What is the lower limit of the normal operating airspeed range for the DA20-C1?

• A. 118 KIAS
• B. 164 KIAS
• C. 188 KIAS
• D. 44 KIAS

Answer: (D)

The lower limit of the normal operating airspeed range is the stall speed in clean configuration, which defines the minimum safe speed for normal flight. For the DA20-C1, that clean-stall speed (Vs1) is 44 knots indicated airspeed, so the green arc on the airspeed indicator starts at 44 KIAS. Flying slower than this increases the risk of a stall unless you change configuration or power. In practice, you maintain above this speed, and in turns or with added load, you’ll need even more airspeed to stay out of stall. The other numbers are speeds associated with higher, non-normal regimes and aren’t the lower limit.
