What does the term 'stall speed' refer to in aviation?

The term 'stall speed' in aviation refers specifically to the minimum speed at which an aircraft must fly in order to generate enough lift to maintain level flight. Below this speed, the wings can no longer produce sufficient lift to counteract the weight of the aircraft, leading to a stall. This is a critical aspect of flight safety, as flying below stall speed can result in loss of control.

Maintaining an altitude requires that the aircraft exceeds this stall speed; otherwise, it risks entering a stall condition. This concept is fundamental for pilots to grasp, as it directly influences decisions regarding approach, landing, and overall aircraft performance during various phases of flight.
