What is the target airspeed after reaching MFRA?

• A. Vfto
• B. Vref
• C. V2
• D. Vs

Answer: (C)

Focusing on the takeoff profile, reaching MFRA marks the point where you switch to the takeoff safety speed regime. The target airspeed at that stage is V2. V2 is defined as the minimum takeoff safety speed with one engine inoperative, giving you enough control authority and climb capability to continue the takeoff safely or to abort if needed. It provides the necessary margin above stall (and above slower, less controllable speeds) to maintain a positive rate of climb with a degraded engine. Vs is the stall speed, which is far too slow for takeoff and would risk loss of lift if maintained after liftoff. Vref is the approach/landing reference speed, not used during the takeoff climb. The other speed shown (Vfto or similar) isn’t the speed used after MFRA for the standard takeoff profile. So V2 is the correct target.
