An aircraft is a vehicle which is able to fly through the air (or through any other atmosphere). All the human activity which surrounds aircraft is called aviation. (Most rocket vehicles are not aircraft because they are not supported by the surrounding air). Manned aircraft are flown by a pilot. Unmanned aircraft are traditionally called drones, while the term RPV (remote piloted vehicle) has recently become common in modern military circles.
Aircraft fall into two broad categories: Lighter-than-air, called aerostats, and heavier-than-air, called aerodynes.
Aeroplanes or Airplanes are technically called fixed-wing aircraft.
Aeroplanes are generally characterized by their wing configuration.
