Which speed is described as the targeted speed to be flown after flap retraction altitude?

• A. 200 knots
• B. Vref
• C. V2+20
• D. Vmo

Answer: (A)

After flap retraction altitude, the aircraft is in clean configuration, so you accelerate to a practical target speed that gives you good climb performance and a safe stall margin. The standard target in this scenario is 200 knots. This speed sits well above the stall speed with flaps up, providing comfortable handling and room to maneuver, while staying under structural limits and not wasting excess drag. It’s fast enough to improve climb efficiency but not so fast that you risk overspeed before you reach cruising conditions. Other speeds are tied to different phases of flight. Vref is the landing approach speed, not the post-retraction climb target. V2+20 relates to takeoff performance and initial climb with an engine-inoperative scenario, not the post-flap-retraction phase. Vmo is the maximum operating speed you must not exceed, not a target speed for this phase.
