What is the Vr range for rotation as given?

• A. 60-75
• B. 65-80
• C. 70-85
• D. 75-90

Answer: (C)

Vr is the speed at which you start the takeoff rotation. For the PC-12 NGX, the range you should target is about 70 to 85 knots. This window balances having enough wing lift to lift off smoothly with a controlled, gradual pitch into the climb, while avoiding an overly aggressive rotation that could lead to excessive nose-up attitude, longer takeoff run, or potential tail or elevator issues.

That range is provided to cover variations in weight, density altitude, and configuration. At heavier weights or higher density altitudes, Vr trends toward the upper end, whereas lighter conditions may be closer to the lower end. Rotating below 70 knots can give insufficient lift margin and a longer takeoff distance, while rotating above 85 knots increases the risk of abrupt rotation and control difficulties.
