Vmca criteria include which item?

• A. Bank angle no more than 5°
• B. Visual reference near ground
• C. Cabin pressure altitude
• D. Landing gear configuration

Answer: (A)

Vmca is the minimum control speed with one engine inoperative, ensuring you can still maintain direction and stay in control of the airplane under an engine-out condition. The key requirement is that the bank angle be kept very shallow, typically no more than five degrees. This small bank limit helps keep rudder effectiveness high enough to counter the yaw produced by the operating engine and the asymmetry from the failed engine. If you bank more than a tiny amount, the combination of yaw and roll moments can overwhelm the rudder, making it harder to control the aircraft.

The other items listed don’t define Vmca. Visual reference near the ground isn’t what sets this speed, and cabin pressure altitude or landing gear configuration pertain to other aspects of flight or systems performance, not the controllability with one engine out at this speed.
