At take-off,the plane麓s nose lifts first then the whole body.Explain to me How and Why.?

Before getting fully airborne,the plane麓s nose lifts up first before the rest of the body.Who can explain to me by what mechanism it is accomplished.


I want to study aeronautics.|||The plane has to lift the nose up first to create the "Angle Of Attack".


The angle of attack is the angle created from the wings to the motion of the air which is called relative airflow.


The air for example is straight into the airplane and the wings must angle upwards to create lift.


To do this pilot gently pulls back on the stick to deflect the elevator upwards which pulls the nose up.


This creates the low pressure required over the wing which in turn creates the high pressure under the wing to create lift.|||on a tail dragger the tail lifts off first. depends on center of gravity, a differance of air pressure on the air foil surfaces is produced causing lift, the center of gravity lifts last.|||Pitch has got it correct.


If the elevator deflects down as barry says, you would eat asphalt.


He can't be a commercial pilot if he presumes a jet is the same as a single engine.


Aerodynamics is just that. It doesn't change from plane to plane.|||Where do these answers come from?


Barry is totally wrong. If the elevator deflects down, on any plane the nose goes down.


fci_pitch explained it pretty well.


The difference in pressure form the bottom of the wing to the top is how lift is created.


The nose has to come up to create the angle of attack.


A tail dragger is normally in that position, and yes it may lift the tail off first but it is not necessary. A tail dragger is better on grass strips because you can lift the tail up so less friction is created from the grass.


I have lifted off from all three wheels. No biggee.


If you lift the tail up first you still have to pull the nose up to create the angle of attack for the lift.|||On the tail of fixed-wing aircraft, there there are 2 stabilizers. One is the vertical stabilizer with the rudder flight control %26amp; the


other is the horizontal stabilizer with the elevator flight control. The elevator is the flight control which causes the aircraft's nose


to lift up off the ground first then the fuselage. The pilot accomp-


lishes this by pulling back on the flight control yoke or stick to gain altitude. Pushing forward on the yoke or stick decreases al-


titude causing the nose to drop. Try this simple excersise. Place


your 2 index fingers touching tip to tip. Keeping one finger still,


move the other finger up %26amp; down. This works like a hinge. The


upward position of your finger or "elevator causes the craft to go


up %26amp; the downward position of your finger or "elevator causes the craft to go down. Goodluck with your career.|||How: They throw the throttle into full than pull back on the control lever. Why: This is what allows the aircraft to become airborne. I am sure after long enough of moving forward at full throttle, it will begin to lift off the ground, but they pull back on the control stick so this occurs before the runway ends!


Good question!


Tyler|||Here is what you need to know, ill use an example for a big jet since this is more interesting:





there are different takeoffs speeds for different weights, aircraft, etc..





lets say the take off speed is 145knots, the pilot pitches up (around 10 degrees no more) before reaching this airspeed, the pitch which is caused by the elevator deflecting airflow upward enables the angle of attack to increase and lift increases, now the airplane becomes airborne because the wing is producing lift equal to weight of the aircraft, there is enough airflow now over the wing.





thats it it, lift equals weight, that is the only way to become airborne, the nose must pitch up first because the angle of atttack must be positive not negative.





look up angle of attack...this will get you started. then i suggest buying "aerodynamics for naval aviators" for $18, is a must have.|||LOOKY HERE, as Bob Hoover said,,V-1,Rotate,V-2,Liftoff, then invert, adjust the manifold prsr, establish a positive climb, and then open the vodka, and enjoy !!!! OK "pitch" is correct, anyone who describes the yoke, or stick, as a "lever" needs to get some time in an a/c.... or sit on a block of cheese, and swallow a mouse,,,,AM|||for something to fly its all about lift drag thrust and gravity you need more lift than gravity the force pushing down on the aircraft, and more trust than drag to go forward





f-16 jet aircraft avionics tech 4 years military|||usually airplanes rotate just before the moment of the lift-off this rotation is caused by an aerodynamic force that push the tail down, so the nose lifts up. This because the elevator is turned up by the pilot that pull(to himself) the stick.


When the plane make this rotation the lift grows suddenly because the angle of attack has grown.


Not all airplanes rotate, some can't because its landing gear is not good for rotation ad rotation would cause the tail hit the ground.For example B-52 (and motorized sailplanes) can't rotate, they must keep accelerating until they are fast enough to lift-off without rotating.


This rare kind of take-off needs very long runways, so when rotation is possible it is preferred.|||They pull on the throttle for power and control the pitch of the plane by the flaps on the wings.
