What is the purpose of a stall warning system?

The purpose of a stall warning system is to alert pilots before an approaching stall condition. This system plays a crucial role in flight safety, as it provides warnings that help pilots recognize when the aircraft is at risk of stalling—a situation where the wings are unable to generate enough lift due to inadequate airflow, typically caused by an excessive angle of attack. By receiving a timely alert from the stall warning system, pilots can take appropriate action, such as reducing the angle of attack or increasing power, to prevent the stall from occurring, thereby maintaining control of the aircraft and ensuring safe operation.
