VMC

Question 1

How does VMC change with respect to controllability and performance?

Answer 1

• VMC increases by 3 knots for every degree of bank below 5 degrees.
• VMC increases as the CG moves aft due to reduced rudder effectiveness
• VMC is higher at lower density altitudes due to increased engine performance
• VMC increases as weight decreases due to reduced inertia

*VMC increases when inop engine is unfeathered due to increased drag and when operating engine is at full power
