What is the Meaning & Definition of airplane

An airplane, also known with the term's most popular use of aircraft is an aircraft, i.e. a ship that moves through the sky and the air and which is much heavier than the latter which can sustain on its own. Its most salient features include the provision of a fixed-wing, one or more engines and a load space, or failing to the permanence of passengers.
Basically the airplane works thanks to the aerodynamics generated on their wings, with an uphill and is known as stall.
It should be noted that this force is generated as a result of the difference in pressures that mediates between the top and bottom of the wing and wing design which produces directly.
Since ancient times the man was seduced by the idea of flying and then, for thousands of years focused its efforts in order to achieve results in this regard. Although the road was slow and sinuous, gradually got various innovations that led to the technology that we have today and that allows human beings use to the airplane to move by various parties of the world in fast and easy way.
The first remarkable contribution in this regard occurred in the year 1883, when John Montgomery made a flight through a machine that weighed more than the air-controlled: the glider.
The airplane can be monoplane (only have two wings), biplane (presents fixed-wing with two groups of these, some arranged on the fuselage and the other pair below) or triplane (also fixed wing but has three wings, which are arranged one on top of the other groups).
On the other hand, airplanes, depending on the use that feature, are usually classified in the following way: civil (because they transport goods, passengers, fighting fires, they involved in some activity type health or training) and military (perform loading and transport of militia and weaponry, among other military activities).
Since its inception, the airplane has historically been an instrument recurrently used in the field military with various missions.
