Stability Margin

Stability margin refers to how much a system, such as an aircraft or a control process, can tolerate changes or disturbances before becoming unstable or unpredictable. It measures the safety buffer between current operating conditions and the point where the system might lose control or behave erratically. A larger stability margin indicates a more robust system capable of handling unexpected variations, while a smaller margin suggests closer proximity to instability. In essence, it’s a way to gauge how securely a system can operate while still remaining stable under potential disturbances.
