When discussing aircraft, it is important to consider that the term covers both fixed-wing and rotary-wing variations. Airplanes are a common example of fixed-wing aircraft, featuring rigid wings and powerful engines that allow them to create ample lift for long distance flight. Meanwhile, helicopters are the most notable form of rotary-wing aircraft, and they utilize an assembly of rotary blades that rapidly spin around a centralized mass atop the fuselage to create lift. With these two distinct forms of flight, it is only natural that both forms of aircraft widely differ in their capabilities. One of the biggest differences between airplanes and helicopters is the ability to hover and stand still in the air at any point in flight, an ability that is generally not held by vehicles with airplane wings.
