Vertical takeoff and landing (VTOL) refers to aircraft that can take off, hover, and land vertically. This capability allows them to operate in confined spaces where traditional runways are not available. VTOL aircraft can be powered by various technologies, including rotors, tilt-rotors, and jet engines. VTOL is commonly used in military applications, such as the Bell Boeing V-22 Osprey, and in urban air mobility solutions. These aircraft are designed to improve transportation efficiency, reduce congestion, and provide quick access to remote areas. As technology advances, VTOL is becoming increasingly relevant in commercial aviation.
