What is Vr (rotation speed) for liftoff on the Diamond DA20-C1?

• A. 58 KIAS
• B. 44 KIAS
• C. 57 KIAS
• D. 60 KIAS

Answer: (B)

Vr is the airspeed at which you begin the rotation to liftoff, chosen just above the airplane’s stall speed in takeoff configuration so you can lift off safely without stalling. For the Diamond DA20-C1 in a normal takeoff (flaps up), the stall speed is around the low 40s KIAS, so the recommended rotation speed is about 44 KIAS. This gives you a smooth, controlled rotation with enough lift to leave the runway without stalling. If you rotate much faster (toward the 50s or higher), you’re starting from a higher airspeed than necessary and wasting runway, while rotating at around 44 KIAS aligns with the aircraft’s published takeoff procedure under standard conditions. Remember, Vr can shift with heavier weight, higher density altitude, or wind, but 44 KIAS is the standard reference for this airplane in normal conditions.
