Using light-weight materials, an aerodynamic design, power source to get the plane off the ground will all help. Probably the biggest thing a plane needs is enough lift from the wings. The shape of the wing helps create this lift. The wing's profile kind of looks like a tear drop that is flat on the bottom and curved on the top tapering to a point to the rear of the wing. If I remember correctly, this profile creates an area of high pressure on the underside of the wing compared to a lower pressure on top of the wing. This is what creates the lift for the plane. Of course you have to maintain a proper speed to maintain this lift in order to keep the plane in the air...Hope that helps.
There is no specific age requirement to fly on an airplane. Infants can fly as long as they are accompanied by a parent or guardian. Airlines may have their own policies regarding unaccompanied minors.
No, the Lego Technic jet plane model does not actually fly. It is a static model designed for display and play purposes rather than for actual flight.
I'm not sure what you mean by "need" since weight is a concomitant - everything used to construct an aircraft has weight. It's a fact of life.Aircraft designers do everything possible to reduceweight.
A plane can fly upside down by generating enough lift from its wings to counteract the force of gravity pulling it towards the ground. This requires precise control of the plane's speed, angle of attack, and other factors to maintain stability and control while inverted. Pilots use specialized training and techniques to safely fly a plane upside down.
Planes fly by generating lift from the wings as they move through the air. This lift is created by the shape of the wings and the speed at which the plane is moving. Engines provide the necessary thrust to propel the plane forward.
You can't fly. You will need a jet pack or plane. there is no other way
well it will need to make the forces unequal to take off, but yes it can fly with them all equal.
A piece of paper
They made the first plane to fly in air in 1903.
Bord a plane.
Well... they need to know how to fly a plane
Yes.
Fly in Austrailia
you must know how to navigate,operate and monitor your plane.
no
It makes the plane weigh more.
Basically, Wings provide lift to fly Elevators make the plane point(fly) up and down. Ailerons make the plane bank. The rudder turns the nose of the plane.
