Usage: technical; engineering/aviation context; plural form

Examples

• The aircraft's overstabilities made it difficult for pilots to execute precise maneuvers.
• Engineers identified several overstabilities in the control system that reduced responsiveness.
• Excessive overstabilities in the suspension design caused the vehicle to feel sluggish.
• The feedback loop created overstabilities that prevented the system from reaching equilibrium quickly.
