"操纵的灵敏性" can be translated into English as "maneuverability" or "handling sensitivity".
Maneuverability is a more general term that refers to the ease and precision with which a vehicle, machine, or system can be controlled or directed. It is often used in the context of aircraft, ships, or vehicles to describe their ability to change direction, speed, or position quickly and accurately.
Handling sensitivity emphasizes the responsiveness and precision of the controls, indicating how sensitive the system is to the operator's inputs. This term might be more appropriate when discussing the fine control aspects of a device or machine.
In most contexts, especially when referring to the overall ease and precision of control, "maneuverability" would be a suitable and commonly used translation for "操纵的灵敏性".
