Which speed is defined as the minimum takeoff safety speed?

• A. V1
• B. VR
• C. V2
• D. Cruise climb speed.

Answer: (C)

Takeoff V speeds define performance limits during the takeoff. The minimum takeoff safety speed is V2. V2 is the speed at which the airplane can safely continue the takeoff with one engine inoperative and achieve the required climb gradient, ensuring proper obstacle clearance and stall margin after liftoff. It represents a safety threshold for climb performance that must be met by the time you reach liftoff and begin the initial climb. In contrast, V1 is the speed at which you decide to continue or abort the takeoff, and VR is the rotation speed at which you lift the nose. Cruise climb speed relates to the en-route phase, not to the takeoff, so it does not define this parameter.
