Slow flight is primarily taught to help pilots become familiar with:

The primary focus of slow flight training is to help pilots become familiar with the feel and sounds of an approaching stall. During slow flight, pilots intentionally operate the aircraft at low airspeeds, just above the stall threshold. This training is crucial because it teaches pilots to recognize the signs of an impending stall, such as changes in control responsiveness, aircraft handling characteristics, and even auditory cues, like the sound of airflow changes over the wings.

By experiencing slow flight, pilots develop a better understanding of their aircraft's performance margins, allowing them to respond appropriately in real-life situations where slower flight is necessary, such as during landing approaches or when encountering unexpected turbulence. This foundation is essential for safe flying practices, as it equips pilots with the intuition and muscle memory needed to avoid stalling and to execute recovery procedures effectively should a stall occur.
