VMCG with Flaps 2 equals what value?

VMCG with Flaps 2 equals what value?

• A. 87 knots
• B. 89 knots
• C. 91 knots
• D. 93 knots

Answer: (C)

VMCG is the minimum speed on the runway at which you can maintain directional control with one engine inoperative, while the remaining engine is producing takeoff thrust. Flap setting changes how the airplane behaves on the ground with an engine out because it alters lift, drag, and rudder effectiveness. With Flaps 2, the balance of these factors requires a slightly higher minimum controllable speed to keep the airplane straight and prevent uncontrolled yaw. The value shown for that flap setting is 91 knots, which is why this option is the correct one for Flaps 2. The other numbers correspond to different flap configurations and wouldn’t apply here.
