Airplane taking off?

Question

When a plane is at the end of a run way and is about to take off you see th pilot set the flap to the required degree. My question is when the plane gets to take of speed and the pilot pulls on the yoke do the flaps extended further if not what actually makes the plane lift up.

I have read all the answer so far some have been ambigious and some have not answered my question. Putting it simply when the flaps are set what makes the plane rise when take off speed reaches...which part is adjusted to get the nose into the air.

Answer 1

Although some airplanes can takeoff without flaps they are not the mechanism that causes the airplane to lift off the ground. As others have said they increase the amount of lift generated by the wing and allow it to lift off the ground at a lower speed.

As the airplane reaches takeoff speed the yoke is pulled back. This causes the elevators (located on the horizontal portion of the airplane's tail) to deflect upward. This, in turn, causes a downward force on the tail which causes the nose to lift off the ground. When the nose of the airplane rises, the angle at which the air strikes the wing increases which increases the lift of the wing. THIS is what causes the plane to fly off the ground.

That's as simple as I can explain it without using aerodynamic jargon. Hope it helped.

Answer 2

The flaps do not extend any more after take off. The yoke forces the elevator up which applies downward forces (lift) on the tail (it creates the effect of an upside down wing). Push the back down and the front goes up, its really simple. Even though an airplane doesn't look like a see saw, there is still a fulcrum called the center of gravity or CG which is normally around the wing root. Just like the playground toy, force the tail down and the nose lifts.

After takeoff, the landing gear comes up typically once the pilot is sure that if all the engines died that the aircraft could no longer make the runway, which renders an aborted takeoff useless. Once the aircraft reaches a speed called Vy which is the best combo of speed and climb over distance the flaps go up one notch. When the airplane hits Vy again the process is repeated until flaps are up. The people who fly the big iron might have a slightly different procedure, but it is generally the same thing.

Just to clear any possible confusion. Flaps are located on the inboard section of the wing and are NOT primary controlls for changing pitch (up and down flight) The elevator located in the tail does that. Flaps exist to change the airflow over the wing to alow flight at slower speeds first and foremost. Secondarily they can act as a form of air brake and while rapid deployment can can a nose up motion a pilot would only use flaps for that in an emergency in conjunction with rapid power increases only if they had no elevator or trim control.

Answer 3

flaps are set to increase the lift the wing can generate at slow speeds, as in take off. the Pilot pulls back on the yoke, which moves the elevators to the trailing edge UP position, which makes an inverted airfoil pushing DOWN on the aircraft tail and causing the nose of the aircraft to rise. The rising nose also changes the angle of attack of the wing which then allows it to generate more lift and the airplane climbs into the air. the Pilot will retract the flaps at a pre determined speed depending on the aircraft type

Answer 4

The wings create lift as air speed increases , the pilots action of pulling on the yoke turns the elevators on the tail up and forces the tail down thus changing the direction of the wing into the air and taking off.the flaps help the wing to create more lift. but as soon as the plane takes off the pilot retracts the flaps to decrease drag and accelerate , which allows the wing to produce more lift as the plane increases speed.

Answer 5

1. At lift off the flaps are not extended further.

2. Flaps are used to augment lift, thereby shortening the take off run and getting the aircraft airborne at a comparatively lower speed.

3. While rolling for take off, at a certain pre-determined speed (V1) the pilot rotates the aircraft by a slight back pressure on the control column thereby raising the nose wheeel off the ground. He holds this attitude and continues his run.

4. As the aircraft accelerates and the speed builds upto (V2) a further back pressure on the control column lifts the aircraft into the air as a result of increased angle of attack and subsequent generation of lift.

5. Both actions in Paras (3) & (4) are a result of actuating the elevators which control the pitch of the aircraft.

6. Once airborne, the pilot raises the flaps at pre-determined heights/speeds and continues to climb.

Answer 6

Flaps just help the plane generate greater lift. Flaps do not extend further when the pilot pulls back on the yoke, they stay the same until he/she decides to retract the flaps the full position (zero degrees) during the duration of climb.

Answer 7

Flaps increase the available surface of the wing meant to capture the air and give the plane LIFT--it helps decrease the speed also----on landing--it starts at 10 degrees and can be adjusted as required.

Answer 8

you don't really need the flaps to take off. an airplane can take off in a clean configuration ( no flaps) the flaps only change the shape of the wing to create more lift with less speed. so you can take off from shorter runways. and once you set the flaps for take off you don't move them anymore until you reach the apropiate alttitud and a safe airspeed. because when you retract the flaps the wing change shape and loose some of the lift .

Answer 9

The elevator, which either doubles as, or is attached to the horizontal stabilizer (the horizontal piece on the tail of the airplane) is angled down, (from back to front) by the pilot pulling on the yoke... when this angles down, it deflects air up and forces the tail of the airplane down... when the tail goes down, the front must come up... when that happens, it gives the wings some angle of attack (some air to grab hold of) and they lift the main gear off the ground...

Thats as simple as I can make it...

Answer 10

Pulling on the yoke makes the elevator deflect up, causing the air to push down on the tail of the aircraft, therefore lifting the nose. This in turn, increases the angle of attack of the wings, causing the aircraft to lift off the ground, if it has enough speed.
