In aircraft design it is important to know about stall speeds. What is a stall? Stall course when a normally laminar airflow over the airfoil, which generates your lift, becomes turbulent and ceases to produce that lift. Now, there are different design stall speeds. For example there is Vs, which indicates a clean configuration of the aircraft. Meaning that the flaps are set to zero and the gear is up. There is Vs0 which indicates a landing configuration. This indicates that the flaps are set to landing and the gear is down. Not only do stall speeds vary with configuration they also very with weight. Now, as the weight of the aircraft increases, the aircraft needs to fly faster in order to not stall. Also, with the addition of flaps, you increase the camber of the airfoil which increases the CLmax. For more information about CLmax please see our other Tamarack Teaches video. The increase in CLmax will decrease your stall speed. In conclusion, it is important to understand stall speeds to ensure safety in takeoff and landing performance.
