Stall speed for takeoff (Vs1) is which value (KIAS)?

Stall speed for takeoff (Vs1) is which value (KIAS)?

• A. 40 KIAS
• B. 36 KIAS
• C. 60 KIAS
• D. 64 KIAS

Answer: (A)

The speed at which the airplane becomes just capable of maintaining steady flight in the takeoff configuration is what Vs1 represents. It’s the minimum controllable stall speed you should be above during the takeoff phase so you can safely rotate and establish a climb. For the DA20-C1, the published takeoff-configuration stall speed is 40 KIAS. That means, with the takeoff configuration used on this airplane (the configuration defined in the POH for takeoff), you should reach at least 40 knots indicated airspeed before rotation to avoid stalling before liftoff and to ensure you have controllability as you begin the takeoff climb. The other speeds listed don’t reflect the takeoff-configuration stall speed for this aircraft. They may correspond to stall speeds in other configurations or to speeds used for different phases, but the official takeoff-stall value for the DA20-C1 is 40 KIAS.
