본문내용
One of the most spectacular things to view is the structure and the body of an aero plane. Its concept has always been scintillating and technical. It all started with the answer to how birds can fly. All of us do know that only when an object overcomes the earth’s natural gravitational pull, it tends to fly. The wing of an aircraft helps in gliding it through the wind and also in its landing and takeoff.

Maintaining a steady flight requires a balance, often described as an equilibrium of all the forces acting upon an airplane. Weight, lift, thrust and drag are the acting forces on an airplane. Assuming a straight and level flight, lift must be equal to weight and drag must be equal to thrust.
If lift becomes greater than weight, then the plane will accelerate upward.
If the weight is greater than the lift, then the plane will accelerate downward.
When the thrust becomes greater than the drag, the plane will accelerate forward. If drag becomes greater than the thrust a deceleration will occur.
