For the approach with flaps in landing configuration, what is the actual approach speed (KIAS)?

• A. 60 KIAS
• B. 64 KIAS
• C. 55 KIAS
• D. 52 KIAS

Answer: (C)

Approach speed is the indicated airspeed chosen on final approach to stay well above stall while still being controllable with the landing configuration. With flaps in the landing position, you use a safety margin over the stall speed in that configuration. A common target is about 1.3 times the stall speed for that flap setting. For the DA20-C1, the stall speed with landing flaps is in the low 40s KIAS, so 1.3 × ~42 KIAS gives about 55 KIAS. That’s why the best choice is 55 KIAS. Falling to a lower speed can erode margin and stability, while higher speeds reduce energy management on approach.
