What is the Vx speed for takeoff on the Diamond DA20-C1?

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

Answer: (A)

Vx is the speed that gives the steepest angle of climb, meaning the airplane gains the most altitude for each mile of forward travel. On the Diamond DA20-C1, the published takeoff Vx under standard-day, light-weight, takeoff configuration is about 57 KIAS. That speed enables you to climb most steeply right after liftoff, which is precisely why you’d use it when obstacles are a concern. As you clear the obstacle, you’d accelerate toward Vy to maximize climb rate rather than angle. Remember, Vx can shift with weight, altitude, temperature, and flap/gear settings, but 57 KIAS is the standard value for this aircraft.
