What is the Vy speed in cruise configuration?

• A. 60 KIAS
• B. 75 KIAS
• C. 57 KIAS
• D. 58 KIAS

Answer: (B)

Vy is the speed that gives the greatest rate of climb, meaning the airplane climbs fastest per unit time. For the DA20-C1 in cruise (clean) configuration, about 75 knots indicated airspeed provides the best balance of lift and drag with the engine’s available power, yielding the maximum vertical speed. If you fly much slower, you get close to stall and lose excess power, reducing climb rate. If you fly much faster, drag rises and the climb rate also drops. So the commonly cited value for Vy in clean configuration is 75 KIAS. Remember, Vy can shift with weight and altitude, but this is the typical value for standard conditions.
