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

• A. V2+20
• B. 200 knots
• C. V1
• D. Vfto

Answer: (D)

You’re looking at the speed you aim to hold during the initial climb with flaps still in the takeoff position until you reach the flap retraction altitude. That speed is Vfto. It’s chosen to give a good climb performance and enough margin to stay out of stall with the flaps extended, while setting up a smooth transition when you retract the flaps at the designated altitude. After you hit the flap retraction altitude, you retract the flaps and accelerate to the next climb speed as required by the procedure. V1 is the decision speed for the takeoff, determining whether to continue or abort, not the climb segment with flaps still out. V2+20 is a takeoff/climb performance speed used in certain engine-out scenarios, not specifically the flap retraction target. A fixed number like 200 knots isn’t the defined target for this phase, since Vfto is an aircraft‑specific parameter tied to the flap retraction altitude.
