What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
How fast does it fly on lift off?
The aircraft has to go 100 mph or more (depends on aircraft) to get off the ground in time.
How much lift does it take for an airplane to get off the ground?
In order to lift off the ground, the lift force (the upward force generated by the wings) has to be at least as great as the weight of the aircraft. Lift and weight are opposing forces and are equal in straight and level flight.
What force pulls an aircraft toward the ground acts against the force of lift in level flight?
Gravity
How space aircraft work?
well when they lift off they have this mass of fire expolding the ground which it makes it fly.
Why doesnot an air craft fall on the ground?
Because the wings generate lift as long as the aircraft is in forward motion
Why more lift is required when landing?
During landing, the purpose is to slow down the aircraft's ground speed as slow as you can without it stalling. You want to maintain Lift, not necessarily get more lift. At higher speeds, the aircraft has plenty of Lift. However during landing, the speed is slower and the angle of attack is increased to provide more Lift at lower speeds.
What force does an airplane at takeoff use more thrust or lift?
Interesting question. Lift is what actually allows an aircraft to leave the ground, but lift in a normal type aircraft (not a helicopter) is generated by forward movement through the air and that is produced by thrust. So, while lift is what's necessary to overcome gravity (weight), it's thrust that is needed to generate lift...so both forces are in play at takeoff.
How do wingless aircraft produce lift?
The only 'wingless aircraft' are helicopters. These produce lift lift from the rotor blades, which are in fact, long narrow wings.
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
What causes the lift of an airplane?
Low pressure above the wing goes faster because the low pressure always takes the longer way ( The curved side of the wing). This is what creates lift. the engines just help the airplane move on the runway to go faster for it to be able to take off. This is how it works: the fast air/low pressure on top of the wing pulls the wing towards it and since the wing is attached to the plane the plane also moves up. The slow air/high pressure always takes the short way/the bottom of wing. The high pressure going on the bottom of the wing pushes the wing upwards and the plane goes with it. This explanation of "aircraft lift" has been taught in the text books for many years but is incomplete in its explanation of "lift". If this were the complete answer to "lift" we would see no aircraft ever flying upside down as the "lift" would quickly "lift" them right into the ground. There are many aircraft used in stunt flying which have almost completely flat wings which would develop no or insufficient "lift" to keep the aircraft aloft. More recent theories point to a more complete explanation of "aircraft lift". In addition to the very small "lift" generated by the curved upper surfice of some aircraft the angle of attack to the airflow is a more complete explanation of "aircraft lift." With the huge forces necessary to lift an aircraft such as some of the military cargo planes the amount of "lift" generated by the curved wing design would never be sufficient to get it off the ground let alone stay aloft, however the angle of attack through the air generating force on the lower surface of the wing can generate sufficient lift to get the aircraft off the ground. To some extent the greater the angle of attack the greater lift.
Why doesn't an aircraft fall on the ground?
Actually, aircraft could fall on the ground if it's stalling (losing speed). The reason why their aren't any airplanes fall on the ground now is because most of the airplanes could warn the pilots if the aircraft is stalling and so the pilots will know they have to increase the speed.
