to washing out of flight school!!.....so get your heads flushed out, cadets!!    The answer is SPOILERS! boys and girls...SPOILERS!....NOT ailerons....NOT flaps....the questioner wanted to know the name of the device that "lifts" and "decreases" speed...He has described a device that HE has seen and that HE is interested in...NOT the fantasies that are going around in your heads!!.....and the devices that fit HIS description are the SPOILERS.  Shape up, newguys!!

Answer 7

I believe they are called ailerons, commonly known as flaps. These are hydraulic sections at the leading edge of both wings that are moved in order to improve lift on take off and increase drag (slowing the plane for landing).

Answer 9

There are 3. Spoilers (the ones that it sounds like you are on about), flaps and slats.

Answer 10

Flaps

Answer 11

maybe you're talking about the Spoilers (Air Break) i think thats what you're talking about  since it is also used to aid the pillot to dcrase their altitude during landing and also, during landing Autobreaks are used and with the hewlp of the Reverse Thriust it said tyhat in wikipedia, that spoilers differ from air breaks so hope it helps :)

P.S.: look here ive been telling everybody that whoever finds this answer wrong just message me so i can delete this i just dont like to give my self a point just by aswering wrong answers all i need is someone who is a very kind enough to message me telling that to revise or change or to say "please kindly delete your answer its a wrong one"and not just putting a finger down rate okay thanks!!

Answer 12

Flaps,Air brakes.

Answer 13

The engine

Answer 14

Slats Spoilers used on the leading edge and Flaps extend downward on the trailing edge. Many fighter jets also have an air brake that lifts out of the fuselage aft of the pilot. Low speed flight is tricky in jet engined air craft. That jetairliner's tires hit the ground at 160 miles an hour and  landing gear support the the weight of four greyhound busses.

Answer 15

Flaps, ailerons, spoilers and air brakes are all different things!  If it lifts from the wing then it will be an air brake.  Flaps extend together from the rear of the wing, ailerons operate in different directions on each outer wing trailing edge, spoilers advance together from the front edges of the wing into the air flow.

Answer 16

Flaps

Slats

Answer 17

The little thing that lifts on the wing to decrease speed is the air brake (or spoiler, as it spoils the airflow over the wing).

The flaps go down at the trailing edge of the wing to increase lift on the wing - important at slow speeds.

Ailerons work opposite each other on the trailing edge of each wing. When one goes up, the one on the opposite wing goes down - these are used to change the aircrafts direction.
