Define 'stall speed' and its relevance to flight safety.

Stall speed is defined as the minimum speed at which an aircraft can maintain level flight. It is a crucial parameter in the realm of aviation, as it directly impacts safety during critical phases of flight such as takeoff and landing. When an aircraft flies below its stall speed, it can no longer generate sufficient lift to counteract gravity, leading to a stall condition.

Understanding stall speed is essential for pilots, as it assists in determining safe operational limits and speeds during various maneuvers. During takeoff, pilots must ensure they reach a speed above stall speed to achieve lift and safely ascend. Similarly, during landing, maintaining control requires awareness of stall speed to avoid entering a stall while approaching the runway. Therefore, comprehending and adhering to stall speed guidelines is vital for enhancing flight safety and preventing accidents associated with loss of control.
