Which term refers to an aircraft kept aloft by aerodynamic forces and propulsion?

• A. Airplane
• B. Aircraft
• C. Altitude
• D. Air

Answer: (A)

A fixed-wing powered flyer is called an airplane. It’s designed to stay aloft by lift generated over its wings as air moves past them, while propulsion provides the forward thrust needed to overcome drag. When lift balances weight and thrust balances drag, the airplane can fly sustained in the atmosphere. The broader word “aircraft” would cover any flying machine, including helicopters, gliders, or balloons, not just fixed-wing airplanes. Altitude is simply height, and air is the surrounding atmosphere, not a vehicle. So the term that best fits the description of a vehicle kept aloft by aerodynamic forces and propulsion is airplane.
