On initial climb with the flaps extended to the takeoff flap setting full maneuvering capability is available at _____.

• A. V2
• B. V2+20
• C. V2+10
• D. V1+10

Answer: (B)

Full maneuvering capability means you have enough airspeed to apply full control inputs and stay within structural limits while the takeoff flaps are still extended. When flaps are in the takeoff setting, lift is aided but drag is higher and control effectiveness is reduced, so you need extra speed to regain full control authority and margin above stall. You reach that level of control at V2 plus a safety margin, which in this context is about 20 knots. So V2+20 gives the necessary margin for maintaining directional and pitch control during the initial climb with flaps still set for takeoff. The lower speeds would not provide sufficient control margin with the flaps out, and V1+10 relates to a takeoff decision speed, not to attainable maneuvering capability once the airplane is airborne.
