What is one primary advantage rotary-wing aircraft have over fixed-wing aircraft?

Rotary-wing aircraft, such as helicopters, have the primary advantage of Vertical Takeoff and Landing (VTOL). This capability allows them to ascend and descend vertically, which means they do not require long runways like fixed-wing aircraft. This enhances operational flexibility, enabling them to take off and land in confined spaces, such as urban environments, mountainous regions, or areas lacking substantial infrastructure.

This advantage is particularly useful in various applications such as search and rescue operations, emergency medical services, and military operations, where quick and agile responses are crucial. While fixed-wing aircraft may surpass rotary-wing aircraft in speed, altitude, and flight duration, the ability to perform VTOL significantly broadens the operational scope and accessibility of rotary-wing aircraft, making them versatile tools in many scenarios.
