What does VX represent in flight performance?

• A. Best Rate of Climb
• B. Best Angle of Climb
• C. Maximum Structural Cruising
• D. Never Exceed Speed

Answer: (B)

VX is the airspeed that gives the greatest altitude gain for a given horizontal distance, meaning the steepest climb angle. This speed is used when you need to clear an obstacle or minimize ground distance required to reach a safe height after takeoff. It’s typically found just above stall, balancing lift and can be limited by aircraft power and drag to maximize climb angle rather than climb rate. In contrast, the best rate of climb speed focuses on altitude gained per unit time, not distance. Never Exceed Speed is a structural limit, not a climbperformance value, and the term maximum structural cruising isn’t used for this purpose.
