Which characteristic is NOT typically associated with rotor-based UAS?

The characteristic of needing a runway is not typically associated with rotor-based Unmanned Aircraft Systems (UAS). Rotor-based UAS, such as helicopters and multirotors, are designed to take off and land vertically, which allows them to operate in confined spaces without the need for a traditional runway. This capability enables rotor-based UAS to access areas where fixed-wing aircraft cannot operate effectively.

In contrast, the other characteristics—hovering capability, vertical takeoff, and high maneuverability—are integral to rotor-based designs. These systems can hover in place, ascend and descend vertically, and maneuver quickly in various directions, making them advantageous for applications requiring precision and agility.
