Which statement about takeoff speeds V1, VR, and V2 is correct?

Which statement about takeoff speeds V1, VR, and V2 is correct?

• A. V1 is rotation speed; VR is decision speed; V2 is approach speed.
• B. V1 marks the abort decision; VR is rotation begin; V2 is the minimum to climb with one engine out.
• C. V1 is the minimum speed to ensure controllability; VR is rotation speed; V2 is the speed at which the aircraft can safely climb with one engine out.
• D. V1 is the landing speed; VR is approach speed; V2 is cruise speed.

Answer: (B)

In takeoff performance, these three speeds define the sequence of decisions and actions during the roll. V1 is the abort decision speed: if an engine failure or other problem occurs before reaching V1, you should reject the takeoff; after V1 you’re committed to continue. VR is the rotation speed—the speed at which you start the nose-up rotation to lift off. V2 is the minimum speed at which the airplane can safely climb with one engine inoperative after takeoff. So the statement that V1 marks the abort decision, VR is the rotation begin, and V2 is the minimum speed to climb with one engine out correctly matches how these speeds are used in practice. The other options mix up what each speed represents (for example, V1 is not rotation speed or landing/approach/cruise speeds), which is why they’re not correct.
