What is the stall speed (Vs) for standard aircraft configurations?

The stall speed (Vs) for standard aircraft configurations is typically defined as the minimum speed at which an aircraft can maintain controlled flight in a straight and level attitude. For most light aircraft under standard configurations, stall speeds generally fall within a range that aligns with the provided choices. The correct value of 48 KIAS aligns with average stall speeds for many general aviation airplanes, particularly those commonly used for training, which are designed to operate within safe performance margins.

Stall speed can vary based on factors like aircraft weight, configuration (flaps, landing gear position), and environmental conditions, but in a standardized setting, 48 KIAS is a reasonable reference point for a typical aircraft in training scenarios. This speed is also useful for pilots to remember when considering takeoff and landing operations, as it provides a benchmark to ensure adequate safety margins during flight maneuvers.
